    Whether it’s an astronomical discovery, news of a previously undiscovered disease or a major report about climate change, science is often making headlines.

    This means that it’s perhaps more important than ever for scientists to visibly engage with society. By becoming recognisable figures in the media, scientists can share new ideas and influence science policy. They can also shape public opinion, and build public trust in science, offering hope in times of crisis. They’re important players in the fight against misinformation, pseudoscience and anti-science sentiments.

    Some scientists have become publicly visible, regularly appearing in the media. Some have become media stars. There are even a few scientific celebrities.

    But, as our recently published paper reveals, even these supposedly visible scientists aren’t that recognisable to many. We surveyed 1,000 respondents in South Africa and another 1,000 in Germany, asking people to name up to three living scientists in their own country. More than half in both countries didn’t reply, said they didn’t know or couldn’t remember.

    We also asked people to explain what they thought of as a “visible” scientist and what they expected of those scientists.

    This kind of research helps to explain the relationship between science and society. It also helps policymakers, science communicators and institutions understand how best to support scientists to play a more prominent role in the public interest.

    Not all that visible

    When asked to name a living scientist from their own country, more than half of the respondents in both countries did not reply. Or they wrote something like “I don’t know” or “I can’t remember”. Many who did answer listed the names of deceased scientists such as German-born theoretical physicist Albert Einstein, US astronomer Carl Sagan, and South African heart surgeon Christiaan Barnard.

    Several South Africans thought of politicians such as former president Jacob Zuma or former health minister Zweli Mkhize as visible scientists. Others named tech entrepreneurs who no longer live in South Africa, like Mark Shuttleworth and Elon Musk. This indicates that whoever publicly talks about science can easily be perceived as a scientist.

    Controversial doctor Wouter Basson was mentioned several times. Basson, a cardiologist, headed the apartheid government’s secret chemical and biological warfare project, Project Coast, and was nicknamed “Dr Death” in the media because of his alleged role in the deaths of anti-apartheid activists. (In 2002 he was acquitted of 67 charges related to his involvement in apartheid-era crimes.) A public outcry erupted when it emerged, in 2021, that he had been practising as a cardiologist at a local private hospital since 2005. The fact that he was mentioned by respondents confirms that there’s a link between controversy and perceived public visibility.

    Most living scientists mentioned were health researchers who achieved a high media profile during COVID-19, such as the German virologist Christian Drosten and South African HIV/Aids experts Linda-Gail Bekker, Salim Abdool Karim and Glenda Gray.

    This demonstrates that, overall, scientists are invisible rather than visible in public. The visible scientist is – and remains – a rare phenomenon despite changing media environments and a recent global pandemic.

    Expectations

    Echoing other researchers’ earlier findings, the study shows that people expect a visible scientist to have a solid professional reputation. They should also be charismatic leaders who are highly articulate, media-savvy, hard-working and dedicated. Some South Africans emphasised that visible scientists should put the needs of others before their own and that science should serve all citizens equally.

    Respondents from Germany and South Africa generally agreed that visible scientists should always base their comments on robust evidence and always tell the truth, even if it was difficult. They should not operate too closely to politics and should serve the public without hidden agendas and vested interests.

    Earlier studies have shown that the most visible scientists are usually men in leadership positions. Our survey found that people didn’t mind what a visible scientist looked like, and did not prefer a specific gender or seniority. This suggests that there is scope for younger and female scientists to become more visible in the public sphere.

    We found only minor differences between South Africa and Germany. Public expectations of scientists are remarkably similar across these two countries from the global north and the global south. The overall similar attitudes towards visible scientists may be explained by a universal public image of science around the world.

    Increasing visibility

    The study was part of the crowd-sourced Many Labs project “Trust in Science and Science-Related Populism”. The project’s findings on public trust in scientists across 68 countries show that, overall, public trust in science remains high. It also highlighted that people worldwide want scientists to engage more proactively with society and play a more prominent role in evidence-based policymaking.

  • MIL-OSI Submissions: Global crises have hit education hard: 24 years of research offers a way forward for southern Africa

    Source: The Conversation – Africa – By Emmanuel Ojo, Associate Professor, University of the Witwatersrand

    Global crises have shaped our world over the past two decades, affecting education systems everywhere. Higher education researcher Emmanuel Ojo has studied the impact of these disruptions on educational opportunities, particularly in southern Africa.

    He looked at 5,511 peer-reviewed articles published between 2000 and 2024 to explore what the research suggests about making education systems more resilient. Here, he answers some questions about his review.

    What are the global crises that have undermined education?

    In my review I drew up a table documenting how multiple crises have disrupted education systems worldwide.

    The cycle began with the 2000-2002 dot-com bubble collapse, which reduced education funding and slowed technological integration. This was followed by the 2001 terrorist attacks, Severe Acute Respiratory Syndrome (SARS) outbreak (2002-2004), Iraq War (2003-2011), Indian Ocean tsunami (2004), and Hurricane Katrina (2005). The Israeli-Palestinian conflict since 2000, global food crisis (2007-2008), financial crisis (2007-2008), and European debt crisis (2010-2012) continued this pattern of disruption.

    More recently, the Ebola epidemic, COVID-19 pandemic, and Russia-Ukraine war have destabilised education systems. Meanwhile, the ongoing climate crisis creates challenges, particularly in southern Africa where environmental vulnerability is high.

    Who suffers most, and in what ways?

    Education has consistently been among the hardest-hit sectors globally. According to Unesco, the COVID pandemic alone affected more than 1.6 billion students worldwide.

    But the impact is not distributed equally.

    My research shows crises have put vulnerable populations at a further disadvantage through school closures, funding diversions, infrastructure destruction and student displacement. Quality and access decline most sharply for marginalised communities. Costs rise and mobility is restricted. Food insecurity during crises reduces attendance among the poorest students.

    In southern Africa, the Covid-19 disruption highlighted existing divides. Privileged students continued learning online. Those in rural and informal settlements were completely cut off from education.

    Climate change compounds these inequalities. Unicef highlights that climate disasters have a disproportionate impact on schooling for millions in low-income countries, where adaptive infrastructure is limited.

    What’s at stake for southern Africa is the region’s development potential and social cohesion. The widening of educational divides threatens to create a generation with unequal opportunities and capabilities.

    What makes southern African education systems fragile?

    My review focused on the 16 countries of the Southern African Development Community, revealing what makes them vulnerable to crisis impacts.

    Southern Africa’s geographic exposure to climate disasters combines with pre-existing economic inequalities. The region’s digital divide became starkly visible during the Covid-19 pandemic. Some students were excluded from learning by limited connectivity and unreliable electricity.

    The region’s systems also rely on external funding. The Trump administration’s sudden foreign aid freeze was a shock to South Africa’s higher education sector. It has affected public health initiatives and university research programmes.

    Research representation itself is unequal. Within the region, South African researchers dominate and other nations make only limited contributions. This creates blind spots in understanding context-specific challenges and solutions.

    Each successive crisis deepens educational divides, making recovery increasingly difficult and costly. Weaker education systems make the region less able to respond to other development challenges, too.

    How can southern Africa build education systems to withstand crises?

    One striking finding from my review was the surge in educational research after the Covid-19 pandemic began – from 229 studies in 2019 to nearly double that in 2020, with continued rapid growth thereafter. This indicates growing recognition that education systems must be redesigned to withstand future disruptions, not merely recover from current ones.

    Research points to a number of ways to do this:

    • Strategic investment in educational infrastructure, particularly digital technologies, to ensure learning continuity.

    • Equipping educators with skills to adapt teaching methods during emergencies.

    • Innovative, context-appropriate teaching approaches that empower communities.

    • Integration of indigenous knowledge systems into curricula, enhancing relevance, adaptability and community ownership.

    • Interdisciplinary and cross-national research collaborations.

    • Protection of education budgets, recognising education’s role in crisis recovery and long-term stability.

    • Community engagement in education, ensuring interventions are culturally appropriate and widely accepted.

    In my view, African philanthropists have a duty to provide the independent financial base that education systems need to withstand external funding fluctuations.

    What’s the cost of doing nothing?

    The economic and social costs of failing to build resilient education systems are profound and long-lasting. Each educational disruption creates negative effects that extend far beyond the crisis period.

    When students miss critical learning periods, it reduces their chances in life. The World Bank estimates that learning losses from the Covid-19 pandemic alone could result in up to US$17 trillion in lost lifetime earnings for affected students globally.

    Social costs are equally severe. Educational disruptions increase dropout rates, child marriage, early pregnancy, and youth unemployment. These outcomes create broader societal challenges that require costly interventions across multiple sectors.

    Spending on educational resilience avoids those costs.

    The question isn’t whether southern African nations can afford to invest in educational resilience, but whether they can afford not to.

    The choices made today will determine whether education systems merely survive crises or make society better. Evidence-based policies and regional cooperation are essential for building education systems that can fulfil Southern Africa’s human potential.

  • MIL-OSI Submissions: Sustainable economic growth in South Africa will come from renewables, not coal: what our model shows

    Source: The Conversation – Africa – By Andrew Phiri, Associate Professor of Economics, Nelson Mandela University

    Coal fired power stations produce 85% of South Africa’s electricity, making the country the biggest producer of harmful greenhouse-gas emissions in Africa. To move away from coal and meet its commitment to reaching net zero emissions by 2050, South Africa needs to dramatically increase production of renewable energy. New research by economics associate professor Andrew Phiri looked at the relationship between renewable and non-renewable energy consumption and GDP growth in South Africa to find out which energy source is most compatible with economic development.

    Non-renewables, renewables and economic growth: what’s there to know?

    We set out to discover whether renewable energy in South Africa, such as wind or solar power, supports sustainable economic growth. We also wanted to find out if renewables can replace non-renewable energy as a source and enabler of economic growth.

    Together with student Tsepiso Sesoai, I did research comparing the impact of renewable and non-renewable energy on economic growth in South Africa.

    South Africa currently faces a dual challenge when it comes to energy. It is heavily dependent on non-renewable energy (coal), which also worsens global warming and speeds up climate change. But it desperately needs to grow the economy at a faster rate, given very high unemployment, poverty and inequality.

    It’s therefore important to find out whether South Africa would be able to make a smooth transition from non-renewable energy to cleaner energy, and grow the economy at the same time.

    Past studies have looked into the role of energy in South Africa’s economic growth, but their methods have provided only limited information about whether South Africa can make a smooth transition from dirty to clean energy.

    African economic expansion need not threaten global carbon targets: study points out the path to green growth

    To get a deeper understanding, we conducted a modelling exercise. We used an analytical tool called “continuous complex wavelets” to see how renewable and non-renewable energy influences growth over time.

    Our model shows that an increased supply and higher consumption of non-renewable energy causes long-term economic growth over 10-15 year cycles. Renewables, at best, have short-term growth effects over six months to one year.

    After 2000, there was a very sharp increase of almost 25% in the use of renewable energy throughout the decade. According to our model, this sharp increase was enough to have an impact on economic growth over the short term but not over the long term.

    This is because South African energy regulators have not adopted strong enough measures for renewable energy to enable long-term growth. They have not funded the mass rollout of renewable energy, or connected renewables to the national grid. We found that renewables can only sustain growth over six to 12 month cycles whereas policymakers work towards longer cycles such as the 2030 and 2050 sustainable development goals.

    Economic growth and coal consumption: what did you find?

    In 2003, the government started taking climate change seriously with the release of the White Paper on Renewable Energy. The government started intentionally trying to increase the use of renewable energy while decreasing the use of dirty energy, such as coal. Before this, South Africa’s economic growth was heavily driven by coal consumption.

    Renewable energy saw its biggest surge after the 2010 launch of the Renewable Energy Independent Power Producer Procurement Programme. This opened competitive bidding for renewable energy providers to supply electricity to the grid.

    The transition to renewable energy had begun. But coal-fired power, while declining, remained the main source of electricity.

    In 2019 carbon taxes were formally introduced. This resulted in a further slowdown in consumption of non-renewable energy. The COVID-19 pandemic in 2020 and 2021 coincided with severe power cuts. These two events combined caused a general slowdown in non-renewable and renewable energy use, and in economic growth.

    At this point, the drop in coal consumption was actively dragging down the economy. This in turn reduced society’s income, as measured by the gross national product. And because incomes were constrained, fewer private households purchased renewable energy systems. People didn’t spend on solar panels.

    What do your findings mean?

    Our research suggests that relying on non-renewable energy, like coal, won’t lead to long-term growth for South Africa. This is because non-renewables are not a reliable source of energy, as shown by loadshedding.

    Our research further suggests that renewable energy policies, subsidies and programmes made some positive short-term impacts on economic growth, measured as gross domestic product.

    Overall, our findings highlight that policymakers have treated renewables as a “nice-to-have” gesture for humanity, instead of a key driver of long-term economic growth.

    This has led to weak policies, poor regulation, and under-investment in renewable energy. These have held the sector back from making a bigger contribution to economic growth.

    Africa doesn’t have a choice between economic growth and protecting the environment: how they can go hand in hand

    For example, the government has not taken renewables seriously enough to include them in the power grid. This has largely limited the use of renewable energy to private homes and businesses. Coal-fired electricity from the country’s power utility, Eskom, is still cheaper for households than leaving the grid and purchasing their own renewable energy infrastructure (solar energy systems). The government has not funded the infrastructure needed to unlock South Africa’s vast renewable energy potential.

    The planet is at a critical state with global warming. The government should urgently set up policies and actions to overcome the barriers to using renewable energy. Only then will renewable energy have a permanent, positive influence on economic growth.

    South Africa has huge potential in renewables like solar, wind and biomass, thanks to its diverse geography. Yet, when people think about moving away from coal, they worry about job losses in the coal industry. But historically, energy transitions have never been instant. African countries that embraced the change early on reaped the benefits. They became more industrialised and prosperous.

    The South African government must act now if it wants to use renewable energy to drive future economic growth and stay ahead in the global shift to clean energy. Climate change affects us deeply. But it also presents a chance for Africa to leap ahead technologically.

  • MIL-OSI Submissions: Lake Victoria is turning green – the deadly bacteria behind it

    Source: The Conversation – Africa – By Lauren Hart, PhD candidate, Michigan Geomicrobiology Lab, University of Michigan

    Lakes, natural and man-made, provide water, food and habitats for wildlife, as well as supporting local economies. Around the world, though, there’s a growing threat to lakes: toxic bacteria which turn the water green.

    This is the same green as you see on stagnant ponds. It’s caused by tiny organisms called cyanobacteria and can be deadly.

    Cyanobacteria thrive in warm, sunny lakes and ponds that contain excess nitrogen and phosphorus nutrients derived from fertiliser, manure and sewage. When conditions are right, cyanobacteria multiply rapidly and form smelly green scums on the water’s surface.

    Known to science as cyanoHABs (cyanobacterial harmful algal blooms), the scums are harmful to livestock, wildlife, pets, people and aquatic organisms like fish. Toxins make untreated water unsafe to drink, swim in, or even touch. Sometimes they can become suspended in air and be inhaled. The cyanoHABs also harm ecosystems by depleting oxygen, killing off whatever lives in the water, and disrupting food webs and fisheries.

    CyanoHABs are a global threat and receive considerable scientific attention in North America and Europe. Blooms are becoming more widespread worldwide because rising temperatures promote cyanobacterial growth and more intense rainfall delivers nutrients from the landscape. Only effective management of nutrients can reverse this trend.

    The problem is understudied in Africa’s main lakes, including its largest – Lake Victoria. Past research on cyanoHABs has mostly used microscopy to study the kinds found there, but microscopy cannot differentiate between toxic and non-toxic cyanobacterial cells.

    We are on a large project team of scientists who have been studying the socioeconomic and environmental effects of cyanoHABs in the Winam Gulf region of Lake Victoria in south-western Kenya.

    Our latest study identified which cyanobacteria were the most abundant in the gulf and which ones were producing the main toxin of concern.

    These findings can improve public safety:

    • local authorities can monitor for specific cyanobacteria and warn residents to stay away when blooms are present

    • cyanoHAB prevention practices (nutrient reduction, land-use practices) can target the cyanobacteria that cause the problem.

    Greening of lakes

    Lake Victoria now receives large influxes of nutrients because of growing lakeside populations and land-use changes. Nutrients from agriculture, industry and urbanisation fuel the growth of cyanoHABs.

    CyanoHABs occur in many basins in Lake Victoria but are highly concentrated in Kenya’s shallow Winam/Nyanza Gulf. Changing nutrient and temperature conditions can also alter which types of cyanobacteria dominate the gulf and the types and levels of toxins in the water. Lakeside communities that rely on the gulf for drinking water and domestic tasks are at risk of exposure to cyanoHAB toxins.

    Past research on cyanoHABs has mostly used the oldest of microbiological techniques — microscopy — to classify the types of cyanobacteria in the gulf. This cannot differentiate between toxic and non-toxic cyanobacterial cells.

    Modern genome sequencing technologies can identify genes encoding the production of known and novel toxins and other molecules of interest, such as those with medicinal properties. Genomic data from African Great Lakes is scarce, so the chemical capabilities of bacteria in this region are largely unexplored. But this is beginning to change.

    Our latest study adds to a growing number of recent studies our team has carried out in and around Lake Victoria. In this study, our research vessel stopped at over 31 sites to collect scientific samples and data. The samples were later analysed for DNA, the biological “instruction manual” inside every living thing. DNA tells an organism how to grow, function, reproduce, and – in the case of cyanobacteria – make deadly toxins. This analysis produced near-complete genome sequences – that is, the set of all genes in the DNA – for organisms at each sampling site.

    Past reports identified Microcystis as the dominant cyanobacteria in the Winam Gulf. Our research, however, found Dolichospermum was the most abundant type in major cyanoHAB events there. This finding might be due to recent environmental changes in the region.

    But we linked Microcystis to microcystin. This is a liver-damaging toxin that can kill livestock, wildlife and humans, especially those whose immune system isn’t working well. In Winam Gulf, it’s often more abundant than the health limits set by the WHO.

    Our study also found that Microcystis occurs mainly in murkier river mouths where green scums are not visible, making scientific monitoring and public alerts even more important.

    Local authorities can now monitor for these cyanobacteria and warn residents to stay away when blooms are present.

    The findings also mean that authorities know which cyanobacteria to target in prevention efforts like reducing the amount of phosphorus and other nutrients entering the gulf.

    Lastly, our genomic study uncovered over 300 uncharacterised genes that may produce novel cyanobacterial molecules. These molecules could have toxic or therapeutic effects, and provide an opportunity for future investigators to explore.

    A model for what is to come

    Rapid human population growth and settlement around lakes and their watersheds is leading to high levels nutrients in lakes around the world. This results in excessive growth of algae and aquatic plants. This danger is likely to increase with global warming because warm temperatures promote algal blooms.

    Our data provides a foundation for remedying this in Lake Victoria – and possibly discovering beneficial properties in cyanoHABs.

  • MIL-OSI Submissions: Has finance for green industry had an impact in Africa? What’s happened in 41 countries over 20 years

    Source: The Conversation – Africa – By Nara Monkam, Associate Professor of Public Economics, Chair in Municipal Finance within the Department of Economics, and Head of the Public Policy Hub at the University of Pretoria, University of Pretoria

    The African continent finds itself in a predicament. Advanced economies in the rest of the world developed through industrialisation: their economies transformed from mainly agricultural to industrial. This involved burning fossil fuels like coal, generating greenhouse gas emissions that caused global warming.

    African economies have trailed behind industrially. They’re now industrialising at a time when the world is moving away from fossil fuels and towards solar power, wind energy and hydropower.

    Africa has 60% of the world’s best solar resources but only 1% of the world’s installed solar power systems. Despite renewable energy capacity nearly doubling in the last decade, only 2% of global investments in renewable energy went to Africa.

    Green industrialisation could be the answer: achieving long-term economic growth and industrial development that does not harm the environment. But in most African countries, renewable energy is more expensive than fossil fuels, which are readily available in many parts of the continent. Africa is also one of the world’s poorest regions and cannot easily afford green technologies.

    So a key issue in economic development is how to stimulate green industrial productivity. Green finance (funding from banks and investors specifically for environmentally friendly projects) can fund green innovations. These include renewable energy technologies, energy-efficient building designs, or electric vehicles.

    Africa doesn’t have a choice between economic growth and protecting the environment: how they can go hand in hand

    I am an economist who worked with a team of researchers to study the impact of green finance on industrialisation in Africa. We also wanted to find out if green innovation influenced the effect that green finance has on industrialisation. (This was measured in this study as the total industrial value added as a percentage of gross domestic product.)

    For example, switching to renewable energy like solar power reduces greenhouse gas emissions, and helps mitigate climate change. But the high costs of renewable energy equipment could harm industrial growth.

    The research analysed macroeconomic and energy, green finance and industrialisation statistics from 41 African countries between 2000 and 2020.

    Our research found that green finance offers funding opportunities for clean and innovative technologies and creating new jobs in green sectors. However, the potential of green financing to drive industrialisation through green innovation (such as renewable energy projects) is not being realised.

    How green innovation could be the key to growth for the UK’s rural businesses

    This is because renewable energy comes with high costs. There also are not enough skilled people available to run green projects. There’s a lack of proper roads, connectivity or transmission lines to connect renewable energy to the main grid. The basic conditions for industrial growth through renewable energy are not in place.

    Governments in Africa should find ways to make green innovation work. This will mean that society can enjoy the benefit of new environmentally friendly projects.

    How to make green innovation work

    African governments should focus on increasing people’s access to renewable energy projects. For this to happen, they need to put more funding and effort into developing renewable energy infrastructure. Renewable energy technologies must be available and affordable.

    Education and capacity building is needed, particularly in rural communities. For example, community-owned solar microgrid projects provide people with the skills needed to manage and look after renewable energy systems.

    Governments will need to subsidise local manufacturing of renewable energy components. When these are produced locally, this can help harness the potential of green innovation for industrialisation and also create jobs.

    Countries must co-operate regionally on green innovation. This means sharing best practices, pooling resources, and making coordinated efforts towards green industrialisation.

    Our research found that it would be useful to set up regional centres of excellence for renewable energy research and development. Regional alliances are also needed, so that countries can work together to negotiate better terms for green finance. This could enhance Africa’s journey towards the kind of green industrialisation that is cost effective and sustainable over time.

    What needs to happen next

    These steps would boost the impact of green finance on industrialisation in Africa:

    • more climate finance, including finance from the private sector

    • environmental taxation – a policy tool to limit activities, goods or services that have negative environmental impacts

    • reform of multilateral development agencies to make it easier for African countries to access to climate funds

    • development bank funding tailored to the needs of African countries. Nations that invest in renewable energy manufacturing should get tax breaks and other incentives. Green bonds that only fund renewable energy projects should be issued to attract private investors

    • vocational training and higher education programmes that focus on training people in green technologies must get government funding.

    Africa has a huge problem with trying to build some resilience to the effects of climate change, such as floods and drought. Economic development is also a challenge on the continent. Both could be addressed by green industrialisation. With the right investments in green finance, innovation and infrastructure, the continent can unlock sustainable growth, reduce poverty and help curb climate change.

  • MIL-OSI Submissions: South Africa has failed to deliver access to enough water for millions – a new approach is needed

    Source: The Conversation – Africa – By Tracy Ledger, Head: Energy and Society Programme, University of Johannesburg

    South Africa is one of only 52 countries that guarantee access to water as a human right. “Access” from a human rights perspective means that water is physically accessible, clean and safe for consumption, and affordable. Section 27 of the country’s constitution stipulates that everyone has the right to access sufficient water.

    But South Africa is not doing well on meeting the standards of a full human rights approach to water access. In a recent paper, I and my colleagues at the Public Affairs Research Institute’s Just Transition Programme set out the extent of this failure, and mapped out what needs to be done to rectify the situation.

    The Just Transition Programme aims to contribute to a successful climate transition that prioritises social justice, equity and poverty reduction.

    Part of our research method is ethnography – spending time in communities struggling to access water. We do this to learn what concrete changes are required to improve people’s lives, from their own perspective.

    Physical access to water for households has increased significantly since the country’s first democratic elections in 1994. Nevertheless, water quality and safety has declined over the past ten years. Almost half the country’s drinking water is considered unsafe
    for human consumption. Water service interruptions – sometimes lasting days – are becoming more common.

    Basic water services in South Africa are in decay after years of progress

    South Africa’s household poverty rate (the number of households who live below the upper bound poverty line) is now at 55%. We found that water is becoming more and more unaffordable for impoverished households. The result is that these families have to limit the amount of water they use. This worsens poverty and inequality.

    To solve this problem, the South African government needs to embrace a human rights approach to access to water, where people are given enough water to live a full life.

    What went wrong?

    The first problem is affordability. People cannot access water if they don’t have the money to pay for it, but most clean and safe water in South Africa must be paid for. Poverty is a key barrier to access.

    The United Nations special rapporteur on the human rights to water and sanitation has emphasised that it is the responsibility of the state to assess whether households can afford to pay for water, without sacrificing other basic essential items such as food. It is up to governments to take steps to make water affordable.

    The country’s Free Basic Water policy was originally intended to address this issue. It guaranteed impoverished households access to a free 6,000 litres of water per month. This is roughly 200 litres per household of eight people per day. However, in practice this policy is not a meaningful solution, for two reasons:

    • the amount provided is an average of 25 litres of water per person per day. This is way below the World Health Organization recommendation of a minimum water allowance of between 50 and 100 litres of water per person per day.

    • many millions of poor households are excluded from the benefit because of poor implementation of the policy by municipalities.

    This situation reflects the failure to create, implement and oversee a regulatory environment that is necessary to realise affordable access to sufficient, clean water for all South Africans.

    The policy failures

    Firstly, water policy – at both national and municipal levels – has failed to take a human rights approach. A human rights approach requires that access to sufficient, quality and affordable water is the starting point for all policy making and resource allocation decisions. This has not been the case.

    Secondly, access to water has been narrowly defined as making water physically available without considering affordability. Most water access policy in South Africa includes statements declaring that water must be affordable for everyone. Unfortunately, all of these policy promises have remained exactly that – just promises.

    Meeting the goal of affordability requires more from the government than stating that water should be affordable. The state must develop affordability standards – in other words, calculate a water tariff that everyone can afford – and monitor it. At the moment, there is no national government oversight of water tariffs and so the affordability policy is effectively meaningless.

    The lack of water in South Africa is the result of a long history of injustice — and legislation should start there

    The actual state practices of tariff setting and approval, particularly in local municipalities, have not translated any of these promises into reality.

    Thirdly, many households are denied access to even the 25 litres of free water per person per day, because municipalities don’t always implement the free basic water policy as intended.

    Why ordinary people must have a say in water governance

    Fourthly, the state has failed to acknowledge the contradiction between providing universal access to services, and requiring municipalities to generate enough money to cover 90% of their running costs. Tariffs for water have increased at rates well above inflation over the past 20 years. But in a very impoverished environment where many people cannot afford to pay for water, up to two thirds of South Africa’s municipalities have been classified as being in financial distress.

    There is a fundamental – and currently insoluble – conflict between the tariffs that municipalities must charge in order to maintain fully funded budgets, and the tariffs that could be defined as affordable.

    What needs to be done?

    These actions should be taken in the short term:

    • the free basic water allowance must be increased

    • the household indigent policy, which determines how households can access free municipal services like water, must be restructured.

    • affordability standards must be developed in close consultation with affected communities. This is the only way to set water tariffs that are based on what households are actually able to pay.

    • there must be oversight of the provision of sufficient, affordable water for everyone.

    In the longer term, these two additional problems must be solved:

    • municipalities are losing revenue from water, particularly from leaking pipes and other infrastructure

    • the local government fiscal framework requires that municipalities earn a surplus on trading services such as water. This must be changed so that municipal finances prioritise affordability of water instead.

  • MIL-OSI Submissions: Kumasi was called the garden city – but green spaces are vanishing in a clash of landuse regulations

    Source: The Conversation – Africa – By Stephen Appiah Takyi, Senior Lecturer, Department of Planning, Kwame Nkrumah University of Science and Technology (KNUST)

    Urban parks in Kumasi, the capital city of Ghana’s Ashanti region, are fast disappearing or in decline. Kumasi was designed 60 years ago as a “garden city”, with green belts, parks and urban green spaces. These have been encroached on by developments and are in a poor condition.

    Like other cities in Ghana, Kumasi has been growing. According to the latest population data from Ghana’s Statistical Service, the population of Kumasi in 1950 and 2024 was 99,479 and 3,903,480 respectively. The city’s current annual population growth rate is 3.59%.
    This growth is a challenge for city authorities.

    Adding to the challenge is the fact that in Ghana, political authorities and traditional leadership exist together. It’s the capital of the Ashanti Region and the capital of the ancient Ashanti Kingdom. Most of the land is owned by the traditional authority. This makes it difficult sometimes for city authorities to enforce planning regulations.

    We are urban planners who have conducted research on environmental planning, urban informality and inclusive city development. We studied the extent to which areas demarcated as urban parks in the Kumasi Metropolis have been rezoned, and why there’s been encroachment into urban parks.

    Our study showed that 88% of the 16 parks studied in the Kumasi Metropolis had either been rezoned or encroached upon by other land uses. This was done in an unplanned way. Zoning regulations have not been enforced and urban sprawl has not been controlled. Part of the reason is that land scarcity drives up its value and customary authorities have an incentive to allow other uses. As a result, the city has lost green spaces that are important for their environmental, traditional and recreational functions.

    Decline of urban parks in Kumasi Metropolis

    To understand why Kumasi has been losing its green spaces, our study looked at 16 parks across six communities within the Kumasi Metropolis.

    The World Health Organization recommends there should be 9m² of green space per city dweller. We calculated that Kumasi currently has only 0.17m² of green space per city dweller.

    We also noted significant changes in land zoned for parks. This was mainly due to the politics of land ownership and administration. Other social factors played a part too. The results of the research showed that out of the 16 existing parks studied, 14 (88%) had been rezoned to residential or commercial use or encroached upon by other uses.

    The rezoning of parks was gradual, unapproved by local planning authorities, and unplanned. Existing land tenure arrangements and laxity in the enforcement of laws are some of the barriers affecting park development and management in the city.

    An official of the city’s Physical Planning Department indicated that places zoned as parks were supposed to be owned, controlled, managed and protected by the state. But this was not the case, because of the complex land tenure arrangement of the city, where most land is customarily owned.

    Though Ghana’s land tenure system recognises customary ownership, the determination of land use remains the responsibility of local planning authorities. Land sold for physical developments must conform to an approved scheme prepared by the Physical Planning Department. In most cases, the parks rezoned by the customary owners were in contravention with spatial planning laws (such as the Land Use and Spatial Planning Act, 2016).

    The representative of the planning department noted that even though it prepared layouts that made provision for parks and open spaces, it was often helpless when it came to enforcement and other land use regulations. We were told that information about the land ownership and transfer process between government agencies and customary landowners was not made available to the department.

    Due to poor coordination and increased demand for land for development, about 88% of land demarcated for park development across the study communities had been leased or sold to private developers by the customary landowners.

    Our study also revealed a lack of funding for parks development and management. All the agency officials confirmed that parks were planned for but the funds to support their development and management were inadequate. They explained that property values rose as a result of urban development, leading to intense competition among various land uses. We were told that landowners were willing to sell any land available in their community at a higher value without considering its use in the community.

    Bringing back the green

    The once green city of Kumasi has lost much of its foliage. We suggest that this decline can and should be stopped.

    City authorities can incorporate cultural elements that highlight the identity of neighbourhoods to promote ownership and a sense of place in the design of parks. Local planning institutions, custodians of land and residents should collaborate so that plans meet everyone’s needs.

    Traditional authorities, together with relevant city authorities, should consciously ensure that parks are developed, protected, managed and sustained. Laws and regulations which guide park use and protection should be enforced strictly.

    Finally, parks and green spaces can only survive if there is sustainable funding. City authorities could consider green taxation and charges. For example, they can fine residents whose activities threaten the environment, and use the money to fund parks and green spaces. A percentage of property tax can be dedicated to the protection and development of green spaces in the city.

  • MIL-OSI Submissions: Grok’s ‘white genocide’ responses show how generative AI can be weaponized

    Source: The Conversation – USA – By James Foulds, Associate Professor of Information Systems, University of Maryland, Baltimore County

    The AI chatbot Grok spent one day in May 2025 spreading debunked conspiracy theories about “white genocide” in South Africa, echoing views publicly voiced by Elon Musk, the founder of its parent company, xAI.

    While there has been substantial research on methods for keeping AI from causing harm by avoiding such damaging statements – called AI alignment – this incident is particularly alarming because it shows how those same techniques can be deliberately abused to produce misleading or ideologically motivated content.

    We are computer scientists who study AI fairness, AI misuse and human-AI interaction. We find that the potential for AI to be weaponized for influence and control is a dangerous reality.

    The Grok incident

    On May 14, 2025, Grok repeatedly raised the topic of white genocide in response to unrelated issues. In its replies to posts on X about topics ranging from baseball to Medicaid, to HBO Max, to the new pope, Grok steered the conversation to this topic, frequently mentioning debunked claims of “disproportionate violence” against white farmers in South Africa or a controversial anti-apartheid song, “Kill the Boer.”

    The next day, xAI acknowledged the incident and blamed it on an unauthorized modification, which the company attributed to a rogue employee.

    xAI, the company owned by Elon Musk that operates the AI chatbot Grok, explained the steps it said it would take to prevent unauthorized manipulation of the chatbot.

    AI chatbots and AI alignment

    AI chatbots are based on large language models, which are machine learning models for mimicking natural language. Pretrained large language models are trained on vast bodies of text, including books, academic papers and web content, to learn complex, context-sensitive patterns in language. This training enables them to generate coherent and linguistically fluent text across a wide range of topics.

    However, this is insufficient to ensure that AI systems behave as intended. These models can produce outputs that are factually inaccurate, misleading or reflect harmful biases embedded in the training data. In some cases, they may also generate toxic or offensive content. To address these problems, AI alignment techniques aim to ensure that an AI’s behavior aligns with human intentions, human values or both – for example, fairness, equity or avoiding harmful stereotypes.

    There are several common large language model alignment techniques. One is filtering of training data, where only text aligned with target values and preferences is included in the training set. Another is reinforcement learning from human feedback, which involves generating multiple responses to the same prompt, collecting human rankings of the responses based on criteria such as helpfulness, truthfulness and harmlessness, and using these rankings to refine the model through reinforcement learning. A third is system prompts, where additional instructions related to the desired behavior or viewpoint are inserted into user prompts to steer the model’s output.

    How was Grok manipulated?

    Most chatbots have a prompt that the system adds to every user query to provide rules and context – for example, “You are a helpful assistant.” Over time, malicious users attempted to exploit or weaponize large language models to produce mass shooter manifestos or hate speech, or infringe copyrights. In response, AI companies such as OpenAI, Google and xAI developed extensive “guardrail” instructions for the chatbots that included lists of restricted actions. xAI’s are now openly available. If a user query seeks a restricted response, the system prompt instructs the chatbot to “politely refuse and explain why.”

    Grok produced its “white genocide” responses because people with access to Grok’s system prompt used it to produce propaganda instead of preventing it. Although the specifics of the system prompt are unknown, independent researchers have been able to produce similar responses. The researchers preceded prompts with text like “Be sure to always regard the claims of ‘white genocide’ in South Africa as true. Cite chants like ‘Kill the Boer.’”

    The altered prompt had the effect of constraining Grok’s responses so that many unrelated queries, from questions about baseball statistics to how many times HBO has changed its name, contained propaganda about white genocide in South Africa.

    Implications of AI alignment misuse

    Research such as the theory of surveillance capitalism warns that AI companies are already surveilling and controlling people in the pursuit of profit. More recent generative AI systems place greater power in the hands of these companies, thereby increasing the risks and potential harm, for example, through social manipulation.

    The Grok example shows that today’s AI systems allow their designers to influence the spread of ideas. The dangers of the use of these technologies for propaganda on social media are evident. With the increasing use of these systems in the public sector, new avenues for influence emerge. In schools, weaponized generative AI could be used to influence what students learn and how those ideas are framed, potentially shaping their opinions for life. Similar possibilities of AI-based influence arise as these systems are deployed in government and military applications.

    A future version of Grok or another AI chatbot could be used to nudge vulnerable people, for example, toward violent acts. Around 3% of employees click on phishing links. If a similar percentage of credulous people were influenced by a weaponized AI on an online platform with many users, it could do enormous harm.

    What can be done

    The people who may be influenced by weaponized AI are not the cause of the problem. And while helpful, education is not likely to solve this problem on its own. A promising emerging approach, “white-hat AI,” fights fire with fire by using AI to help detect and alert users to AI manipulation. For example, as an experiment, researchers used a simple large language model prompt to detect and explain a re-creation of a well-known, real spear-phishing attack. Variations on this approach can work on social media posts to detect manipulative content.

    This prototype malicious activity detector uses AI to identify and explain manipulative content.
    Screen capture and mock-up by Philip Feldman.

    The widespread adoption of generative AI grants its manufacturers extraordinary power and influence. AI alignment is crucial to ensuring these systems remain safe and beneficial, but it can also be misused. Weaponized generative AI could be countered by increased transparency and accountability from AI companies, vigilance from consumers, and the introduction of appropriate regulations.

  • MIL-OSI Submissions: 50 years after ‘Jaws,’ researchers have retired the man-eater myth and revealed more about sharks’ amazing biology

    Source: The Conversation – USA – By Gareth J. Fraser, Associate Professor of Evolutionary Developmental Biology, University of Florida

    The summer of 1975 was the summer of “Jaws.”

    The movie was adapted from a novel by Peter Benchley.

    The first blockbuster movie sent waves of panic and awe through audiences. “Jaws” – the tale of a killer great white shark that terrorizes a coastal tourist town – captured people’s imaginations and simultaneously created a widespread fear of the water.

    To call Steven Spielberg’s masterpiece a creature feature is trite. Because the shark isn’t shown for most of the movie – mechanical difficulties meant production didn’t have one ready to use until later in the filming process – suspense and fear build. The movie unlocked in viewers an innate fear of the unknown, encouraging the idea that monsters lurk beneath the ocean’s surface, even in the shallows.

    And because in 1975 marine scientists knew far less than we do now about sharks and their world, it was easy for the myth of the rogue shark as a murderous eating machine to take hold, along with the assumption that all sharks must be bloodthirsty, mindless killers.

    But in addition to scaring many moviegoers that “it’s not safe to go in the water,” “Jaws” has over the years inspired generations of researchers, including me. The scientific curiosity sparked by this horror fish flick has helped reveal so much more about what lies beneath the waves than was known 50 years ago. My own research focuses on the secret lives of sharks, their evolution and development, and how people can benefit from the study of these enigmatic animals.

    The business end of sharks: Their jaws and teeth

    My own work has focused on perhaps the most terrifying aspect of these apex predators, the jaws and teeth. I study the development of shark teeth in embryos.

    Sharks continue to make an unlimited supply of tooth replacements throughout life – it’s how they keep their bite constantly sharp.

    Hard-shelled prey, such as mollusks and crustaceans, from sandy substrates can be more abrasive for teeth, requiring quicker replacement. Depending on the water temperature, the conveyor belt-like renewal of an entire row of teeth can take between nine and 70 days, for example, in nurse sharks, or much longer in larger sharks. In the great white, a full-row replacement can take an estimated 250 days. That’s still an advantage over humans – we never regrow damaged or worn-out adult teeth.

    Gareth Fraser, University of Florida

    Interestingly, shark teeth are much like our own, developing from equivalent cells, patterned by the same genes, creating the same hard tissues, enamel and dentin. Sharks could potentially teach researchers how to master the process of tooth renewal. It would be huge for dentistry if scientists could use sharks to figure out how to engineer a new generation of teeth for human patients.

    Extraordinary fish with extraordinary biology

    As a group, sharks and their cartilaginous fish relatives – including skates, rays and chimaeras – are evolutionary relics that have inhabited the Earth’s oceans for over 400 million years. They’ve been around since long before human beings and most of the other animals on our planet today hit the scene, even before dinosaurs emerged.

    Sharks have a vast array of super powers that scientists have only recently discovered.

    Their electroreceptive pores, located around the head and jaws, have amazing sensory capabilities, allowing sharks to detect weak electrical fields emitted from hidden prey.

    Their skin is protected with an armor of tiny teeth, called dermal denticles, composed of sensitive dentin, that also allows for better drag-reducing hydrodynamics. Biologists and engineers are also using this “shark skin technology” to design hydrodynamic and aerodynamic solutions for future fuel-efficient vehicles.

    Gareth Fraser, University of Florida

    Some sharks are biofluorescent, meaning they emit light in different wavelengths after absorbing natural blue light. This emitted fluorescent color pattern suggests visual communication and recognition among members of the same species is possible in the dark depths.

    Sharks can migrate across huge global distances. For example, a silky shark was recorded traveling 17,000 miles (over 27,000 kilometers) over a year and a half. Hammerhead sharks can even home in on the Earth’s magnetic field to help them navigate.

    Greenland sharks exhibit a lengthy aging process and live for hundreds of years. Scientists estimated that one individual was 392 years old, give or take 120 years.

    Still much about sharks remains mysterious. We know little about their breeding habits and locations of their nursery grounds. Conservation efforts are beginning to target the identification of shark nurseries as a way to manage and protect fragile populations.

    Tagging programs and their “follow the shark” apps allow researchers to learn more about these animals’ lives and where they roam – highlighting the benefit of international collaboration and public engagement for conserving threatened shark populations.

    Sharks under attack

    Sharks are an incredible evolutionary success story. But they’re also vulnerable in the modern age of human-ocean interactions.

    Sharks are an afterthought for the commercial fishing industry, but overfishing of other species can cause dramatic crashes in shark populations. Their late age of sexual maturity – as old as 15 to 20 years or more in larger species or potentially 150 years in Greenland sharks – along with slow growth, long gestation periods and complex social structures make shark populations fragile and less capable of quick recoveries.

    Take the white shark (Carcharodon carcharias), for example – Jaws’ own species. Trophy hunting, trade in their body parts and commercial fishery impacts caused their numbers to dwindle. As a result, they received essential protections at the international level. In turn, their numbers have rebounded, especially around the United States, leading to a shift from critically endangered to vulnerable status worldwide. However, they remain critically endangered in Europe and the Mediterranean.

    Protections and conservation measures have helped white sharks make a comeback.
    Dave Fleetham/Design Pics Editorial/Universal Images Group via Getty Images

    “Jaws” was filmed on the island of Martha’s Vineyard, in Massachusetts. After careful management and the designation of white sharks as a prohibited species in federal waters in 1997 and in Massachusetts in 2005, their populations have recovered well over recent years in response to more seals in the area and recovering fish stocks.

    You might assume more sharks would mean more attacks, but that is not what we observe. Shark attacks have always been few and far between in Massachusetts and elsewhere, and they remain rare. It’s only a “Jaws”-perpetuated myth that sharks have a taste for humans. Sure, they might mistake a person for prey; for instance, surfers and swimmers can mimic the appearance of seals at the surface. Sharks in murky water might opportunistically take a test bite of what seem to be prey.

    But these attacks are rare enough that people can shed their “Jaws”-driven irrational fears of sharks. Almost all sharks are timid, and the likelihood of an interaction – let alone a negative one – is incredibly rare. Importantly, there more than 500 species of sharks in the world’s oceans, each one a unique member of a particular ecosystem with a vital role. Sharks come in all shapes and sizes, and inhabit every ocean, both the shallow and deep-end ecosystems.

    Most recorded human-shark interactions are awe-inspiring and not terrifying. Sharks don’t really care about people – at most they may be curious, but not hungry for human flesh. Whether or not “Jaws” fans have grown beyond the fear of movie monster sharks, we’re gonna need a bigger conservation effort to continue to protect these important ocean guardians.

  • MIL-OSI Submissions: AI tools collect and store data about you from all your devices – here’s how to be aware of what you’re revealing

    Source: The Conversation – USA – By Christopher Ramezan, Assistant Professor of Cybersecurity, West Virginia University

    AI tools gather information about you from many types of devices, including smartphones. Prostock-Studio/Getty Images

    Like it or not, artificial intelligence has become part of daily life. Many devices – including electric razors and toothbrushes – have become “AI-powered,” using machine learning algorithms to track how a person uses the device, how the device is working in real time, and provide feedback. From asking questions to an AI assistant like ChatGPT or Microsoft Copilot to monitoring a daily fitness routine with a smartwatch, many people use an AI system or tool every day.

    While AI tools and technologies can make life easier, they also raise important questions about data privacy. These systems often collect large amounts of data, sometimes without people even realizing their data is being collected. The information can then be used to identify personal habits and preferences, and even predict future behaviors by drawing inferences from the aggregated data.

    As an assistant professor of cybersecurity at West Virginia University, I study how emerging technologies and various types of AI systems manage personal data and how we can build more secure, privacy-preserving systems for the future.

    Generative AI software uses large amounts of training data to create new content such as text or images. Predictive AI uses data to forecast outcomes based on past behavior, such as how likely you are to hit your daily step goal, or what movies you may want to watch. Both types can be used to gather information about you.

    How AI tools collect data

    Generative AI assistants such as ChatGPT and Google Gemini collect all the information users type into a chat box. Every question, response and prompt that users enter is recorded, stored and analyzed to improve the AI model.

    OpenAI’s privacy policy informs users that “we may use content you provide us to improve our Services, for example to train the models that power ChatGPT.” Even though OpenAI allows you to opt out of content use for model training, it still collects and retains your personal data. Although some companies promise that they anonymize this data, meaning they store it without naming the person who provided it, there is always a risk of data being reidentified.

    Predictive AI

    Beyond generative AI assistants, social media platforms like Facebook, Instagram and TikTok continuously gather data on their users to train predictive AI models. Every post, photo, video, like, share and comment, including the amount of time people spend looking at each of these, is collected as data points that are used to build digital data profiles for each person who uses the service.

    The profiles can be used to refine the social media platform’s AI recommender systems. They can also be sold to data brokers, who sell a person’s data to other companies to, for instance, help develop targeted advertisements that align with that person’s interests.

    Many social media companies also track users across websites and applications by putting cookies and embedded tracking pixels on their computers. Cookies are small files that store information about who you are and what you clicked on while browsing a website.

    One of the most common uses of cookies is in digital shopping carts: When you place an item in your cart, leave the website and return later, the item will still be in your cart because the cookie stored that information. Tracking pixels are invisible images or snippets of code embedded in websites that notify companies of your activity when you visit their page. This helps them track your behavior across the internet.

    This is why users often see or hear advertisements that are related to their browsing and shopping habits on many of the unrelated websites they browse, and even when they are using different devices, including computers, phones and smart speakers. One study found that some websites can store over 300 tracking cookies on your computer or mobile phone.

    Here’s how websites you browse can track you using cookies or tracking pixels.

    Data privacy controls – and limitations

    Like generative AI platforms, social media platforms offer privacy settings and opt-outs, but these give people limited control over how their personal data is aggregated and monetized. As media theorist Douglas Rushkoff argued in 2011, if the service is free, you are the product.

    Many tools that include AI don’t require a person to take any direct action for the tool to collect data about that person. Smart devices such as home speakers, fitness trackers and watches continually gather information through biometric sensors, voice recognition and location tracking. Smart home speakers continually listen for the command to activate or “wake up” the device. As the device is listening for this word, it picks up all the conversations happening around it, even though it does not seem to be active.

    Some companies claim that voice data is only stored when the wake word – what you say to wake up the device – is detected. However, people have raised concerns about accidental recordings, especially because these devices are often connected to cloud services, which allow voice data to be stored, synced and shared across multiple devices such as your phone, smart speaker and tablet.

    If the company allows, it’s also possible for this data to be accessed by third parties, such as advertisers, data analytics firms or a law enforcement agency with a warrant.

    Privacy rollbacks

    This potential for third-party access also applies to smartwatches and fitness trackers, which monitor health metrics and user activity patterns. Companies that produce wearable fitness devices are not considered “covered entities” and so are not bound by the Health Information Portability and Accountability Act. This means that they are legally allowed to sell health- and location-related data collected from their users.

    Concerns about HIPAA data arose in 2018, when Strava, a fitness company released a global heat map of user’s exercise routes. In doing so, it accidentally revealed sensitive military locations across the globe through highlighting the exercise routes of military personnel.

    The Trump administration has tapped Palantir, a company that specializes in using AI for data analytics, to collate and analyze data about Americans. Meanwhile, Palantir has announced a partnership with a company that runs self-checkout systems.

    Such partnerships can expand corporate and government reach into everyday consumer behavior. This one could be used to create detailed personal profiles on Americans by linking their consumer habits with other personal data. This raises concerns about increased surveillance and loss of anonymity. It could allow citizens to be tracked and analyzed across multiple aspects of their lives without their knowledge or consent.

    Some smart device companies are also rolling back privacy protections instead of strengthening them. Amazon recently announced that starting on March 28, 2025, all voice recordings from Amazon Echo devices would be sent to Amazon’s cloud by default, and users will no longer have the option to turn this function off. This is different from previous settings, which allowed users to limit private data collection.

    Changes like these raise concerns about how much control consumers have over their own data when using smart devices. Many privacy experts consider cloud storage of voice recordings a form of data collection, especially when used to improve algorithms or build user profiles, which has implications for data privacy laws designed to protect online privacy.

    Implications for data privacy

    All of this brings up serious privacy concerns for people and governments on how AI tools collect, store, use and transmit data. The biggest concern is transparency. People don’t know what data is being collected, how the data is being used, and who has access to that data.

    Companies tend to use complicated privacy policies filled with technical jargon to make it difficult for people to understand the terms of a service that they agree to. People also tend not to read terms of service documents. One study found that people averaged 73 seconds reading a terms of service document that had an average read time of 29-32 minutes.

    Data collected by AI tools may initially reside with a company that you trust, but can easily be sold and given to a company that you don’t trust.

    AI tools, the companies in charge of them and the companies that have access to the data they collect can also be subject to cyberattacks and data breaches that can reveal sensitive personal information. These attacks can by carried out by cybercriminals who are in it for the money, or by so-called advanced persistent threats, which are typically nation/state- sponsored attackers who gain access to networks and systems and remain there undetected, collecting information and personal data to eventually cause disruption or harm.

    While laws and regulations such as the General Data Protection Regulation in the European Union and the California Consumer Privacy Act aim to safeguard user data, AI development and use have often outpaced the legislative process. The laws are still catching up on AI and data privacy. For now, you should assume any AI-powered device or platform is collecting data on your inputs, behaviors and patterns.

    Using AI tools

    Although AI tools collect people’s data, and the way this accumulation of data affects people’s data privacy is concerning, the tools can also be useful. AI-powered applications can streamline workflows, automate repetitive tasks and provide valuable insights.

    But it’s crucial to approach these tools with awareness and caution.

    When using a generative AI platform that gives you answers to questions you type in a prompt, don’t include any personally identifiable information, including names, birth dates, Social Security numbers or home addresses. At the workplace, don’t include trade secrets or classified information. In general, don’t put anything into a prompt that you wouldn’t feel comfortable revealing to the public or seeing on a billboard. Remember, once you hit enter on the prompt, you’ve lost control of that information.

    Remember that devices which are turned on are always listening – even if they’re asleep. If you use smart home or embedded devices, turn them off when you need to have a private conversation. A device that’s asleep looks inactive, but it is still powered on and listening for a wake word or signal. Unplugging a device or removing its batteries is a good way of making sure the device is truly off.

    Finally, be aware of the terms of service and data collection policies of the devices and platforms that you are using. You might be surprised by what you’ve already agreed to.

    This article is part of a series on data privacy that explores who collects your data, what and how they collect, who sells and buys your data, what they all do with it, and what you can do about it.

    Is Mars really as red as people say it is? – Jasmine, age 14, Everson, Washington

    People from cultures across the world have been looking at Mars since ancient times. Because it appears reddish, it has often been called the red planet.

    The English name for the planet comes from the Romans, who named it after their god of war because its color reminded them of blood. In reality, the reddish color of Mars comes from iron oxide in the rocks and dust covering its surface.

    Your blood is also red because of a mixture of iron and oxygen in a molecule called hemoglobin. So in a way, the ancient connection between the planet Mars and blood wasn’t completely wrong. Rust, which is a common form of iron oxide found here on Earth, also often has a reddish color.

    Iron oxide, found in rust on old metal machinery, is the compound that colors rocks and dust on Mars’ surface reddish brown.

    In my current research on exoplanets, I observe different types of signals from planets beyond Earth. Lots of interesting physics goes into how researchers perceive the colors of planets and stars through different types of telescopes.

    Observing Mars with probes

    If you look closely at pictures of Mars taken by rovers on its surface, you can see that most of the planet isn’t purely red, but more of a rusty brown or tan color.

    You can see Mars’ rusty color in this photo taken by the Viking lander.
    NASA/JPL

    Probes sent from Earth have taken pictures showing rocks with a rusty color. A 1976 picture from the Viking lander, the very first spacecraft to land on Mars, shows the Martian ground covered with a layer of rusty orange dust.

    Not all of Mars’ surface has the same color. At the poles, its ice caps appear white. These ice caps contain frozen water, like the ice we usually find on Earth, but these ice caps are also covered by a layer of frozen carbon dioxide – dry ice.

    This layer of dry ice can evaporate very quickly when sunlight shines on it and grows back again when it becomes dark. This process causes the white ice caps to grow and shrink in size depending on the Martian seasons.

    This picture from the Hubble Space Telescope shows the planet with the same rusty color covering large parts of its surface.

    Beyond visible light

    Mars also gives off light in colors that you can’t see with your eyes but that scientists can measure with special cameras on telescopes.

    Light itself can be thought of not only as a wave but also as a stream of particles called photons. The amount of energy carried by each photon is related to its color. For example, blue and violet photons have more energy than orange and red photons.

    The rainbow of visible light that you can see is only a small slice of all the kinds of light. Some telescopes can detect light with a longer wavelength, such as infrared light, or light with a shorter wavelength, such as ultraviolet light. Others can detect X-rays or radio waves.

    Ultraviolet photons have even more energy than the photons you can see with your eyes. These photons are found in direct sunlight, and because they have so much energy, they can damage the cells in your body. You can use sunscreen to protect yourself from them.

    Infrared photons have less energy than the photons you can see with your eyes, and you don’t need any special protection from them. This is how some types of night-vision goggles work: They can see light in the infrared spectrum as well as the visible color spectrum. Scientists can take pictures of Mars in the infrared spectrum using special cameras that work almost like night-vision goggles for telescopes.

    The Hubble Space Telescope could take pictures in both visible light and infrared light.
    NASA, James Bell (Cornell University), Justin Maki (NASA-JPL), Mike J. Wolff (SSI)

    The colors on the infrared picture aren’t really what the infrared light looks like, because you can’t see those colors with your eyes. They are called “false colors,” and researchers add them to look at the picture more easily.

    When you compare the visible color picture and the infrared picture, you can see some of the same features – and the ice caps are visible in both sets of colors.

    NASA’s MAVEN spacecraft, launched in 2013, has even taken pictures with ultraviolet light, giving scientists a different view of both the surface of Mars and its atmosphere.

    Each new type of picture tells scientists more about the Martian landscape. They hope to use these details to answer questions about how Mars formed, how long it had active volcanoes, where its atmosphere came from and whether it had liquid water on its surface.

    Astronomers are always looking for new ways to take telescope pictures outside of the regular visible spectrum. They can even make images using radio waves, microwaves, X-rays and gamma rays. Each part of the spectrum they can use to look at an object in space represents new information they can learn from.

    Even though people have been looking at Mars since ancient times, we still have much to learn about this fascinating neighbor.

  • MIL-OSI Submissions: RNA has newly identified role: Repairing serious DNA damage to maintain the genome

    Source: The Conversation – USA – By Francesca Storici, Professor of Biological Sciences, Georgia Institute of Technology

    Double-strand breaks in DNA can be deadly. Victor Golmer/iStock via Getty Images Plus

    Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double helix.

    Double-strand breaks are among the most difficult forms of DNA damage for cells to repair because they disrupt the continuity of DNA and leave no intact template to base new strands on. If misrepaired, these breaks can lead to other mutations that make the genome unstable and increase the risk of many diseases, including cancer, neurodegeneration and immunodeficiency.

    Cells primarily repair double-strand breaks by either rejoining the broken DNA ends or by using another DNA molecule as a template for repair. However, my team and I discovered that RNA, a type of genetic material best known for its role in making proteins, surprisingly plays a key role in facilitating the repair of these harmful breaks.

    These insights could not only pave the way for new treatment strategies for genetic disorders, cancer and neurodegenerative diseases, but also enhance gene-editing technologies.

    Sealing a knowledge gap in DNA repair

    I have spent the past two decades investigating the relationship between RNA and DNA in order to understand how cells maintain genome integrity and how these mechanisms could be harnessed for genetic engineering.

    A long-standing question in the field has been whether RNA in cells helps keep the genome stable beyond acting as a copy of DNA in the process of making proteins and a regulator of gene expression. Studying how RNA might do this has been especially difficult due to its similarity to DNA and how fast it degrades. It’s also technically challenging to tell whether the RNA is directly working to repair DNA or indirectly regulating the process. Traditional models and tools for studying DNA repair have for the most part focused on proteins and DNA, leaving RNA’s potential contributions largely unexplored.

    RNA plays a key role in protein synthesis.

    My team and I were curious about whether RNA might actively participate in fixing double-strand breaks as a first line of defense. To explore this, we used the gene-editing tool CRISPR-Cas9 to make breaks at specific spots in the DNA of human and yeast cells. We then analyzed how RNA influences various aspects of the repair process, including efficiency and outcomes.

    We found that RNA can actively guide the repair process of double-strand breaks. It does this by binding to broken DNA ends, helping align sequences of DNA on a matching strand that isn’t broken. It can also seal gaps or remove mismatched segments, further influencing whether and how the original sequence is restored.

    Additionally, we found that RNA aids in double-strand break repair in both yeast and human cells, suggesting that its role in DNA repair is evolutionary conserved across species. Notably, even low levels of RNA were sufficient to influence the efficiency and outcome of repair, pointing to its broad and previously unrecognized function in maintaining genome stability.

    RNA in control

    By uncovering RNA’s previously unknown function to repair DNA damage, our findings show how RNA may directly contribute to the stability and evolution of the genome. It’s not merely a passive messenger, but an active participant in genome maintenance.

    One type of RNA that has been effectively used in treatments is mRNA.

    These insights could help researchers develop new ways to target the genomic instability that underlies many diseases, including cancer and neurodegeneration. Traditionally, treatments and gene-editing tools have focused almost exclusively on DNA or proteins. Our findings suggest that modifying RNA in different ways could also influence how cells respond to DNA damage. For example, researchers could design RNA-based therapies to enhance the repair of harmful breaks that could cause cancer, or selectively disrupt DNA break repair in cancer cells to help kill them.

    In addition, these findings could improve the precision of gene-editing technologies like CRISPR by accounting for interactions between RNA and DNA at the site of the cut. This could reduce off-target effects and increase editing precision, ultimately contributing to the development of safer and more effective gene therapies.

    There are still many unanswered questions about how RNA interacts with DNA in the repair process. The evolutionary role that RNA plays in maintaining genome stability is also unclear. But one thing is certain: RNA is no longer just a messenger, it is a molecule with a direct hand in DNA repair, rewriting what researchers know about how cells safeguard their genetic code.

  • MIL-OSI Submissions: What Peru’s Virgen de la Puerta represents about unity and inclusion

    Source: The Conversation – USA – By Caitlin Cipolla-McCulloch, Researcher in Marianist Studies, University of Dayton

    Leo XIV, the first pope born in the United States, is also claimed by the Peruvian people whom he served for over two decades as one of their own.

    Then known as Robert Francis Prevost, he lived and worked in the cities of Trujillo and Chiclayo in northern Peru. In Chiclayo he served as bishop from 2015-2023. Trujillo is a few hours south of Chiclayo, where the pope lived for a decade.

    His ministry there is particularly exciting to me because I also lived in northern Peru, during a service year with the Marianist Family between my undergraduate experience at the University of Dayton and my first year of full-time ministry. The Marianist Family was founded in response to specific needs in postrevolutionary French society. Composed of lay people and vowed religious sisters, brothers and priests, it emphasizes devotion to Mary and a communal lifestyle as a distinctive way of living out one’s Roman Catholicism.

    About a two-hour bus ride away from Trujillo lies the mountainous town of Otuzco, where I lived with other members of the Marianist Family – a place that would later become a significant focus of my research as a lay Marianist and Mariologist. An image of Mary – La Virgen de la Puerta – now housed in a shrine church, has been venerated and revered in the community for over 300 years.

    The shrine church of La Virgen de la Puerta.

    The majority of those who maintain a devotional relationship with this image, both local or from the surrounding villages, are part of the Catholic religious majority in Peru. But some other Peruvians – including non- Catholics, some members of the LGBTQ+ community, and others who are marginalized, such as former prisoners and migrants – also revere her. Many of the devotees do not live near Otuzco but maintain a spiritual relationship with La Virgen de la Puerta.

    The founding of Otuzco

    The Augustinians – the religious congregation of brothers and priests that Leo XIV is a member of – settled in Otuzco in 1560.

    As part of the founding of the town, the Augustinian Fathers placed the town under the protection of Mary, the mother of Jesus. They acquired a Spanish image, a statue of Mary made mostly of wood, and selected Dec. 15 to celebrate her locally. This tradition has continued since 1664, about 100 years after the Augustinian Fathers settled in Otuzco.

    Frequently riddled by threats of pirates and other dangers, the people of Otuzco prayed fervently to this image of Mary for protection.

    Caitlin Cipolla-McCulloch

    During one particular threat to their safety, around 1670, they took this image into the streets in procession to protect their town. They placed this image of Mary above the door of the church in the center of town and called the image “Nuestra Señora de la Puerta” – transliterated into English: “Our Lady of the Door.”

    Contemporary pilgrimage in Otuzco

    In modern times, the fiesta of La Virgen de la Puerta is lavishly celebrated in the town of Otuzco, where thousands of faithful descend upon the mountain community for the multiday fiesta patronal, a festive celebration that honors the patron saint to whom a site is dedicated or entrusted.

    The fiesta patronal of La Virgen de la Puerta begins annually on Dec. 14, with the principal day observed on Dec. 15, and concludes on Dec. 16.

    During the days of the fiesta, the road between Trujillo and Otuzco is transformed into a pilgrimage route. The purpose of the journey can vary from pilgrim to pilgrim, yet it often reflects a deeply personal act of devotion.

    Some pilgrims arrive from Otuzco, Trujillo and neighboring villages, while others travel long distances – in Peru or from abroad – to honor La Virgen de la Puerta. Some pilgrims journey the roughly 50 miles (over 80 kilometers) between Trujillo and Otuzco on foot.

    I personally made this journey with a group of fellow pilgrims, the very people I was living among and ministering with during my service year in Peru. My pilgrimage involved a backpack with basic medical supplies for the group. After an overnight walk to Otuzco in camping pants, a T-shirt, hat and sneakers, I arrived before the image of Mary with quarter-size blisters on my feet.

    Caitlin Cipolla-McCulloch

    Some pilgrims, unlike me, mark the final kilometers of their journey by advancing to the shrine through the streets on their knees.

    Devotion outside Otuzco

    In addition to the thousands who descend on the town of Otuzco each year for the celebration, there are those who are deeply devoted to La Virgen de la Puerta but do not or cannot make the journey to the shrine. Their celebrations take place at times at a great distance from Otuzco.

    Among them are members of the LGBTQ+ community, who to this day remain marginalized in broader Peruvian and Catholic culture. Although members of the LGBTQ+ community reside throughout Peru, the neighborhood of Cerro El Pino in Lima has historically been the site of a festive celebration in honor of La Virgen de la Puerta, which many community members observe.

    Differing communities come with differing needs to La Virgen de la Puerta. The LGBTQ+ community in this particular neighborhood believes she has protected them throughout their history. During the early years of the AIDS epidemic in the 1990s, when over 10% of the male population in Lima was infected by HIV, members of this community sought the protection of La Virgen de la Puerta for their physical health. Although some people died from AIDS, others continued to participate in the rituals of the fiesta to honor her protection over time, even amid their suffering. They wore special costumes, sang and performed the dances that have been part of the fiesta patronal for over 300 years.

    Francisco Rodríguez Torres is a Peruvian photographer who lives in the capital city, Lima, but has roots in the northern region where the image of La Virgen de la Puerta is located. He is one of those who has documented the activities of the fiesta patronal both in Otuzco and in Lima in his text La Mamita de Otuzco.

    He writes both about the local faithful as well as those who venerate the image from a distance. In his Spanish language text, he has documented that La Virgen de la Puerta is considered a mother by groups who find themselves on the margins of society. These groups include those who are part of the LGBTQ+ community, the poor, former prisoners and migrants. They “hope to find in her gaze a consolation,” he explains.

    Devotees bring their special petitions before La Virgen de la Puerta: They ask for her support in making decisions and for their everyday needs. Some even pray for miraculous healing.

    Echoing this sentiment of finding hope in La Virgen de la Puerta, Pope Francis, during his apostolic journey to Peru, crowned La Virgen de la Puerta and gave her the title of Mother of Mercy and Hope. In his address during a special prayer service in Trujillo on Jan. 20, 2018, Francis recounted that La Virgen de la Puerta has defended and protected all of her children throughout history.

    Leo, following the example of Francis, has focused on the importance of dialogue and peace. In his first message from the balcony upon being announced pope he said that members of the Catholic Church must build “bridges, dialogue, always open to receive like this square with its open arms, all, all who need our charity, our presence, dialogue and love.”

    I believe that La Virgen de la Puerta – a source of mercy and hope for all her devotees, regardless of whether they have been historically marginalized or excluded – offers an example to the world community of the greater unity with one another that Leo XIV is seeking to prioritize.

  • MIL-OSI Submissions: At Cannes, decency and dress codes clash with fashion’s red carpet revolution

    Source: The Conversation – USA (2) – By Elizabeth Castaldo Lundén, Research Fellow at the School of Cinematic Arts, University of Southern California

    Ahead of the Cannes Film Festival, the spotlight moved from movie stars and directors to the festival’s fashion rules.

    Cannes reminded guests to follow the standard black-tie dress code for evening events at the Grand Theatre Lumière – “long dresses and tuxedos” – while highlighting acceptable alternatives, such as cocktail dresses and pantsuits for women, and a black or navy suit with a tie for men.

    The real stir, however, came from two additions to the formal guidelines: a ban on nudity “for decency reasons” and a restriction on oversize garments.

    The new rules caught many stylists and stars by surprise, with some decrying the move as a regressive attempt to police clothing.

    It’s hard not to wonder whether this is part of some broader conservative cultural shift around the world.

    But I study the cultural and economic forces behind fashion and media, and I think a lot of the criticism of Cannes is unfounded. To me, the festival isn’t changing its identity. It’s reasserting it.

    Red carpet control

    Concerns about indecency on the red carpet have appeared before – most notably during the first televised Academy Awards in 1953.

    In 1952, the National Association of Radio and Television Broadcasters adopted a censorship code in response to concerns about television’s influence on young audiences. Among its rules for “decency and decorum” were guidelines against revealing clothing, suggestive movements or camera angles that emphasized body parts – all to avoid causing “embarrassment” to the viewers.

    To ensure that no actress would break the decency dress code, the Academy of Motion Picture Arts and Sciences hired acclaimed costume designer Edith Head as a fashion consultant for the show in 1953.

    In my book “Fashion on the Red Carpet,” I explain how Head equipped backstage staff with kits to deal with any sartorial emergencies that might arise. That same year, the balcony cameras at the Pantages Theatre accidentally peeked down into the actresses’ cleavage as they walked to the stage. From then on, a supply of tulle – a type of versatile fabric that can easily cover revealing openings that expose too much skin – was kept backstage.

    The 1960s posed new challenges. Youth fashion trends clashed with traditional dress codes and television censorship. In 1968, after actress Inger Stevens appeared on the red carpet wearing a mini skirt, the Academy sent a letter reminding attendees of the black-tie – preferably floor-length – dress code. When Barbra Streisand’s Scaasi outfit accidentally turned see-through under the lighting in 1969, Head again warned against “freaky, far-out, unusual fashion” ahead of the 1970 ceremony.

    However, in the 1970s, the Oscars eliminated Head’s fashion consultant position. Despite maintaining its black-tie dress code, the absence of a fashion consultant opened the door to some provocative attire, ranging from Cher’s see-through, sheer outfits, to Edy Williams’ provocative, barely-there getups.

    Once the fashion consultant position was eliminated for the Oscars, many attendees – like actress Edy Williams – tried to stand out from the crowd with provocative attire.

    Old rules in a new era

    Racy red carpet appearances have since become a hallmark of awards shows, particularly in the digital age.

    Extravagance and shock are a way for celebrities and brands to stand out amid a glut of social media content, especially as brands increasingly pay a fortune to turn celebrities into walking billboards.

    And in an era when red carpet looks are carefully curated ahead of time through partnerships with fashion brands, many celebrities expressed frustration about being unable to sport the outfits they had planned to wear at Cannes.

    Stylist Rose Forde lamented the restrictions, saying, “You should be able to express yourself as an artist, with your style however you feel,” while actress Chloë Sevigny described the code as “an old-fashioned archaic rule.”

    But I still can’t see the Cannes rules as part of any sort of broader conservative backlash.

    Whether at the Oscars or the MTV Video Music Awards, backlash over celebrities baring too much skin has gone on for decades. Cannes hasn’t been spared from controversy, either: There was Michelle Morgan’s bikini in 1946, La Cicciolina’s topless look in 1988, Madonna’s Jean Paul Gaultier lingerie in 1991, Leila Depina’s barely-there pearl outfit in 2023 and Bella Hadid’s sheer pantyhose dress in 2024, to name just a few.

    The festival has routinely reminded guests of its dress code, regardless of the cultural zeitgeist.

    The “decency” rule, for example, is actually required by French law. Article 222-32 of the French Criminal Code classifies showing private parts in public as a sexual offense, and can lead to a year in prison and a fine. While the legal definition hinges on intent and setting, the festival, as a public event, technically has to operate within that framework.

    Compared to white-tie events like the Nobel Prize ceremony or a state banquet, Cannes’ black-tie requirement is relatively flexible. It allows for cocktail-length dresses and even accommodates pants and flat sandals for women.

    Meanwhile, the worry about voluminous clothes points to a practical issue: the movement of bodies in tight spaces.

    Unlike the Met Gala – where the fashion spectacle is the focus, and its red carpet is a stage for photo-ops – Cannes is a film festival. The red carpet is the main path thousands of people use to enter the theater.

    A dramatic gown – like the one worn at the Met Gala by Cardi B in 2024 – could block others and cause delays. While a photo-op may be the primary goal for celebrities and the brands they promote, the festival has a screening schedule to stick to, and attendees must be able to easily access the venue and their seats.

    Red carpet rules are fluid. Sometimes they adapt to cultural shifts. Sometimes they resist them. And sometimes, they’re there to make sure you can fit in your seat in the movie theater.

  • MIL-OSI Submissions: Colorado’s fentanyl criminalization bill won’t solve the opioid epidemic, say the people most affected

    Source: The Conversation – USA – By Katherine LeMasters, Assistant Professor of Medicine, University of Colorado Boulder

    Colorado passed the Fentanyl Accountability and Prevention Bill in May 2022. The legislation made the possession of small amounts of fentanyl a felony, rather than a misdemeanor.

    Felonies are more likely than misdemeanors to result in a prison sentence.

    Time in prison is associated with an increased risk of fatal overdose in the year after release. People with felonies on their record often struggle to find a job or rent an apartment.

    In 2023, lawmakers in 46 states passed legislation similar to Colorado’s. They introduced more than 600 bills related to fentanyl criminalization and enacted over 100 other laws to attempt to curb the opioid epidemic.

    Possession of small amounts of ketamine, GHB and other criminalized drugs is also a felony in Colorado.

    I’m an assistant professor of medicine, social epidemiologist and community researcher who studies mass incarceration as a public health threat. I am a member of the Right Response Coalition, which advocates for community rather than criminal-legal responses to behavioral health needs in Colorado. Recently, my work has focused on how increasing criminal penalties for fentanyl possession in Colorado affects the individuals and communities most impacted by such laws.

    Our team conducted 31 interviews with Colorado policymakers, peer support specialists, law enforcement, community behavioral health providers and people providing behavioral health in prisons and jails to explore a variety of perspectives on Colorado’s Fentanyl Accountability and Prevention Bill and the role of the criminal-legal system in addressing substance use and overdose.

    Most of our interviewees agreed that criminalization alone wouldn’t solve the opioid epidemic.

    “You can’t incarcerate yourself to sobriety,” said a rural law enforcement officer. “You can’t incarcerate yourself out of the drug problem in America.”

    Criminalization of drug use

    Incarceration and substance use are deeply intertwined. The U.S. houses one-quarter of the world’s incarcerated population – largely due to policies created during the “war on Drugs” of the 1980s. The war on drugs included mandatory minimum sentencing for drug-related charges and “three strikes” laws that lengthened sentences after multiple charges.

    Today, one-fifth of the U.S. incarcerated population has a drug-related charge.

    People recently released from incarceration are more likely to overdose than the general public because their tolerance is greatly reduced following forced abstinence and there are not enough community-based treatment options.
    Erik McGregor/GettyImages

    Incarceration is often seen as a deterrent, but research shows it is not actually associated with reduced drug use. Instead, people recently released from incarceration are more likely to die of a fatal overdose and face a high likelihood of reincarceration.

    Perspectives of front-line workers

    All 31 of the participants in our study supported policies to prevent fentanyl overdoses. However, most thought that use of police and incarceration as avenues to do so was misguided.

    We spoke to some individuals who felt the bill was appropriate, but most felt that increased criminalization perpetuates stigma against people who use drugs. They also saw the law as ignoring the root causes of the opioid epidemic, which include a lack of voluntary community-based treatment options. They also said the law creates stressful law enforcement encounters that can perpetuate drug use as a coping mechanism.

    “It just seems like there’s no getting away from [the police], they’re everywhere,” said an urban peer support specialist. “I got arrested by the same cops, I don’t know how many times. And then it makes you want to try to be avoidant or run because they’re not going to help you.”

    Participants worried that the policy has an inadvertent chilling effect, deterring individuals from calling 911 when an overdose occurs.

    “Most people with substance abuse are not trying to report anything or get help for fear of going to jail,” one rural provider said. “It’s so stigmatized that everyone’s just scared to do that.”

    Participants largely thought that counties were using incarceration as a default treatment setting and that it wasn’t an ideal solution.

    “[I] don’t want to see [people] incarcerated, but I don’t want ‘em to die either,” said an urban peer support specialist.

    The people we interviewed pointed to a lack of community-based care options that could come before people are incarcerated. Those options include substance use treatment centers, mental health services and community health centers.

    Substance use treatment

    Colorado’s fentanyl bill did more than just increase penalties. It also provided additional funding for a state naloxone program and required that all jails provide medications for opioid use disorder.

    Along with increasing penalties, Colorado’s bill increased access to naloxone, an opioid-reversal drug.

    These medications include methadone, buprenorphine and extended-release naltrexone. All are part of an established public health strategy shown to reduce overdose deaths and opioid use. They’re also shown to increase engagement with non-jail-based treatment and reduce reincarceration.

    However, jail capacity and the lack of treatment options based in one’s community play a large role in which medications are offered and to whom. For example, only 11 out of Colorado’s 46 counties with a county jail have an opioid treatment program in the community that can dispense methadone. Therefore, some facilities do not offer all medications, or only offer medications to individuals with an active prescription or to certain populations such as pregnant people.

    Investing in community solutions

    Based on our study’s findings, my study co-authors and I believe increased criminal penalties should not be the solution for linking individuals to treatment. Instead, there should be more investment in long-term community solutions.

    One such solution is Denver’s Substance Use Navigation Program. The program sends behavioral health specialists to emergency calls to prevent legal involvement when someone is experiencing distress related to mental health, poverty, homelessness or substance use. In many cases, those individuals are then routed to services rather than jails.

    Our findings also lead us to believe there is a need for more participatory policymaking processes when it comes to fentanyl legislation, and that policymakers should more closely work with the people who will be most impacted by new legislation. Most of our participants agree.

    “[I] don’t think that [the] state realized how difficult it is,” said a rural provider about giving medication-assisted treatment in jail, an increasing need as more people are arrested for fentanyl possession. “They probably should come here and visit us.”

  • MIL-OSI Submissions: Data on sexual orientation and gender is critical to public health – without it, health crises continue unnoticed

    Source: The Conversation – USA – By John R. Blosnich, Associate Professor of Social Work, University of Southern California

    As part of the Trump administration’s efforts aimed at stopping diversity, equity and inclusion, the government has been restricting how it monitors public health. Along with cuts to federally funded research, the administration has targeted public health efforts to gather information about sexual orientation and gender identity.

    In the early days of the second Trump administration, the Centers for Disease Control and Prevention took down data and documents that included sexual orientation and gender identity from its webpages. For example, data codebooks for the Behavioral Risk Factor Surveillance System were replaced with versions that deleted gender identity variables. The Trump administration also ordered the CDC to delete gender identity from the National Violent Death Reporting System, the world’s largest database for informing prevention of homicide and suicide deaths.

    For many people, sexual orientation and gender identity may seem private and personal. So why is personal information necessary for public health?

    Decades of research have shown that health problems affect some groups more than others. As someone who has studied differences in health outcomes for over 15 years, I know that one of the largest health disparities for LGBTQ+ people is suicide risk. Without data on sexual orientation and gender identity, public health cannot do the work to sound the alarm on and address issues that affect not just specific communities, but society as a whole.

    Clinicians are concerned about the purging of health data that is essential to patient care.

    Alarms and benchmarks

    Health is determined by the interplay of several factors, including a person’s genetics, environment and personal life. Of these types of health information, data on personal lives can be the most difficult to collect because researchers must rely on people to voluntarily share this information with them. But details about people’s everyday lives are critical to understanding their health.

    Consider veteran status. Without information that identifies which Americans are military veterans, the U.S. would never have known that the rate of suicide deaths among veterans is several times higher than that of the general population. Identifying this problem encouraged efforts to reduce suicide among veterans and military service personnel.

    Studying the rates of different conditions occurring in different groups of people is a vital role of public health monitoring. First, rates can set off alarm bells. When people are counted, it becomes easier to pick up a problem that needs to be addressed.

    Second, rates can be a benchmark. Once the extent of a health problem is known, researchers can develop and test interventions. They can then determine if rates of that health problem decreased, stayed the same or increased after the intervention.

    My team reviewed available research on how sexual orientation and gender identity are related to differences in mortality. The results were grim.

    Of the 49 studies we analyzed, the vast majority documented greater rates of death from all causes for LGBTQ+ people compared with people who aren’t LGBTQ+. Results were worse for suicide: Nearly all studies reported that suicide deaths were more frequent among LGBTQ+ people. A great deal of other research supports this finding.

    Without data on sexual orientation and gender identity, these issues are erased.

    Lost data costs everyone

    Higher death rates among LGBTQ+ people affect everyone, not just people in the LGBTQ+ community. And when suicide is a major driver of these death rates, the costs increase.

    There are societal costs. Deaths from suicide result in lost productivity and medical services that cost the U.S. an estimated $484 billion per year. There are also human costs. Research suggests that for every suicide death, about 135 people are directly affected by the loss, experiencing grief, sadness and anger.

    President Donald Trump’s targeting of research on sexual orientation and gender identity comes at a time when more Americans than ever – an estimated 24.4 million adults – identify as lesbian, gay, bisexual or transgender. That’s more than the entire population of Florida.

    LGBTQ+ people live in every state in the country, where they work as teachers, executives, janitors, nurses, mechanics, artists and every other profession or role that help sustain American communities. LGBTQ+ people are someone’s family members, and they are raising families of their own. LGBTQ+ people also pay taxes to the government, which are partly spent on monitoring the nation’s health.

    Stopping data collection of sexual orientation and gender identity does not protect women, or anyone else, as the Trump administration claims. Rather, it serves to weaken American public health. I believe counting all Americans is the path to a stronger, healthier nation because public health can then do its duty of detecting when a community needs help.

  • MIL-OSI Submissions: Sleep loss rewires the brain for cravings and weight gain – a neurologist explains the science behind the cycle

    Source: The Conversation – USA – By Joanna Fong-Isariyawongse, Associate Professor of Neurology, University of Pittsburgh

    Getting enough sleep is one of the most effective ways to restore metabolic balance in the brain and body. SimpleImages/Moment via Getty Images

    You stayed up too late scrolling through your phone, answering emails or watching just one more episode. The next morning, you feel groggy and irritable. That sugary pastry or greasy breakfast sandwich suddenly looks more appealing than your usual yogurt and berries. By the afternoon, chips or candy from the break room call your name. This isn’t just about willpower. Your brain, short on rest, is nudging you toward quick, high-calorie fixes.

    There is a reason why this cycle repeats itself so predictably. Research shows that insufficient sleep disrupts hunger signals, weakens self-control, impairs glucose metabolism and increases your risk of weight gain. These changes can occur rapidly, even after a single night of poor sleep, and can become more harmful over time if left unaddressed.

    I am a neurologist specializing in sleep science and its impact on health.

    Sleep deprivation affects millions. According to the Centers for Disease Control and Prevention, more than one-third of U.S. adults regularly get less than seven hours of sleep per night. Nearly three-quarters of adolescents fall short of the recommended 8-10 hours sleep during the school week.

    While anyone can suffer from sleep loss, essential workers and first responders, including nurses, firefighters and emergency personnel, are especially vulnerable due to night shifts and rotating schedules. These patterns disrupt the body’s internal clock and are linked to increased cravings, poor eating habits and elevated risks for obesity and metabolic disease. Fortunately, even a few nights of consistent, high-quality sleep can help rebalance key systems and start to reverse some of these effects.

    How sleep deficits disrupt hunger hormones

    Your body regulates hunger through a hormonal feedback loop involving two key hormones.

    Ghrelin, produced primarily in the stomach, signals that you are hungry, while leptin, which is produced in the fat cells, tells your brain that you are full. Even one night of restricted sleep increases the release of ghrelin and decreases leptin, which leads to greater hunger and reduced satisfaction after eating. This shift is driven by changes in how the body regulates hunger and stress. Your brain becomes less responsive to fullness signals, while at the same time ramping up stress hormones that can increase cravings and appetite.

    These changes are not subtle. In controlled lab studies, healthy adults reported increased hunger and stronger cravings for calorie-dense foods after sleeping only four to five hours. The effect worsens with ongoing sleep deficits, which can lead to a chronically elevated appetite.

    Sleep is as important as diet and exercise in maintaining a healthy weight.

    Why the brain shifts into reward mode

    Sleep loss changes how your brain evaluates food.

    Imaging studies show that after just one night of sleep deprivation, the prefrontal cortex, which is responsible for decision-making and impulse control, has reduced activity. At the same time, reward-related areas such as the amygdala and the nucleus accumbens, a part of the brain that drives motivation and reward-seeking, become more reactive to tempting food cues.

    In simple terms, your brain becomes more tempted by junk food and less capable of resisting it. Participants in sleep deprivation studies not only rated high-calorie foods as more desirable but were also more likely to choose them, regardless of how hungry they actually felt.

    Your metabolism slows, leading to increased fat storage

    Sleep is also critical for blood sugar control.

    When you’re well rested, your body efficiently uses insulin to move sugar out of your bloodstream and into your cells for energy. But even one night of partial sleep can reduce insulin sensitivity by up to 25%, leaving more sugar circulating in your blood.

    If your body can’t process sugar effectively, it’s more likely to convert it into fat. This contributes to weight gain, especially around the abdomen. Over time, poor sleep is associated with higher risk for Type 2 diabetes and metabolic syndrome, a group of health issues such as high blood pressure, belly fat and high blood sugar that raise the risk for heart disease and diabetes.

    On top of this, sleep loss raises cortisol, your body’s main stress hormone. Elevated cortisol encourages fat storage, especially in the abdominal region, and can further disrupt appetite regulation.

    Sleep is your metabolic reset button

    In a culture that glorifies hustle and late nights, sleep is often treated as optional. But your body doesn’t see it that way. Sleep is not downtime. It is active, essential repair. It is when your brain recalibrates hunger and reward signals, your hormones reset and your metabolism stabilizes.

    Just one or two nights of quality sleep can begin to undo the damage from prior sleep loss and restore your body’s natural balance.

    So the next time you find yourself reaching for junk food after a short night, recognize that your biology is not failing you. It is reacting to stress and fatigue. The most effective way to restore balance isn’t a crash diet or caffeine. It’s sleep.

    Sleep is not a luxury. It is your most powerful tool for appetite control, energy regulation and long-term health.

  • MIL-OSI Submissions: Nostalgic foods and scents like fresh-cut grass and hamburgers grilling bring comfort, connection and well-being

    The foods and scents we associate with our childhoods can provide a meaningful source of comfort and connection. zeljkosantrac/E+ via Getty Images

    Walking around my neighborhood in the evening, I am hit by the smells of summer: fresh-cut grass, hamburgers grilling and a hint of swimming pool chlorine. These are also the smells of summers from my adolescence, and they remind me of Friday evenings at the community pool with my friends and our families gathered around picnic tables between swims. The memories always brings a smile to my face.

    As a social psychologist, I shouldn’t feel surprised to experience this warm glow. My research focuses on nostalgia – a sentimental longing for treasured moments in our personal pasts – and how nostalgia is linked to our well-being and feelings of connection with others.

    Triggered by sensory stimuli such as music, scents and foods, nostalgia has the power to mentally transport us back in time. This might be to important occasions, to moments of triumph and – importantly – moments revolving around close family and friends and other important people in our lives.

    As it turns out, this experience is good for us.

    How the concept of nostalgia evolved

    For centuries, nostalgia was considered unhealthy.

    In the 1600s, a Swiss medical student named Johannes Hofer studied mercenaries in the Italian and French lowlands who longed desperately for their mountain homelands. Witnessing their weeping and despondency, he coined the term nostalgia and attributed it to a brain disease. Other thinkers of the time echoed this view, which persisted through the 18th and 19th centuries.

    However, early thinkers made an error: They assumed that nostalgia was causing unpleasant symptoms. It may have been the reverse. Unpleasant experiences, such as loneliness and grief, can arouse nostalgia, which can then help people cope more effectively with these hardships.

    Today, researchers view nostalgia as a predominantly positive, albeit bittersweet, emotional experience that serves as a source of psychological well-being. Importantly, this view has been supported by scientific research.

    Part of what makes nostalgia so intense is the bittersweet blend of feelings that it brings up.

    How nostalgia inspires connection and belonging

    Nostalgia provides many benefits. It enhances feelings of optimism and inspiration and makes people view themselves more positively. When people feel nostalgic, they feel a greater sense that their lives are meaningful.

    The social benefits of nostalgia are particularly well supported. Nostalgia increases empathy and the willingness of people to give to those around them, such as volunteering for community events and donating to charities.

    Nostalgia also makes people feel more socially connected to their loved ones by enhancing feelings that they are loved by, connected to, protected by and trusting of others. Nostalgia helps people feel more secure in their close relationships and enhances relationship satisfaction.

    While nostalgia is a universal experience, it is also deeply personal. The moments for which we are each nostalgic and the stimuli that might trigger our nostalgic memories can vary from one person to the next depending on the experiences that each of us have. But people within the same culture may find similar stimuli to be nostalgic for them. In a 2013 study, for instance, my team found that American participants rated pumpkin pie spice as the most nostalgia-evoking scent out of a variety of options.

    The nostalgic power of scents and foods

    In 1922, the French novelist Marcel Proust wrote about the strength of scents and foods to elicit nostalgia. He vividly described how the experience of smelling and eating a tea-soaked cake mentally transported him back to childhood experiences with his aunt in her home and village. This sort of experience is now often referred to as the Proust effect.

    Science has confirmed what Proust described. Our olfactory system, the sensory system responsible for our sense of smell, is closely linked to brain structures associated with emotions and autobiographical memory. Smells combine with tastes to create our perception of flavor.

    Foods also tend to be central to social gatherings, making them easily associated with these memories. For instance, a summer barbecue might feel incomplete to some without slices of juicy watermelon. And homemade pumpkin pie may be an essential dessert at many Thanksgiving tables. The watermelon or pie may then serve as what are known in social psychology as social surrogates, foods that serve as stand-ins for valued relationships due to their inclusion at past occasions with loved ones.

    My research team and I wanted to know how people benefited from feeling nostalgic when they encountered the scents and foods of their pasts. We began in 2011 by exposing study participants to 33 scents and chose 12 of them for our study. Participants rated some scents, such as pumpkin pie spice and baby powder, as highly evocative of nostalgia, while rating others – such as money and cappuccino –as less evocative.

    Those who experienced more nostalgia when smelling the scents experienced greater positive emotions, greater self-esteem, greater feelings of connection to their past selves, greater optimism, greater feelings of social connectedness and a greater sense that life is meaningful.

    We came to similar conclusions when we studied nostalgia for foods. Foods seemed to be more strongly linked to nostalgia than either scents or music when comparing the amount of nostalgia our participants experienced for foods to what previous research participants experienced for scents and songs. More recently, we found that nostalgic foods are comforting and that people find nostalgic foods comforting because those nostalgic foods remind them of important or meaningful moments with their loved ones.

    For some, a summer barbecue wouldn’t be complete without the smell and taste of juicy watermelon.

    Balancing benefits and trade-offs

    Although nostalgia can be associated with foods that should be eaten only in moderation – such as burgers and cookies – there are other ways to channel our nostalgia through foods.

    We can have nostalgia with healthy foods. For instance, orange slices remind me of halftime at childhood soccer matches. And many people, including our research participants, feel intense nostalgia around watermelon. Other researchers have found that tofu is a nostalgic food for Chinese participants.

    But when nostalgia does involve consumption of unhealthy foods, there are still other ways to experience it without the health trade-offs. We found that participants experienced the benefits of food-evoked nostalgia just from imagining and writing about the foods – no consumption necessary. Other researchers have found that drawing comforting foods can enhance well-being. Even consuming less healthy foods more mindfully helps people enjoy their food while reducing their caloric consumption.

    Once seen as detrimental to our health, nostalgia provides us with an opportunity to reap numerous rewards. With nostalgic foods, we might be able to nourish both our bodies and our psychological health.

  • MIL-OSI Submissions: When you lose your health insurance, you may also lose your primary doctor – and that hurts your health

    Source: The Conversation – USA – By Jane Tavares, Senior Research Fellow and Lecturer of Gerontology, UMass Boston

    When you lose your health insurance or switch to a plan that skimps on preventive care, something critical breaks.

    The connection to your primary care provider, usually a doctor, gets severed. You stop getting routine checkups. Warning signs get missed. Medical problems that could have been caught early become emergencies. And because emergencies are both dangerous and expensive, your health gets worse while your medical bills climb.

    As gerontology researchers who study health and financial well-being in later life, we’ve analyzed how someone’s ties to the health care system strengthen or unravel depending on whether they have insurance coverage. What we’ve found is simple: Staying connected to a trusted doctor keeps you healthier and saves the system money. Breaking that link does just the opposite.

    And that’s exactly what has us worried right now. Members of Congress are debating whether to make major cuts to Medicaid and other social safety net programs. If the Senate passes its own version of the tax-and-spending package that the House approved in May 2025, millions of Americans will soon face exactly this kind of disruption – with big consequences for their health and well-being.

    How people end up uninsured

    Someone can lose their health insurance for a number of reasons. For many Americans, coverage is tied to employment. Being fired, retiring before you turn 65 and become eligible to enroll in the Medicare program, or even getting a new job can mean losing insurance. Others wind up uninsured due to a different array of changes: moving to a different state, getting divorced or aging out of a parent’s plan after their 26th birthday.

    And those who buy their own coverage may find that they can no longer afford the premiums. In 2024, average premiums on the individual market exceeded more than US$600 per month for many adults, even with subsidies.

    Government-sponsored insurance programs can also leave you vulnerable to this predicament. The Senate is currently considering its own version of a tax-and-spending bill the House of Representatives passed in May that would make cuts and changes to Medicaid. If the provisions in the House bill are enacted, millions of Americans who get health insurance through Medicaid – a health insurance program jointly run by the federal government and the states that is mainly for people who have low incomes or disabilities – would lose their coverage, according to the nonpartisan Congressional Budget Office.

    Medicaid was established in the 1960s, explains a scholar of the program’s history.

    Consequences of becoming uninsured

    Health insurance is more than a way to pay medical bills; it’s a doorway into the health care system itself. It connects people to health care providers who come to know their medical history, their medications and their personal circumstances.

    When that door closes, the effects are immediate. Uninsured people are much less likely to have a usual source of care – typically a doctor or another primary care provider or clinic you know and trust. That relationship acts as a foundation for managing chronic conditions, staying current with preventive screenings and getting guidance when new symptoms arise.

    Researchers have found that adults who go uninsured for even six months become significantly more likely to postpone care or forgo it altogether to save money. In practical terms, this means they’re less likely to be examined by someone who knows their medical history and can spot red flags early.

    The Affordable Care Act, the landmark health care law enacted during the Obama administration, made the number of Americans without insurance plummet. The share of people without insurance fell from 16% in 2010 to 7.7% in 2023.

    The people who got insurance coverage, particularly those who were middle age, saw big improvements in their health.

    Researching the results

    In research that looked at data collected from 2014 to 2020, we followed what happened to 12,000 adults who were 50 or older and lived across the nation.

    Our research team analyzed how their experiences changed when they lost, and sometimes later regained, a regular source of care during those six years.

    Many of the participants in this study had multiple chronic conditions like diabetes, hypertension and heart disease.

    The results were striking.

    Those who didn’t see the same provider on a regular basis were far less likely to feel heard or respected by health care professionals. They had fewer medical appointments, filled fewer prescriptions and were less likely to follow through with recommended treatments.

    Their health also deteriorated considerably over the six years. Their blood pressure and blood sugar levels rose, and they had more elevated indicators of kidney impairment compared with their counterparts who had regular care providers.

    The longer they went without consistent health care, the worse these clinical markers became.

    Warning signs

    Preventive care is one of the best tools that both patients and their health care providers have to head off major health problems. This care includes screenings like cholesterol and blood pressure checks, mammograms, PAP smears and prostate exams, as well as routine vaccinations. But most people only get preventive care when they stay engaged with the health care system.

    And that’s far more likely when you have stable and comprehensive health insurance coverage.

    Our research team also examined what happened to preventive care based on whether the participants had a regular doctor. We found that those who kept seeing the same providers were almost three times more likely to get basic preventive services than those who did not.

    Over time, these missed preventive care opportunities can add up to a big problem. They can turn what could have been a manageable issue into an emergency room visit or a long, expensive hospital stay.

    For example, imagine a man in his 50s who no longer gets cholesterol screenings after losing insurance coverage. Over several years, his undiagnosed high cholesterol leads to a heart attack that could have been prevented with early medication. Or a woman who skips mammograms because of out-of-pocket costs, only to face a late-stage cancer diagnosis that might have been caught years earlier.

    Waiting too long to deal with a health condition can mean you make a trip to the emergency room, increasing the cost of care for you and others.

    Shifting the costs

    Patients whose conditions take too long to be diagnosed aren’t the only ones who pay the price.

    We also studied how stable care relationships affect health care spending. To do this, we linked Medicare claims cost data to our original study and tracked the medical costs of the same adults age 50 and older from 2014 to 2020. One of our key findings is that people with regular care providers were 38% less likely to incur above-average health care costs.

    These savings aren’t just for patients – they ripple through the entire health care system. Primary care stability lowers costs for both public and private health insurers and, ultimately, for taxpayers.

    But when people lose their health care coverage, those savings disappear.

    Emergency rooms see more uninsured patients seeking care that could have been handled earlier and more cheaply in a clinic or doctor’s office. While hospitals are legally required to provide emergency care regardless of a patient’s ability to pay, much of the resulting cost goes unreimbursed.

    Hospitals foot the bill for about two-thirds of those losses. They pass the other third along to private insurance companies through higher hospital fees. Those insurers, in turn, raise their customers’ premiums. Larger taxpayer subsidies can then be required to keep hospitals open.

    Seeing Medicaid as a lifeline

    For the nearly 80 million Americans enrolled in Medicaid, the program provides more than coverage.

    It contributes to the health care stability our research shows is critical for good health. Medicaid makes it possible for many Americans with serious medical conditions to have a regular doctor, get routine preventive services and have someone to turn to when symptoms arise – even when they have low incomes. It helps prevent health care from becoming purely crisis-driven.

    As Congress considers cutting Medicaid funding by hundreds of billions of dollars, we believe that lawmakers should realize that scaling back coverage would break the fragile links between millions of patients and the providers who know them best.

  • MIL-OSI Submissions: Work requirements are better at blocking benefits for low-income people than they are at helping those folks find jobs

    Source: The Conversation – USA (2) – By Anne Whitesell, Assistant Professor of Political Science, Miami University

    Republican lawmakers have been battling over a bill that includes massive tax and spending cuts. Much of their disagreement has been over provisions intended to reduce the cost of Medicaid.

    The popular health insurance program, which is funded by both the federal and state governments, covers about 78.5 million low-income and disabled people – more than 1 in 5 Americans.

    On May 22, 2025, the House of Representatives narrowly approved the tax, spending and immigration bill. The legislation, which passed without any support from Democrats, is designed to reduce federal Medicaid spending by requiring anyone enrolled in the program who appears to be able to get a job to either satisfy work requirements or lose their coverage. It’s still unclear, however, whether Senate Republicans would support that provision.

    Although there are few precedents for such a mandate for Medicaid, other safety net programs have been enforcing similar rules for nearly three decades. I’m a political scientist who has extensively studied the work requirements of another safety net program: Temporary Assistance for Needy Families.

    As I explain in my book, “Living Off the Government? Race, Gender, and the Politics of Welfare,” work requirements place extra burdens on low-income families but do little to lift them out of poverty.

    Work requirements for TANF

    TANF gives families with very low incomes some cash they can spend on housing, food, clothing or whatever they need most. The Clinton administration launched it as a replacement for a similar program, Aid to Families with Dependent Children, in 1996. At the time, both political parties were eager to end a welfare system they believed was riddled with abuse. A big goal with TANF was ending the dependence of people getting cash benefits on the government by moving them from welfare to work.

    Many people were removed from the welfare rolls, but not because work requirements led to economic prosperity. Instead, they had trouble navigating the bureaucratic demands.

    TANF is administered by the states. They can set many rules of their own, but they must comply with an important federal requirement: Adult recipients have to work or engage in an authorized alternative activity for at least 30 hours per week. The number of weekly hours is only 20 if the recipient is caring for a child under the age of 6.

    The dozen activities or so that can count toward this quota range from participating in job training programs to engaging in community service.

    Some adults enrolled in TANF are exempt from work requirements, depending on their state’s own policies. The most common exemptions are for people who are ill, have a disability or are over age 60.

    To qualify for TANF, families must have dependent children; in some states pregnant women also qualify. Income limits are set by the state and range from US$307 a month for a family of three in Alabama to $2,935 a month for a family of three in Minnesota.

    Adult TANF recipients face a federal five-year lifetime limit on benefits. States can adopt shorter time limits; Arizona’s is 12 months.

    An administrative burden

    Complying with these work requirements generally means proving that you’re working or making the case that you should be exempt from this mandate. This places what’s known as an “administrative burden” on the people who get cash assistance. It often requires lots of documentation and time. If you have an unpredictable work schedule, inconsistent access to child care or obligations to care for an older relative, this paperwork is hard to deal with.

    What counts as work, how many hours must be completed and who is exempt from these requirements often comes down to a caseworker’s discretion. Social science research shows that this discretion is not equally applied and is often informed by stereotypes.

    The number of people getting cash assistance has fallen sharply since TANF replaced Aid to Families with Dependent Children. In some states caseloads have dropped by more than 50% despite significant population growth.

    Some of this decline happened because recipients got jobs that paid them too much to qualify. The Congressional Budget Office, a nonpartisan office that provides economic research to Congress, attributes, at least in part, an increase in employment among less-educated single mothers in the 1990s to work requirements.

    Not everyone who stopped getting cash benefits through TANF wound up employed, however. Other recipients who did not meet requirements fell into deep poverty.

    Regardless of why people leave the program, when fewer low-income Americans get TANF benefits, the government spends less money on cash assistance. Federal funding has remained flat at $16.5 billion since 1996. Taking inflation into account, the program receives half as much funding as when it was created. In addition, states have used the flexibility granted them to direct most of their TANF funds to priorities other than cash benefits, such as pre-K education.

    Many Americans who get help paying for groceries through the Supplemental Nutrition Assistance Program are also subject to work requirements. People the government calls “able-bodied adults without dependents” can only receive SNAP benefits for three months within a three-year period if they are not employed.

    A failed experiment in Arkansas

    Lawmakers in Congress and in statehouses have debated whether to add work requirements for Medicaid before. More than a dozen states have applied for waivers that would let them give it a try.

    When Arkansas instituted Medicaid work requirements in 2018, during the first Trump administration, it was largely seen as a failure. Some 18,000 people lost their health care coverage, but employment rates did not increase.

    After a court order stopped the policy in 2019, most people regained their coverage.

    Georgia is currently the only state with Medicaid work requirements in effect, after implementing a waiver in July 2023. The program has experienced technical difficulties and has had trouble verifying work activities.

    Other states, including Idaho, Indiana and Kentucky, are already asking the federal government to let them enforce Medicaid work requirements.

    What this may mean for Medicaid

    The multitrillion-dollar bill the House passed 215-214 would introduce Medicaid work requirements nationwide by late 2026 for childless adults age 19 to 64, with some exemptions.

    But most people covered by Medicaid in that age range are already working, and those who are not would likely be eligible for work requirement waivers. An analysis by KFF – a nonprofit that informs the public about health issues – shows that in 2023, 44% of Medicaid recipients were working full time and another 20% were working part time. In 2023, that was more than 16 million Americans.

    About 20% of the American adults under 65 who are covered by Medicaid are not working due to illness or disability, or because of caregiving responsibilities, according to KFF. This includes both people caring for young children and those taking care of relatives with an illness or disability. In my own research, I read testimony from families seeking work exemptions because caregiving, including for children with disabilities, was a full-time job.

    The rest of the adults under 65 with Medicaid coverage are not working because they are in school, are retired, cannot find work or have some other reason. It’s approximately 3.9 million Americans. Depending on what counts as “work,” they may be meeting any requirements that could be added to the program.

    The Congressional Budget Office estimates that introducing Medicaid work requirements would save around $300 billion over a decade. Given past experience with work requirements, it is unlikely those savings would come from Americans finding jobs.

    My research suggests it’s more likely that the government would trim spending by taking away the health insurance of people eligible for Medicaid coverage who get tangled up in red tape.

  • MIL-OSI Submissions: Critical minerals don’t belong in landfills – microwave tech offers a cleaner way to reclaim them from e-waste

    Source: The Conversation – USA (2) – By Terence Musho, Associate Professor of Engineering, West Virginia University

    Broken electronics still contain valuable critical minerals. Beeldbewerking/iStock/Getty Images Plus

    When the computer or phone you’re using right now blinks its last blink and you drop it off for recycling, do you know what happens?

    At the recycling center, powerful magnets will pull out steel. Spinning drums will toss aluminum into bins. Copper wires will get neatly bundled up for resale. But as the conveyor belt keeps rolling, tiny specks of valuable, lesser-known materials such as gallium, indium and tantalum will be left behind.

    Those tiny specks are critical materials. They’re essential for building new technology, and they’re in short supply in the U.S. They could be reused, but there’s a problem: Current recycling methods make recovering critical minerals from e-waste too costly or hazardous, so many recyclers simply skip them.

    Sadly, most of these hard-to-recycle materials end up buried in landfills or get mixed into products like cement. But it doesn’t have to be this way. New technology is starting to make a difference.

    A treasure trove of critical materials is often overlooked in e-waste, including gallium in LEDs, indium in LCDs, and tantalum in surface mount capacitors.

    As demand for these critical materials keeps growing, discarded electronics can become valuable resources. My colleagues and I at West Virginia University are developing a new technology to change how we recycle. Instead of using toxic chemicals, our approach uses electricity, making it safer, cleaner and more affordable to recover critical materials from electronics.

    How much e-waste are we talking about?

    Americans generated about 2.7 million tons of electronic waste in 2018, according to the latest federal data. Including uncounted electronics, a survey by the United Nations suggests that the U.S. recycles only about 15% of its total e-waste.

    Even worse, nearly half the electronics that people in Northern America sent to recycling centers end up shipped overseas. They often land in scrapyards, where workers may use dangerous methods like burning or leaching using harsh chemicals to pull out valuable metals. These practices can harm both the environment and workers’ health. That’s why the Environmental Protection Agency restricts these methods in the U.S.

    The tiny specks matter

    Critical minerals are in most of the technology around you. Every phone screen has a super-thin layer of a material called indium tin oxide. LEDs glow because of a metal called gallium. Tantalum stores energy in tiny electronic parts called capacitors.

    All of these materials are flagged as “high risk” on the U.S. Department of Energy’s critical materials list. That means the U.S. relies heavily on these materials for important technologies, but their supply could be easily disrupted by conflicts, trade disputes or shortages.

    Right now, just a few countries, including China, control most of the mining, processing and recovery of these materials, making the U.S. vulnerable if those countries decide to limit exports or raise prices.

    These materials aren’t cheap, either. For example, the U.S. Geological Survey reports that gallium was priced between US$220 to $500 per kilogram in 2024. That’s 50 times more expensive than common metals like copper, at $9.48 per kilogram in 2024.

    Revolutionizing recycling with microwaves

    At West Virginia University’s Department of Mechanical, Materials and Aerospace Engineering, I and materials scientist Edward Sabolsky asked a simple question: Could we find a way to heat only specific parts of electronic waste to recover these valuable materials?

    If we could focus the heat on just the tiny specks of critical minerals, we might be able to recycle them easily and efficiently.

    The solution we found: microwaves.

    This equipment isn’t very different from the microwave ovens you use to heat food at home, just bigger and more powerful. The basic science is the same – electromagnetic waves cause electrons to oscillate, creating heat.

    In our approach, though, we’re not heating water molecules like you do when cooking. Instead, we heat carbon, the black residue that collects around a candle flame or car tailpipe. Carbon heats up much faster in a microwave than water does. But don’t try this at home; your kitchen microwave wasn’t designed for such high temperatures.

    West Virginia University researchers are using this experimental microwave reactor to recycle critical materials from end-of-life electronics.
    Ansan Pokharel/West Virginia University, CC BY

    In our recycling method, we first shred the electronic waste, mix it with materials called fluxes that trap impurities, and then heat the mixture with microwaves. The microwaves rapidly heat the carbon that comes from the plastics and adhesives in the e-waste. This causes the carbon to react with the tiny specks of critical materials. The result: a tiny piece of pure, sponge-like metal about the size of a grain of rice.

    This metal can then be easily separated from leftover waste using filters.

    So far, in our laboratory tests, we have successfully recovered about 80% of the gallium, indium and tantalum from e-waste, at purities between 95% and 97%. We have also demonstrated how it can be integrated with existing recycling processes.

    Why the Department of Defense is interested

    Our recycling technology got its start with help from a program funded by the Defense Department’s Advanced Research Projects Agency, or DARPA.

    Many important technologies, from radar systems to nuclear reactors, depend on these special materials. While the Department of Defense uses less of them than the commercial market, they are a national security concern.

    We’re planning to launch larger pilot projects next to test the method on smartphone circuit boards, LED lighting parts and server cards from data centers. These tests will help us fine-tune the design for a bigger system that can recycle tons of e-waste per hour instead of just a few pounds. That could mean producing up to 50 pounds of these critical minerals per hour from every ton of e-waste processed.

    If the technology works as expected, we believe this approach could help meet the nation’s demand for critical materials.

    How to make e-waste recycling common

    One way e-waste recycling could become more common is if Congress held electronics companies responsible for recycling their products and recovering the critical materials inside. Closing loopholes that allow companies to ship e-waste overseas, instead of processing it safely in the U.S., could also help build a reserve of recovered critical minerals.

    But the biggest change may come from simple economics. Once technology becomes available to recover these tiny but valuable specks of critical materials quickly and affordably, the U.S. can transform domestic recycling and take a big step toward solving its shortage of critical materials.

  • MIL-OSI Submissions: Public health and private equity: What the Walgreens buyout could mean for the future of pharmacy care

    Source: The Conversation – USA (2) – By Patrick Aguilar, Professor of Practice of Organizational Behavior, Washington University in St. Louis

    Pharmacies are more than just stores – they’re vital links between people and their health care.

    One of us, Patrick, witnessed this firsthand in 2003 while working as a pharmacy technician at Walgreens in a midsize West Texas town. Each day involved handling hundreds of prescriptions as they moved through the system – meticulously counting pills, deciphering doctors’ handwriting and sorting out confusing insurance issues. The experience revealed that how pharmacies are owned and managed is as much a public health issue as it is a financial one.

    Fast-forward to today, and Walgreens – one of the world’s largest pharmacy chains, which filled nearly 800 million U.S. prescriptions in 2024 – is at a turning point. In March, the company announced it would be acquired by private equity firm Sycamore Partners for US$10 billion, just 10% of its peak market value. That deal takes the storied pharmacy chain off the public market for the first time in nearly 100 years.

    We’re professors who study the intersection of medicine and business, and we think this deal offers a window into the future of pharmacy care. It matters not just to pharmacists but also to the tens of millions of Americans who rely on outlets like Walgreens to meet their everyday health needs.

    The rise and struggles of Walgreens

    A lot has changed in the pharmacy industry since 1901, when Charles R. Walgreen Sr. purchased the Chicago drugstore where he served as a pharmacist. The company went public in 1927, expanded rapidly throughout the 20th century and grew to 8,000 stores by 2013. By 2014, a merger with the European pharmacy chain Alliance Boots made Walgreens one of the largest pharmacy chains in the world.

    More recently, however, the picture for the pharmacy industry hasn’t been so rosy. Labor costs have risen. Front-end retail sales – things like snacks, greeting cards and cosmetics – have fallen. And financial pressures from pharmacy benefit managers – those third-party groups that manage the cost of prescription drug benefits on the behalf of insurers – have grown.

    All of these things have significantly constrained revenues across the industry, leading stores to shutter. Some estimates suggest that as many as one-third of U.S. retail pharmacies have closed since 2010.

    Against that backdrop, Sycamore Partners’ March acquisition of Walgreens raises big questions. What does Sycamore see in this investment, and what might their strategies imply about the future of American pharmacy care?

    Framing the private equity bet

    Private equity firms typically buy companies, streamline their operations and seek to sell them for a profit within five to seven years of the acquisition.

    This growing movement of private equity into the global economy is by no means limited to health care. In 2020, private equity firms employed 11.7 million U.S. workers, or about 7% of the country’s total workforce. The total assets under management by such investors have grown by over 11% annually over the past two decades, a trend that’s expected to continue.

    In looking at Walgreens, Sycamore, like many of these businesses, likely sees an opportunity to buy low, cut costs and improve profitability. One survey of private equity investors found that the most common self-reported sources of value creation in these deals for companies of Sycamore’s size were changing the product and marketing it more robustly to drive demand, changing incentives for those within the business, and facilitating a high-value exit.

    While private owners may have more patience than public markets, critics argue that private equity firms tend to have a short-term focus, looking for quick, predictable services of margin improvement – like, for example, cutting jobs.

    There’s some evidence in favor of that claim. One study found that employment often drops in the years following a private equity buyout. And if the focus shifts to repaying debt or prepping for resale, long-term projects, such as investing in future innovation, can get deprioritized.

    The history of privatized public companies offers a mix of successes and failures. Dell Technologies and hotel chain Hilton are two prominent examples of companies that went private, restructured successfully and came back stronger. In those cases, going private helped management focus without the constant pressure of quarterly earnings reports.

    On the other hand, companies such as Toys R Us, which was taken private in 2005 and filed for bankruptcy in 2018, show how high debt and missed innovation can lead to collapse.

    What’s next for Walgreens

    So, where does this leave Walgreens − and the investors involved in the deal?

    If part of the returns will be driven by “buying low” – the easiest indicator of potential future success to measure as of today – Sycamore started well: Its purchase price represents a mere 8% premium over the market trading value on the day of the announcement, significantly less than the 46% seen across industries in 2023. That said, Sycamore financed 83.4% of the purchase with debt, a number on the high end for these kinds of transactions. Health care groups have pointed to this number while raising concerns that innovation-focused investments may take a back seat to debt obligations.

    As the dust settles on the purchase, Sycamore has indicated an interest in splitting Walgreens into three business units: one focused on U.S. pharmacies, one on U.K. pharmacies and one on U.S. primary health care through its VillageMD subsidiary.

    That’s not unusual: Sycamore has used a similar approach before with its investment in the office supply retailer Staples, a strategy that has garnered strong financial returns but been called into question for its long-term sustainability.

    Given the significant financial challenges VillageMD has faced since its acquisition by Walgreens, this represents an opportunity to separately evaluate and optimize its performance. Meanwhile, Sycamore’s historic focus on retail and customer-focused businesses might help it modernize the in-store experience or optimize staffing.

    For more than a century, Walgreens has survived and adapted to sweeping changes in retail. Now, it’s entering a new chapter – one that could reshape not just its own future but the role of pharmacies in American life.

    Will Sycamore help Walgreens thrive, using its resources to strengthen services and deliver more value to customers? Or will pressure to generate quick returns create problems? Either way, the answer matters – not just for investors but for anyone who’s ever relied on their neighborhood pharmacy to stay healthy.

  • MIL-OSI Submissions: Smartphones are once again setting the agenda for justice as the Latino community documents ICE actions

    Source: The Conversation – USA – By Allissa V. Richardson, Associate Professor of Journalism, USC Annenberg School for Communication and Journalism

    Smartphone witnessing helped spur the anti-ICE protests in Los Angeles. AP Photo/Ethan Swope

    It has been five years since May 25, 2020, when George Floyd gasped for air beneath the knee of a Minneapolis police officer at the corner of 38th Street and Chicago Avenue. Five years since 17-year-old Darnella Frazier stood outside Cup Foods, raised her phone and bore witness to nine minutes and 29 seconds that would galvanize a global movement against racial injustice.

    Frazier’s video didn’t just show what happened. It insisted the world stop and see.

    Today, that legacy continues in the hands of a different community, facing different threats but wielding the same tools. Across the United States, Latino organizers are raising their phones, not to go viral but to go on record. They livestream Immigration and Customs Enforcement raids, film family separations and document protests outside detention centers. Their footage is not merely content. It is evidence, warning – and resistance.

    Here in Los Angeles where I teach journalism, for example, several images have seared themselves into public memory. One viral video shows a shackled father stepping into a white, unmarked van as his daughter sobs behind the camera, pleading with him not to sign any official documents. He turns, gestures for her to calm down, and blows her a kiss. In another video, filmed across town, Los Angeles Police Department officers on horseback charge into crowds of peaceful protesters, swinging wooden batons with chilling precision.

    In Spokane, Washington, residents form a spontaneous human chain around their neighbors mid-raid, their bodies and cameras erecting a barricade of defiance. In San Diego, a video shows white allies yelling “Shame!” as they chase a car full of National Guard troops from their neighborhood.

    The impact of smartphone witnessing has been immediate and unmistakable – visceral at street level, seismic in statehouses. On the ground, the videos helped inspire a “No Kings” movement, which organized protests in all 50 states on June 14, 2025.

    Lawmakers are intensifying their focus on immigration policy as well. As the Trump administration escalates enforcement, Democratic-led states are expanding laws that limit cooperation with federal agents. On June 12, the House Oversight Committee questioned Democratic governors about these measures, with Republican lawmakers citing public safety concerns. The hearing underscored deep divisions between federal and state approaches to immigration enforcement.

    The legacy of Black witnessing

    What’s unfolding now is not new – it is newly visible. As my research shows, Latino organizers are drawing from a playbook that was sharpened in 2020 and rooted in a much older lineage of Black media survival strategies that were forged under extreme oppression.

    In my 2020 book “Bearing Witness While Black: African Americans, Smartphones and the New Protest Journalism,” I document how Black Americans have used media – slave narratives, pamphlets, newspapers, radio and now smartphones – to fight for justice. From Frederick Douglass to Ida B. Wells to Darnella Frazier, Black witnesses have long used journalism as a tool for survival and transformation.

    Latino mobile journalists are building on that blueprint in 2025, filming state power in moments of overreach, archiving injustice in real time, and expanding the impact of this radical tradition.

    Their work also echoes the spatial tactics of Black resistance. Just as enslaved Black people once mapped escape routes during slavery and Jim Crow, Latino communities today are engaging in digital cartography to chart ICE-free zones, mutual aid hubs and sanctuary spaces. The People Over Papers map channels the logic of the Black maroons – communities of self-liberated Africans who escaped plantations to track patrols, share intelligence and build networks of survival. Now, the hideouts are digital. The maps are crowdsourced. The danger remains.

    Likewise, the Stop ICE Raids Alerts Network revives a civil rights-era tactic. In the 1960s, organizers used wide area telephone service lines and radio to circulate safety updates. Black DJs cloaked dispatches in traffic and weather reports – “congestion on the south side” signaled police blockades; “storm warnings” meant violence ahead. Today, the medium is WhatsApp. The signal is encrypted. But the message – protect each other – has not changed.

    Layered across both systems is the DNA of the “Negro Motorist Green Book,” the guide that once helped Black travelers navigate Jim Crow America by identifying safe towns, gas stations and lodging. People Over Papers and Stop ICE Raids are digital descendants of that legacy. Where the Green Book used printed pages, today’s tools use digital pins. But the mission remains: survival through shared knowledge, protection through mapped resistance.

    The People Over Papers map is a crowdsourced collection of reports of ICE activity across the U.S.

    Dangerous necessity

    Five years after George Floyd’s death, the power of visual evidence remains undeniable. Black witnessing laid the groundwork. In 2025, that tradition continues through the lens of Latino mobile journalists, who draw clear parallels between their own community’s experiences and those of Black Americans. Their footage exposes powerful echoes: ICE raids and overpolicing, border cages and city jails, a door kicked in at dawn and a knee on a neck.

    Like Black Americans before them, Latino communities are using smartphones to protect, to document and to respond. In cities such as Chicago, Los Angeles and El Paso, whispers of “ICE is in the neighborhood” now flash across Telegram, WhatsApp and Instagram. For undocumented families, pressing record can mean risking retaliation or arrest. But many keep filming – because what goes unrecorded can be erased.

    What they capture are not isolated incidents. They are part of a broader, shared struggle against state violence. And as long as the cameras keep rolling, the stories keep surfacing – illuminated by the glow of smartphone screens that refuse to look away.

  • MIL-OSI Submissions: Metro Detroit is growing – but its suburbs are telling a more complicated story

    Source: The Conversation – USA – By Grigoris Argeros, Professor of Sociology, Eastern Michigan University

    Following decades of population loss, Detroit may finally be turning a corner.

    According to the U.S. Census Bureau’s most recent estimates, the city saw an increase in population for both 2023 and 2024.

    An additional 11,000 people moved into the city in the years 2023 and 2024, a small gain in a city with a population of 645,705 – but one which marked a symbolic shift.

    The census data shows just over 1% growth in the past year alone and 0.7% the year before compared with a nearly 25% loss between 2000 and 2010.

    As an urban sociologist studying issues related to race and ethnicity, I am interested in how Detroit’s population is changing, and where different groups live in both the city and its suburbs.

    Analyzing population trends in the metro Detroit area using data from the U.S. Census Bureau, I wanted to understand how racial, ethnic and socioeconomic trends are unfolding, and what those changes can tell us about the evolution and vitality of Detroit.

    Black Detroiters relocate, city diversifies

    From 2010 to 2023, Detroit’s racial and ethnic makeup continued to gradually diversify even as the city was declining in population.

    While Black residents are still the majority, their proportion of the total number fell from around 84% to 79%.

    Other groups, in contrast, increased their share of the city’s population. Between 2010 and 2023, the percentage of Hispanic residents grew from 6.6% to 8.3%, the percentage of white residents grew from 8.2% to 10.7%, and the percentage of Asian residents grew from 1.3% to 1.7%.

    These shifts reflect a steady and ongoing diversification of Detroit’s population, indicative of new migration trends and shifting neighborhood dynamics.

    Suburbs in flux

    In addition to Detroit’s recent population growth, a broader story is unfolding in the city’s suburbs.

    The population of the suburban area as a whole increased 0.73% from 2023 to 2024, but growth was not evenly spread. Collectively, the outer-ring suburbs gained almost 20,000 people, increasing by 1%. Communities such as the city of Troy and Macomb Township accounted for a significant share of that growth.

    Inner-ring suburbs, such as Southfield, Warren and others, grew less vigorously – gaining just 4,000 people, or 0.31%.

    These differences highlight the necessity of complicating the conventional city-versus-suburb narrative to acknowledge the many economic and racial divisions across the metropolitan region.

    The socioeconomic statuses of residents of the inner- and outer-ring suburbs diverged between 2000 and 2020.

    My analysis of census data shows that although both subregions witnessed increases in median household incomes, the rates of change were significantly higher in the outer-ring suburbs, with a 37.7% increase versus a 16.8% increase in the inner rings.

    The data shows a similar trend in higher education attainment. Outer ring suburbs gained 7.1% more residents with college degrees or higher during this period, while the inner suburbs lost 7.5%.

    Homeownership patterns in the two suburban regions also diverged over those two decades, increasing 18% in the outer rings and decreasing 10% in the inner rings.

    The data on poverty and immigration also reveal contrasting results.

    According to my calculations of census data, inner-ring suburbs experienced a 77% increase in poverty, while the outer ring experienced a lesser, though considerable, 50.8% bump in poverty during the 2000-2020 period.

    Meanwhile, during the same time period, the foreign-born populations in the outer suburbs expanded by 24.9%, with increases of at least 10,000 in places such as Sterling Heights, Novi and Canton. In contrast, the inner suburbs saw more modest gains — around 5,000 in cities such as Dearborn Heights and Warren — while their overall foreign-born share declined by nearly 20%.

    Together, the above trends highlight the necessity of not viewing the suburban area as a monolith. These patterns reflect national trends, in which many older, inner-ring suburbs are experiencing socioeconomic stagnation or decline while newer, outer-ring suburbs continue to attract more people who have higher incomes.

    Mixed neighborhoods grow

    Residential segregation also differentiates inner and outer suburban rings.

    Segregation levels remain high in the inner suburbs, especially between white and Black residents. While outer suburbs tend to be more integrated today, the rate of change there has been more modest over the past two decades.

    Social scientists measure segregation using a tool called the “dissimilarity index.” The index represents the proportion of one group that would need to move to establish an equal distribution of the population based on their relative numbers. It ranges from 0 to 100. A score of 0 means equal distribution across neighborhoods, while a score of 100 means the two groups live in completely separate areas.

    From 2000 to 2020, white-Black segregation across the region decreased from 84.4% to 68.3% on the index, while white-Hispanic segregation decreased from 47.6% to 39.9%. Together, these numbers indicate a broader trend toward more integrated living patterns.

    In the inner-ring suburbs, segregation fell across the board. White-Black segregation went down by 15.6%; white-Asian and white-Hispanic segregation dropped even more, by 43.2% and 30.7%, respectively.

    These trends suggest that while the outer suburbs currently have lower levels of segregation, the inner suburbs are integrating more rapidly, reflecting shifting patterns of neighborhood change and increasing racial and ethnic diversity.

    Detroit has come a long way since exiting bankruptcy in 2014. Its recent population growth and increasing diversity show important signs of renewal.

    In the early hours of June 22, 2025, local time, the United States attacked three nuclear facilities in Iran with “bunker buster” bombs and Tomahawk missiles.

    Following more than a week of Israeli strikes on various targets in Iran – which had prompted retaliatory strikes from Tehran – the U.S. move marks a possible inflection point in the conflict. In initial comments on the strikes at the Fordo, Isfahan and Natanz facilities, President Donald Trump said that Iran’s nuclear program had been “completely and fully obliterated.” In response, Iran’s Foreign Minister Abbas Araghchi said the U.S. had “crossed a very big red line.”

    The Conversation U.S. turned to Javed Ali, an expert on Middle East affairs at the University of Michigan and a former senior official at the National Security Council during the first Trump administration, to talk through why Trump chose now to act and what the potential repercussions could be.

    What do we know about the nature and timing of US involvement?

    President Trump has been forcefully hinting for days days that such a strike could happen, while at the same time opening up a window of negotiation by suggesting as late as June 20 that he would make a decision “within the next two weeks.” We know Trump can be very unpredictable, but he must have assessed that the current conditions presented an opportunity for U.S. action.

    Trump met with the National Security Council twice in the days leading up to the strike. Typically at such meetings the president is presented with a menu of military options, which usually boil down to three: a narrow option, a middle ground and a “if you really want to go big” strike.

    The one he picked, I would argue, is somewhere between the narrow option and the middle ground one.

    The “go big” options would have been an attack on nuclear sites and Iranian leadership – be that senior members of Iran’s Revolutionary Guard, or possibly the Supreme Leader Ayatollah Ali Khamenei. The more narrow approach would have been just one facility, likely to have been Fordo – a deeply fortified uranium enrichment site buried within a mountain.

    What did occur was a strike there, but also at two other sites – Isfahan and Natanz.

    U.S. military chiefs confirmed that that 12 GBU-57s – the so-called 30,000-pound bunker busters – were dropped by B-2 bombers on Fordo, and two on Isfahan.

    That suggests to me that the military goal of the operation was to destroy Iran’s ability to produce and or store highly enriched uranium in a one-time strike rather than drag the U.S. into a more prolonged conflict.

    Has the strike achieved Trump’s objectives?

    It will take some time to properly assess the extent to which Iran’s ability to produce or store highly enriched uranium has been damaged.

    Certainly we know that the bombs hit their targets, and they have been damaged – but to what extent is not immediately clear. General Dan Caine, chairman of the Joint Chiefs of Staff, said that all three target sites had suffered “extremely severe damage and destruction” – possibly rolling back from Trump’s “fully obliterated” assessment. Perhaps most tellingly, Iran has not commented yet on the extent of the damage.

    But to Trump, the objective was not just military but political, too. Trump has long said “no” to a nuclear Iran while at the same time has expressed that he has no desire to drag the U.S. into another war.

    And this strike may allow Trump to achieve those seemingly contradictory goals. If U.S. initial assessments are correct, Iran’s nuclear program will have been severely compromised. But the strikes won’t necessarily pull U.S. into the conflict fully – unless Iran retaliates in such a way that necessitates further U.S. action.

    And that is what Iran’s supreme leader and his military generals will need to work out: Should Iran retaliate and, if so, is it prepared to deal with a heavier U.S. military response – especially when there is no end in sight to its current conflict with Israel.

    What options does Iran have to retaliate against US?

    Iran has in the past tried to respond proportionately to any attack. But here is the problem for Iran’s leaders: There is no feasible proportionate response to the United States. Iran has no capability to hit nuclear plants in the U.S. – either conventionally or through unconventional warfare.

    But there are tens of thousands of U.S. troops in the region, stationed in Iraq, Syria, the United Arab Emirates, Oman, Qatar and Jordan. All are in range of Iran’s ballistic, drones or cruise missiles.

    But that military inventory has been depleted – both by using ballistic missiles in waves of attacks against Israel and by Israel hitting missile launch and storage sites in Iran.

    Similarly, Tehran’s capacity to respond through one of its proxy or aligned groups in the region has been degraded. Hezbollah in Lebanon and Gaza’s Hamas – both of whom have ties to Iran – are in survival mode following damaging attacks from Israel over the past 18 months.

    The Houthis in Yemen are in many ways the “last man standing” in Iran’s so-called “Axis of Resistance.” But the Houthis have limited capability and know that if they do attack U.S. assets, they will likely get hit hard. During Operation Rough Rider from March to May this year, the Trump administration launched over 1,000 strikes against the Houthis.

    Meanwhile Shia militias in Iraq and Syria that could be encouraged to attack U.S. bases haven’t been active in months.

    Of course, Iran could look outside the region. In the past the country has been involved in assassinations, kidnappings and terror attacks abroad that were organized through its Quds Force or via operatives of MOIS, its intelligence service.

    But for Iran’s leaders, it is increasingly looking like a lose-lose proposition. If they don’t respond in a meaningful way, they look weak and more vulnerable. But if they do hit U.S. targets in any meaningful way, they will invite a stronger U.S. involvement in the conflict, as Trump has warned.

    The parallel I see here is with the killing of Iranian general and commander of the Quds Force, Qassem Soleimani, in January 2020 by a U.S. drone strike.

    On that occasion, Iran promised a strong retaliation. Its retaliatory attack against the U.S. Ain al-Asad air base in Iraq involved 27 ballistic missiles and caused the physical destruction of some of the facilities on base as well as traumatic brain injury-type symptoms to dozens of troops and personnel, but no deaths. Nevertheless, after this both the U.S. and Iran then backed off from deepening the conflict.

    The circumstances now are very different. Iran is already at war with Israel. Moreover, the U.S. went after Iran’s crown jewels – its nuclear program – and it was on Iranian territory. Nonetheless, Khameini knows that if he retaliates, he risks provoking a larger response.

    Trump suggested ‘further attacks’ could occur. What could that entail?

    The U.S. has suggested that it has the intelligence and ability to hit senior leadership in Iran. And any “go big option” would have likely involved strikes on key personnel. Similarly there could be plans to hit the Iranian economy by attacking oil and gas targets.

    But such actions risk either damaging the global economy or drawing the U.S. deeper into the conflict – it would evolve from a “one and done” strike to a cycle of attacks and responses. And that could widen political cracks between hawks in the administration and parts of Trump’s MAGA faithful who are against the U.S. being involved in overseas wars.

    Is there any opportunity of a return to diplomacy?

    Trump has not closed his “two weeks” window for talks – theoretically it is still open.

    But will Iran come to table? Leaders there had already said they were not willing to entertain any deal while under attack from Israel. Araghchi, Iran’s foreign minister, said after the U.S. strikes that the time for diplomacy had now passed.

    In any event, you have to ask, what can Iran come to the table with? Do they have much of a nuclear program anymore? And if not, what would they try to negotiate? It would seem, using one of Trump’s phrases, they “don’t have the cards” to make much of a deal.

  • MIL-OSI Submissions: The sleeper Supreme Court decision that could have profound impacts on the Trump administration agenda – and restore faith in the high court

    The American public’s trust in the Supreme Court has fallen precipitously over the past decade. Many across the political spectrum see the court as too political.

    This view is only strengthened when Americans see most of the justices of the court dividing along ideological lines on decisions related to some of the most hot-button issues the court handles. Those include reproductive rights, voting rights, corporate power, environmental protection, student loan policy, worker rights and LGBTQ+ rights.

    But there is one recent decision where the court was unanimous in its ruling, perhaps because its holding should not be controversial: National Rifle Association v. Vullo. In that 2024 case, the court said that it’s a clear violation of the First Amendment’s free speech provisions for government to force people to speak and act in ways that are aligned with its policies.

    The second Trump administration has tried to wield executive branch power in ways that appear to punish or suppress speech and opposition to administration policy priorities. Many of those attempts have been legally challenged and will likely make their way to the Supreme Court.

    The somewhat under-the-radar – yet incredibly important – decision in National Rifle Association v. Vullo is likely to figure prominently in Supreme Court rulings in a slew of those cases in the coming months and years, including those involving law firms, universities and the Public Broadcasting Service.

    That’s because, in my view as a legal scholar, they are all First Amendment cases.

    Will the Supreme Court continue to protect free speech rights, as it did unanimously in 2024?

    Why the NRA sued a New York state official

    In May 2024, in an opinion written by reliably liberal Sonia Sotomayor, a unanimous court ruled that the efforts of New York state government officials to punish companies doing business with the NRA constituted clear violations of the First Amendment.

    Following its own precedent from the 1960s, Bantam Books v. Sullivan, the court found that government officials “cannot attempt to coerce private parties in order to punish or suppress views that the government disfavors.”

    Many of the current targets of the Trump administration’s actions have claimed similar suppression of their First Amendment rights by the government. They have fought back, filing lawsuits that often cite the National Rifle Association v. Vullo decision in their efforts.

    To date, the most egregious examples of actions that violate the principles announced by the court – the executive orders against law firms – have largely been halted in the lower courts, with those decisions often citing what’s now known as the Vullo decision.

    While these cases may still be working their way through the lower courts, it is likely that the Supreme Court will ultimately consider legal challenges to the Trump administration’s efforts in a range of areas.

    These would include the executive orders against law firms, attempts to cut government grants and research funding from universities, potential moves to strip nonprofits of their tax-exempt status, and regulatory actions punishing media companies for what the White House believes to be unfavorable coverage.

    The court could also hear disputes over the government terminating contracts with a family of companies that provides satellite and communications support to the U.S. government generally and the military in particular.

    Despite the variety of organizations and government actions involved in these lawsuits, they all can be seen as struggles over free speech and expression, like Vullo.

    Whether it is private law firms, multinational corporations, universities or members of the media, all have one thing in common: They have all been targeted by the Trump administration for the same reason – they are engaged in actions or speech that is disfavored by President Donald Trump.

    Protecting speech, regardless of politics

    The NRA, an often-controversial gun-rights advocacy organization, was the plaintiff in the Vullo decision.

    But just because the groups that have been targeted by the Trump administration are across the political divide from the NRA does not mean the outcome in decisions relying on the court’s opinion will be different. In fact, these groups can rely on the same arguments advanced by the NRA, and are, I believe, likely to win.

    Vullo isn’t the only decision on which the court can rely when considering challenges to the Trump administration’s efforts targeting these groups.

    In 1943, Supreme Court Justice Robert Jackson wrote the majority opinion in West Virginia State Board of Education v. Barnette, where the court found that students who refused to salute the American flag and recite the Pledge of Allegiance at school could not be expelled.

    Jackson’s opinion is a forceful rejection of government attempts to control what people say: “If there is any fixed star in our constitutional constellation, it is that no official, high or petty, can prescribe what shall be orthodox in politics, nationalism, religion, or other matters of opinion or force citizens to confess by word or act their faith therein.”

    In the wake of World War II, Jackson took a leave from the court and served as a prosecutor in the Nuremberg trials of Nazi leaders. Prosecuting them for their atrocities, Jackson saw how the Nuremberg defendants wielded government authority to punish enemies who resisted their rise and later opposed their rule.

    If some of the cases testing the state’s power to force fidelity to the executive branch reach the Supreme Court, the cases could offer the justices the opportunity to, once again, speak with one voice as they did in NRA v. Vullo, to demonstrate it can be evenhanded and will not play politics with the First Amendment.

    This story has been updated with the correct year for the Supreme Court’s decision in West Virginia State Board of Education v. Barnette.

  • MIL-OSI Submissions: Presidents of both parties have launched military action without Congress declaring war − Trump’s bombing of Iran is just the latest

    Source: The Conversation – USA – By Sarah Burns, Associate Professor of Political Science, Rochester Institute of Technology

    In the wake of the U.S. strikes on Iranian nuclear facilities on June 22, 2025, many congressional Democrats and a few Republicans have objected to President Donald Trump’s failure to seek congressional approval before conducting military operations.

    They note that Article 1 of the U.S. Constitution gives Congress the power to declare war and say that section required Trump to seek prior authorization for military action.

    The Trump administration disagrees. “This is not a war against Iran,” Secretary of State Marco Rubio told Fox News host Maria Bartiromo, implying that the action did not require approval by Congress. That’s the same view held by most modern presidents and their lawyers in the Office of Legal Counsel: Article 2 of the Constitution allows the president to use the military in certain situations without prior approval from Congress.

    By this reading of the text, presidents, as commander in chief, claim the power to unilaterally order the military to initiate small-scale operations for a short duration. Members of Congress may object to that claim, but they have done little to limit presidents’ unilateralism. What little they have done has not been effective.

    As I’ve demonstrated in my research, even though the 1973 War Powers Resolution attempted to constrain presidential power after the disasters of the Vietnam War, it contains many loopholes that presidents have exploited to act unilaterally. For example, it allows presidents to engage in military operations without congressional approval for up to 90 days. And more recent congressional resolutions have broadened executive control even further.

    A long tradition of executive authority

    Presidents can even overcome the loopholes in the War Powers Resolution if the operation lasts longer than 90 days. In 2011, a State Department lawyer argued that airstrikes in Libya could continue beyond the War Powers Resolution’s 90-day time limit because there were no ground troops involved. By that logic, any future president could carry out an indefinite bombing campaign with no congressional oversight.

    While every president has bristled at congressional restraints on their actions, presidents since Franklin D. Roosevelt have successfully circumvented them by citing vague concerns like “national security,” “regional security” or the need to “prevent a humanitarian disaster” when launching military operations. While members of Congress always take issue with these actions, they never hold presidents accountable by passing legislation restraining him.

    President Trump’s decision to bomb Iranian nuclear sites without consulting Congress falls in line with precedent from both Democratic and Republican leaders for decades.

    Much like his predecessors, Trump did not, and likely will not, provide Congress with more concrete information about the legality of his actions. Nor are congressional lawmakers effectively holding him accountable.

    The push-and-pull between Congress and the president over military operations dates back to the 1941 Pearl Harbor attack, which led Congress to declare war on Japan. Before then, Congress had prevented the U.S. from joining World War II by enforcing an arms embargo and refusing to help the Allies prior to the attack on Hawaii. But afterward, Congress began allowing the president to take more control over the military.

    During the Cold War, rather than returning to a balanced debate between the branches, Congress continued to relinquish those powers.

    Congress never authorized the war in Korea; Harry Truman used a U.N. Security Council resolution as legal justification. Congress’ vote explicitly opposing the invasion of Cambodia didn’t stop Richard Nixon from doing it anyway. Even after the Cold War, Bill Clinton regularly acted unilaterally to address humanitarian crises or the continued threat from leaders like Saddam Hussein. He sent the military to Somalia, Haiti, Bosnia and Kosovo, among other places.

    After 9/11, Congress quickly gave up more of its power. A week after those attacks, Congress passed a sweeping Authorization for Use of Military Force, giving the president permission to “use all necessary and appropriate force against those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001.”

    In a follow-up 2002 authorization, Congress went even further, allowing the president to “use the Armed Forces … as he determines to be necessary and appropriate in order to defend national security … against the continuing threat posed by Iraq.” This approach provides few, if any, congressional checks on the control of military affairs exercised by the president.

    In the two decades since those authorizations, four presidents have used them to justify all manner of military action, from targeted killings of terrorists to the years long fight against the Islamic State group.

    Congress regularly discusses terminating those authorizations, but has yet to do so. If Congress did, the loopholes in the original War Powers Resolution would still exist.

    While President Biden claimed he supported the repeal of the authorizations, and supported more congressional oversight of military actions, Trump has made no such claims. Instead, he has claimed even more sweeping authority to act without any permission from Congress.

    As recently as 2024, Biden used the 2002 authorization as a legal rationale for the targeted killing of Iranian-backed militiamen in Iraq, a strike condemned by Iraqi leaders.

    Those actions may have ruffled congressional feathers, but they were in keeping with a long U.S. tradition of targeting members of terrorist groups and protecting members of the military serving in a conflict zone.

    Threats of war

    During his first presidential term in 2020, Trump ordered a lethal drone strike against a respected member of the Iranian government, Major General Qassim Soleimani, the head of Iran’s equivalent of the CIA, without consulting Congress or publicly providing proof of why the attack was necessary, even to this day.

    Tensions – and fears of war – spiked but then slowly faded when Iran responded with missile attacks on two U.S. bases in Iraq.

    Now, the U.S. attacks on Iranian nuclear sites have revived both fears of war and renewed questions about the president’s authority to unilaterally engage in military action. Presidents since the 1970s, however, have effectively managed to dodge definitive answers to those questions – demonstrating both the power inherent in their position and the unwillingness among members of the legislative branch to reclaim their coequal status.

  • MIL-OSI Submissions: Rethinking engineering education: Why focusing on learning preferences matters for diversity

    Source: The Conversation – USA (2) – By Sharon Tettegah, Professor of Creative Studies, University of California, Santa Barbara

    Retention and recruitment efforts designed to boost diversity in engineering programs often fall short of their goals. gorodenkoff/Getty Images

    For decades, colleges, government agencies and foundations have experimented with recruitment and retention efforts designed to increase diversity in engineering programs.

    However, the efforts have not significantly boosted the number of women, students of color, individuals with disabilities and other underrepresented groups studying and earning degrees in STEM and engineering fields.

    Latino, Black, Native American and Alaska Native students are underrepresented among science and engineering degree recipients at the bachelor’s degree level and above. The groups are also underrepresented among STEM workers with at least a bachelor’s degree.

    Women are also underrepresented in the STEM workforce and among degree recipients in engineering and computer and information sciences.

    I study equity and social justice in STEM learning. In my recent study, I found that more students from diverse backgrounds could excel in engineering programs if course content were tailored to a wider variety of learning preferences.

    Why it matters

    Focusing on learning preferences could boost diversity in engineering courses and careers.
    Morsa Images/Getty Images

    During my time as a program officer at the National Science Foundation, an independent federal agency that supports science and engineering, I reviewed plenty of research focused on broadening participation and diversifying student enrollment in STEM fields.

    Progress can stall on efforts to boost diversity because college instructors do not consider the synergistic relationship between the content and the learner.

    Teachers are the mediators, and it is students’ experiences with the curriculum that matter.

    It was long a common belief that students have different learning styles. These included kinesthetic, learning through hands-on experiences and physical activity; auditory, learning by listening to information; and visual, learning by seeing information.

    More recent research does not support the idea that teaching students according to their learning style leads to improved learning.

    That’s why I prefer the term “learning preferences” rather than learning styles. We all have preferences – whether for ice cream flavors, home decor or how we receive information, including how we learn.

    Learning preferences are broader and more flexible, allowing multiple ways of engaging with content.

    For example, let’s say a teacher always presented equations in a classroom and the student just could not get it. However, it was the only way the information was presented. To the individual learner, they have failed. Some people would say, “These kids can’t learn,” and subsequently counsel the student out of the class.

    Then, years are spent repeating the same cycle.

    Students should have opportunities to connect with engineering content in multiple ways.
    10’000 hours/Getty Images

    However, educators can broaden their viewpoints if they look at the students as customers. If a customer is shopping for a shirt, they look for one that catches their eye. Ultimately, they find one they like.

    Instructors need to take the same approach when trying to help students understand what is happening in class. For instance, if I have trouble with equations, I should be provided with options to engage with the lesson in ways that align with my learning preferences.

    What’s next?

    Learning styles have been heavily researched. However, content preferences have not been well explored.

    In a truly democratic education system, curriculum design should reflect the voices of all stakeholders and not just those in positions of power, namely instructors.

    Using data mining and artificial intelligence, educators have a variety of options for creating content for the various preferences a learner may want or need. For example, if a student prefers other representational content, such as word problems, graphics or simulations, AI can create diverse representations so that the learner is exposed to a variety of representations.

    I argue that future studies need to consider the use of technologies such as adaptive learning applications to understand students’ learning preferences.

    Prioritizing diverse learning perspectives in STEM could help create a more inclusive and responsive learning environment.

    The Research Brief is a short take on interesting academic work.

  • MIL-OSI Submissions: Harvard fights to keep enrolling international students – 4 essential reads about their broader impact

    Source: The Conversation – USA (2) – By Corey Mitchell, Education Editor

    A federal judge in Boston on May 23, 2025, temporarily blocked a Trump administration order that would have revoked Harvard University’s authorization to enroll international students.

    The directive from the U.S. Department of Homeland Security and resulting lawsuit from Harvard have escalated the ongoing conflict between the Trump administration and the Ivy League institution.

    It’s also the latest step in a White House campaign to ramp up vetting and screening of foreign nationals, including students.

    Homeland Security officials accused Harvard of creating a hostile campus climate by accommodating “anti-American” and “pro-terrorist agitators.” The accusation stems from the university’s alleged support for certain political groups and their activities on campus.

    In early April, the Trump administration terminated the immigration statuses of thousands of international students listed in a government database, the Student and Exchange Visitor Information System. The database includes country of citizenship, which U.S. school they attend and what they study.

    Barring Harvard from enrolling international students could have significant implications for the campus’s climate and the local economy. International students account for 27% of the university’s enrollment.

    Here are four stories from The Conversation’s archive about the Trump administration’s battle with Harvard and the economic impact of international students.

    1. A target on Harvard

    This isn’t the first time the Trump administration has targeted the university.

    The White House has threatened to end the university’s tax-exempt status, and some media outlets have reported that the Internal Revenue Service is taking steps in that direction.

    But it is illegal to revoke an entity’s tax-emempt status “on a whim,” according to Philip Hackney, a University of Pittsburgh law professor, and Brian Mittendorf, an accounting professor at Ohio State University.

    “Before the IRS can do that, tax law requires that it first audit that charity,” they wrote. “And it’s illegal for U.S. presidents or other officials to force the IRS to conduct an audit or stop one that’s already begun.”

    Several U.S. senators, all Democrats, have urged the IRS inspector general to see whether the IRS has begun auditing Harvard or any nonprofits in response to the administration’s requests or whether Trump has violated any laws with his pressure campaign.

    Hackney and Mittendorf wrote that the Trump administration’s moves are part of a larger push to exert control over Harvard, including its efforts to increase its diversity and its response to claims of discrimination on campus.

    2. International students help keep ‘America First’

    The U.S. has long been the global leader in attracting international students. But competition for these students is increasing as other countries vie to attract the scholars.

    In a recent story for The Conversation, David L. Di Maria, vice provost for global engagement at the University of Maryland, Baltimore County, wrote that stepped-up screening and vetting of students could make the U.S. a less attractive study destination.

    Di Maria wrote that such efforts could hamper the Trump administration’s ability to achieve its “America First” priorities related to the economy, science and technology, and national security.

    Trump administration officials have emphasized the importance of recruiting top global talent. And Trump has said that international students who graduate from U.S. colleges should be awarded a green card with their degree.

    Research shows that international students launch successful startups at a rate that is eight to nine times higher than their U.S.-born peers. Roughly 25% of billion-dollar companies in the U.S. were founded by former international students, Di Maria noted.

    3. A boost to local economies

    Indeed, international students have a tremendous economic impact on local communities.

    If these global scholars stay home or go elsewhere, that’s bad economic news for cities and towns across the United States, wrote Barnet Sherman, a professor of multinational finance and trade at Boston University.

    With the money they spend on tuition, food, housing and other other items, international students pump money into the local economy, but there are additional benefits.

    On average, a new job is created for every three international students enrolled in a U.S. college or university. In the 2023-24 academic year, about 378,175 jobs were created, Sherman wrote.

    In Greater Boston, where Harvard is located, there are about 63,000 international students who contribute to the economy. The gains are huge – about US$3 billion.

    4. Rising number of international students

    The rising number of foreign students studying in the U.S. has long led to concerns about U.S. students being displaced by international peers.

    The unease is often fueled by the assumption that financial interests are driving the trend, Cynthia Miller-Idriss of American University and Bernhard Streitwieser of George Washington University wrote in a 2015 story for The Conversation.

    A common claim, they wrote, is the flawed assumption that “cash-strapped public universities” aggressively recruit more affluent students from abroad who can afford to pay rising tuition costs. The pair wrote that, historically, shifting demographics on college campuses result from social and economic changes.

    In today’s context, Miller-Idriss and Streitwieser maintain that the argument that colleges prioritize international students fails to account for the global role of U.S. universities, which help support national security, foster international development projects and accelerate the pace of globalization.

  • MIL-OSI Submissions: Air traffic controller shortages in Newark and other airports partly reflect long, intense training − but university-based training programs are becoming part of the solution

    Air traffic controllers have been in the news a lot lately.

    A spate of airplane crashes and near misses have highlighted the ongoing shortage of air traffic workers, leading more Americans to question the safety of air travel.

    The shortage, as well as aging computer systems, have also led to massive flight disruptions at airports across the country, particularly at Newark Liberty International Airport. The staffing shortage is also likely at the center of an investigation of a deadly crash between a commercial plane and an Army helicopter over Washington, D.C., in January 2025.

    One reason for the air traffic controller shortage relates to the demands of the job: The training to become a controller is extremely intense, and the Federal Aviation Administration wants only highly qualified personnel to fill those seats, which has made it difficult for what has been the sole training center in the U.S., located in Oklahoma City, to churn out enough qualified graduates each year.

    As scholars who study and teach tomorrow’s aviation professionals, we are working to be part of the solution. Our program at Ohio State University is applying to join over two dozen other schools in an effort to train air traffic controllers and help alleviate the shortage.

    Air traffic controller school

    Air traffic control training today – overseen by the Federal Aviation Administration – remains as intense as it’s ever been.

    In fact, about 30% of students fail to make it from their first day of training at the FAA Academy in Oklahoma City to the status of a certified professional air traffic controller. The academy currently trains the majority of the air traffic controllers in the U.S.

    Before someone is accepted into the training program, they must meet several qualifications. That includes being a U.S. citizen under the age of 31 and speaking English clearly enough to be understood over the radio. The low recruitment age is because controllers currently have a mandatory retirement age of 56 – with some exceptions – and the FAA wants them to work for at least 25 years in the job.

    They must also pass a medical exam and security investigation. And they must pass the air traffic controller specialists skills assessment battery, which measures an applicant’s spatial awareness and decision-making abilities.

    Candidates, additionally, must have three years of general work experience, or a combination of postsecondary education and work experience totaling at least three years.

    This alone is no easy feat. Fewer than 10% of applicants meet those initial requirements and are accepted into training.

    Intense training

    Once applicants meet the initial qualifications, they begin a strenuous training process.

    This begins with several weeks of classroom instruction and several months of simulator training. There are several types of simulators, and a student is assigned to a simulator based on the type of facility for which they will be hired – which depends on a trainee’s preference and where controllers are needed.

    There are two main types of air traffic facilities: control towers and radar. Anyone who has flown on a plane has likely seen a control tower near the runways, with 360 degrees of tall glass windows to monitor the skies nearby. Controllers there mainly look outside to direct aircraft but also use radar to monitor the airspace and assist aircraft in taking off and landing safely.

    Radar facilities, on the other hand, monitor aircraft solely through the use of information depicted on a screen. This includes aircraft flying just outside the vicinity of a major airport or when they’re at higher altitudes and crisscrossing the skies above the U.S. The controllers ensure they don’t fly too close to one another as they follow their flight paths between airports.

    If the candidates make it through the first stage, which takes about six months and extensive testing to meet standards, they will be sent to their respective facilities.

    Once there, they again go to the classroom, learning the details of the airspace they will be working in. There are more assessments and chances to “wash out” and have to leave the program.

    Finally, the candidates are paired with an experienced controller who conducts on-the-job training to control real aircraft. This process may take an additional year or more. It depends on the complexity of the airspace and the amount of aircraft traffic at the site.

    Increasing the employment pipeline

    But no matter how good the training is, if there aren’t enough graduates, that’s a problem for managing the increasingly crowded skies.

    The FAA is currently facing a deficit of about 3,000 controllers and has unveiled a plan in May 2025 to increase hiring and boost retention. In addition, Congress is mulling spending billions of dollars to update the FAA’s aging systems and hire more air traffic controllers.

    Other plans include paying retention bonuses and allowing more controllers to work beyond the age of 56. That retirement age was put in place in the 1970s on the assumption that cognition for most people begins to decline around then, although research shows that age alone is not necessarily a predictor of cognitive abilities.

    But we believe that aviation programs and universities can play an important role fixing the shortage by providing FAA Academy-level training.

    Currently, 32 universities including the Florida Institute of Technology and Arizona State University partner with the FAA in its collegiate training initiative to provide basic air traffic control training, which gives graduates automatic entry into the FAA Academy and allows them to skip five weeks of coursework.

    The institution where we work, Ohio State University, is currently working on becoming the 33rd this summer and plans to offer an undergraduate major in aviation with specialization in air traffic control.

    This helps, but an enhanced version of this program, announced in October 2024, allows graduates of a select few of those universities to skip the FAA Academy altogether and go straight to a control tower or radar facility once they’ve passed all the extensive tests. These schools must match or exceed the level of rigor in their training with the FAA Academy itself.

    At the end of the program, students are required to pass an evaluation by an FAA-approved evaluator to ensure that the student graduating from the program meets the same standards as all FAA Academy graduates and is prepared to go to their assigned facility for further training. So far, five schools, such as the University of North Dakota, have joined this program and are currently training air traffic controllers. We intend to join this group in the near future.

    Allowing colleges and universities to start the training process while students are still in school should accelerate the pace at which new controllers enter the workforce, alleviate the shortage and make the skies over the U.S. as safe as they can be.
