    Light is all around us, essential for one of our primary senses (sight) as well as life on Earth itself. It underpins many technologies that affect our daily lives, including energy harvesting with solar cells, light-emitting-diode (LED) displays and telecommunications through fibre optic networks.

    The smartphone is a great example of the power of light. Inside the box, its electronic functionality works because of quantum mechanics. The front screen is an entirely photonic device: liquid crystals controlling light. The back too: white light-emitting diodes for a flash, and lenses to capture images.

    We use the word photonics, and sometimes optics, to capture the harnessing of light for new applications and technologies. Their importance in modern life is celebrated every year on 16 May with the International Day of Light.

    Scientists on the African continent, despite the resource constraints they work under, have made notable contributions to photonics research. Some of these have been captured in a recent special issue of the journal Applied Optics. Along with colleagues in this field from Morocco and Senegal, we introduced this collection of papers, which aims to celebrate excellence and show the impact of studies that address continental issues.

    A spotlight on photonics in Africa

    Africa’s history in formal optics stems back thousands of years, with references to lens design already recorded in ancient Egyptian writings.

    In more recent times, Africa has contributed to two Nobel prizes based on optics. Ahmed Zewail (Egyptian born) watched the ultrafast processes in chemistry with lasers (1999, Nobel Prize for Chemistry) and Serge Harouche (Moroccan born) studied the behaviour of individual particles of light, photons (2012, Nobel Prize for Physics).

    Unfortunately, the African optics story is one of pockets of excellence. The highlights are as good as anywhere else, but there are too few of them to put the continent on the global optics map. According to a 2020 calculation done for me by the Optical Society of America, based on their journals, Africa contributes less than 1% to worldwide journal publications with optics or photonics as a theme.

    Yet there are great opportunities for meeting continental challenges using optics. Examples of areas where Africans can innovate are:

    • bridging the digital divide with modern communications infrastructure

    • optical imaging and spectroscopy for improvements in agriculture and monitoring climate changes

    • harnessing the sun with optical materials for clean energy

    • bio-photonics to solve health issues

    • quantum technologies for novel forms of communicating, sensing, imaging and computing.

    The papers in the special journal issue touch on a diversity of continent-relevant topics.

    One is on using optics to communicate across free-space (air) even in bad weather conditions. This light-based solution was tested using weather data from two African cities, Alexandria in Egypt and Setif in Algeria.

    Another paper is about tiny quantum sources of quantum entanglement for sensing. The authors used diamond, a gem found in South Africa and more commonly associated with jewellery. Diamond has many flaws, one of which can produce single photons as an output when excited. The single photon output was split into two paths, as if the particle went both left and right at the same time. This is the quirky notion of entanglement, in this case, created with diamonds. If an object is placed in any one path, the entanglement can detect it. Strangely, sometimes the photons take the left-path but the object is in the right-path, yet still it can be detected.

    Quantum entanglement: what it is, and why physicists want to harness it

    One contributor proposes a cost-effective method to detect and classify harmful bacteria in water.

    New approaches in spectroscopy (studying colour) for detecting cell health; biosensors to monitor salt and glucose levels in blood; and optical tools for food security all play their part in optical applications on the continent.

    Another area of African optics research that has important applications is the use of optical fibres for sensing the quality of soil and its structural integrity. Optical fibres are usually associated with communication, but a modern trend is to use the existing optical fibre already laid to sense for small changes in the environment, for instance, as early warning systems for earthquakes. The research shows that conventional fibre can also be used to tell if soil is degrading, either from lack of moisture or some physical shift in structure (weakness or movement). It is an immediately useful tool for agriculture, building on many decades of research.

    The diverse range of topics in the collection shows how creative researchers on the continent are in using limited resources for maximum impact. The high orientation towards applications is probably also a sign that African governments want their scientists to work on solutions to real problems rather than purely academic questions. A case in point is South Africa, which has a funded national strategy (SA QuTI) to turn quantum science into quantum technology and train the workforce for a new economy.

    Towards a brighter future

    For young science students wishing to enter the field, the opportunities are endless. While photonics has no discipline boundaries, most students enter through the fields of physics, engineering, chemistry or the life sciences. Its power lies in the combination of skills, blending theoretical, computational and experimental, that are brought to bear on problems. At a typical photonics conference there are likely to be many more industry participants than academics. That’s a testament to its universal impact in new technologies, and the employment opportunities for students.

    The last century was based on electronics and controlling electrons. This century will be dominated by photonics, controlling photons.

  • MIL-OSI Submissions: Virtual churches are popular in Ghana. But what about online safety?

    Source: The Conversation – Africa (2) – By Theodora Dame Adjin-Tettey, Senior Lecturer, Durban University of Technology/Research Associate, School of Journalism and Media Studies, Durban University of Technology

    Many churches have been holding worship services online via live-streaming platforms in recent times. This is unsurprising since many congregants use digital technologies. The COVID-19 pandemic also pushed churches to swiftly embrace digital platforms. This allowed them to continue with religious activities when physical and mobility restrictions were in place.

    Some churches invest heavily in audio-visual equipment, lighting systems and other gadgets to provide the right conditions for media production and to enhance the worship experience for congregants, online and in person.

    Digital technologies and platforms have become core components of the outreach and evangelistic activities of churches. Some contemporary pastors have a strong online presence with a huge following, mostly in the millions. They actively engage their followers and share different forms of messages with them.

    As the amount of online content generated by churches grows, questions of safety, security and privacy have come to the fore. It is important to look at how churches address these concerns as they rapidly deploy digital platforms to reach and maintain virtual church membership.

    I am a media and communication studies academic and researcher. In a recent paper I worked with my student to examined the concerns of congregants of a church in Ghana over the security dangers that digital church engagement poses.

    Christianity is the religion with the largest following in Ghana. During the COVID-19 pandemic, many churches turned to online services and have continued with them.

    The research revealed that there were no established policies guiding the church’s virtual engagements. The media team relied primarily on their subjective judgement to address any potential ethical dilemmas.

    Beside enhanced privacy measures and access control, we recommend ethical frameworks and guidelines to govern the management of congregants’ personal information in both physical and virtual environments. This must include the inputs of congregants and experts.

    The research also found that word of mouth was still the primary means by which congregants came to learn about the church. This suggests churches cannot abandon the old ways of reaching out to people.

    Digital technology and the church

    Radio, TV and social media are all used to extend invitations to the public, promote and advertise churches, and generally facilitate church activities. The importance of having an online presence has compelled a significant number of churches to have dedicated media teams. They create and distribute content meant for digital platforms. The content includes photos and audiovisual testimonies of church members.

    To ensure that members of online churches have a positive experience during live streaming, most media departments also invest creativity into their videography. On live streams, followers (virtual congregants) react to songs being sung and respond to what the preacher says with comments and the use of emojis and GIFs. This is synonymous with how they might react in the physical church environment.

    But during the streaming of worship services, information about church members is not just shared in the physical church environment but also with a broader online audience. By the nature of live-streaming, there is no control over who has access to the content, how widely it is distributed, and for what and how the content is used by third parties.

    The study and some of its key findings

    Data collection for our study involved 170 survey respondents (congregants) and eight interview participants (videographers, video editors and social media managers from the church media department).

    We asked the congregants how they had first learned about the church; factors influencing their participation in virtual church services; and what safety and security concerns they had around their virtual church engagements.

    The interview participants were asked about the ethical considerations directing their work.

    Our study found that congregants had a range of concerns. Based on the sense of safety, confidence and trust they have in the church, congregants participating in physical church services may divulge personal information. These include prayer requests, personal hardships, or testimonials about their accomplishments. They sometimes do this with the understanding that the information will remain inside the church’s walls.

    Chief among the concerns were:

    • the risk of identity theft

    • the potential misuse of personal data for targeted advertising

    • potential privacy invasion because of their interactions with the church’s digital platforms.

    Some members of the media team admitted that congregants might have privacy and security concerns. However, in the absence of formal guidelines, any attempt to ensure the privacy and security of congregants might be an ad hoc measure. This was demonstrated in the study’s finding that the media team’s privacy and security adherence was largely based on their judgement and sometimes on prodding from congregants.

    What can be done

    Based on concerns raised by congregants, we argue that churches must ensure the privacy of those participating in services by instituting confidentiality and anonymity measures, particularly when sharing their personal or sensitive information.

    In addition, participants in our research held the view that some sensitisation could be useful to cater to those concerns. This could take the form of regular sensitisation of congregants on how they can enhance their online safety and security.

    We believe that because churches sometimes rely on photos, videos and testimonies of members to build their social media profiles, a rule-based system must be put in place. This could involve delayed broadcasting techniques to prevent the airing of sensitive information.

    We suggest that steps be taken to protect sensitive information and content about members that is shared online. An example of how this can be done is being set by a non-denominational prayer movement that has taken over Ghana’s online sphere. To secure the privacy of members who share testimonies, their identities are kept anonymous and certain details, such as names and places, are also protected.

    Finally, the right technology must be put in place to allow for delayed broadcasts. This means live-streamed content can be reviewed and, where necessary, edited so that sensitive content can be removed before the broadcast reaches a wide online audience.

  • MIL-OSI Submissions: Psychology in democratic South Africa: new book explores a post-apartheid journey

    When apartheid ended in 1994, South Africa underwent significant social and political transformation. A key aspect of this shift was the push for greater inclusion and representation of Black South Africans across all sectors – including psychology.

    Dr Liezille Jacobs was part of a pioneering generation of Black psychologists who started their training in 1995. Now she has written a book, Rocklands: On becoming the first generation of Black psychologists in post-apartheid South Africa. In it she explores the barriers she and her colleagues faced and unpacks misconceptions around what psychology is and does. She also argues that critical (and African) psychology can both “address the legacies of apartheid and heal the relational traumas caused by systemic oppression”. The Conversation Africa asked her about the book and her work.

    What is the book about?

    I wrote Rocklands to address the widespread misconceptions that both first-year psychology students and the general public often hold about what it truly means to be a psychologist. It’s common for people to oversimplify the profession. They view it merely as talking to people or offering quick-fix solutions to problems. The reality is far more complex.

    I wanted to challenge these superficial ideas and provide a more layered and accurate representation of the field. The process of becoming a psychologist is not just about acquiring theoretical knowledge. It’s also about developing emotional intelligence, critical thinking, and a strong ethical foundation. Psychologists must balance empathy with objectivity, personal insight with professional boundaries, all while navigating the vast complexities of human emotions, relationships, and societal influences.

    The goal of the book is to make psychological knowledge and expertise more accessible to the public.

    Rocklands is also an account of resilience and personal growth in the face of adversity. The first chapter reflects on my early experiences growing up in Rocklands, Mitchell’s Plain. Rocklands was established during apartheid as part of a government plan to segregate communities. Black South Africans were moved to areas like Mitchell’s Plain under the Group Areas Act. Over time, Rocklands grew into a working-class neighborhood, shaped by its apartheid-era history.

    The ensuing chapters provide a detailed account of my unique and often difficult journey. I’ve traversed a path less travelled but it’s ultimately led to personal and professional fulfilment.

    Why did you decide to study psychology?

    I initially dreamed of becoming a journalist. However, my parents encouraged me to explore other career options. The results of a career assessment suggested I should consider social work, occupational therapy or psychology.

    Psychology truly caught my attention. As someone with an introverted personality I was drawn to the idea of understanding human behaviour and thought processes on a deeper level. At the time, I envisioned myself working as a clinical psychologist, helping individuals one-on-one.

    Everything shifted when I began my formal studies in 1995. I quickly realised that the field of psychology in South Africa – especially in the context of its history – had much more work to do. I saw the gaps in the system and became acutely aware of how psychology had, in many ways, been complicit in perpetuating social injustices. In 1995, as a first year psychology student, I was made aware of the field’s struggle with its apartheid legacy and psychology’s unfinished business.

    Hendrik Verwoerd was the architect of the racist policies and segregation system that became known worldwide as “grand apartheid”. He was also a psychologist by training.

    Psychology in South Africa has made efforts to adapt to a diverse society. But there are still challenges. These include a disconnect between academic training and professional practice, and the lingering effects of apartheid-era inequalities.

    Being black in the world: a tribute to pioneering South African psychologist Chabani Manganyi

    South Africa desperately needed (and still does today) Critical Psychologists. Critical psychology challenges traditional psychological theories by examining the social, political, and historical contexts that shape psychological issues. It critiques mainstream psychology for overlooking power structures. And it aims to use psychology as a tool for social change and addressing inequalities.

    Critical psychologists challenge the dominant narratives of the past, address the legacies of apartheid, and have access to the tools to heal the relational traumas caused by systemic oppression. I knew I wanted to contribute to the transformation of the profession – to make it more inclusive, socially responsible, and oriented towards healing the wounds left by historical injustices. This shift in perspective has shaped my entire career. It’s guided my studies, research and teaching practice.

    Have South Africa’s universities changed how they teach psychology?

    The academic transformation project continues and universities are striving to adapt to a more diverse student body. But the pace and extent of this change can vary between institutions.

    There has been a growing recognition globally that psychology, as a discipline, needs to move beyond its traditional western-centric, individualistic frameworks. It must engage more deeply with local contexts and diverse ways of knowing and experiencing the world.

    I was the head of the Psychology Department at Rhodes University in South Africa’s Eastern Cape province from 2022 to 2024. The department has incorporated indigenous knowledge systems such as African philosophical perspectives and non-western psychological practices into our teaching.

    For example, community-based service-learning strategies are emphasised in the undergraduate courses I teach. Community-based service-learning combines community service with academic learning. This gives students the opportunity to engage in real-world problems and contribute to the community while applying psychological theories, concepts and methods. Students learn how to become engaged citizens.

    We also use a variety of teaching materials – case studies, texts by African scholars, multimedia – that resonate with students’ lived experiences.

    Decolonising psychology creates possibilities for social change

    In a society as culturally and racially diverse as South Africa it is crucial for people to see themselves reflected in the professionals they turn to for help. This can play a role in lowering barriers to mental health services.

    South Africa has a legacy of collective struggle and community resilience. Psychology stands to gain from a greater understanding of collective identities, community dynamics and social justice. Psychologists from diverse backgrounds can offer more nuanced, holistic interventions that address systemic issues rather than focusing solely on individual pathology.

  • MIL-OSI Submissions: Life after school for young South Africans: six insights into what lies ahead

    Source: The Conversation – Africa – By Gabrielle Wills, Senior researcher at Research on Socio-Economic Policy, Stellenbosch University

    Matric exams are a crucial moment in a young person’s educational journey. Fani Mahuntsi/Gallo Images via Getty Images

    At the dawn of democracy in 1994, South Africa faced a sobering reality. Fewer than a third of 25- to 34-year-olds had achieved at least a matric (12 years of schooling completed) or equivalent qualification.

    Thirty years on, the proportion of individuals in this age group that had completed their schooling had almost doubled to 57%. This figure will be further bolstered by the record-breaking results in the National Senior Certificate (matric) examinations in recent years. South Africa’s school completion rates are now high and comparable to other middle-income countries.

    But this good news is tempered by very high youth unemployment and a faltering economy. What are the prospects for young South Africans once they’ve matriculated?

    I have aimed to answer this question in my new study. By using the Quarterly Labour Force Survey – a nationally representative, household-based sample survey – and other data sources, I have developed six insights that tell us what the post-matric landscape is like today. For the purposes of the study I defined recent matriculants as 15-24-year-olds with 12 years of completed schooling.

    This study highlights how increasingly larger proportions of recent matriculants find they have limited opportunities. The rising number of youth leaving school with a matric, especially in recent years, is not being met with enough opportunities beyond school, whether in work or in post-school education and training.

    Conditions in South Africa’s labour market must improve and further expansion in quality post-school education and training is required for the country to realise the benefits of rising educational attainment and progress for national development.

    1. Less chance of employment

    The graph below illustrates a brutal truth: ten years ago finding a job was easier for matriculants than it will be for the matric class who finished school in 2024. Between 2014 and 2018 about 4 of every 10 recent matriculants who were economically active (including discouraged work seekers) were employed. By the start of 2024 this figure was closer to 3 of every 10.

    Percent of South African youth employed by qualification level.
    Dr Gabrielle Wills, CC BY-NC-ND

    The likelihood of youth with a matric having a job at the start of 2024 roughly resembled the chances of youth without a matric having a job eight to ten years ago.

    With more learners progressing to matric, especially due to more lenient progression policy during and just after the COVID-19 pandemic, changes in the composition of the matric group could be driving some of the declines in this group’s employment prospects. But there has been a deterioration in the labour market for all youth over the past decade. Employment prospects have even declined for youth with a post-school qualification.

    2. Not in employment, education or training

    Proportionally fewer recent matriculants are going on to work or further study.

    Before the COVID-19 pandemic (2014-2019), around 44%-45% of recent matriculants were classified as “not in employment, education or training” (NEET). The NEET rate among recent matriculants peaked at 55% in early 2022 and remained high at 49.8% at the start of 2024.

    Stated differently, one of every two recent matriculants was not engaged in work or studies in the first quarter of last year. That’s 1.78 million individuals. Coupled with the rising numbers of youth getting a matric, this implies that the number of recent matriculants who were not working or studying rose by half a million from the start of 2015 to the start of 2024.

    Among all 15-24-year-olds, the NEET rate rose from 32% in the first quarter of 2014 to 35% in the first quarter of 2024. Even larger increases in the NEET rate occurred among 25-34-year-olds, rising from 45% to 52% over the same period.

    This is a worry. But it doesn’t mean the matric qualification has no value.

    3. A matric still provides an advantage

    In early 2024, nearly half of matriculants aged 15-24 were classified as not in employment, education or training. Almost 8 out of 10 of their peers who had dropped out of school were NEET. In short, you’re still more likely to get a job or further your studies with a matric certificate than without one.

    4. A hard road

    The road to opportunity beyond school is harder than it was a decade ago.

    Among NEET matriculants aged 15-24 at the start of 2014, 27% searched for work for more than a year. By early 2024, this figure had risen to 32%.

    It’s even worse for 25-34-year-old NEETs who hold a matric qualification. The percentage searching for work for over a year rose from 37% at the start of 2014 to 50% in early 2024.

    The longer young people remain disconnected from employment, education or training, the greater the toll on their mental health. NEET status is associated with worse mental health, particularly among young men.

    5. Post-school education and training

    The government has made ambitious plans to expand opportunities for young people to study further. But enrolments in post-school education and training are not growing sufficiently to match the rising tide in school completion or to absorb youth who cannot find jobs. And, with projected declines in real per student spending on post-school education as South Africa tries to address escalating national debt servicing costs, this situation is unlikely to improve anytime soon.

    The country is not keeping pace with tertiary enrolment rates in other developing nations like Brazil, Indonesia or China. For instance, 2021 estimates from the World Bank identify South Africa’s tertiary enrolment rate at 25%, compared to 41% in Indonesia, 57% in Brazil and 67% in China.

    6. Location matters

    Where someone lives in South Africa influences their chances for upward mobility. These inequalities are reflected in varying youth NEET rates across provinces. For instance, a third of recent matriculants in the Western Cape were not in employment, education or training in 2023/2024. That figure more than doubles in the North West province to 67%.

    How to help

    Two things are needed: improving labour market conditions and expanding post-school education and training opportunities.

    This is unlikely without improved economic growth.

    All of this may sound hopeless. But there are things that ordinary South Africans can do, too:

    • keep encouraging young people in your orbit to complete their schooling

    • where possible, spur them on to obtain a post-school qualification

    • use your social networks to connect youth to work experience opportunities, and help with CVs, referral letters and references.

    Young people must also adopt a practical, pragmatic and entrepreneurial mindset. They need to seize every opportunity available to them, whether in the labour market or post-school education.

  • MIL-OSI Submissions: How good are South African kids at maths? Trends from a global study

    Source: The Conversation – Africa – By Vijay Reddy, Distinguished Research Specialist, Human Sciences Research Council

    School mathematics in South Africa is often seen as a sign of the health of the education system more generally. Under the racial laws of apartheid, until 1994, African people were severely restricted from learning maths. Tracking the changes in maths performance is a measure of how far the country has travelled in overcoming past injustices. Maths is also an essential foundation for meeting the challenges of the future, like artificial intelligence, climate change, energy and sustainable development.

    Here, education researcher Vijay Reddy takes stock of South Africa’s mathematical capabilities. She reports on South African maths performance at grades 5 (primary school) and 9 (secondary school) in the Trends in International Mathematics and Science Study (TIMSS) and examines the gender gaps in mathematics achievement.

    What was unusual about the latest TIMSS study?

    The study is conducted every four years. South Africa has participated in it at the secondary phase since 1995 and at the primary phase since 2015. The period between the 2019 and 2023 cycles was characterised by the onset of the COVID-19 pandemic, social distancing and school closures.

    The Department of Basic Education estimated that an average of 152 school contact days were lost in 2020 and 2021. South Africa was among the countries with the highest school closures, along with Colombia, Costa Rica and Brazil. At the other end, European countries lost fewer than 50 days.

    Some academics measured the extent of learning losses for 2020 and 2021 school closures, but there were no models to estimate subsequent learning losses. We can get some clues of the effects on learning over four years, by comparing patterns within South Africa against the other countries.

    COVID learning losses: what South Africa’s education system must focus on to recover

    How did South African learners (and others) perform in the maths study?

    The South African grade 9 mathematics achievement improved by 8 points from 389 in TIMSS 2019 to 397 in 2023. From the trends to TIMSS 2019, we had predicted a mathematics score of 403 in 2023.

    For the 33 countries that participated in both the 2019 and 2023 secondary school TIMSS cycles, the average achievement decreased by 9 points from 491 in 2019 to 482 to 2023. Only three countries showed significant increases (United Arab Emirates, Romania and Sweden). There were no significant changes in 16 countries (including South Africa). There were significant decreases in 14 countries.

    Based on these numbers, it would seem, on the face of it at least, that South Africa weathered the COVID-19 losses better than half the other countries.

    However, the primary school result patterns were different. For South African children, there was a significant drop in mathematics achievement by 12 points, from 374 in 2019 to 362 in 2023. As expected, the highest decreases were in the poorer, no-fee schools.

    Of the 51 countries that participated in both TIMSS 2019 and 2023, the average mathematics achievement score over the two cycles was similar. There were no significant achievement changes in 22 countries, a significant increase in 15 countries, and a significant decrease in 14 countries (including South Africa).

    So, it seems that South African primary school learners suffered adverse learning effects over the two cycles.

    The increase in achievement in secondary school and decrease in primary school was unexpected. These reasons for the results may be that secondary school learners experienced more school support compared with primary schools, or were more mature and resilient, enabling them to recover from the learning losses experienced during COVID-19. Learners in primary schools, especially poorer schools, may have been more affected by the loss of school contact time and had less support to fully recover during this time.

    This pattern may also be due to poor reading and language skills as well as lack of familiarity with this type of test.

    Does gender make a difference?

    There is an extant literature indicating that globally boys are more likely to outperform girls in maths performance.

    But in South African primary schools, girls outscore boys in both mathematics and reading. Girls significantly outscored boys by an average of 29 points for mathematics (TIMSS) and by 49 points for reading in the 2021 Progress in International Reading Study, PIRLS.

    These patterns need further exploration. Of the 58 countries participating in TIMSS at primary schools, boys significantly outscored girls in 40 countries, and there were no achievement differences in 17 countries. South Africa was the only country where the girls significantly outscored boys. In Kenya, Zimbabwe, Zambia and Mozambique, the Southern and Eastern Africa Consortium for Monitoring Educational Quality (SEACMEQ) reading scores are similar for girls and boys, while the boys outscore girls in mathematics. In Botswana, girls outscore boys in reading and mathematics, but the gender difference is much smaller.

    In secondary schools, girls continue to outscore boys, but the gap drops to 8 points. Of the 42 TIMSS countries, boys significantly outscored girls in maths in 21 countries; there were no significant difference in 17 countries; and girls significantly outscored boys in only four countries (South Africa, Palestine, Oman, Bahrain).

    In summary, the South African primary school achievement trend relative to secondary school is unexpected and requires further investigation. It seems that as South African learners get older, they acquire better skills in how to learn, read and take tests to achieve better results. Results from lower grades should be used cautiously to predict subsequent educational outcomes.

    Unusually, in primary schools, there is a big gender difference for mathematics achievement favouring girls. The gender difference persists to grade 9, but the extent of the difference decreases. As learners, especially boys, progress through their education system they seem to make up their learning shortcomings and catch up.

    The national mathematics picture would look much better if boys and girls performed at the same level from primary school, suggesting the importance of interventions in primary schools, especially focusing on boys.

  • MIL-OSI Submissions: New survey explores what people in South Africa expect of publicly visible scientists – why it matters

    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.



    Read more:
    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.

    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 Analysis: Killer dolls and Brexit zombies – what to watch and do this week

    Source: The Conversation – UK – By Anna Walker, Senior Arts + Culture Editor

    Part of the appeal of the 2023 horror flick, M3gan, was that its titular antagonist managed to be two of the scariest villains of the genre in one – a killer robot, and a child’s doll come to life.

    After nine-year-old Cady (Violet McGraw) tragically lost her parents, her roboticist aunt Gemma (Allison Williams of Get Out fame) brought M3gan home to help her niece with the traumatic transition. M3gan was to be Cady’s teacher, playmate and above all, protector. In classic horror style, she soon embarked on a murderous rampage in the name of “protecting” her ward.

    The film was an instant cult hit, dubbed a “camp classic” thanks to M3gan’s TikTok dance moves and determination to destroy the nuclear family.

    In M3gan 2, in cinemas from today, the filmmakers have leaned into that campiness even more. But, as horror expert Adam Daniel explains that doesn’t completely neutralise the terror. Instead, it reformulates it, offering a cathartic release that makes the subject matter more digestible.

    I confess, I’m a bit of a baby when it comes to horror. So, I’ll need to follow up any zombie fare with something a little more comforting. My choice for this week is The Ballad of Wallis Island, which romcom giant Richard Curtis has dubbed “one of the great British films of all time”.

    It takes place on the fictional Wallis Island, home to millionaire Charles (Tim Key), an almost obsessive fan of former folk-rock duo played by Tom Basden and Carey Mulligan. Invited to the island to play a private gig, they must face their musical and romantic past, all under the gaze of an ecstatic Charles.

    The film was made in just 18 days on a tight budget in a typical Welsh summer – a doctor was on hand to stop the actors getting hypothermia when they filmed in the sea. It reminded our reviewer of another British comedy classic, Victoria Wood’s sitcom Dinnerladies, with its breadcrumb trail of slipped in details that provide laughter in the moment but which return to make the audience think twice.

  • MIL-OSI Analysis: The US’s asbestos U-turn: why the Environmental Protection Agency is reconsidering its ban

    Source: The Conversation – UK – By Allen Haddrell, Research Fellow, School of Chemistry, University of Bristol

    Once asbestos enters the lungs, it doesn’t leave. Its sharp, microscopic fibres scar tissues, trigger inflammation and can cause deadly diseases like mesothelioma, lung cancer and laryngeal cancer. That’s why over 60 countries have banned it – and why the US mostly phased it out.

    In 2024, the Environmental Protection Agency (EPA) moved to ban all industrial uses. But on June 17, the agency said it would revisit the Biden‑era ban.

    Asbestos is a naturally occurring silicate mineral made of thin, fibrous crystals. It is fire-resistant, durable, lightweight, flexible and insulating. This unique blend of properties resulted in its widespread use over millennia. Indeed, asbestos fibres have been found woven into pottery and textiles from 2500BC.

    Its resistance to friction and electricity made it desirable during the Industrial Revolution for use in boilers and steam engines. In the 20th century, the useful mix of physical properties resulted in asbestos becoming ubiquitous in the construction and automotive industries, peaking in the 1970s.

    Although the properties of asbestos at the macroscopic level are beneficial, at the microscopic level it’s anything but. When dust from asbestos (0.1 to tens of microns) is inhaled, it deposits throughout the respiratory system, causing inflammation and scarring of lung tissue.

    While the adverse health effects associated with asbestos exposure were observed in ancient Rome, it wasn’t until the 20th century that the full extent of harm was realised. Specifically, asbestos exposure is linked to numerous respiratory diseases, including mesothelioma, lung cancer and asbestosis.

    It took a long time for people to understand how dangerous asbestos really is. The main reason is that the illnesses it causes often don’t show up for decades. This long delay makes it very hard to link exposure to the disease it causes.

    Making this connection is also made more difficult when those most familiar with it, including manufacturers such as Johns-Manville and industry groups such as the Asbestos Information Association (AIA) were actively denying the connection, and suppressing reports demonstrating the link.

    By the 1970s, the volume of evidence showing the harms of asbestos had become overwhelming. The AIA evolved its argument, claiming that the practices in the industry had changed and that the risks were from a bygone era “when the dust control equipment in use was not as efficient or as sophisticated”. Although the association never explicitly admitted that asbestos caused harm.

    Since it can take decades for the health effects of asbestos exposure to fully manifest, the full extent of the damage caused by asbestos exposure from the 1970s and onward, an era where the dust control equipment was claimed to be “efficient and sophisticated”.

    The Asbestos Information Association, once a key industry group promoting the safe use of asbestos, quietly disbanded in the early 2000s as litigation and public health evidence mounted.

    History of asbestos.

    What type of asbestos is the US considering unbanning?

    The EPA is considering unbanning chrysotile asbestos, also called white asbestos. This type of asbestos is often used in things like brake pads, gaskets and industrial equipment. In March 2024 the EPA banned it, stopping new uses and imports. The ban also included a gradual phase-out plan.

    Who is pushing for the unbanning and why now?

    From the outset, industry groups such as the American Chemistry Council (ACC) raised concerns about the EPA’s ban, warning that “a prohibition of an estimated 52% of annual production volume … that rapidly, could have substantial supply chain impacts”, particularly if manufacturers were bound by existing contracts or chose to cease production entirely.

    As for why now, one factor is the re-election of Donald Trump, who put his views on record some time ago downplaying the dangers of asbestos. In 1997, he wrote in his book Trump: The Art of the Comeback that asbestos is “100 percent safe, once applied”. A point not supported by the best available science.

    Why is the EPA considering unbanning it?

    According to former ACC employee and current senior official in EPA’s Office of Chemical Safety and Pollution Prevention Lynn Ann Dekleva, they want to consider if the ban “went beyond what is necessary to eliminate the unreasonable risk and whether alternative measures — such as requiring permanent workplace protection measures – would eliminate the unreasonable risk”.

    What industries still want to use this type of asbestos?

    The largest push appears to be coming from the chlor-alkali industry where they use it to produce chlorine and sodium hydroxide.

    Is this type of asbestos dangerous?

    Yes. There is no safe level of exposure.

    How many people could this affect?

    Each year, around 40,000 deaths in the US and about 5,000 in the UK are attributed to asbestos exposure. If lifted, it’s possible that the number in the US could increase over the coming decades while those in the UK will continue to fall.

    Does this mean asbestos could make a comeback elsewhere too?

    Unlikely. While global consensus moves toward stricter regulation, the US now finds itself at a crossroads, between scientific evidence and pressure from industry.

  • MIL-OSI Analysis: Nato leaders pledge increased defence spending – is this really the price for peace and prosperity?

    Source: The Conversation – UK – By Damian Tobin, Lecturer in International Business, University College Cork

    Nato leaders agreed to ramp up defence spending to 5% of their countries’ economic output by 2035 at a summit in The Hague, Netherlands, on June 25. US president Donald Trump, who has spent months saying Europe should take more responsibility for its own security, described the pledge as “a monumental win for the US” and a “big win” for western civilisation.

    A few months earlier, in March, the EU also launched its long-awaited white paper on defence. This provides a blueprint for improving Europe’s readiness to respond to military threats by 2030. On top of the fact that global military spending has surged in the past ten years, these developments indicate that the world’s largest nations now prioritise military over economic diplomacy.

    One of the main ideas behind military diplomacy is that increased defence spending acts as a deterrent to future conflicts. The nuclear arms race between the US and Soviet Union during the cold war provides some support for this argument. The prospect of mutual destruction was so great that it acted as a deterrent to nuclear war.

    But is increased defence spending really the necessary price for greater peace and prosperity? My research on interactions between firms, geopolitics and the political economy of defence indicates that this is no “big win” for society or economic productivity.

    Deterrence requires a level of brinkmanship if it is to work. But as American economist Thomas Schelling pointed out in his 1960 book, The Strategy of Conflict, the problem with brinkmanship is that it relies on deliberately allowing a situation to get somewhat out of hand, with the intention of forcing the other party to back down.

    This can result in strategic blunders. Efforts by the former US president, Richard Nixon, to engineer such a situation in 1969 by threatening to use nuclear weapons in Vietnam failed to gain credibility with the Soviets and North Vietnamese. This undoubtedly helped convince North Vietnam that it could survive the war and locked the US into a much longer conflict.

    The recent confrontation between Israel and Iran also showed that brinkmanship can produce situations where there are significant casualties and no clear long-term resolution. Iran has long recognised that keeping itself near the threshold of nuclear weapons capability would offer a deterrent against external threats.

    But this strategy created many opportunities for error. Israel claimed that Iran was too close to building a nuclear weapon and, alongside the US, launched strikes that they say inflicted significant damage on Iranian nuclear enrichment capabilities and military leadership.

    Israeli aggression and Iranian nuclear brinkmanship made this confrontation all but inevitable

    Beyond this, it is unclear just how much military spending is needed to deter aggression. Nato allies have now committed to a big increase in defence spending – thanks largely to pressure from Trump.

    However, even Nato’s previous objective that countries commit 2% of their national income to defence has proved unattractive for many governments. This has even been the case in post-conflict areas such as the Balkans, where Nato has had a heavy involvement.

    A costly alternative

    Boosting defence spending falls short on delivering economic prosperity, too. Analysing US military spending in the Vietnam war, economist Les Fishman noted in 1967 that military diplomacy was far more costly than its economic equivalent.

    Military production requires continuously high levels of investment to maintain technological progress. This sucks public investment from other parts of the economy.

    That’s not to say defence spending has an entirely negative effect on the economy. Studies have found evidence that US federal funding of military research and development results in significant increases in private business research in sectors such as chemicals and aerospace.

    And, over the past decade, the value of venture capital deals in the US defence industry has grown 18-fold. This far outstrips sectors such as energy and healthcare. But such investment in military-related research and development is also often acknowledged as inefficient and not necessarily the best way to boost productivity.

    Fishman pointed out that the Marshall Plan, which provided substantial economic aid to western Europe after the second world war, had a far higher return for the US.

    Economic stabilisation kept the Soviet Union at bay for relatively small outlay compared to the Vietnam war, where casualties were of such a magnitude that it made any cost-benefit analysis meaningless.

    Boosting defence spending also represents a lost opportunity to invest in more socially beneficial projects. This will worsen the climate crisis.

    According to a study shared with the Guardian in May, the initial rearmament planned by Nato alone could have increased greenhouse gas emissions by almost 200 million tonnes a year. The expanded defence commitment will only increase this further.

    Unlike defence, where the repurposing of civilian technologies for military uses carries a cost to society, many green investments involve beneficial substitutions that reduce the cost of a green transition.

    The substitution of conventional fossil fuel heating and transport systems with heat pumps and electric vehicles, for example, is far more socially beneficial than repurposing civilian satellites for missile systems.

    A final point is that military diplomacy is itself geopolitically destabilising. US efforts to contain communism in Asia during the 1950s and 1960s are a good example. Not only did such efforts see China align its trade with other communist states, it also ensured that self-reliance became a cornerstone of China’s economic strategy.

    This all suggests that the current drive for deterrence-based military spending carries with it a huge cost for society that could ultimately prove economically wasteful and geopolitically destabilising.

    Nato leaders agreed to ramp up defence spending to 5% of their countries’ economic output by 2035 at a summit in The Hague, Netherlands, on June 25. US president Donald Trump, who has spent months saying Europe should take more responsibility for its own security, described the pledge as “a monumental win for the US” and a “big win” for western civilisation.

    A few months earlier, in March, the EU also launched its long-awaited white paper on defence. This provides a blueprint for improving Europe’s readiness to respond to military threats by 2030. On top of the fact that global military spending has surged in the past ten years, these developments indicate that the world’s largest nations now prioritise military over economic diplomacy.

    One of the main ideas behind military diplomacy is that increased defence spending acts as a deterrent to future conflicts. The nuclear arms race between the US and Soviet Union during the cold war provides some support for this argument. The prospect of mutual destruction was so great that it acted as a deterrent to nuclear war.

    But is increased defence spending really the necessary price for greater peace and prosperity? My research on interactions between firms, geopolitics and the political economy of defence indicates that this is no “big win” for society or economic productivity.

    Deterrence requires a level of brinkmanship if it is to work. But as American economist Thomas Schelling pointed out in his 1960 book, The Strategy of Conflict, the problem with brinkmanship is that it relies on deliberately allowing a situation to get somewhat out of hand, with the intention of forcing the other party to back down.

    This can result in strategic blunders. Efforts by the former US president, Richard Nixon, to engineer such a situation in 1969 by threatening to use nuclear weapons in Vietnam failed to gain credibility with the Soviets and North Vietnamese. This undoubtedly helped convince North Vietnam that it could survive the war and locked the US into a much longer conflict.

    The recent confrontation between Israel and Iran also showed that brinkmanship can produce situations where there are significant casualties and no clear long-term resolution. Iran has long recognised that keeping itself near the threshold of nuclear weapons capability would offer a deterrent against external threats.

    But this strategy created many opportunities for error. Israel claimed that Iran was too close to building a nuclear weapon and, alongside the US, launched strikes that they say inflicted significant damage on Iranian nuclear enrichment capabilities and military leadership.

  • 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.

    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.”

    Study participants worried that the Colorado fentanyl criminalization bill will deter people from reporting an overdose for fear of being arrested.

    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.
    Hyoung Chang/GettyImages

    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.

    Many nostalgia-inducing scents vary from person to person, but pumpkin pie spice may be one of the most evocative scents in the U.S.

    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

    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.
