    US President Donald Trump’s 90-day pause on implementing so-called “reciprocal” tariffs on some 180 trading partners ends on July 8.

    How are countries responding to the threat, and will the tariffs be re-applied from July 9?

    What the US thinks ‘reciprocal’ means

    The United States is demanding four things from all trading partners, while offering little in return. So these negotiations are anything but “reciprocal”.

    The main demand is to rebalance bilateral goods trade between the US and other countries. Nations with trade surpluses – meaning they export a greater value of goods than they import from the US – will be encouraged to import more from the US and/or export less to it.

    The US is also pushing countries to eliminate a range of “non-tariff barriers” that may affect US export competitiveness. These barriers are drawn from the United States Trade Representative’s (USTR) March 2025 report and include a variety of perceived “unfair” practices, from value-added taxes (such as the Goods and Services Tax) to biosecurity standards such as those Australia applies to agricultural imports.

    In a nod to the “tech bros”, (alleged) restrictions on digital trade services, such as Australia’s media bargaining code, and digital service taxes must be removed, along with taxes on the tech giants. On Monday, Canada dropped a new digital service tax on firms such as Google and Meta after Trump suspended trade talks.

    Countries must also agree to reduce reliance on inputs from China in any exports to the United States. That means companies that moved manufacturing from China to countries such as Vietnam during President Trump’s first term trade wars will face challenges in sourcing input components from China.

    Put together, this is a difficult package for any government to accept without securing something in return.

    Who holds the cards?

    Trump has been fond of saying the United States holds “all the cards” in trade negotiations.

    It’s not known precisely how many countries are negotiating bilateral deals with Washington. Between 10 and 18 countries are priority “targets”, or to use an early, colourful phrase, were targeted as the “Dirty 15”.

    Category 1 likely comprises many more countries than those in the US’s naughty corner. These countries were saddled with large reciprocal tariffs despite the tariff formula’s evident shortcomings. To paraphrase Trump, these countries don’t hold the cards and have limited negotiating power.

    They have no choice but to make concessions. The smarter ones will take the opportunity to make reforms and blame the bully in Washington. Mostly these are developing countries, some with high dependency on the US market, including the poorest such as Bangladesh, Cambodia, and Lesotho.

    To make matters worse, they must keep one eye on China for fear of retribution in case Beijing perceives any promises to reduce dependence on Chinese inputs would compromise Chinese interests.

    Category 2 consists of countries that “hold cards”, or have some degree of leverage. Some, such as Canada, Japan, India and the EU, will secure limited US concessions although they may resort to retaliation to force this outcome. From discussions with our government and academic sources, Japan and India likely won’t retaliate, but Canada has previously and the EU likely will.

    Australia’s Prime Minister Anthony Albanese initially said he would not negotiate and has repeated US reciprocal tariffs “are not the act of a friend”.

    However, the Australian government is wisely looking to bolster its negotiation cards, such as creating a critical minerals strategic reserve.

    No doubt policy makers are also reminding the US of their favourable access to Australia’s military infrastructure which could be essential to any US-China military confrontation.

    China is category 3.

    The Chinese government is determined not to kowtow to Washington as they did in Trump’s first term. The so-called “Phase 1 deal” was signed but instantly forgotten in Beijing.

    Beijing has several cards, notably dominance of processed critical minerals and their derivative products, particularly magnets, and the US’s lack of short-term alternative supply options.

    After China expanded export controls on rare earths and critical minerals, shortages hit the auto industry around the world and Ford was forced to idle plants.

    What happens next?

    Kevin Hassett, director of the National Economic Council, suggested on Friday more deals may be signed before July 8. But Trump is likely to undermine and/or negate them as his transactional whims change.

    The British, after announcing their US deal that included relatively favourable automotive and steel export market access, watched in horror as Trump doubled tariffs on steel imports to 50%, and reimposed the 25% tariff on the UK.

    The UK government was reminded this US administration cannot be trusted. That is why countries negotiate binding trade treaties governed by domestic and international laws.

    Many countries are waiting on the outcomes from various US court battles testing whether the president or Congress should have the power to impose unilateral tariffs. After all, if there is a chance the Supreme Court rules Trump cannot change tariffs by decree, then why negotiate with a serially untrustworthy partner?

    The Japanese government, for example, recently announced it is pausing negotiations after the US demanded increased defence spending.

    ‘I’m going to send letters’

    Trump on Sunday suggested he would simply send letters to foreign nations setting a tariff rate. “I’m going to send letters, that’s the end of the trade deal,” he said.

    That does not bode well for countries negotiating in good faith. It’s likely tariffs will be reimposed and bilateral negotiations will drag on to September or beyond as Treasury Secretary Scott Bessent has said.

    After all, even the US government has limited bandwidth to process so many simultaneous negotiations. Category 2 trading partners will increasingly test their own political limits. And the rest of the world is hoping for a favourable Supreme Court ruling that may, like the character Godot in the play Waiting for Godot, never come.

  • MIL-Evening Report: A new ‘prac payment’ has just kicked in. But it ignores many uni students

    Source: The Conversation (Au and NZ) – By Kelly Lambert, Associate Professor Nutrition and Dietetics, University of Wollongong

    On Tuesday, some Australian university students got access to a new payment. The Commonwealth Prac Payment is available to eligible teaching, nursing, midwifery and social work students.

    It will provide A$331.65 a week during compulsory professional placements, to help with living and study expenses. This could include travel, accommodation, uniforms and lost income from other employment.

    But while the payment is a much-needed step in the right direction, many students are still missing out.

    Who’s not covered?

    The prac payment was a recommendation from the federal government’s 2024 Universities Accord review. It is designed to help students complete essential professional placements, so they can graduate and enter the workforce.

    But numerous other health degrees with time-consuming work placements are excluded from the payment.

    This includes medicine, physiotherapy, dietetics, psychology, radiography and other allied health professions. Veterinary medicine students are also ineligible. Many of these professions are also experiencing serious workforce shortages.

    The payment is also only available to teaching, nursing and social work students who already qualify for Ausstudy (the income support payment for students and apprentices who are 25 and over).

    So this means the prac payment is means tested. It is also considered taxable income and paid at the rate of Austudy – which is not generous. The basic Austudy rate is below the national poverty line.

    The payment is also only available to Australian domestic students, even though many international heath students end up working in the Australian health system after graduating.

    Why is this an issue?

    Researchers, including ourselves, use the term “placement poverty” to describe the impact mandatory placements can have on students. It can be a major barrier to students completing their degrees.

    Students have repeatedly described widespread impacts of doing up to 1,000 hours of unpaid work to graduate – taking a toll on their income and mental health.

    Kelly Lambert’s 2024 research suggests health and teaching students can incur a further $12,500–15,000 to the cost of degrees during unpaid placements.

    Students have explained the placement hours mean they can’t work in their regular paid casual or part-time jobs – and may lose this work as a result.

    What does this mean for students?

    In the short term, if students are not supported to complete their placements, they may not have enough money for food or accommodation.

    Our research found 29% of teaching and allied health students regularly skip meals while on placement. Some students also described sleeping in cars or driving excessive distances due to limited or expensive accommodation options near their placements.

    If students are not supported in their placements, research suggests they can experience burnout and may not finish their degrees. Or they may not even begin them in the first place.

    This is particularly the case for students from regional or rural communities (who may have further to travel), students with parenting or caring responsibilities, and students from low economic and otherwise disadvantaged backgrounds.

    We also know its important to support students to do placements in rural, regional and remote areas – students who complete placements in these communities are more likely to return and work in those communities.

    What do we need to do instead?

    As a first measure, the government should expand eligibility criteria for the current payment to include other health disciplines and those who don’t currently meet the means testing threshold.

    Research tells us financial hardship is not confined to students who qualify for Austudy, it is experienced across the board.

    Students have also suggested interest-free short-term loans, subsidised parking (similar to hospital employees), and greater transparency about the costs associated with unpaid placements. International students have also said public transport subsidies would help them complete their placements.

    Other, more significant changes could include apprenticeship-type compensation models for healthcare students, where students get paid to study as part of their training. These schemes are already available in Scotland.

    Ultimately, we want to support more students to do health and teaching degrees to fill workforce gaps – not discourage them with high costs of studying.

  • MIL-Evening Report: 2 polls have Tasmania headed for another hung parliament, but disagree on which party is ahead

    Source: The Conversation (Au and NZ) – By Adrian Beaumont, Election Analyst (Psephologist) at The Conversation; and Honorary Associate, School of Mathematics and Statistics, The University of Melbourne

    Two Tasmanian state polls imply another hung parliament at the July 19 election under Tasmania’s proportional system. In one of these polls, Labor leads the Liberals, while in the other the Liberals lead.

    A Tasmanian snap state election will be held on July 19, just 16 months after the previous election in March 2024. This election is being held owing to a successful early June no-confidence vote in Liberal Premier Jeremy Rockliff.

    Tasmania uses the proportional Hare-Clark system to elect its lower house. There are five electorates corresponding to Tasmania’s five federal seats, and each electorate returns seven members, for a total of 35 lower house MPs.

    Under this system, a quota for election is one-eighth of the vote or 12.5%, but half of this (6.2%) is usually enough to give a reasonable chance of election. There’s no above the line section like for the federal Senate. Instead, people vote for candidates not parties, with at least seven preferences required for a formal vote.

    Robson rotation means that candidates for each party are randomised across ballot papers for that electorate, so that on some ballot papers a candidate will appear at the top of their party’s ticket and on others at the bottom.

    This means parties can’t control the ordering of their candidates. Independents can be listed in single-candidate columns.

    At the last election, the Liberals won 14 of the 35 seats, Labor ten, the Greens five, the Jacqui Lambie Network (JLN) three and independents three. Two of the three JLN MPs were later expelled from their party, but remained in parliament as independents.

    Candidate nominations were declared last Friday. There are 31 candidates in Bass, 38 in Braddon, 26 in Clark, 31 in Franklin and 35 in Lyons, for a total of 161 candidates, or 4.6 candidates per vacancy.

    The JLN isn’t running candidates, but the Nationals are running in Bass, Braddon and Lyons, and they include two former JLN MPs. Previous Tasmanian attempts by the Nationals have been failures, with their last effort in 2014 earning them just 0.8% of the statewide vote.

    YouGov and DemosAU polls

    A Tasmanian YouGov poll, conducted June 12–24 from a sample of 1,287, gave Labor 34% of the vote, the Liberals 31%, the Greens 13%, independents 18% and others 4%. Despite trailing on voting intentions, Rockliff led Labor’s Dean Winter by 43–36 as preferred premier.

    Respondents were asked to select the three most important items they wanted their candidate to agree with. Investing more in health was selected by 52%, building more public housing by 45% and reducing state debt by taxing those who can afford to pay by 41%.

    Opposing privatisation and asset sales was selected by 34%, while supporting privatisation was selected by 18%. Being anti-Macquarie AFL stadium was selected by 33%, while being pro-stadium was selected by 22%. When asked specifically about privatisation, voters were opposed by 47–36.

    Analyst Kevin Bonham reported a DemosAU poll, conducted June 19–26 from a sample of 4,289, gave the Liberals 34% of the vote, Labor 27.3%, the Greens 15.1% and independents 19.3%, leaving 4.7% presumably for others. This poll was originally reported in The Advocate, and was taken for an “unnamed peak body”.

    Bonham thinks it is likely that the independent vote in both these polls is overstated. These polls were both conducted before nominations were declared.

    If the DemosAU poll is correct, the Liberals would be likely to win more seats than Labor, while Labor would be likely to win more seats if the YouGov poll is right. But in both cases, the winning party would be well short of the 18 seats needed for a single-party majority.

    From 2010 to 2014, Labor governed in coalition with the Greens, and its heavy loss at the 2014 election was widely blamed on this coalition. Labor has tried to distance itself from the Greens since. In the last parliament, Labor may have been able to form government with the Greens’ assistance, but they refused to attempt to form one.

    If the YouGov poll is right, Labor may be able to form government with independents and not require the Greens. If the DemosAU poll is right, the result of this election is likely to be similar to the 2024 result, and Labor would need the Greens and some independents to form government.

    Federal Morgan poll: Labor far ahead

    A national Morgan poll, conducted June 23–29 from a sample of 1,522, gave federal Labor a 57.5–42.5 lead by headline respondent preferences, a 0.5-point gain for the Coalition since the June 2–22 Morgan poll.

    Primary votes were 36.5% Labor (down one), 30.5% Coalition (down 0.5), 12% Greens (steady), 8.5% One Nation (up 2.5) and 12.5% for all Others (down one). Using 2025 election preference flows, Labor’s lead was reduced to 56.5–43.5.

  • MIL-Evening Report: Trauma is carried in your DNA. But science reveals a more complicated story

    Source: The Conversation (Au and NZ) – By Tara-Lyn Camilleri, Postdoctoral researcher of transgenerational effects, Monash University

    Radu Bercan/Shutterstock

    As war continues to rage in Gaza and Ukraine, there is concern about how the related trauma might be transmitted to future generations of people in those regions.

    More generally, interest in the idea of transgenerational trauma has recently surged. For example, earlier this year, National Geographic magazine asked whether genes carry past family trauma.

    But while this might be a catchy question, it’s also slightly misleading. Because while trauma can ripple across generations, shaped by how our bodies respond to their environments, its effects aren’t hard-coded in our genes.

    Plastic minds and bodies

    At the heart of this process is what’s known as phenotypic plasticity.

    This is the capacity for organisms to produce different outcomes from the same genes, depending on their environment. These outcomes, called phenotypes, can include stress sensitivity and body shape.

    One way different phenotypes can arise from the same genes is via epigenetics: small chemical changes to the DNA molecule that make particular genes more or less active. Think of these like a director’s notes on a script. These notes guide the cell on which lines to emphasise or soften, without changing the script itself.

    But epigenetics is just one way this plasticity is expressed.

    Understanding how trauma is passed across generations means looking beyond genes and cells to the environments that shape and influence them.

    Human development is sculpted by lived experience, from caregiving and community to stress, safety and belonging.

    These factors interact to produce lasting – but not always fixed – effects. By focusing on how they interact, rather than on single causes, we can better understand why trauma echoes across generations. This also helps us identify how that cycle might be disrupted.

    Widespread in nature

    Phenotypic plasticity is widespread in nature.

    In honeybees, genetically identical larvae become queens or workers depending on what they eat while developing. In three-spined stickleback fish, early exposure to predators reshapes their stress physiology and body shape, making them harder for predators to grasp.

    These aren’t genetic differences – they’re environmental effects on development.

    In humans, early-life conditions similarly shape development. A child raised in an unsafe setting may develop heightened vigilance or stress sensitivity – traits that help in danger but can persist as anxiety or chronic stress in times of safety. This is known as environmental mismatch.

    Across generations, plasticity becomes more complicated. In some of my past research, I studied how diet in one generation of fruit flies shaped health, reproduction and longevity in their offspring and grand offspring.

    The results varied depending on diet, generation and trait. Traits that appeared to be useful in one generation weren’t always so in the next. This highlights how difficult transgenerational effects are to predict – precisely because of this plasticity.

    In three-spined stickleback fish, early exposure to predators reshapes their stress physiology and body shape.

    Too narrow an explanation

    Epigenetics often reflect environmental exposures – such as stress, trauma, nutrition or caregiving. But they’re not necessarily permanent “scars”. Many are dynamic and can shift with changing environments – especially early in life.

    Studies show that epigenetic patterns linked to early childhood adversity vary depending on later environments such as family stability and social support. This suggests the biological imprint of early stress is shaped by what happens next.

    It’s tempting to treat epigenetics as the key to explaining inherited trauma – but that’s too narrow. Trauma can influence the next generation through altered hormones, immune function or in utero conditions – all of which shape brain development and stress reactivity.

    Genetic variation also plays a major role. It doesn’t encode trauma itself, but it shapes traits such as sensitivity to threat or emotional regulation. These traits aren’t chosen – they arise from a web of biological and social influences beyond our control.

    But how they unfold, and whether they’re amplified or softened, depends on the systems that surround us.

    Connection to culture

    Connection to culture plays an important role too.

    In Aotearoa New Zealand, Māori-led initiatives that centre land, language and whakapapa (ancestral lineage) have shown promise in restoring wellbeing after generations of colonisation-related trauma.

    For Holocaust survivors and descendants, connection to cultural identity through ritual and shared narrative can reduce the psychological burden of transmitted trauma.

    But not all trauma is collective or institutional. Interventions such as trauma-informed parenting and early relational therapies have been shown to improve outcomes in the next generation.

    These psychological supports affect biology. Feeling safe in our relationships, having stable routines and a sense of meaning can reduce stress hormones, modulate immune function, and buffer against long-term disease risk.

    In this way, culture, caregiving and connection are all biological interventions. When they soften the effects of earlier stress, they may help interrupt its transmission.

    Trauma-informed parenting has been shown to improve outcomes in the next generation.

    Reframing inherited vulnerability

    This matters, because it changes how we understand inherited vulnerability.

    Rather than a permanent wound passed down through DNA, the effects of trauma are better understood as changeable responses shaped by context.

    Thanks to plasticity, our biology is always in conversation with the environment – and when we change the context, we can change the outcome.

  • MIL-Evening Report: Aamir Khan’s big screen comeback, Sitaare Zameen Par, features an all-star neurodivergent cast – a Bollywood first

    Source: The Conversation (Au and NZ) – By Yanyan Hong, PhD Candidate in Communication, Media and Film Studies, University of Adelaide

    Bharti Dubey/X

    Bollywood star Aamir Khan’s return to the big screen after a three-year hiatus has been far from ordinary. Sitaare Zameen Par (2025) which translates to “stars on Earth”, is the first major Bollywood production to feature a mostly neurodivergent cast.

    A remake of the 2018 Spanish film Campeones, the story follows a mouthy, knuckle-headed basketball coach, Gulshan (Aamir Khan), who is put in charge of a team of players with intellectual disabilities.

    The film slowly grows into itself, much like its characters, but ultimately delivers what the trailer promises: a heartwarming, humorous and uplifting celebration of our individual differences.

    In an era of blockbuster spectacles, Aamir Khan Productions brings back a kind of Bollywood storytelling we haven’t seen in a while – something sincere, gentle and quietly revolutionary.

    Who is Aamir Khan?

    Aamir Khan was born in Mumbai in 1965, and started his acting career as a child actor in his uncle’s film Yaadon Ki Baaraat (1973).

    Khan is now one of Bollywood’s most enduring and respected figures. He is one of the iconic “three Khans”, alongside Shah Rukh Khan and Salman Khan (the three are unrelated), who have dominated Indian cinema since the 1990s.

    But unlike his Khan counterparts, Aamir Khan has carved a unique career path built on both commercial success and socially-driven storytelling.

    He is known for championing social causes through cinema. In one 2015 article, media studies professor Vamsee Juluri referred to him as a “national conscience figure”.

    Khan’s films don’t just entertain; they challenge norms and often spark national conversations on important issues.

    From producing Lagaan: Once Upon a Time in India (2001), India’s Oscar-nominated colonial-era sports epic, to his directorial debut Taare Zameen Par (2007), a moving portrait of a child with dyslexia, Khan’s work often brings underrepresented stories to the mainstream.

    Lagaan follows farmers from a small Indian village under British colonial rule. The British challenge the farmers to a game of cricket, in exchange for an exemption from paying the land tax (‘lagaan’).
    IMDb

    His film PK (2014) challenges religious dogma. Meanwhile, Dangal (2016) is a boundary-pushing film based on real-life female wrestlers from rural India, and is also Bollywood’s highest-grossing film of all time.

    Beyond the box office, Khan has hosted the TV show Satyamev Jayate (2012–14), which is also the national emblem of India, meaning “truth alone triumphs”.

    This show tackles various topics considered taboo in Indian societies, including female feticide, domestic violence and caste discrimination. It has reached millions of households, and even ignited parliamentary debates.

    Khan is also popular in other countries, including China, where his films 3 Idiots (2009), Dangal (2016) and Secret Superstar (2017) were massive hits that resonated with audiences for their universal themes.

    In Dangal (2016), Mahavir (Aamir Khan) trains his two daughters in wrestling.
    IMDb

    Sitaare Zameen Par marks his return following the commercial underperformance of Laal Singh Chaddha (2022), an Indian remake of Forrest Gump (1994).

    Sitaare (stars) who make the film shine

    Directed by R.S. Prasanna, Sitaare Zameen Par enjoyed a strong opening weekend at the box office.

    It stars ten individuals with special needs as they prepare for a basketball tournament under the direction of their coach (Khan). This plot alone makes the film a significant entry to Indian cinema, which often ignores or misrepresents disability.

    The neurodivergent stars of Sitaare Zameen Par are aged between 18 and 42.
    Aamir Khan Productions.

    Despite early online trolling and negativity, the film depicts its neurodivergent characters not as victims, or “inspirations”, but simply as people with dreams, struggles and joy.

    One line captures this beautifully: “Everyone sticks to their own normal. We each have our own normal.”

    Aamir Khan, now 60, plays a key role in the film, but doesn’t dominate it. Instead, his younger co-stars shine. The result is a healing film that celebrates inclusion, while being full of joy and humanity.

    Stories that matter

    No film is perfect. But it’s hard to dislike a film made with so much compassion.

    Bollywood as an industry has increasingly leaned into action-packed blockbusters, as well as nationalist and Hindu-centred narratives (such as in the 2022 film Brahmāstra).

    While many of these offer thrills, few deliver the kind of emotional and social depth that once defined Hindi cinema’s global appeal. Much like Taare Zameen Par – a spiritual prequel to the new release – did 18 years ago, Sitaare Zameen Par invites the audience to slow down and reflect.

    In Taare Zameen Par (2007), Khan plays a neurotypical teacher who helps a student with dyslexia.
    IMDb

    It prompts neurotypical viewers to see people with Down’s syndrome as part of the same emotional universe as them – and to laugh with, not at them.

    In an interview, Khan explains how the film goes further than just neurodivergent representation, to participation:

    In [Taare Zameen Par], it’s the teacher, Nikumbh, a supposedly neuro-typical person, who helps the child with dyslexia. In this film, ten neuro-atypical people are helping the coach, Gulshan. I feel Sitare takes the discourse of the first film ten steps ahead, especially in our country where people need to be sensitised to the topic of neurodivergence.

    Last week, India’s president, Droupadi Murmu, attended a special screening and met the cast. The visit sent a clear messsage: stories like this matter.

    With Sitaare Zameen Par, Aamir Khan returns to what he does best: using film as both a mirror and message for Indian society. While it won’t change the world overnight, it will make viewers see the world, and each other, a little differently.

  • MIL-OSI Submissions: Funding terror: how west Africa’s deadly jihadists get the money they need to survive

    Source: The Conversation – Africa (2) – By Egodi Uchendu, Professor (of History and International Studies), University of Nigeria

    The west Africa–Sahel region has seen a proliferation of militant Islamist groups since the 1990s.

    One of the most vicious groups operating in the region is Jama’at Nusrat al-Islam wal-Muslimin (Support Group for Islam and Muslims). The militant group emerged in 2017 in Algeria and Mali, and has targeted civilian populations.

    The UN listed the group as an al-Qaeda affiliate in 2018. Al-Qaeda is an Islamist organisation founded by Osama bin Laden in the 1980s.

    The 2024 global terrorism index listed Jama’at Nusrat al-Islam wal-Muslimin as one of the world’s most dangerous terrorist organisations. Its influence has expanded in most parts of the Sahel. The group emerged to strengthen the jihadist insurgency under al-Qaeda. It combines violence with diplomacy to expand its influence and challenge state authorities.

    Despite growing pressure from counter militancy campaigns spearheaded by local, regional and international militaries, Jama’at Nusrat al-Islam wal-Muslimin continues to survive and adapt by regrouping and reorganising. This was demonstrated in its latest operation in Burkina Faso in 2024. The group exerted significant control by closing schools, setting up taxation checkpoints and abducting locals.

    Its engagement in illicit economies has been key to the group’s successful expansion. This revenue is used to carry out devastating attacks.

    We research jihadi-based insurgencies, and have found that this is a common tactic among terrorist groups in the west Africa-Sahel axis, including Boko Haram militants.

    From our research, we find that Jama’at Nusrat al-Islam wal-Muslimin funds its activities by relying on

    • artisanal mining

    • kidnapping

    • livestock theft

    • money laundering.

    Dismantling the group’s illicit economies and blocking its financial flows are key to countering its activities.

    Financial resources

    The group needs money for fighting, and to sustain political and social influence in its areas of operation.

    Artisanal gold mining has proven to be a major factor in its expansion and resilience. In areas where the group exerts influence, illicit gold mining generates over US$30 billion annually. According to a report by Swissaid, a development group based in Switzerland, the main destinations for this gold are the United Arab Emirates, Turkey and Switzerland.

    The jihadists gain access to gold by controlling mining sites and transport routes to and from mines. They sometimes allow trusted allies, who include local armed groups, bandits and other criminal networks, to mine in exchange for a payout. The extent of gold mining funds is not exactly known, but the artisanal sites in areas controlled by the group have the capacity to produce 725 kilograms of gold per year, valued at US$34 million.

    West Africa could soon have a jihadist state – here’s why


    Another source of income – and political influence – is kidnapping for ransom. Kidnap victims include cattle owners, businessmen, state officials and foreigners. The group received a ₤30 million ransom in 2020 to release one French and two Italian hostages. Between 2017 and 2023, the group and its affiliated units were responsible for 845 out of approximately 1,100 recorded kidnappings in Mali, Burkina Faso and Niger. Burkina Faso and Mali remain the epicentre of the group’s violent activities. In the first quarter of 2023, over 180 cases of kidnapping were recorded in these countries’ war-torn areas.

    Livestock theft has also been a critical source of funds. The practice of livestock theft as economic warfare and a means to generate funds has led to livestock being forcibly taken from herders who fail to pay zakat (a religious fee among Muslims) or subscribe to the group’s ideology. The stolen livestock are sold in Mali, Mauritania or Senegal. The ability to monetise stolen livestock makes their theft a cornerstone of the Sahelian war economy and a source of cash for weapons and vehicles.

    Money laundering is another illicit economy central to the militant group’s financing. It lends money to merchants, invests with banks and funds small shops with the aim of getting profits. This helps ensure a constant flow of money and provisions to support the group’s terrorist acts. It has attached much importance to this illicit economy, to the extent of assassinating those who interfere with its investments.

    Way out

    To cut down Jama’at Nusrat al-Islam wal-Muslimin’s financial base – and thereby weaken its capacity for militancy – counterinsurgency efforts need to take the following actions.

    • Government security actors should collaborate with local self-defence militias to regulate artisanal mining and thwart kidnappings.

    • Financial intelligence units need to identify merchants who receive money from the militant group to block the flow of illicit funds.

    • Specialised courts that deal with money laundering and terrorism financing cases should be established and made operational in Burkina Faso and Mali, the epicentres of the group’s activities.

    • Burkina Faso and Mali should increase security around civilians to minimise civilian casualties from terror operations.

    Since finance is the basis of the militant group’s strength, regional security co-operation should be strengthened. This would help with systematically tracking illicit flows and stopping them.

  • MIL-OSI Submissions: Universities must teach students what freedom is – a South African course is trying to do just that

    Source: The Conversation – Africa – By Pedro Tabensky, Director, Allan Gray Centre for Leadership Ethics, Rhodes University

    A typical student wants a university degree as a ticket to a salary. For this young person, education is a journey towards “having”. And the way to complete the journey is mainly to remember, repeat or reproduce what the teacher says and does.

    This having-orientation is understandable given the often precarious realities of life, particularly in the global south, including South Africa, where I am based as a university lecturer. It is understandable, yet it fosters apathy in the classroom, for the monetary aims of students are not typically aligned with the aims of learning.

    In response to this situation, for a decade Rhodes University’s Allan Gray Centre for Leadership Ethics has been developing a course called IiNtetho zoBomi, which translates from isiXhosa, one of South Africa’s languages, as “conversations about life”.

    IiNtetho zoBomi is a year-long course offered to all students at the university. Over 2,000 have completed it since its inception. It aims to bridge the gap between character education and vocational education. The course shows students how interrelated reading, writing, thinking and being are.

    It’s an opportunity for students to think about what matters to them and how to live accordingly. We hope they learn to have a say in how their lives will go. We want them to understand how education will equip them for life – not just work – and promote self-mastery. Ideally, students will realise along the way that self-mastery comes from learning with others in communities of inquiry.

    With my colleagues at the centre, I wrote about the course in a recent paper, explaining the thinking behind it and how it works. From initial reticence and outright suspicion, the course is starting to receive broad institutional support from academics and management. The idea has been mooted that it should become become a common course for all first-year students.

    The course has also received an endorsement from educational sociologist Kathy Luckett and feminist philosopher Ann Cahill. In their review of the course they commented that it had developed “a unique and powerful form of pedagogy that is clearly speaking to students’ interests and existential needs, and effectively providing students with capacities that allow them to author their own thoughts and lives”.

    Inquisitiveness versus apathy

    If a salary is the overriding motive for pursuing higher education, it helps to explain why so many students seem to lack inquisitiveness to seek knowledge, and hence are not in the correct frame of mind required for deep learning and the human growth that comes with the learning mindset.

    This lack of inquisitiveness is also encouraged by the fact that the global university has primarily become a market service provider. The market wants and needs professionals, and universities provide them. This may not be a problem, unless the professional aspect of human life is separated, as it often is, from the central goal of education: to form well-adjusted, autonomous human beings.

    It’s important to rethink the purpose of university education — a philosopher of education explains why


    This severance between learning for work and learning for life leaves human growth to chance. It fosters the passive absorption of whatever happens to be in the air of the times, instead of the formation of a capacity for critical thinking necessary for autonomy.

    Contemporary universities presume that if one looks after people’s career concerns, life will look after itself, which is a grave mistake.

    Conversations about life

    The course includes student-led lectures, peer dialogues and weekly service learning at local no-fee paying public primary schools. The students also keep journals in which they reflect on their lives in relation to the course’s material.

    We introduce students to ideas such as the existential psychologist Erich Fromm’s distinction between “being” and “having” orientations to education. In other words, a good education helps you to be a certain way, not just to have certain things.

    Students also learn that “to take freedom for granted is to extinguish the possibility of attaining it”, as expressed in the documentary Creating Freedom: The Lottery of Birth. This is the idea that people are shaped by circumstances, and understanding how these circumstances shape them is a first step in attaining real freedom. We show this documentary to our students in addition to other movies and documentaries about the weekly topics discussed in class.

    We encourage students to develop an inner dialogue and understand that they passively absorb much of what their thinking draws on. We challenge students to consider what they see, or fail to see, and how they see it. We invite students to reflect on how external forces like peer pressure and ideology act on them, as do internal forces like the confirmation bias (which motivates us to favour information that confirms what we already believe and to ignore information that doesn’t).

    The following idea frames the content of the course: barriers to acting ethically, indeed to autonomy, are produced by psychological, social and political forces.

    Then there is the service-learning aspect of Iintetho zoBomi.

    This is about the students getting involved in communities and learning through one-on-one interactions with children at no-fee primary schools, helping them with English literacy and life orientation-related schoolwork. Our students learn by teaching learners material that’s related to IiNtetho zoBomi. Service learning helps bring ideas and experiences together.

    Responses

    We are seeing encouraging results in the form of hundreds of unsolicited comments relating to how the course has transformed the lives of our students.

    Most of these comments come from student reflective journals. Lecturers read the journals as the main form of assessment of IiNtetho zoBomi. Some students even wrote articles in local media about what they had learned. In one of the articles, student Tanatswa Chivhere concludes that:

    Most of us who have done the course can testify to how it made us more aware of how our thoughts and actions impact the world as a whole. IiNtetho zoBomi has changed the way in which I view my place in the world and how to use that place to better not only my life, but those of others around me.

  • MIL-OSI Submissions: Moroccan schools are fuller thanks to cash grants. The problem now is the quality of their education – study

    Source: The Conversation – Africa – By Jules Gazeaud, Chargé de recherche CNRS, Université Clermont Auvergne (UCA)

    Reprinted by permission from VoxDev

    The spread of conditional cash transfer programmes in low- and middle-income countries has been described as perhaps the most remarkable innovation of recent decades in welfare programmes. These programmes provide regular cash transfers to poor families contingent on specific behaviours. These include school enrolment and regular attendance.

    The programmes started in the late 1990s in Mexico and quickly became the public policy of choice to fight poverty and low enrolment. Today, more than 60 countries operate education conditional cash transfer programmes, often at a national scale.

    There is plenty of evidence showing that conditional cash transfers boost enrolment. But evidence on their impacts on children’s learning is mixed. Explanations for the lack of learning gains relate to the short-term nature of the evaluations, which may not provide enough time for the learning effects to materialise.

    In recent research, conducted in Morocco, we show that conditional cash transfers can constrain learning when no accompanying measures are taken by governments to account for increased enrolment. We found that the introduction of a programme can deteriorate school quality and thus constrain learning for children who enrol in school.

    Conditional cash transfers in Morocco

    We looked at a programme implemented at scale in Morocco. Known as Tayssir, it began operating in 2008 and quickly became the flagship education policy of a government strongly committed to reducing school dropout rates.

    Earlier research showed that the pilot version of Tayssir had substantial positive effects on enrolment, but not on learning.

    Following this evaluation, Tayssir was quickly scaled-up to reach annually up to 800,000 children in 434 municipalities. Because the allocation of transfers remained remarkably stable over time, the scaled-up version of Tayssir offers an ideal setup to study how conditional cash transfer programmes affect learning, with enough time for the effects to materialise.

    Tayssir targeted all municipalities with a poverty rate above 30% and all households with children aged 6-15 within these municipalities.

    To study the impacts of the programme, we used data from the information system of Morocco’s ministry of education.

    In the first part of our analysis, we assessed Tayssir’s effects on dropout rates and checked for possible differences with the research done in 2015 on the pilot version of the scheme.

    We confirmed that the grade-specific dropout rate decreased by 1.3 percentage points on average (41% of the sample mean). This is equivalent to an increase in enrolment of about 9 percentage points by the end of grade 6.

    We found a greater decrease for girls: 1.8 percentage points, or 50% of the sample mean.

    Remarkably, these estimates were in line with those on the pilot, despite the nationwide expansion of the programme and the ten-fold increase in the number of beneficiaries.

    The impact on quality

    The reduction of the dropout rates induced by Tayssir may have affected both class size and class composition by retaining lower-ability students. This could potentially lead to negative effects on learning outcomes through peer effects and less effective teaching practices.

    Our estimates show that class size in targeted areas increased by 3.6 students by the end of primary school, equivalent to 12% of the sample mean.

    Variation in class composition increased by 0.30 standard deviations (SD) by the end of primary school.

    Figure 1 shows that these effects are stronger in higher grades. This suggests that the reduction in dropout rates accumulated over time and progressively overburdened school resources. Large effects in grade 1 likely reflect the fact that children in targeted municipalities started school earlier – possibly to benefit from the transfers – and repeated grade 1 more often.

    Figure 1: Effect of Tayssir on class size and heterogeneity

    Notes: Each bar reports the coefficient estimate of the local average treatment effects of Tayssir. The dependent variables are class size (number of students per class) and class heterogeneity (standard deviation of the GPAs within a class). 95% confidence intervals are reported.

    Larger class sizes and increased differences in class composition had negative impacts on children’s test scores.

    In the final part of our analysis, we looked at the effects on test scores at the end of primary school exam. We found that Tayssir had negative effects on test scores. We estimated that the programme reduced test scores by 0.12 standard deviation for the full sample.

    What needs to be done

    Our insights should not be interpreted as evidence that policymakers should not pursue conditional cash transfer programmes. Such programmes, including the one we study, have proven particularly effective at increasing access to education, which is a crucial first step to enhance learning.

    These programmes also have many other benefits. These include delayed marriage and childbearing for adolescent girls.

    However, our results, together with evidence showing alarmingly low literacy and numeracy levels among students in low- and middle-income countries, indicate that the attendance gains from the programmes alone are unlikely to equip students with the foundational skills they need to thrive.

    In fact, our results show that conditional cash transfer programmes can have adverse effects on learning when schools lack the necessary resources to accommodate the influx of new students. Such insights may be particularly relevant for other interventions aiming to increase school attendance without complementary investments in school capacity.

    Recent decades have seen a surge in evaluations focusing on the learning effects of education interventions in low- and middle-income countries. Although there is no silver bullet to raise learning, some “great buys” emerged from the 2023 report of the Global Education Evidence Advisory Panel:

    • providing information on the benefits, costs and quality of education;

    • supporting teachers with structured pedagogy;

    • pedagogical interventions that tailor teaching to student learning.

    In Morocco, where our study takes place, other scholars have demonstrated that an intervention combining two of these three “great buys” – targeted instruction based on learning level and structured pedagogy – yields large gains in learning.

  • MIL-OSI Submissions: For Jane Austen and her heroines, walking was more than a pastime – it was a form of resistance

    Source: The Conversation – UK – By Nada Saadaoui, PhD Candidate in English Literature, University of Cumbria

    In Pride and Prejudice (1813), when heroine Elizabeth Bennet arrives at Netherfield Park with “her petticoat six inches deep in mud”, she walks not only through the fields of Hertfordshire, but into one of literature’s most memorable images of women’s independence.

    Her decision to walk alone, “above her ankles in dirt”, is met with horror. “What could she mean by it?” sneers Miss Bingley. “It seems to me to show an abominable sort of conceited independence.” And yet, in that walk – unaccompanied, unfashionable, unbothered – Elizabeth reveals more about her spirit and autonomy than any parlour conversation could.

    For Austen’s heroines, independence – however “abominable” – often begins on foot. Elizabeth may be the most iconic of Austen’s pedestrians, but she is far from alone. Across Austen’s novels, women are constantly in motion: walking through country lanes, walled gardens, shrubberies, city streets and seaside resorts.

    These are not idle excursions. They are socially legible acts, shaped by class, decorum, and gender – yet often quietly resistant to them.


    This article is part of a series commemorating the 250th anniversary of Jane Austen’s birth. Despite having published only six books, she is one of the best-known authors in history. These articles explore the legacy and life of this incredible writer.


    Fanny Price, the often underestimated heroine of Mansfield Park (1814), is typically seen as timid and passive. Yet beneath her reserved exterior lies a quiet but determined spirit.

    “She takes her own independent walk whenever she can”, remarks Mrs Norris disapprovingly. “She certainly has a little spirit of secrecy, and independence, and nonsense about her.” Austen’s choice of “nonsense” here is revealing: Fanny’s desire for solitude and self-direction is not revolutionary, but it is gently subversive. In a world offering women little room for self-assertion, her steps become acts of resistance.

    When Jane Fairfax, constrained by class and circumstance in Emma (1815), declines a carriage ride, she asserts: “I would rather walk … quick walking will refresh me.” It’s a seemingly modest decision, but one layered with significance. To walk is to control your own movement, to maintain autonomy and resist the genteel suffocation of being constantly observed or helped.

    In Persuasion (1817), Anne Elliot’s story shows walking as a path to renewal. Reserved and long burdened by regret, Anne finds restoration in the coastal air of Lyme Regis. As she walks along the Cobb, Austen notes that “she was looking remarkably well … having the bloom and freshness of youth restored by the fine wind … and by the animation of eye which it had also produced”.

    Her emotional reawakening is framed as a physical one. Walking becomes not only therapeutic but transformative – a way back to herself.

    Not all of Austen’s walks are reflective or restorative. Some are decidedly social. Lydia and Kitty Bennet’s frequent walks to Meryton in Pride and Prejudice, for example, are driven as much by shopping as by the hope of romantic encounters.

    Austen notes the “most convenient distance” of the village, where “their eyes were immediately wandering up in the street in quest of the officers”. These girls were more interested in uniforms than in bonnets.

    Yet even this behaviour hints at something subtler. For young, unmarried women, shopping and social errands were among the few socially sanctioned reasons to move independently through public space. These excursions offered moments of visibility, mobility, and the possibility of courtship – however frivolously pursued.

    Kitty and Lydia walk to Meryton in order to encounter the officers.

    Catherine Morland of Northanger Abbey (1817), a devoted reader of gothic fiction, fuses her walks with imagination. As she strolls along the Avon River with the Tilneys, she muses: “It always puts me in mind of the country that Emily and her father travelled through in The Mysteries of Udolpho.” Walking becomes an act of imaginative projection, where the boundaries between fiction and reality blur in the mind of a heroine learning to navigate both the world and herself.

    Jane Austen the walker

    Austen’s fiction draws much of its vitality from her own experiences. She was, by her own admission, a “desperate walker”, rarely deterred by weather, terrain or propriety.

    Wiki Commons

    Her letters, written from Bath, Steventon, Chawton and elsewhere, capture the physicality and pleasure of walking in vivid, often playful detail. These glimpses into her daily life reveal not only her attachment to movement but also the quiet autonomy it afforded her.

    In 1805, Austen writes from Bath: “Yesterday was a busy day with me, or at least with my feet & my stockings; I was walking almost all day long.” Several years later, in 1813, she reports with unmistakable relief: “I walked to Alton, & dirt excepted, found it delightful … before I set out we were visited by several callers, all of whom my mother was glad to see, & I very glad to escape.”

    Perhaps most revealing is an earlier letter from December 1798, in which Austen describes a rare solitary excursion: “I enjoyed the hard black frosts of last week very much, & one day while they lasted walked to Deane by myself. I do not know that I ever did such a thing in my life before.” The comment registers the novelty and boldness of a woman walking alone.

    In an age where walking is once again praised for its physical and mental benefits, Austen’s fiction reminds us that these virtues are not new. Her characters have been walking for centuries – through mud, across class boundaries and against expectation.

    They walk in pursuit of clarity, connection, escape and self-hood. Their steps – measured or impulsive, solitary or social – mark turning points in their lives. And in a world designed to keep them stationary, their walking remains a radical act.

  • MIL-OSI Submissions: Who owns digital data about you? South African legal scholar weighs up property and privacy rights

    Source: The Conversation – Africa (2) – By Donrich Thaldar, Professor, University of KwaZulu-Natal

    alexsl

    In the digital economy, data is more than just information – it is an asset with immense economic and strategic value. Yet, despite its significance, a fundamental legal question remains unresolved: Can data be owned? While privacy laws worldwide focus on protecting individuals’ rights over their personal data, they often sidestep the issue of ownership. This has led to legal uncertainty, particularly in South Africa, where the Protection of Personal Information Act (Popia) grants data subjects various rights over their personal information but does not explicitly address ownership.

    This gap in legal clarity raises pressing questions: If personal data – such as private health information – exists within a vast and ever-growing digital landscape, can it be owned? And if so, who holds the rightful claim?

    Legal academic Donrich Thaldar, whose research focuses on data governance, explores these questions in a recent academic article. He unpacks his findings for The Conversation Africa.

    Why does it matter who owns data?

    In today’s digital economy, data is the most valuable asset – it’s often referred to as “the new oil”. Whether in commerce, research, or social interactions, the ability to generate, use and trade with data is central to economic competitiveness.

    If data ownership is not clearly established, it could stifle innovation and investment. Companies require legal certainty to operate effectively in a knowledge-driven economy.

    Countries have taken different legal approaches to tackling the question of who owns data. China, for instance, formally recognises the proprietary rights of data generators, meaning that businesses and individuals who generate data have legally defined rights over its use and commercialisation. This provides legal support for the country’s digital industries.

    What does South African law say?

    In the past, the South African Information Regulator has taken the position that personal information is automatically owned by the data subject – the person to whom the data relates – rather than by the entity generating the data. In this view, the rights created by Popia imply that data subjects themselves are the owners of their personal data, and nobody else.

    I suggest that this stance is legally flawed, as it conflates two different branches of the law: privacy law and property law. Moreover, it could severely disrupt the digital economy. The digital economy depends on data as a tradeable asset – it must be capable of being sold, licensed and commercialised like any other economic object. If ownership must always be with data subjects, businesses face uncertainty in using and monetising data. Uncertainty stifles innovation, discourages investment, and undermines South Africa’s digital competitiveness.

    You applied property law to the question of data ownership. Why?

    Ownership is a concept in property law, not privacy law. Therefore, to answer the data ownership question, we need to look for answers in property law.

    Property law governs the relationship between subjects (legal persons) and objects (things external to the body, whether physical or not). Ownership is about the rights that a subject has over an object. For an object to be capable of being owned, it must be valuable, useful, and – importantly – capable of human control. A bottle of water meets these criteria, but the vast oceans do not, as they are not within human control.

    Personal data in the abstract is like the water in the ocean – vast, uncontained, and beyond individual control. However, a digital instance of personal data, such as a computer file, is more like a bottled version of that water – defined and subject to human control. Just like digital money and other valuable digital assets, a specific instance of personal data meets all the requirements under South African common law for private ownership. Thus, in this sense personal data can be owned.

    Is the data owner not the data subject?

    At first glance this might seem so, but no, not necessarily. The reason that it might seem so, is because some of the privacy rights created by Popia resemble ownership rights. For example, an owner’s agreement is required before someone else can use the owned object (e.g., loan for use and rent). Similarly, a data subject’s consent is in most cases required before personal data can be processed. Furthermore, the owner of a thing has the right to destroy it; similarly, a data subject typically has the right to have personal data deleted.

    Do these privacy rights mean that data subjects actually own their personal data? I suggest not. Wearing a feather in one’s hat does not make one a bird. In the same way, privacy rights that resemble ownership rights do not mean that they constitute ownership. Ownership is acquired by following the rules of property law.

    So who owns the data?

    Because a newly created personal data instance has no antecedent legal object – in other words, it is not created out of another legal object – it initially belongs to no one. It is res nullius. Ownership of res nullius is acquired through appropriation, which requires two elements: control and the intention to own.

    This means that the entity generating the data, such as a company or university collecting and recording it, is best positioned to acquire ownership. Since it already has control over the data, the only remaining requirement is simply the intention to be the owner.

    If an entity like a university generates data and intends to own it, then – provided it is in control of that data – it will legally become the owner. This in principle allows the entity to use, license and trade the data as an economic asset. Indeed, it is prudent for data-generating entities, such as universities, to explicitly assert ownership over the data they produce. This not only establishes their legal rights with clarity but also serves as a safeguard against unauthorised access and misuse by malicious actors.

    Doesn’t this compromise data privacy?

    No, it should not. Ownership is always limited by other legal rules. For example, while I might own a car, I cannot drive it in any way I like – I must obey the rules of the road. Similarly, ownership of personal data is subject to strict limitations, particularly the privacy rights of data subjects under Popia.

    However, it is also important to understand that privacy rights apply only to personal data. If personal data is de-identified, meaning that it can no longer be linked to the data subjects, privacy rights cease to apply. What remains are the ownership rights in the data itself. It can be a fully tradeable asset.

    Recognising that a digital instance of personal data can be owned – and that the rightful owner is typically the data generator – does not undermine the privacy protections of Popia. Rather, it clarifies the legal landscape, ensuring that the rights of both data subjects and data generators are recognised and protected.

  • MIL-OSI Submissions: Kids should be encouraged to talk back – 5 tips for teaching them critical thinking skills

    Teaching kids to think critically sets them up well for life. eli_asenova

    Whenever school holidays loom, many parents find themselves caught in an emotional tug-of-war: on the one hand, relief at bidding farewell to homework battles, bedtime struggles, and the lamenting of lost lunchboxes; on the other, terror at the daunting prospect of a barrage of “whys” and “buts” from their relentless interrogators. To avoid logic-defying arguments and endless debates, it is often not long before they find themselves playing the ultimate parental trump card: “because I said so”.

    As a parent, I can relate. But I’m also a moral philosopher with almost two decades of teaching experience. In philosophy classes, students who question ideas – and sometimes, in doing so, challenge authority – are praised. Why isn’t the same true for children? Is a child who questions their parents “being cheeky”? Or are they flexing the mental muscles that are necessary for their intellectual growth and ability to navigate the world?

    The job of a moral philosopher is to grapple with ideas about right and wrong, good and bad, seeking to answer the ultimate question: “how ought we to live?” While we use a range of strategies to tackle these fundamental ethical questions, one of the most important tools at our disposal is critical thinking.

    Critical thinking is the ability to analyse and evaluate information and arguments in a clear, rational and objective manner. When we are confronted with information, critical thinking requires us to consider why this person is saying that. What could be their motive? Is there a different possible explanation?

    I’m not suggesting that the goal is to raise argumentative children. Rather, as philosopher, strategic thinker and author Peter Facione explains, it is to nurture inquisitive minds that can interpret, analyse, evaluate and infer from information. In other words, parents should raise their children to be curious, critical thinkers who question everything, even if this means they question us in the process.

    How can parents teach critical thinking at home? Here are my five top tips:

    1. Ask open-ended questions and encourage children to do the same.

    2. Provide children with opportunities to make decisions and solve problems rather than doing it for them.

    3. Discuss the reasoning behind rules and decisions you make for them.

    4. Encourage children to consider alternative perspectives rather than just their own.

    5. Model critical thinking by thinking aloud when approaching problems.

    Thinking about our thinking

    Critical thinking requires metacognition: thinking about our thinking.

    Reflecting on our own views gives us a chance to recognise that they too should be scrutinised and evaluated. If we choose to be vegan, for example, is it because we care about reducing harm to animals, the environment, or both; or because it’s fashionable to be vegan? Once we’ve worked out our reasons for something, we can then evaluate whether these are “good” reasons or not.

    Critical thinking also means evaluating other people’s reasons. This requires us to be open to others’ points of view – including our children’s – rather than being blinded by our own biases. At the same time, to be a critical thinker is to take seriously the fact that everyone “has an agenda” (which may not be explicit) and we should therefore not take everything at face value. We can teach our children to be critical thinkers by getting them to consider the quality of the evidence presented for a position.

    Put simply, parents and caregivers can promote critical thinking in children by encouraging them to ask questions, challenge assumptions and explore alternative perspectives. Critical thinking requires us not to passively accept everything we read, hear and see but rather to question, evaluate and make judgments.

    Here’s what that might look like in practice.

    A practical example

    Add a side of critical thinking to make vegetables more palatable.
    FAMILY STOCK/Shutterstock

    Let’s say your child asks why she needs to eat vegetables.

    You could respond by saying “That’s a good question. What do you think? Why do you suppose we eat vegetables?” This encourages the child to start thinking about the issue herself.

    She replies: “Because you said I have to.”

    To get her to think about whether there are reasons beyond parental authority that may be important, you might want to ask: “Is that the only reason? Let’s think about it some more. Do you know anyone else who thinks we should eat vegetables?”

    Then, to encourage her to explore alternatives, you could ask: “What do you think would happen if we never ate any vegetables? What if we only ate sweets instead?”

    It might also be useful to do some research with your child, to introduce the idea of seeking evidence and reliable information. You could suggest that the two of you look up some facts about what vegetables do for our bodies.

    Finally, you could pose the original question back to your child, giving her a chance to synthesise what she’s learnt and form her own conclusion.

    Throughout the process, you are guiding your child to question, think about, and arrive at a reasoned understanding, rather than simply accepting a statement at face value.

    Other resources

    Does this sound daunting? Relax – it’s not all up to you.

    Many schools incorporate critical thinking skills across their curricula. Some excellent programmes have been implemented in schools around the world. One example is Philosophy for Children (P4C), developed by educator and philosopher Matthew Lipman in the 1970s. This approach uses structured discussions about open-ended questions and can be used to develop critical thinking skills in children as young as six.

    I also like the work of Critical Thinking Consortium (TC2), a Canadian organisation which provides resources and professional development to help educators embed critical thinking in their teaching. Project Zero is another good resource. This research group at the Harvard Graduate School of Education has developed several thinking routines and frameworks, such as “visible thinking” and “artful thinking”.

    You could also advocate for your child’s school to introduce critical thinking skills into their curricula. Schools could partner with university philosophy departments to offer classes for low or no cost as a community engagement or social responsibility initiative.

    Ultimately, whether children are exposed to these skills at home or at school, the key is to create an environment where questioning, reasoning, and exploring ideas are encouraged and valued. The goal is to make critical thinking a natural part of the way we interact with our children so that it becomes a natural part of the way they interact with the world.

  • MIL-OSI Submissions: Five ways you can use mantra meditation every day to boost your wellbeing

    Source: The Conversation – UK – By Jennifer Donnelly, Doctoral Researcher, Meditation-based Interventions in Clinical Settings, Centre of Positive Health Sciences, RCSI University of Medicine and Health Sciences

    Meditation has become a popular subject on self-improvement podcasts, corporate strategy days and health campaigns. But beyond the buzz, there’s a growing scientific and clinical interest in meditation as a tool to regulate attention and promote relaxation. These are increasingly recognised as central to wellbeing in a world of constant notifications, high demands and information overload.

    Mantra meditation has roots in ancient contemplative traditions across many cultures. At its simplest, a mantra is a word, phrase, or sound repeated silently or aloud to focus the mind, steady attention and support relaxation. Depending on the tradition, mantras may carry deep spiritual, linguistic or energetic significance. But in a more personal or secular practice, you might choose or create a mantra that’s meaningful only to you.

    It’s important to note that mantra meditation is distinct from focusing on breathing. While both help develop concentration and awareness, the mantra, not the breath, is the primary anchor of attention in mantra meditation. You may notice the breathing naturally while meditating, but the repetition of the mantra is what gently draws your mind back when it wanders.

    Emerging research suggests that mantra meditation may have promising benefits, from reducing stress and burnout to improving mood, focus and sleep. Focusing on a mantra to disengage from an overactive mind can be a valuable tool in today’s fast-paced world.

    Mantra meditations moments

    A simple starting point is to choose a phrase that resonates with you, something easy to remember and calming. For example: “I am … here now.” Or a word like “ease” or “peace”. Some people visualise a calming image, like a steady tree or a gentle wave, repeating it silently in their mind. The key is to return to your chosen anchor, your mantra, each time your mind drifts.

    You don’t need a special cushion, app or ritual. Below are five everyday moments when you can try this light mantra-practice:

    • On public transport: Use a few minutes of your commute to mentally repeat your mantra. The surrounding noise and movement can actually enhance the practice. When your mind wanders, which it will, gently return to your anchor.

    • While brushing your teeth: This brief, repetitive activity is already part of your day. Use the rhythm of brushing as a cue to repeat your mantra internally.

    • During your first sips of tea or coffee: Let this be a pause point. Breathe naturally. Repeat your chosen phrase. Even a few seconds of presence can shift the tone of your morning.

    Your first morning coffee could become a moment of deep calm in an otherwise hectic day.

    • Instead of scrolling: Replace one moment of habitual phone use with one minute of mantra repetition. Notice the impulse to scroll, and meet it with your mantra instead. You can scroll later if you want; the point is to notice the choice.

    • Before stepping out of the car: Pause for 30-60 seconds before entering a new environment, whether that’s work, home or a social setting. This brief ritual can be a surprisingly powerful reset when transitioning to a new destination or activity.

    Longer sessions may deepen the effects, but short, consistent moments of practice are what build tolerance and insight. Meditation doesn’t always begin with peace. More often, it starts with the uncomfortable awareness of how distracted our thoughts can become. That moment of noticing is not a failure, it’s the practice.

    For parents, especially those with young children, meditation might feel unrealistic. But mantra practice can be adapted. Children often respond well to repetitive, rhythmic exercises. Try counting fingers together, repeating a calming phrase, or simply taking three breaths. It might not look like traditional meditation, but it can still create a shared moment of calm.

    Even counting fingers with children could be a way to experience a moment of togetherness and calm.
    YAKOBCHUK VIACHESLAV/Shutterstock

    For those living with chronic pain, health challenges or intense life transitions, meditation can sometimes make discomfort feel more present. In such cases, stillness might initially increase distress.

    Some research confirms that meditation can have uncomfortable or adverse effects, and distraction may be necessary at times. Even so, carefully introduced mantra meditation techniques or similar practices may support people living with chronic conditions by helping shift how discomfort is experienced, if approached with care, and suitable supports are offered.

    Mantra meditation isn’t about perfect focus, or fixing all our problems. Its strength lies in offering you a portable, repeatable practice to build awareness, one moment at a time.

    So before you move on after reading, try this: take 30 seconds, close your eyes, and return to your mantra. Just for now.

  • MIL-OSI Submissions: What one university’s 30-year transformation reveals about Afrikaans and language planning in South Africa

    Source: The Conversation – Africa – By Lloyd Hill, Lecturer, Stellenbosch University

    Rodger Bosch/AFP via Getty Images

    When South Africa became a democracy in 1994, five of the country’s universities used Afrikaans as a medium of instruction. There were also two bilingual universities teaching in Afrikaans and English.

    Stellenbosch University, about 50km from Cape Town, is the oldest historically Afrikaans university. Over the past three decades English has gradually replaced Afrikaans in the core functions of teaching and research.

    The status of Afrikaans at formerly Afrikaans or bilingual universities remains the subject of considerable debate. This has led to litigation and three judgments in South Africa’s apex court, the constitutional court.

    Afrikaans is commonly categorised as an Indo-European language, related to Dutch. It can be more accurately described as a Creole language that developed after the Dutch colonised the Cape in 1652. In 1925, standardised Afrikaans became an official language alongside English. It subsequently became associated with white Afrikaner nationalism and, from 1948, apartheid education policies. In 1976, Black students mobilised against attempts to make Afrikaans a compulsory medium of instruction in schools.

    I’m a sociologist who studies language and communication in science and higher education. In a recent article and presentation I examined the three phases in which the language shift and the decline of Afrikaans at Stellenbosch University has unfolded.

    The first phase (1994-2002) involved an attempt to defend Afrikaans institutional monolingualism. The second (2002-2015) saw a shift to institutional bilingualism. Afrikaans and English were used in undergraduate classes. The final and current phase began with the 2015-16 #FeesMustFall student protests. Pressure for the transformation of a predominantly white campus escalated. This triggered a rapid shift to English.

    In 2024, the university’s language policy is, on paper, a scaled-down version of institutional bilingualism (Afrikaans and English). However, in practice English is the main medium of instruction. Afrikaans is, increasingly, not used across all disciplines. This reflects the trend at other formerly Afrikaans or bilingual public universities.

    There is a case to be made for defending Stellenbosch University’s position as a centre of Afrikaans language and culture. But the centralised language planning apparatus it has developed over the past two decades is simply unsustainable. This case study prompts a broader reflection on languages and language planning within South African higher education.

    First, for reasons related to its global academic status and its national second-language status, English has emerged as the dominant language of teaching and research at South African universities.

    The second issue has to do with the nature of “language” at different levels of the education system. The official languages adopted in 1994 are not uniform “mother tongues” or “vehicles” moving from basic education to PhD.

    Languages are more than individual “competencies”: they are political and economic projects. They are also particularly expensive and difficult to “plan” in university teaching and research.

    First phase (1994-2002)

    In 1994, South Africa’s then-interim constitution recognised 11 official languages. It committed “the state” to “practical and positive measures to elevate the status and advance the use of these languages”.

    Afrikaans universities faced a particular dilemma. How could they retain Afrikaans as a medium of instruction and open enrolment to formerly excluded Black students? These are generally second-language English speakers who opt to study in English.

    Other historically Afrikaans institutions adopted parallel medium instruction. Stellenbosch University resisted this trend and asserted its autonomy as a monolingual institution. Postgraduate teaching and research, however, shifted to English. Afrikaans was reframed as an undergraduate teaching issue.

    The university argued that the predominantly Afrikaans-speaking Western Cape and Northern Cape provinces needed an Afrikaans-medium university.

    Two factors undermined this demographic argument. First, the university enjoys national status. This can be traced back to an elite Anglophone college system in the 19th century British Cape Colony. Second, after the 1994 transition, the university focused on internationalisation. It also established itself as a leading research-intensive institution. As a result it has increasingly attracted students and academics with little or no Afrikaans competency.

    Second phase (2002-2015)

    In the early 2000s South Africa’s higher education system was overhauled. This involved institutional mergers, which coincided with the adoption of the 2002 Language Policy for Higher Education. The policy effectively disestablished monolingual Afrikaans universities, stating:

    The notion of Afrikaans universities runs counter to the end goal of a transformed higher education system.

    Stellenbosch University adopted its first language policy and plan in 2002. Afrikaans was reframed as one of four undergraduate language options and described as “the default language of undergraduate learning and instruction”. A heated debate erupted in the Afrikaans media. In this first public – and acrimonious – taaldebat (language debate) many criticised the new “default” status of Afrikaans. That’s because, like a default setting on a computer, this option could be switched.

    The new policy introduced formal language planning as an institutional process that would involve periodic policy updates. It also presented three module “options” that represented possible routes away from institutional monolingualism.

    First, dual medium instruction involved using both English and Afrikaans in one lecture. Second, parallel medium instruction involved separate lectures in English and Afrikaans. Third was an English medium option. However, the second and third options were reserved for “exceptional circumstances”.

    Within a few years, most modules shifted to the dual medium option. The university shifted to a dual medium form of institutional bilingualism. But a tacit racial assumption underpinned this model. The language policy ignored the growing enrolment of Black students and the appointment of Black staff members who didn’t have the required bilingual proficiency.

    A new language policy, adopted in December 2014, tried to address the bilingual proficiency problem. It prioritised parallel medium instruction and “educational interpeting”. It never got off the ground.

    Third phase (2015 to date)

    Beginning in March 2015, a series of “Fallist” movements mobilised on South African campuses. A predominantly Black student movement called Open Stellenbosch was established. It aimed “to challenge the hegemony of white Afrikaans culture and the exclusion of Black students and staff”. Language policy was a key point of contention.

    The university responded by redrafting its language policy. In June 2016 it established English as the primary medium of teaching at the undergraduate level.

    This moment also marks the shift to what I term the second taaldebat. Afrikaans language activists now argued that English and Afrikaans ought to enjoy equal status. Institutional bilingualism became the new ideal framework for defending Afrikaans at Stellenbosch University.

    Language activism included litigation, which ended in a constitutional court ruling. The court upheld the 2016 language policy review process. It also noted the “hard racial edge” to the evidence produced by Stellenbosch University. It remarked that:

    Seen as a bloc, the new entrants for whom Afrikaans is an obstruction are not brown or white, but overwhelmingly Black.

    Today, Stellenbosch remains notionally committed to “multilingualism”. In practice, this means a scaled down version of institutional bilingualism. It involves very limited parallel medium instruction and some simultaneous interpreting. English is the compulsory medium in modules where no duplication occurs.

  • MIL-OSI Submissions: Scientists in Antarctica: why they’re there and what they’ve found

    Source: The Conversation – Africa (2) – By David William Hedding, Professor in Geography, University of South Africa

    A media storm blew up in mid-March 2025 when a researcher at South Africa’s isolated Sanae IV base in Antarctica accused one of its nine team members of becoming violent.

    The Conversation Africa asked geomorphologist David William Hedding, who has previously carried out research from the frozen continent, about the work researchers do in Antarctica, what conditions are like and why it matters.

    What do researchers focus on when they’re working in Antarctica?

    Currently, the main focus of research in the Antarctic revolves around climate change because the White Continent is a good barometer for changes in global cycles. It has a unique and fragile environment. It’s an extreme climate which makes it highly sensitive to any changes in global climate and atmospheric conditions. Importantly, the Antarctic remains relatively untouched by humans, so we are able to study processes and responses of natural systems.

    Also, the geographic location of Antarctic enables science that is less suitable elsewhere on the planet. An example of this is the work on space weather (primarily disturbances to the Earth’s magnetic field caused by solar activity). Studying space weather is significant because the magnetic field of the Earth can impact communication platforms, technology, infrastructure and even human health.

    How many countries have teams working there? Where does South Africa fit in?

    Currently, about 30 countries have research stations in the Antarctic but these bases serve a far wider community of researchers. Collaboration is a key component of research in the Antarctic because many study sites are isolated, logistics are a challenge and resources are typically limited.

    The South African base in Antarctica, named SANAE IV usually has between 10 and 12 researchers and base personnel. This research station is situated on a nunatak (a mountain piercing through the ice) in Western Dronning Maud Land. It is an extremely remote location approximately 220km inland from the ice-shelf.

    The researchers and base personnel remain in Antarctica for approximately 15 months working through the cold and dark winter months.

    What have been some of the biggest ‘finds’?

    The biggest research finding from the Antarctic was the discovery of the ozone hole in 1985 by scientists from the British Antarctic Survey. This discovery led to the creation and implementation of the Montreal Protocol, a treaty to phase out chlorofluorocarbons (synthetic chemical compounds composed of chlorine, fluorine, and carbon) which destroy ozone. This was a major breakthrough in terms of slowly healing the ozone layer.

    The second most significant piece of research to come from the Antarctic has been the use of ice cores to reconstruct past climates. Ice cores preserve air bubbles which provide a wealth of information about the conditions of the atmosphere over time. Importantly, ice cores provide an uninterrupted and detailed window into the past 1.2 million years. This is important because only by understanding past climates and the earth’s responses to those changes are we able to predict future responses. This is significant because of the imminent threats resulting from anthropogenic (human-induced) climate change.

    What conditions do scientists work under?

    Conducting research in the Antarctic is extremely difficult for three primary reasons: remoteness, the cold and daylight.

    The remoteness of many study sites makes it difficult to reach. Distances are vast from the limited number of bases in the Antarctic. Thus, logistics for science in the Antarctic is a major challenge and requires collaboration and planning. For example, the geologists from the University of Johannesburg, who work from the SANAE IV base in Antarctica, often spend weeks in the field collecting samples. They travel significant distances via snow mobile and remain self-sufficient while conducting science in tough conditions.

    These tough conditions relate specifically to the cold. Most science only occurs in the austral summer months when temperatures become marginally bearable. Also, the summer season only provides a short window in which to operate because access to Antarctic by sea is limited by extent and thickness of the sea ice.

    Lastly, during summer there is 24 hours of daylight which lengthens the working day but these conditions are also short-lived.

    Why it is important to do scientific work in the area?

    The Antarctic is intricately linked to global systems and plays a major role in influencing these systems.

    For example, climate change will cause significant melting of land-based ice in Antarctica which when added to the oceans will cause sea-level rise and disruptions to global oceanic currents. Therefore, it is critical that we obtain a better understanding of how responses of terrestrial systems, such as the Antarctic, will impact oceanic systems because ultimately changes in ocean currents will impact the oceanic food web.

    In the context of climate change, sea-level rise is a major concern as it will have global impacts for society, so it is critical that the impacts are investigated to enable society to build resilience and adapt.

  • MIL-OSI Submissions: How huge migrating animal puppets captivate in ways that climate news can’t

    Source: The Conversation – UK – By Matt Smith, Reader in Applied Theatre and Puppetry, University of Portsmouth

    A herd of puppet animals is migrating north from Africa. This 12,000 mile journey represents wildlife’s response to the climate crisis as species are forced to move north due to rising temperatures. As The Herds travels through the UK en route to the Arctic, the organisers hope this artistic project will help spectators along the route understand what is happening to the environment.

    Events like this are “louder than traffic”, according to US-based puppeteer Peter Schumann. The giant puppets are a visual tool to capture the public’s imagination.

    Over the past 30 years working as a theatre scholar, I have observed that puppetry has become an important artform for telling stories that explore the way we respond to and interact with nature.

    Like traditional street theatre such as Punch and Judy, puppets grab the audience’s attention against the backdrop of everyday life. Now with the rise of social media, modern culture is now even more visually oriented. Puppetry is a big hit in these new digital spaces, according to some researchers.

    The Herds project was created by a theatre company called Little Walk after the success of Little Amal, a Syrian refugee puppet project about human migration and climate relocation. One of the Little Amal puppeteers told me that, ironically, it was easier for the puppets to cross borders but the human artists and puppeteers had to take major detours to carry out the Little Amal project in 17 countries.

    The Herds aims to inspire people to think about the direct consequences of the climate crisis as the animal puppets travel from Africa to the Arctic. Puppeteers animate the life-size puppets in full view of the audience. As each puppeteer focuses on moving the puppet, they transfer their energy and emotion into the puppets body.

    The Herds takes puppets on a 12,000-mile-long migration from Africa to the Arctic.

    I was trained in these techniques during the 1990s. I know that when a performer intensely focuses on a performing object, the result is mesmerising. It can enable the audience to feel empathy for another non-human being. The aim is to cut through discourses and affect people directly with images performed beyond language and local agendas.

    Puppetry is both an interdisciplinary and interactive artform that is as old as human culture. Animated figures have been employed in both the popular spaces of folk theatres and the avant garde spaces of high art. Puppet characters can tell very simple stories in slapstick shows or speak to complex issues in projects like The Herds.

    Even having researched puppetry in communities for more than three decades, the many varied uses for puppetry continue to surprise me. Beyond theatres, puppets can affect people in everyday spaces, just as The Herds does. My book, published in 2024, explores how the popular global practice of puppetry by communities and groups brings pleasure through both making and performing with puppets.

    Communicating complexity

    In 2023, I collaborated with scientists at the Centre for Enzyme Innovation at University of Portsmouth who are developing enzymes that can break down plastic waste. We found that puppets could help to communicate complex science about innovative recycling to audiences through workshops and a showcase event. The puppets as entertaining figures symbolising ideas could animate the science and engage audiences in a playful and non-elitist fashion.

    Puppetry is a powerful and engaging art form that can capture the imagination of audiences globally. Even during our advanced technological times puppetry is still employed both by technologies – for example our own XR lab used puppets recently exploring their use with avatars.

    With successful West End productions in London such as Lion King and War Horse (a show which changed the fortunes of the National Theatre, puppetry has become mainstream in the UK. Now with The Herds, animal puppets are having a global reach.

    A herd of puppet animals is migrating north from Africa. This 12,000 mile journey represents wildlife’s response to the climate crisis as species are forced to move north due to rising temperatures. As The Herds travels through the UK en route to the Arctic, the organisers hope this artistic project will help spectators along the route understand what is happening to the environment.

    Events like this are “louder than traffic”, according to US-based puppeteer Peter Schumann. The giant puppets are a visual tool to capture the public’s imagination.

    Over the past 30 years working as a theatre scholar, I have observed that puppetry has become an important artform for telling stories that explore the way we respond to and interact with nature.

    Like traditional street theatre such as Punch and Judy, puppets grab the audience’s attention against the backdrop of everyday life. Now with the rise of social media, modern culture is now even more visually oriented. Puppetry is a big hit in these new digital spaces, according to some researchers.

  • MIL-OSI Submissions: African countries need more PhD graduates but students are held back by a lack of money and support

    Over the past 15 years there’s been an increasing demand from within and outside the higher education sector for African countries to produce more PhD graduates. For this to happen, it’s important to know what’s holding people back from pursuing or completing their doctoral degrees. The authors of a new review article did just that, with a focus on South Africa, Kenya, Ethiopia, Uganda and Nigeria. Five themes emerged from their work: PhD candidates’ sociodemographic profiles, access to funding, the availability of resources and training, experiences with PhD supervisors, and personal coping mechanisms.

    The Conversation Africa spoke with the paper’s authors, Oluwatomilayo Omoya, Udeme Samuel Jacob, Olumide A. Odeyemi and Omowale A. Odeyemi, to learn more about their findings.

    Why is it important for African countries to produce PhD graduates?

    PhD programmes have been shown to play a crucial role in advancing research, innovation, and economic and scientific progress.

    That’s because the more research capacity a country has, the more likely it will be able to address gaps in healthcare, economic barriers and food insecurity. This point has been emphasised by, among others, the World Health Organization (WHO) and the African Union.

    Doctoral education builds academic expertise. This drives growth across multiple sectors, such as health, education and technology. It also fosters an environment where creative and practical solutions to local challenges can thrive.

    What are some of the main obstacles PhD students faced in the countries you studied?

    Our study was a scoping review. This research method allowed us to broadly survey existing studies and identify key concepts, evidence types and knowledge gaps. The review included articles from different African countries, among them South Africa, Kenya, Ethiopia, Uganda and Nigeria.

    One of the biggest hurdles we identified for PhD students is a lack of resources. Many of the continent’s universities are underfunded. They struggle to offer their staff and students adequate research facilities, libraries and even internet access.

    Another major challenge is the shortage of quality doctoral supervision. In many African universities, the number of qualified supervisors is far lower than the number of doctoral candidates. This imbalance means that some students receive little attention. Their progress may suffer as a result.

    A PhD is, by nature, a solitary pursuit. But without the proper support, students can feel disconnected from the academic community. This sense of isolation can increase dropout rates and hinder the completion of research projects.

    South African universities need to better support doctoral supervisors


    Supervisors are frequently overwhelmed with other responsibilities – their own research, administrative duties, or teaching large undergraduate classes. This leaves them with limited time to mentor PhD students. The students they’re tasked with supervising can end up feeling isolated.

    Personal funding is also hard to come by. Scholarships are rare and, when they are available, they don’t always cover all the student’s expenses over the course of their research. Many students must work full-time jobs to support themselves while pursuing their doctorate. This can severely affect their ability to dedicate time to their studies.

    Even in cases where funding is available, it’s often linked to short-term projects or grants that don’t allow students to finish their research without interruption. This leads to long delays in graduation rates, which creates a bottleneck effect: students remain stuck in the system for years, clogging the flow of new researchers entering academia.

    PhDs are important for South Africa’s growth: more support for doctoral candidates who work full-time is key


    Another challenge is that African doctoral students who do succeed may leave their home countries for better opportunities abroad. The so-called “brain drain” phenomenon has a profound effect on Africa’s ability to build a strong academic community. While many African PhD students go on to do groundbreaking research in Europe, North America or Asia, their departure means their home institutions – and countries – lose valuable knowledge and experience.

    Brain drain is not just about better salaries or living conditions; it’s also about the availability of cutting-edge research opportunities. Once abroad, many students are able to access better resources and then choose to stay in environments that allow them to thrive professionally.

    What role does gender play in the likelihood of completing a PhD?

    Women pursuing PhDs face additional challenges that their male peers do not. We found that women PhD students frequently face gender biases, both socially and professionally, that make it harder to fulfil their academic goals.

    Over the past decade, the number of women enrolling in PhD training in some countries, such as Ethiopia and South Africa, has increased.

    However, women are less likely than men to complete their doctoral studies, partly because of the cultural expectations and responsibilities they bear. Female students who are married or have children must often balance managing their households and care-giving responsibilities with pursuing their studies.

    In regions where family is traditionally prioritised over career aspirations, women may feel an added layer of guilt or societal pressure, which can lessen the time they have to focus on research.

    Moreover, in areas where colonial or apartheid legacies still influence societal structures, Black women in particular report additional barriers. They say they feel overlooked or underestimated in academic spaces.

    There has been some progress. Organisations like the Consortium for Advanced Research Training in Africa (Carta) offer programmes that support women throughout their academic journeys. However, a greater, gender-responsive approach is needed to ensure that women have access to resources, mentorship and flexible support systems that address these unique challenges.

    Increasing support for women in PhD programmes isn’t just about numbers. It means institutions and the wider society must address the structural and cultural barriers that hold women back.

    Are there solutions to the issues you’ve identified?

    The challenges facing doctoral students in Africa are complex, but not impossible to overcome.

    With the right investments and a commitment to reform, universities on the continent can grow into global centres of excellence in research and development. It’s vital for societies not to lose sight of the importance of higher education. As we’ve said, and as a large body of evidence shows, strong doctoral training programmes and investing in research and innovation to address the challenges faced by the African continent are key to ensuring that the next generation of researchers and innovators can lead the way in solving some of the world’s most pressing problems.

    Governments, universities and funding organisations can collaborate by providing scholarships and research grants, creating gender equality policies, and introducing mentorship programmes or improving those that already exist.

  • MIL-OSI Submissions: 1.5 million-year-old bone tools discovered in Tanzania rewrite the history of human evolution

    Source: The Conversation – Africa (2) – By Jackson K. Njau, Associate professor, Indiana University

    The ancestors of humans started making tools about 3.3 million years ago. First they made them out of stone, then they switched to bone as a raw material. Until recently, the earliest clear evidence of bone tool making was from sites in Europe, dated to 400,000 years ago. But archaeologists have now found and dated bone tools in Tanzania that are a million years older.

    The tools are made from the bones of large animals like hippos and elephants, and have been deliberately shaped to make them useful for butchering large carcasses.

    The discovery of bone implements that are the oldest ever found, by far, casts light on human evolution. It shows that our hominin ancestors were able to think about and make this technology a lot earlier than anyone realised.

    I am a scientist who co-directs a multidisciplinary research project team at the Olduvai Gorge in Tanzania, focusing on hominin evolution. Our project’s main goal has been to investigate the changes in hominin technology and behaviour that happened between 1.66 million and 1.4 million years ago.

    We’re interested in this time period because it marks a pivotal change in human technology, from the rudimentary stone knives and cores of the Oldowan culture to the more advanced crafted stone handaxes of the Acheulean culture.

    We found the Olduvai bone tools in 2018 and recently described them in the journal Nature. They show that by 1.5 million years ago, our ancestors (Homo erectus) had already developed the cognitive abilities required to transfer skills from making stone tools to making bone tools.

    This leap in human history was a game-changer because it allowed early hominins to overcome survival challenges in landscapes where suitable stone materials were scarce.

    Tools at Olduvai

    Olduvai Gorge is a Unesco World Heritage site. It became well known in 1959 through the pioneering work of palaeontologists Louis and Mary Leakey, whose discoveries of early human remains reshaped our understanding of human evolution. The site offers an unparalleled window into human history, spanning nearly 2 million years.

    Finds in Tanzania’s Olduvai Gorge reveal how ancient humans adapted to change


    Aside from fossilised bones, it has yielded the most detailed record of stone tool cultures in the world. It has documented the evolution from the simple chopping tools and stone knives of the Oldowan industry (about 2 million years ago) to the more advanced Acheulean tools (1.7 million years ago), such as handaxes, cleavers, picks and spheroids and then on – through arrowheads, points and blades (about 200,000 years ago) to the micro-blades of the Later Stone Age (about 17,000 years ago).

    All these tools provide a glimpse into the ingenuity and cultural advancements of our early ancestors.

    And now the picture has new detail.

    Our team uncovered 27 ancient bone tools during excavations at the T69 Complex, FLK West site at Olduvai. We know how old they are because we found them securely embedded underground where they had been left 1.5 million years ago, along with thousands of stone artefacts and fossilised bones. We dated them using geochronological techniques.

    Unlike stone, bone shafts crack and break in a way that allows the systematic production of elongated, well-shaped artifacts. Flaking them by hitting them with another object – a process called knapping – results in pointed tools that would be ideal for butchering, chopping and other tasks.

    The knapped tools we found were made from large shaft fragments that came from the limb bones of elephants and hippos, and were found at hippo butchery sites. Hominins likely brought elephant bones to the site on a regular basis, and obtained limb bones from butchered hippos at the site itself.

    What Homo erectus knew

    The find shows that 1.5 million years ago, Homo erectus could apply knapping skills to bone. Homo erectus, regarded as the evolutionary successor to the smaller-brained Homo habilis, left a lasting imprint on history. Its fossils, found at Olduvai, offer a glimpse into a span of about a million years, stretching from 1.5 million to roughly 500,000 years ago.

    Now we know that these hominins not only understood the physical properties of bones but also knew about skeletal anatomy. They could identify and select bones suitable for flaking. And they knew which animals had skeletons large enough to craft reliable tools after the animals’ death.

    Large mammals shaped the evolution of humans: here’s why it happened in Africa


    We don’t know exactly why they chose bones as a raw material. It may have been that suitable stone material was scarce, or they recognised that bones provided a better grip and were more durable.

    Why haven’t such old bone tools been found before? The answer is likely that they are destroyed by weathering, abrasion from water transport, trampling and scavenger activity. Organic materials don’t always get time to fossilise. Also, analysts were not used to looking for bone tools among fossils.

    This discovery will likely encourage researchers to pay closer attention to the subtle signs of bone knapping in fossil assemblages. This way we will learn more about the evolution of human technology and behaviour.

  • MIL-OSI Submissions: Labour is divided over disability cuts – here’s what the public thinks

    Keir Starmer has been dealing with his most serious parliamentary challenge since he became prime minister. More than a hundred Labour MPs backed a motion to stop in its tracks the government’s attempt to reduce the welfare bill, including by raising the threshold at which someone can claim disability benefit.

    This issue has divided the parliamentary Labour party. But what does the public think?

    Although there are signs people recognise that spending on disability benefits is now relatively high, the latest annual British Social Attitudes (BSA) report reveals that it is far from clear that they are supportive of cutbacks. And, unfortunately for the government this is especially true of those who voted Labour last year.

    Ever since the late 1990s, BSA has regularly asked its respondents whether they would like “to see more or less government spending than now on benefits for disabled people who cannot work”. In 1998, 78% indicated they would like to see more spending. By 2011, that figure had fallen to 53%, and it was still no more than 56% in 2021.

    Now, though, only 45% would like to see more money spent on disability benefits. For the first time, less than half the country backs giving those with a disability more help.

    However, that does not mean most voters would like to see actual cutbacks. Only 11% say the government should spend less on disability benefits. The rest are content with the status quo.

    Meanwhile, just 5% of those who voted Labour last year back less spending. Over half (53%) are in favour of an increase.

    The government’s central argument is that it has become too easy to claim disability benefits and that this is discouraging people from getting back into employment.

    There is some support for this view. Among the public in general, 29% say it is “too easy” to claim disability benefit. The trouble is, just as many, 29%, take the opposite view and say it is “too difficult”. The most popular response, given by 35%, is that it is “neither too easy nor too difficult”.

    Meanwhile, among Labour voters, the balance of opinion is clearly tilted towards the view that claiming disability benefit is “too difficult”. As many as 39% say so, while only 20% feel it is “too easy”.

    Similarly, most voters (62%) feel the requirement for people on disability benefits to take “active measures to find appropriate work” is “about right”. Just 11% feel it is “too weak”, while more than twice as many (23%) believe it is “too tough”. Only 6% of Labour voters believe it is “too weak”.

  • MIL-OSI Submissions: First fossil hyena tracks found in South Africa – how expert animal trackers helped

    Source: The Conversation – Africa (2) – By Charles Helm, Research Associate, African Centre for Coastal Palaeoscience, Nelson Mandela University

    “The art of tracking may well be the origin of science.” This is the departure point for a 2013 book by Louis Liebenberg, co-founder of an organisation devoted to environmental monitoring.

    The connection between tracking in nature, as people have done since prehistory, and “western” science is of special interest to us as ichnologists. (Ichnology is the study of tracks and traces.) We learned our skills relatively late in life. But imagine if we had learned as children and if, as adults, we tracked as if our lives depended on it? What additional visual and cognitive talents would we bring to our field work as scientists?

    Our mission is to find and document the fossilised tracks and traces of creatures that existed during part of the Pleistocene Epoch, between 35,000 and 400,000 years ago, on the Cape coast of South Africa. Since 2008, through the Cape South Coast Ichnology project, based in the African Centre for Coastal Palaeoscience at Nelson Mandela University, more than 370 vertebrate tracksites have been identified. They have substantially complemented the traditional record of body fossils. Examples include trackways of giant tortoises and giraffe.

    Given the challenges inherent in identifying such tracks, we wondered how hunters who’ve been tracking all their lives would view our work, and how age-old indigenous expertise might align with our approach.

    Fortunately we could call on experts with these skills in southern Africa. The Ju/’hoansi (pronounced “Juun-kwasi”) San people of north-eastern Namibia are perhaps the last of southern Africa’s indigenous inhabitants who retain the full suite of their ancient environmental skills. The Nyae Nyae conservancy in which they live gives them access to at least some of their historical land with its remaining wildlife. They still engage in subsistence hunting with bow and poisoned arrow and gather food that’s growing wild.

    A handful among them have been recognised as Indigenous Master Tracker, a title created by Liebenberg’s CyberTracker initiative in recognition of their top-flight hunter-gatherer status. And so, late in 2023, the Master Trackers #oma (“Komma”) Daqm and /uce (“Tchu-shey”) Nǂamce arrived in Cape Town.

    We were not the first to think along these lines. Ju/’hoansi Master Trackers have assisted scientists in the interpretation of hominin tracksites in French caves, and prehistoric tracks in the rock art record in Namibia. However, we knew that our often poorly preserved tracksites in aeolianites (cemented dunes) might present a stiffer challenge.

    Our purpose was to compare our own interpretations of fossil trackways with those of the Master Trackers, and possibly find some we had overlooked. As we’ve set out in a recently published paper with the Ju/’hoansi trackers and our colleague Jan De Vynck as co-authors, they did exactly this, confirming the first fossil hyena trackway ever to be found.

    Swapping techniques

    The Late Pleistocene is not that far distant from the present (a mere 125,000 years), and many of the species that made tracks on the Cape south coast then are still with us. Some are extinct but have recognisable tracks, like the giant long-horned buffalo and giant Cape zebra.

    We knew, though, that tracking in Kalahari sand, like the Ju/’hoansi do, is not the same as tracking on Pleistocene rock surfaces. Many of our tracks are preserved on the undersides of ceilings and overhangs, or are evident in profile in cliff exposures. Our track-bearing surfaces are usually small, and present no associated signs. We can’t follow the spoor for any distance. We don’t know at what time of day the tracks were made or the role of dew, and we have never succeeded in actually tracking down our quarry. Coprolites – fossilised droppings – are seldom found conveniently beside the tracks of the depositor.

    We showed our new colleagues known fossil tracksites, without providing our own interpretations. #oma and /uce discussed these between themselves and presented their conclusions about what had made the tracks and how the animal had been behaving. We then shared our insights and our 3D photogrammetry data where applicable, and reached joint conclusions.

    Soon they were identifying freshly exposed tracksites without our input, and were providing fascinating, new interpretations for sites which had puzzled us. For example, they saw ostrich tracks which we had missed, beside ostrich egg remnants, and concluded that we were probably looking at a fossilised ostrich nest. On another occasion they pointed out the distinctive track pattern of a scrub hare on the hanging wall of an eroded piece of cliff.

    First fossilised hyena trackway

    One of the most memorable experiences involved a 400,000-year-old trackway on a rock surface at Dana Bay, identified a few years earlier by local geologists Aleck and Ilona Birch. This rock had only been transiently exposed for a few days in the past decade, usually being covered by beach sand.

    Our earlier interpretation had been that the trackmaker might have been a hyena, probably the brown hyena.

    We were vindicated when our master tracker colleagues independently reached the identical conclusion. Examining our digital 3D images together fortified our collective judgement.

    This was a big deal: it was the first fossil hyena trackway to be confidently identified, as previous examples had involved only individual tracks or poorly preserved possible trackway segments. Hyena trackways are distinctive: the forefoot tracks are substantially larger than those of the hindfoot.

    Different ways of seeing

    Both of us are privileged to have university degrees and institutional affiliations. But there is another way in which acumen can be measured: the ability to use the ancient methods of discernment and pattern recognition to support and feed one’s family and community through tracking, hunting and gathering.

    What we have demonstrated, we believe, is a novel confluence of old and new ways to reveal fascinating features of the past. We use geological understanding, satellite technology, paleontological databases, tracking manuals and sophisticated dating methods. But hunter-gatherers see what escapes us and our drones: obscure strokes and enigmatic configurations on time-beaten surfaces. They tap an alternative knowledge base, both culturally received and cultivated from childhood.

    The follow-through challenge must be to develop this partnership for mutual discovery and reward, understanding the past to better equip us for our uncertain future.

  • MIL-OSI Submissions: Why your holiday flight is still not being powered by sustainable aviation fuel

    Source: The Conversation – UK – By Salman Ahmad, Lecturer in Operations and Supply Chain Management, University of the West of Scotland

    As you wait in the departure lounge for your flight this summer, you may notice your aeroplane being pumped full of fuel ahead of takeoff. And then you may start to wonder why flying is still so dependent on fossil fuels, and whether you should have booked a holiday destination that’s accessible by a more environmentally friendly form of transport.

    So what happened to plans for so-called sustainable aviation fuel? Wasn’t it supposed to be the “game changer” that would make flying a much greener travel option than it used to be?

    Clearly, the move to adopt the technology is facing difficulties. One problem seems to be that there simply isn’t enough sustainable fuel to go around.

    But the business side of the process is also holding back sustainable fuel uptake.

    Research my colleagues and I conducted in 2021 revealed a deeply fragmented landscape at pretty much every step of sustainable fuel development. There are obstacles everywhere, blocking the paths of the producers developing these fuels, the airlines who might use them and the governmental and campaign groups pushing for change.

    Everyone seems to agree that sustainable fuel matters. They just don’t all agree about how to really get it off the ground.

    Our findings demonstrate that producers, for instance, were understandably focused on more research and development to improve efficient production. They were also worried that scaling up facilities could disrupt production that is already in place.

    Airlines meanwhile, are grappling with the economics of moving to sustainable fuel, which is around three to ten times more expensive than conventional fuel. Right now, a litre of conventional aviation fuel costs around £0.96 per litre in the UK – for sustainable aviation fuel it’s around £1.97. (Depending on the length of the journey and the size of the engine, a plane could need around 13,000 litres per hour of flying.)

    They spoke about inconsistent supply (especially at major airports), and the need for clearer regulations and incentives across the industry.

    “Cost is clearly the most important driver,” one airline executive told us, explaining that dealing with those costs would ultimately depend on passenger demand for greener travel – and how willing those passengers are to pay a premium for sustainable fuel.

    Distribution companies that take the sustainable fuel where it needs to go, have found themselves struggling to navigate the complexities of an emerging supply chain. They spoke of the logistical challenges of transporting and storing sustainable fuel, and a lack of clear communication between producers and airlines.

    They saw themselves as a crucial part of the sustainable aviation fuel puzzle, but were concerned about investing in logistics and infrastructure without guaranteed demand.

    Elsewhere, politicians and climate campaigners tend to view the adoption of sustainable fuel from a broader perspective, stressing the urgency of action on climate change. Their thinking is dominated by environmental strategy and sustainable aviation fuel regulation.

    But here, trust becomes an issue. Some of those involved with sustainable fuel development said they doubted government promises to support the sector over the long term. Others are cynical about whether airlines will really prioritise climate action over their very tight profit margins.

    Up in the air

    So sustainable fuel inspires plenty of different viewpoints and concerns. But one common thread was an overwhelming concern about cost and scale of production.

    Aside from being far more expensive than fossil-based jet fuel, building enough production facilities to make more will require billions of pounds of investment.

    The big question is who will foot the bill.

    sustainable fuel, on a wing and a prayer?
    Bulent camci/Shutterstock

    Some of this will need to be tax funded. For if the UK wants to become a leader in the use of sustainable aviation fuel, as the government says it does, it needs more than ambitious targets. It needs to start making things happen.

    And our research suggests that the industry as a whole would benefit from some certainty to encourage investment right across the supply chain. Without a clear and stable regulatory framework, everyone will remain hesitant about committing significant resources to sustainable fuel.

    Collaboration between the key players could also be improved, with a better dialogue between those in the industry and regulators, potentially leading to a shared vision for the future of sustainable aviation fuel.

    That future is by no means doomed. Major commercial airlines like Air France-KLM, IAG (British Airways) and United Airlines in the US are working with sustainable fuel producers around the world.

    But while the desire to decarbonise aviation seems clear, the path forward is not straightforward. It is a complex picture of politics, economics, trust and differing priorities.

    By navigating this turbulence wisely, the sustainable fuel sector can be part of a broader flight path to net zero. But if managed poorly, targets to dramatically increase its use will remain elusive.

  • MIL-OSI Submissions: Discovery of a 4,000-year-old Bronze Age settlement in Morocco rewrites history

    Source: The Conversation – Africa (2) – By Hamza Benattia, Prehistory, Universitat de Barcelona

    A new archaeological discovery at Kach Kouch in Morocco challenges the long-held belief that the Maghreb (north-west Africa) was an empty land before the arrival of the Phoenicians from the Middle East in around 800 BCE. It reveals a much richer and more complex history than previously thought.

    Everything found at the site indicates that during the Bronze Age, more than 3,000 years ago, stable agricultural settlements already existed on the African coast of the Mediterranean.

    This was at the same time as societies such as the Mycenaean flourished in the eastern Mediterranean.

    Our discovery, led by a team of young researchers from Morocco’s National Institute of Archaeology, expands our knowledge of the recent prehistory of north Africa. It also redefines our understanding of the connections between the Maghreb and the rest of the Mediterranean in ancient times.

    How the discovery was made

    Kach Kouch was first identified in 1988 and first excavated in 1992. At the time, researchers believed the site had been inhabited between the 8th and 6th centuries BCE. This was based on the Phoenician pottery that was found.

    Nearly 30 years later, our team carried out two new excavation seasons in 2021 and 2022. Our investigations included cutting-edge technology such as drones, differential GPS (global positioning systems) and 3D models.

    A rigorous protocol was followed for collecting samples. This allowed us to detect fossilised remains of seeds and charcoal.

    Subsequently, a series of analyses allowed us to reconstruct the settlement’s economy and its natural environment in prehistoric times.

    What the remains revealed

    The excavations, along with radiocarbon dating, revealed that the settlement underwent three phases of occupation between 2200 and 600 BCE.

    The earliest documented remains (2200–2000 BCE) are scarce. They consist of three undecorated pottery sherds, a flint flake and a cow bone.

    The scarcity of materials and contexts could be due to erosion or a temporary occupation of the hill during this phase.

    In its second phase, after a period of abandonment, the Kach Kouch hill was permanently occupied from 1300 BCE. Its inhabitants, who probably numbered no more than a hundred, dedicated themselves to agriculture and animal husbandry.

    They lived in circular dwellings built from wattle and daub, a technique that combines wooden poles, reeds and mud. They dug silos into the rock to store agricultural products.

    Analysis shows that they cultivated wheat, barley and legumes, and raised cattle, sheep, goats and pigs.

    They also used grinding stones for cereal processing, flint tools, and decorated pottery. In addition, the oldest known bronze object in north Africa (excluding Egypt) has been documented. It is probably a scrap metal fragment removed after casting in a mould.

    Interactions with the Phoenicians

    Between the 8th and 7th centuries BCE, during the so-called Mauretanian period, the inhabitants of Kach Kouch maintained the same material culture, architecture and economy as in the previous phase. However, interactions with Phoenician communities that were starting to settle in nearby sites, such as Lixus, brought new cultural practices.

    For example, circular dwellings coexisted with square ones made of stone and wattle and daub, combining Phoenician and local construction techniques.

    Furthermore, new crops began to be cultivated, like grapes and olives. Among the new materials, wheel-made Phoenician ceramics, such as amphorae (storage jugs) and plates, and the use of iron objects stand out.

    Around 600 BCE, Kach Kouch was peacefully abandoned, perhaps due to social and economic changes. Its inhabitants likely moved to other nearby settlements.

    So who were the Bronze Age inhabitants?

    It’s unclear whether the Maghreb populations in the Bronze Age lived in tribes, as would later occur during the Mauretanian period. They were probably organised as families. Burials suggest there were no clear signs of hierarchy.

    They may have spoken a language similar to the Amazigh, the indigenous north African language, which did not become written until the introduction of the Phoenician alphabet. The cultural continuity documented at Kach Kouch suggests that these populations are the direct ancestors of the Mauretanian peoples of north-west Africa.

    Why this matters

    Kach Kouch is not only the first and oldest known Bronze Age settlement in the Maghreb but also reshapes our understanding of prehistory in this region.

    The new findings, along with other recent discoveries, demonstrate that north-west Africa has been connected to other regions of the Mediterranean, the Atlantic and the Sahara since prehistoric times.

    Our findings challenge traditional narratives, many of which were influenced by colonial views that portrayed the Maghreb as an empty and isolated land until it was “civilized” by foreign peoples.

    As a result, the Maghreb has long been absent from debates on the later prehistory of the Mediterranean. These new discoveries not only represent a breakthrough for archaeology, but also a call to reconsider dominant historical narratives. Kach Kouch offers the opportunity to rewrite north Africa’s history and give it the visibility it has always deserved.

    We believe this is a decisive moment for research that could forever change the way we understand not only the history of north Africa, but also its relationship with other areas of the Mediterranean.

  • MIL-OSI Submissions: New discoveries: three tiny species added to South Africa’s spectacular marine life

    Source: The Conversation – Africa – By Jannes Landschoff, Marine biologist at Sea Change and Research Associate at Stellenbosch University’s Department of Botany and Zoology., Stellenbosch University

    South Africa’s marine realm is globally unique because of the two major ocean currents that meet here. The cold, slow-moving Benguela and the warm, fast-flowing Agulhas currents create a special environment that supports high levels of biodiversity. Over 13,000 marine species are currently known to live in these waters. About 30% of these are endemic, meaning they occur nowhere else.

    Biodiversity metrics (the number or abundance of species) are dominated by invertebrates such as sponges, bivalves and crustaceans. These are usually small, which makes them adaptable and versatile. In terms of numbers, invertebrates make up a vast majority of marine life.

    I have been involved in marine biodiversity research for the last 10 years and have worked with teams of researchers, biology students and citizen scientists from across the country. I have also been involved in the naming and classification of organisms.

    In South Africa, where there is still much to discover, one focus of my work is identifying new species.

    Looking at subtle differences and finding similarities in how tiny organisms evolved in different regions is a global effort. In my own work, carried out together with many experts, there are three finds that have been particularly exciting – a “walking sponge” (Suberites ambulodomos), a tiny clam (Brachiomya ducentiunus) and a rare and miniature isopod (Pseudionella pumulaensis).

    Long-term efforts to identify new species like these guide effective conservation. They help to ensure that critical habitats are protected.

    These three newly described species may seem small and insignificant individually. However, small species make up the foundation of the food chain and play vital roles in nutrient cycling and in promoting biodiversity.

    The walking sponge

    First, there’s Suberites ambulodomos, or the “walking sponge”. This animal forms a unique partnership with hermit crabs. It settles on the tiny shell of a very young hermit crab. As the sponge grows it overgrows the shell completely, many hundred times in size and volume.

    As a result, the crab – which usually needs to search for a bigger shell as it grows – never outgrows its home. Instead, it carries the sponge with it.

    This is the first symbiotic relationship of its kind recorded in South African waters. This hermit-crab associated sponge was described in a collaborative effort by South African researchers at several institutes including the universities of the Western Cape, Johannesburg and Cape Town.

    The tiny clam

    Next is Brachiomya ducentiunus, a small clam that lives in the spaces between the spines of a heart urchin. The heart urchin burrows into shallow gravel and spends its life largely hidden, feeding on food fragments trapped in the sand.

    This tiny clam highlights the richness of life beyond what is easily visible to the human eye. It was discovered
    through the 1001 Seaforest Species project, a science and storytelling initiative in Cape Town by the Sea Change Project. It was described and named, meaning scientifically proven to be new, by local researchers from the universities of Stellenbosch and Cape Town, and experts from Santa Barbara Museum of Natural History and the University of Colorado Boulder.

    The rare and miniature isopod

    Finally, the third new species is Pseudionella pumulaensis. This is a parasitic isopod – a tiny crustacean.

    It was discovered in Pumula, KwaZulu-Natal, a region known for its high biodiversity. This isopod has a rather sinister survival strategy: it attaches to the gills of hermit crabs and feeds on their body fluids. Only two specimens have ever been found: a female measuring 2–3 millimetres and an even smaller male, so tiny it was almost missed entirely during the discovery process. I discovered it by chance during my PhD research on hermit crabs, while photographing and zooming in to the smallest details to carry out this work.

    Parasites tend to be small and hidden on, or inside, their hosts. They can be overlooked. However, they are vital to understanding biological processes as they regulate populations and are main drivers of evolution.

    Pseudionella pumulaensis is the first of its genus in the entire Indian Ocean, a testament to how much more marine life we have yet to uncover. With my local support the isopod was described by an international expert at Hofstra University, New York, and published through the Senckenberg Ocean Species Alliance, a collaborative global initiative to advance marine taxonomy.

    Biodiversity knowlege can help save our heritage

    The majority of species on Earth remain unidentified. Over 242,000 marine species have been described globally, but the actual number of living ocean species may exceed one million. Many species remain undiscovered, and a large proportion of those already identified are poorly understood. We’re now racing against extinction to learn about and from them before it’s too late.

    There is a lack of funding and job opportunities in discovering new species. In fact, the field of taxonomic expertise may now be as endangered as many of the ecosystems and species it seeks to document.

    There are no simple, fast-track solutions to the biodiversity crisis – the threat of species extinction combined with vast, unexplored diversity, and the lack of expertise and resources to address this at scale. However, biodiversity initiatives that work collaboratively locally and globally to share expertise offer hope.

    Discoveries like these three new species from South Africa emphasise the need for continued exploration. Each species described brings us one step closer to understanding our oceans’ rich biodiversity and finding new ways to protect it.

  • MIL-OSI Submissions: Post-flood recovery: lessons from Germany and Nigeria on how to help people cope with loss and build resilience

    Extreme climate events — floods, droughts and heatwaves — are not just becoming more frequent; they are also more severe.

    It’s important to understand how communities can recover from these events in ways that also build resilience to future events.

    In a recent study, we analysed how communities affected by the extreme flood events of 2021 in Germany’s Ahr Valley and in Lagos, Nigeria, grappled with recovery from floods.

    Our aim was to identify the factors – and combinations of factors – that served as barriers (or enablers) to recovery from disasters.

    We found that financial limitations, political interests and administrative hurdles led to prioritising immediate relief and reconstruction over long-term sustainable recovery.

    In both cases immediate and long-term recovery efforts were siloed, underfunded and focused on reconstruction to pre-disaster conditions.

    We concluded from our findings that the success of recovery efforts lies in balancing short-term relief and a long-term vision. While immediate aid is essential after a disaster, true resilience hinges on proactive measures that address systemic challenges and empower communities to build a better future.

    Recovery should not be merely action-oriented and building back infrastructure (engineering). It should also include insights in other areas, like governance and psychology, helping people to deal with losses and to heal.

    What worked

    To understand the recovery pathways of the two regions, we reviewed relevant literature, newspaper articles and government documents. We also interviewed government agencies, NGO representatives, volunteers and local residents in the communities where these floods occurred.

    We found that in the Ahr Valley, recovery wasn’t just about rebuilding structures, it was about empowering individuals.

    Through initiatives like mental health and first aid courses, residents learned to support one another. This fostered a sense of community and resilience that was essential for meeting the emotional challenges posed by the disaster.

    The focus on rebuilding with a sustainable vision also included environmental initiatives. For example, a type of heating system was put in place that didn’t rely on fossil fuels.

    Not only did this reduce carbon emissions, it also served as a symbol of hope. It showed there was an opportunity to create a more sustainable and environmentally friendly community.

    In Lagos, too, residents found strength in community and innovation. Grassroots efforts using sustainable materials like bamboo and palm wood highlighted the ingenuity and resourcefulness of the people. Faith-based organisations provided material aid as well as emotional and spiritual support. This reinforced the bonds that held the community together.

    Each community faced unique challenges. But they shared a common thread: the importance of adaptive governance – flexible decision-making and strong community ties.

    For example, established building codes in the Ahr Valley provided a framework for reconstruction, ensuring that new structures were resilient and safe.

    In Lagos, the absence of strong government support highlighted the critical role of community organisations in providing services and fostering a sense of shared responsibility.

    What needs improvment

    In both the Ahr Valley and Lagos, the journey towards recovery has been fraught with obstacles as well.

    In the Ahr Valley, bureaucratic red tape has become a formidable barrier. Residents, eager to rebuild their lives, find themselves entangled in a complex web of regulations and lengthy approval processes. This has delayed their access to insurance and recovery funds. Waiting for months or even years has eroded hope and fuelled a sense of abandonment.

    Meanwhile, in Lagos, insufficient government support has left communities to fend for themselves, creating a breeding ground for uncertainty and conflict.

    Land tenure disputes, fuelled by a lack of clear property rights, sow seeds of distrust and hinder resettlement efforts. Political disagreements complicate the picture, as competing interests divert attention and resources away from those who need them most.

    In Lagos, none of the respondents reported having insurance to help them to recover from disaster-related losses.

    While some residents in the Ahr Valley did have insurance, many were under-insured.

    The Ahr Valley’s building codes offer a framework for reconstruction. But it’s clear that processes should be streamlined so communities can take ownership of their recovery.

    In Lagos, the importance of robust social safety nets is clear. Partnerships between communities and authorities are also needed.

    A different approach

    Recovery isn’t a separate process that occurs after disasters only. It should be seen as an essential part of managing risks. It’s important to understand what recovery involves and what resources are needed.

    This will help reduce future risks and increase resilience after extreme events.

    Governments should encourage flexible governance structures that value community voices and local knowledge to enable recovery. A good example is the New Orleans Recovery Authority, established after Hurricane Katrina. It involved local residents and city officials in planning and rebuilding efforts.

    Grassroots efforts in Lagos demonstrated the power of sustainable materials and community-led initiatives. Seeing things from the community’s point of view can help tailor solutions that fit the situation and adapt to evolving challenges.

    Training and capacity-building programmes empower communities to be active in their own recovery.

    Mental health and first aid courses were successful in the Ahr Valley. Equipping individuals with skills in sustainable practices and disaster preparedness helps weave a social fabric capable of weathering future storms.
