If something online promises to cure everything, it’s probably too good to be true. One of the most dangerous examples? Chlorine dioxide is often marketed under names like “Miracle Mineral Solution (MMS)” or “aerobic oxygen”, buzzwords that hint at health and vitality.
But in reality, these products can make you violently ill within hours – and in some cases, they can be fatal.
Despite what the name suggests, MMS is not just bleach. Bleach contains sodium hypochlorite, whereas MMS contains sodium chlorite – a different but equally toxic chemical.
When ingested, sodium chlorite can cause methemoglobinemia, a condition where red blood cells lose their ability to carry oxygen. It can also trigger haemolysis (the rupture of red blood cells), followed by kidney failureand death.

When sodium chlorite mixes with acid (such as stomach acid), it converts into chlorine dioxide, a bleaching agent. This compound has strong antimicrobial properties: it can kill bacteria, fungi and even viruses like SARS-CoV-2. For that reason, it’s commonly used in sanitising dental equipment and hospital tools like endoscopes. Its effectiveness at killing over 400 bacterial species makes it useful in cleaning – but not in humans.
While the mouth and oesophagus are lined with multiple cell layers, offering some protection, the stomach and intestines are far more vulnerable. These organs have a single-cell lining to absorb nutrients efficiently – but this also means they’re highly sensitive to damage.
Using MMS as an enema is equally dangerous. Chlorine dioxide can trigger an overproduction of reactive oxygen species – unstable molecules that damage cells and contribute to chronic gut conditions. This cellular stress may explain both the immediate symptoms and the long-term injuries seen in reported cases.
It doesn’t make a good mouthwash, either
Some sellers claim MMS can be used safely in the mouth because it’s found in dental cleaners. But clinical trials show it’s no more effective than other mouthwashes, and its oxidising power doesn’t distinguish between harmful microbes and healthy cells.
Chlorine dioxide doesn’t just attack the gut. It also affects the cardiovascular system. Documented risks include low blood pressure, fainting, and cardiac damage – including stroke and shock.
Chlorine dioxide is also a respiratory irritant. Inhalation can inflame the nose, throat and lungs, and in severe cases, cause respiratory distress – particularly with repeated exposure in workplaces.
Studies of factory workers show that even low doses can lead to nasal inflammation, coughing and breathing difficulties. And some patients who drank chlorine dioxide to “treat” COVID-19 ended up with severe chemical lung injuries.
It doesn’t stop there. Some people who consume chlorine dioxide also develop cerebral salt wasting syndrome, a condition where the kidneys lose too much sodium, leading to excessive urination, dehydration and dangerously low blood volume.
Skin contact isn’t safe either. Chlorine dioxide can irritate the skin, and lab studies show it can kill skin cells at high concentrations. People who’ve used it to treat fungal infections have ended up with chemical dermatitis instead.
Chlorine dioxide can be useful for disinfecting hospital tools, dental equipment and water supplies. But that doesn’t mean it belongs in your body. Many of its supposed “benefits” come from lab studies or animal research – not from safe, approved human trials.
There’s no evidence that drinking it cures any disease. There’s overwhelming evidence that it can harm or kill you.
So, if you’re tempted by a product that promises miracles with science-y language and zero regulation, take a step back. The risks are very real – and very dangerous.

Representatives from 175 countries will gather in Geneva, Switzerland, in August for the final round of negotiations on a legally binding UN treaty to end plastic pollution. Non-governmental organisations, academics and industry lobbyists will also be in the room. They will all be hoping to influence what could be the world’s first truly global agreement on plastics.
The summit, known as “INC-5.2”, follows a failed attempt to reach agreement in Busan, South Korea, late last year. That meeting ended without resolving important issues, despite hopes that it would conclude the treaty process. Now, it’s crunch time in Geneva.
Either countries bridge their political divides, or risk the whole process falling apart.
I’ve been researching the effects of plastic for more than a decade and have been involved in the UN treaty process since 2022. I’ve attended several of the negotiations and will be in Geneva next month. The science is clear: we need ambitious action which tackles every stage of the plastics lifecycle, from production through to disposal. But the question is, will countries deliver?

In 2022, the UN Environment Assembly agreed to develop a legally binding treaty to end plastic pollution. Since then, progress has been slow. Negotiations have repeatedly stalled over issues such as whether the treaty should limit plastic production or regulate chemicals, how to define terms, and how to fund implementation.
Industry lobbying has also played a powerful role throughout. At the last round of talks, lobbyists for the petrochemical and plastics industries made up the single largest delegation. They outnumbered representatives from the EU, all of Latin America, the Pacific islands, independent scientists and Indigenous communities. This imbalance threatens to weaken the science-based action that is urgently needed.
Although countries failed to reach agreement in Busan, a foundation was laid. They agreed to continue negotiations using the “chair’s text”, which is a draft treaty with multiple options still on the table. That document forms the starting point in Geneva. But it remains uncertain whether enough common ground can be found to finalise the text.
What’s at stake?
This treaty is a once-in-a-generation chance to tackle one of the world’s most urgent environmental crises. More than 450 million tonnes of plastic are produced every year. That figure is expected to double by 2045 if current trends continue.
Only around 9% of plastic is ever recycled. The rest is landfilled, incinerated or ends up polluting the environment.
An estimated 139 million tonnes of plastics pollute marine and fresh water. But that could be significantly higher when considering leakages of plastics to land, and from microplastics, which are plastics smaller than 5mm in diameter.
Plastic is found in the deepest oceans, the remotest mountains and inside the human body. While scientists are only beginning to understand the long-term implications for human health, biodiversity and climate, studies show harmful effects of plastics and their chemicals on animals and ecosystems.
Plastic pollution doesn’t respect national borders. It moves through rivers, oceans and air, and gets carried across continents. Global supply chains and waste exports have made this a problem no country can solve alone. That’s why a global treaty is essential.
Crossroads
Despite this growing urgency, a disparity in positions has hindered progress and continues to divide delegations.
Some, such as members of the High Ambition Coalition, a group of countries committed to progressive climate action, want strong rules to cap plastic production, phase out toxic chemicals and hold polluters accountable. Others, often with prominent petrochemical industries, argue for a weaker, voluntary approach focused mainly on recycling and waste management.
If these divisions aren’t resolved, there’s a real risk the treaty will end up being too watered down to make a difference. A patchy, fragmented agreement would fail to curb rising plastic production and could undermine the integrity of global action.
Between December’s meeting in Busan and next month’s talks, countries have been holding smaller meetings to try to find compromise. That momentum must now be carried into the final negotiations.
Important articles in the draft treaty, including those on chemicals and products, plastic production and finance, remain contested. Whether those provisions are strengthened or diluted will shape the treaty’s effects for decades to come.
Flexibility will be needed. But leadership is also crucial. Countries that support an ambitious outcome must stand firm and bring others with them.
As we approach what may be the final negotiating round, we’re at a critical crossroads. The world has the chance to take meaningful action on plastic pollution. Let’s not waste it.

But my research suggests that the country might not be so reliant on tourism in the future, as it looks to become a major player in global maritime trade. The island’s numerous harbours and enviable location along international sea routes have led to major investment from China and the US, as they seek to extend their strategic influence in the region.
Key to this has been improved logistics and port infrastructure. Business at the port of Colombo, the country’s largest, is booming, aided in part by global shipping disruptions, including the Red Sea crisis, which rerouted vessels through the Indian Ocean.
But international maritime ambitions can be a complex affair, and Sri Lanka needs to be wary of becoming just a well-positioned commodity for the world’s economic superpowers.
Balancing these interests is a delicate act. While foreign investment is crucial for infrastructure development, Sri Lanka needs to protect its sovereignty and ensure that port operations serve national, not just international, interests.
My research suggests that one way of building a resilient and diverse Sri Lankan economy would be to focus on its surrounding waters. Sri Lanka’s vast “exclusive economic zone”, an area of sea where it controls marine resources, holds massive untapped potential.
Blue economy
This potential lies in traditional sectors like fisheries and tourism, but also emerging industries such as marine biotechnology.
This growing field offers opportunities in things like bioengineering and marine-based pharmaceuticals. With other countries rapidly advancing in these sectors, Sri Lanka is well-positioned to follow suit and become a regional leader in the blue economy (economic activities associated with the sustainable use of ocean resources).
But there is still a complex web of geopolitical interests and economic pressures to navigate, as well as environmental challenges.
At the moment for example, the Sri Lankan government is making plans for the deep natural port at Trincomalee to become a major marine repair and refuelling centre between Dubai and Singapore. Other proposed projects include offshore wind farms and oil rig facilities.
The country also needs to compete with the likes of Malaysia, which is investing heavily in AI-driven port operations. To stay competitive, Sri Lanka must modernise infrastructure and streamline processes.
And despite the progress, challenges persist. Poverty in Sri Lanka has doubled since 2021, while youth unemployment remains high.
Sri Lanka faces rising maritime threats like piracy and illegal fishing, requiring stronger maritime surveillance. Simultaneously, port expansion risks damaging marine ecosystems. Green technologies and stricter environmental regulations are essential for long-term security and sustainability.
Sri Lanka’s strategic location and maritime heritage offer a foundation for economic renewal. With wise governance, sustainability, and balanced geopolitics, its ports could once again become vital gateways to regional prosperity and global trade.

Throughout history, people have viewed seasons as relatively stable, recurrent blocks of time that neatly align farming, cultural celebrations and routines with nature’s cycles. But the seasons as we know them are changing. Human activity is rapidly transforming the Earth, and once reliable seasonal patterns are becoming unfamiliar.
In our recent study, we argue that new seasons are surfacing. These emergent seasons are entirely novel and anthropogenic (in other words, made by humans).
Examples include “haze seasons” in the northern and equatorial nations of south-east Asia, when the sky is filled with smoke for several weeks. This is caused by widespread burning of vegetation to clear forests and make way for agriculture during particularly dry times of year.
Or there is the annual “trash season”, during which tidal patterns bring plastic to the shores of Bali, Indonesia, between November and March.

At the same time, some seasons are disappearing altogether, with profound consequences for ecosystems and cultures. These extinct seasons can encompass drastically altered or terminated migratory animal behaviour, such as the decline of seabird breeding seasons in northern England.
Climate change is also calling time on traditional winter sport seasons by making snow scarcer in alpine regions.
Nature’s new rhythms
Perhaps more common are “syncopated seasons”. The changes are akin to new emphases on beats or off-beats in familiar music that capture the listener’s attention.
The timings of key seasonal events, like when leaves fall or certain migratory species arrive, are becoming more unpredictable. We coined the term “arrhythmic seasons”, a concept borrowed from cardiology, to refer to abnormal rhythms which include earlier springs or breeding seasons, longer summers or growing seasons, and shorter winters or hibernating seasons.
Changing seasonal patterns throw the interdependent life cycles of plants and animals out of sync with each other, and disrupt the communities that are economically, socially and culturally dependent on them.
In northern Thailand, human activity has reshaped nature’s rhythms and affected the supply of water and food in turn. Communities along the Mekong river’s tributaries have relied on the seasonal flow of rivers to fish and farm for generations.
At first, upstream dams disrupted these cycles by blocking fish migration and preventing the accumulation of sediment that farms need for soil. More recently, climate change has shifted rainfall patterns and made dry seasons longer and rainy seasons shorter but more intense, bringing fires and further uncertainty to farmers.
Let’s rethink time
How we react to changing seasonal patterns can either worsen or improve environmental conditions. In south-east Asia, public awareness of the “haze season” has led to better forecasting, the installation of air filters in homes and the establishment of public health initiatives.
These efforts help communities adapt. But if society only uses adaptive fixes like these, it can make the haze worse over time by failing to tackle its root causes. By recognising this new season, societies might normalise the recurrence of haze and isolate anyone who demands the government and businesses deal with deforestation and burning.
Powerful institutions like these shape narratives about seasonal crises to minimise their responsibility and shift blame elsewhere. Understanding these dynamics is crucial to fostering accountability and ensuring fair responses.
The shifting seasons require us to rethink our relationship with time and the environment. Today, most of us think about time in terms of days, hours and minutes, which is a globalised standard used everywhere from smartphones to train timetables. But this way of keeping time forgets older and more local ways of understanding time – those that are shaped by natural rhythms, such as the arrival of the rainy season, or solar and lunar cycles, rooted in the lives and cultures of different communities.
Diverse perspectives, especially those from Indigenous knowledge systems, can enhance our ability to respond to environmental changes. Integrating alternative time-keeping methods into mainstream practices could foster fairer and more effective solutions to environmental problems.
Seasons are more than just divisions of time – they connect us with nature. Finding synchrony with changing seasonal rhythms is essential for building a sustainable future.

Nestled in the southern Mediterranean, off the south-east coast of Tunisia, lies the island of Djerba. With a rich cultural and religious history, it has been a crossroad of many civilisations, including the Phoenicians, Romans, Byzantines and Arabs, and is home to many unique architectural sites. These include the Sedouikech underground mosque, St Joseph’s Church and the El Ghriba Synagogue.
But, for many years, Djerba’s cultural heritage has been in danger. This is due to a combination of over-tourism, environmental change and human neglect.
By the 1990s to early 2000s, when Djerba was at the height of its popularity, the island was attracting between 1 million and 1.5 million visitors each year. It is one of Tunisia’s most popular tourist areas, with more hotels than any other destination in the country.
Tourism has resulted in excessive tourist traffic in Djerba, particularly during the summer. It has also contributed to other problems such as water stress and waste generation. According to figures from 2020, hotels alone generate between 35% and 40% of all the waste on the island.
But the development of tourism has, above all, altered Djerba’s cultural landscape. In some areas of the island, Djerba’s traditional housing – houmas, menzels and houchs – have given way to more modern tourist infrastructure.
This has accelerated since Tunisia’s 2011 revolution, when long-time dictator Zine El Abidine Ben Ali was ousted. Weak institutional oversight has led to vandalism, illegal construction on archaeological sites and unauthorised demolitions.
The development of tourism on Djerba has also eroded traditional ways of life. The island has experienced significant changes due to tourism, with the development of roads, ferries, an airport and the internet leading to a decline in traditional activity. Livelihoods like agriculture, fishing and artisanal crafts have declined and are often now showcased only in tourist areas.
Climate change has worsened Djerba’s problems. Rainfall patterns have changed across the island over recent decades, with models suggesting that annual precipitation rates could drop 20% by the end of the century. More frequent and prolonged droughts are expected.
At the same time, rising sea levels and increasingly common storm surges are affecting the island. Research from 2022 found that 14% of Djerba’s beaches are now highly vulnerable to submersion and coastal erosion.
Several historical monuments on Djerba have already experienced periodic flooding and saltwater intrusion. The ruins of Sidi Garous and the shrine of Sidi Bakour are now entirely underwater and have been replaced by memorials.
Other archaeological sites located near the coast like Haribus, Meninx, Ghizene and Edzira, some of which date back to the Roman era (eighth century BC to fifth century AD), are now partially or fully submerged. Studies by Tunisia’s National Institute of Heritage suggest that many of these sites have been lost permanently to the encroaching sea.
World heritage site
Significant portions of Djerba’s cultural heritage have already been erased by sea-level rise and coastal erosion. Future losses could be even more severe. The island’s cultural heritage will only grow more precarious without meaningful preservation and climate adaptation efforts.
However, many of Djerba’s monuments, historical buildings and traditional dwellings have suffered from years of neglect. A chronic lack of local and international funding, as well as weak institutional frameworks for heritage management, mean some of the island’s historic structures have been abandoned. Many other buildings have deteriorated due to a lack of protective measures and maintenance.
Community organisations such as the Association for the Safeguarding of the Island of Djerba have tried to step in to fill the void left by weak institutional frameworks. Their work ranges from delivering public awareness campaigns to local young people to efforts like re-purposing ancient rainwater tanks to manage periods of drought.
But these grassroots efforts alone are not enough to stop Djerba’s cultural heritage from deteriorating at its current pace.

In September 2023, the UN Educational, Scientific and Cultural Organization (Unesco) announced that it was adding Djerba to its list of world heritage sites. Tunisia’s culture ministry welcomed the decision. It followed years of efforts by local groups and government officials to add Djerba to the list.
Djerba’s inclusion offers hope for the long-term preservation of the island’s heritage. A world heritage site designation increases global recognition and enables improved access to sources of funding.
And since Djerba’s classification, there has been some progress. The culture ministry has established a task force to monitor the construction of buildings and other infrastructure, collect data on designated protected areas, and prepare projects to preserve heritage sites.
But Djerba’s cultural heritage remains in danger. Improved preservation of these sites will require continuous funding and stringent regulation of tourism and construction activities.

With hosepipe bans in force across several English regions and more restrictions likely to follow, gardeners face some tough choices. When every drop counts, which plants deserve your precious water from the water butt, and which should you leave to fend for themselves?
As someone who has researched how British gardeners need to adapt to respond to our changing climate, I can tell you that not all garden plants are created equal when it comes to water needs. Some plants will bounce back from a summer scorching, while others may never recover.
Top plants to prioritise for watering
1. New woody plants
Any woody plant installed in the last 12-18 months should be your absolute priority. These haven’t yet developed the deep root systems needed to find moisture reserves and going without enough water the first year or so after planting could kill them.
Water thoroughly and add a deep mulch of wood chips to help the soil hold water. For young trees you can install a watering bag around the trunk but you still need to top it up.
2. Hydrangeas
Hydrangeas adopt a conservative strategy when it comes to drought. They shut their stomata (leaf pores) rapidly when they sense dry soil, and keep them closed until consistent moisture returns. They often drop their leaves too.
This can mean many weeks without growth, after even a relatively short drought period. So if you want to keep them looking at their best, they need consistent watering. You can cut growth back to reduce water loss, and save the the plant at the cost of flowers.
Japanese maples (Acer palmatum), along with other moisture-loving trees like birch and beech, are prone to serious die-back during summer droughts. Their shallow root systems and large leaves make them particularly vulnerable to water stress. Water and mulch them.
4. Soft herbaceous plants
Astilbe, dicentra, filipendula, heuchera, primula, trollius and many other soft herbaceous plants require good moisture levels and may not survive prolonged drought.
5. Shallow-rooted shrubs
Rhododendrons and azaleas are shallow-rooted shrubs particularly susceptible to drought stress, especially the large-leaved evergreen species which are also prone to wind damage when stressed.
6. Clematis
Many clematis varieties struggle with drought. Since they’re often grown for their spectacular flowering displays, maintaining adequate moisture around the roots is crucial, especially for autumn-flowering varieties, or spring-flowering varieties which flower on the previous year’s growth.
A gravel mulch can help keep the roots cool and damp. However, clematis orientalis, terniflora, and evergreens such as C. cirrhosa can be surprisingly tolerant of a hot dry period.
7. Ripening vegetables
If you’re growing vegetables, prioritise crops approaching harvest and those that split when moisture returns after drought, such as carrots. Runner beans and courgettes need moist soil to keep cropping and potato yields are heavily influenced by water levels.
8. All the pots
Anything in pots has limited access to soil moisture reserves and will need regular attention. Move containers to shadier spots if possible. Always use a pot saucer to hold water and prevent it draining away.
Plants that can survive without extra water
Research into plant water-stress shows that many common garden plants are surprisingly resilient.
Forsythia adopts a risk-taking strategy. It keeps growing and photosynthesising even when soil moisture becomes limited, gambling that it can regrow after damage. This makes it remarkably drought-tolerant. It is also tolerant of heavy pruning which can save it in severe conditions.
Mediterranean shrubs like lavender, rosemary, sage and thyme are naturally adapted to dry conditions. Their grey, hairy or waxy leaves are evolved to conserve moisture. Soil conditions are crucial though. If the plants are deep rooted they will draw water up, but if your soil is shallow or compacted they might well be less drought tolerant.
Sedums, sempervivums and other succulents store water in their fleshy leaves and can survive extended dry periods. RHS research identifies Sedum spectabile as particularly reliable under stress.
Buddleja can cope better than you might think in dry spells. Steidi/Shutterstock
Ornamental grasses generally have efficient root systems and many species actually prefer drier conditions once established.
Established shrubs including cistus, phlomis, buddleja, cotoneaster, berberis and viburnum have deep roots and proven track records for drought survival. The RHS report identifies these as garden stalwarts, with high stress resilience.
Grass lawns are thirsty and can be left to go dormant. If you have a newly seeded or turfed lawn from this year, some limited watering may be justified. But in general, embrace the golden colour of water-stressed lawns. As long as you don’t create too many bare patches from over-use, the green colour and growth will come back when it rains.
Annual bedding plants like busy lizzies and begonias have shallow root systems and high water demands. However, they are only there for one season and are easily replaceable, so prioritise them for watering only if they’re particularly important to your garden’s summer display and you can spare the water. You could save some by potting them up and enjoying a display that needs less water.
When you do water, research shows that technique is crucial. Water thoroughly but less frequently to encourage deep root growth. Focus water at the base of plants rather than on leaves, and water in early morning or evening to reduce evaporation.
Consider “split-root” watering for established shrubs – water one side of the plant thoroughly, then switch to the other side two to three weeks later. This keeps plants hydrated while chemical signals from the dry side’s roots prevent excessive new growth that would increase water demands.
This drought is a taste of Britain’s gardening future. The plants struggling most in this year’s drought are likely to become increasingly unsuitable for British gardens without intensive irrigation.
Be willing to swap out plants that suffer in drought for new plants that are more tolerant. Refresh plantings to adapt to the new climate.

With a few exceptions, philosophers have had little to say about clothes. Maybe this is because the topic seems frivolous, or feminine, unworthy of the attention of a predominantly male collection of thinkers.
Perhaps, too, the transience of fashion, and the fact that clothes belong – quite literally – to the domain of mere appearance, also has something to do with it. In A Philosopher Looks at Clothes, an engaging and informative book, Kate Moran, philosophy professor at Brandeis University in the US, urges us to think again.
As Moran points out, clothing looms large in life. Every day we dress, deciding how many layers to wear and whether we need a coat – or might a cardigan suffice? We gaze critically at other people’s choices (“OMG, those shoes!”). We wonder how to rise to the challenge of an imminent Eurovision-themed party.
From a historical point of view, also, our species-specific recourse to clothes stretches back to the earliest human society. In mythical time, it begins with Adam’s and Eve’s discovery, in shame, that they were naked. If fashion is transient, clothes, per se, are not.

Clothes, Moran tells us, serve three basic purposes: protection, modesty and decoration. At once, these introduce questions of deep philosophical interest. Are the purposes equally important? Why, throughout human history, have we refused to settle merely for protection, desiring for example that a hat should be of some favoured colour or shape? To what extent do our decorative choices express our personal identity? Do clothes ever qualify as works of art? Why is modesty an abiding concern, given that we all know the contours of the unclothed body?
In many contexts, and especially today, clothes invite ethical and political assessment. Clothes communicate a great deal of information about us, including our social position and the causes we espouse.
We may knowingly exploit this, choosing to flaunt an obviously expensive garment or to wear our football team’s scarf. In other cases the meanings are imposed. The uniforms forced on prisoners, for example, emphasise subordination and erase their individuality.
Poignantly, research into textile history has uncovered a streak of resistance in even the most ill-treated captives. In concentration camps during the second world war some prisoners altered their uniforms, or mended them, or added pockets. As Moran remarks, these actions were not just practical; their aim, too, was to “recover some sense of identity and dignity”.
We need more books like these, to counteract the entrenched pretence of disinterestedness in philosophy. (Nietzsche, exceptionally, saw through it, denouncing philosophers as “advocates who do not want to be seen as such … sly spokesmen for prejudices that they christen as ‘truths’”.)
Knowledge of the significance, in an author’s life, of her subject-matter enriches the reader’s imaginative experience of a book. Describing herself as an “ardent hobbyist” who sews her own clothes, Moran provides an additional facet to her account of today’s fashion industry and its scandalous environmental costs.
The reader knows that Moran herself has found an alternative. This lends a certain authority to her judgement that, however futile it may seem for any one person to step off the fast-fashion bus: “There is an important moral difference between being inefficacious and being innocent.”
Moran shows how many areas of philosophy can illuminate the phenomenon of clothes: not only ethics and political thought, but also aesthetics, theories of communication, of personal identity, of gender and cultural appropriation.
For readers unfamiliar with academic philosophy, these forays offer a path into a rich conceptual landscape. Along the way, we are offered a multitude of riveting facts. Who would have guessed that pink has not always been for girls, and blue for boys? And there are pictures, too. My highlight was the “revenge dress” that Princess Diana wore to a gala dinner in the midst of hostilities with Charles, in a successful bid to divert press attention from his appearance on TV.

As plans for missions to Mars accelerate, so do questions about how the human body might cope. A return trip to the red planet would give more than enough time for someone to become pregnant and even give birth. But could a pregnancy be conceived and carried safely in space? And what would happen to a baby born far from Earth?
Most of us rarely consider the risks we survived before birth. For instance, about two thirds of human embryos do not live long enough to be born, with most losses happening in the first few weeks after fertilisation; often before a person even knows they’re pregnant. These early, unnoticed losses usually happen when an embryo either fails to develop properly or to implant successfully in the wall of the womb.
Pregnancy can be understood as a chain of biological milestones. Each one must happen in the right order and each has a certain chance of success. On Earth, these odds can be estimated using clinical research and biological models. My latest research explores how these same stages might be affected by the extreme conditions of interplanetary space.

Microgravity, the near-weightlessness experienced during spaceflight, would make conception more physically awkward but probably wouldn’t interfere much with staying pregnant once the embryo has implanted.
However, giving birth, and looking after a newborn, would be far more difficult in zero gravity. After all, in space, nothing stays still. Fluids float. So do people. That makes delivering a baby and caring for one a much messier and more complicated process than on Earth, where gravity helps with everything from positioning to feeding.
At the same time, the developing foetus already grows in something like microgravity. It floats in neutrally buoyant amniotic fluid inside the womb, cushioned and suspended. In fact, astronauts train for spacewalks in water tanks designed to mimic weightlessness. In that sense, the womb is already a microgravity simulator.
But gravity is only part of the picture.
Radiation
Outside Earth’s protective layers, there’s a more dangerous threat: cosmic rays. These are high-energy particles – “stripped-down” or “bare” atomic nuclei – that race through space at nearly the speed of light. They’re atoms that have lost all their electrons, leaving just the dense core of protons and neutrons. When these bare nuclei collide with the human body, they can cause serious cellular damage.
Here on Earth, we’re protected from most cosmic radiation by the planet’s thick atmosphere and, depending on the time of day, tens of thousands to millions of miles of coverage from the Earth’s magnetic field. In space, that shielding disappears.
When a cosmic ray passes through the human body, it may strike an atom, strip its electrons, and smash into its nucleus, knocking out protons and neutrons and leaving behind a different element or isotope. This can cause extremely localised damage – meaning that individual cells, or parts of cells, are destroyed while the rest of the body might remain unaffected. Sometimes the ray passes right through without hitting anything. But if it hits DNA, it can cause mutations that increase the risk of cancer.
Even when cells survive, radiation can trigger inflammatory responses. That means the immune system overreacts, releasing chemicals that can damage healthy tissue and disrupt organ function.
In the first few weeks of pregnancy, embryonic cells are rapidly dividing, moving, and forming early tissues and structures. For development to continue, the embryo must stay viable throughout this delicate process. The first month after fertilisation is the most vulnerable time.
A single hit from a high-energy cosmic ray at this stage could be lethal to the embryo. However, the embryo is very small – and cosmic rays, while dangerous, are relatively rare. So a direct hit is unlikely. If it did happen, it would probably result in an unnoticed miscarriage.
Pregnancy risks
As pregnancy progresses, the risks shift. Once the placental circulation – the blood flow system that connects mother and foetus – is fully formed by the end of the first trimester, the foetus and uterus grow rapidly.
That growth presents a larger target. A cosmic ray is now more likely to hit the uterine muscle, which could trigger contractions and potentially cause premature labour. And although neonatal intensive care has improved dramatically, the earlier a baby is born, the higher the risk of complications, particularly in space.
On Earth, pregnancy and childbirth already carry risks. In space, those risks are magnified – but not necessarily prohibitive.
But development doesn’t stop at birth. A baby born in space would continue growing in microgravity, which could interfere with postural reflexes and coordination. These are the instincts that help a baby learn to lift its head, sit up, crawl, and eventually walk: all movements that rely on gravity. Without that sense of “up” and “down,” these abilities might develop in very different ways.
And the radiation risk doesn’t go away. A baby’s brain continues to grow after birth, and prolonged exposure to cosmic rays could cause permanent damage – potentially affecting cognition, memory, behaviour and long-term health.
So, could a baby be born in space?
In theory, yes. But until we can protect embryos from radiation, prevent premature birth, and ensure babies can grow safely in microgravity, space pregnancy remains a high-risk experiment – one we’re not yet ready to try.

The last year has highlighted a political divide between young men and women. Data from elections in several countries shows that women aged 18-29 are becoming significantly more liberal, while young men are leaning more conservative. And a recent 30-country study found generation Z more divided than other generations on key questions around gender equality.
At the same time, there is growing evidence that this cohort is turning away from traditional dating and long-term romantic relationships. According to the National Survey of Family Growth, in the US between 2022 and 2023, 24% of men and 13% of women aged 22-34 reported no sexual activity in the past year.
This is a significant increase on previous years. And American teens are less likely to have romantic relationships than teenagers of previous generations.
In the UK, surveys over the past decades reveal a trend in reduced sexual activity, in terms of both frequency and number of partners, among young people. Dating apps are also losing their lustre, with the top platforms seeing significant user declines among heterosexual gen Z users in the last year.
Is the gendered political divide making dating harder? As sociologists of intimacy, our work has shown how relationships are affected by larger social, economic and political trends.
Our research on enduring gender inequality has shown that it can affect the perceived quality of intimate relationships and relationship stability. For example, heterosexual relationships are often underpinned by unequal divisions of emotional and domestic labour, even among partners with similar incomes.
Dating today can feel like a mix of endless swipes, red flags and shifting expectations. From decoding mixed signals to balancing independence with intimacy, relationships in your 20s and 30s come with unique challenges. Love IRL is the latest series from Quarter Life that explores it all.
These research-backed articles break down the complexities of modern love to help you build meaningful connections, no matter your relationship status.
Some commentators and researchers have identified a trend of “heteropessimism” — a disillusionment with heterosexual relationships, often marked by irony, detachment or frustration. Anecdotally, women have widely expressed weariness with the gender inequality that can emerge in relationships with men.
But heteropessimism has been identified among men too, and research has found that women are, on average, happier being single than men.
Take domestic labour. Despite progress towards gender equality in many areas, data shows that women in mixed sex relationships still shoulder the majority of housework and care. In the UK, women carry out an average of 60% more unpaid work than men. This gap persists even among couples who both work full-time.
In Korea, persistent gender inequality is thought to be behind the 4B movement. Young Korean women, fed up with sexist stereotypes which tie women to traditional roles, have declared their rejection of marriage, childbirth, dating and sex with men.
Beyond Korea, young women have declared themselves “boy sober”. Harassment, abuse and “toxic behaviour” on dating apps has reportedly driven young women away from wanting to date at all.
Others have embraced voluntary celibacy. One reason is that, for some women, the erosion of reproductive rights, such as the overturning of Roe v Wade in the US, sharpens the political stakes of intimacy. Political disagreements that may once have been surmountable in a relationship are now deeply personal, affecting womens’ bodily autonomy and experiences of misogyny.
Of course, gender inequality does not just negatively affect women. In education, evidence suggests boys are falling behind girls at every level in the UK, though recent research shows this has reversed in maths and science. Men report feeling locked out of opportunities to care for their children through old-fashioned parental leave norms, which offer minimal opportunities for fathers to spend time with their children.
Some influencers capitalise on real and perceived losses for men, pushing regressive and sexist views of women and relationships into the social media feeds of millions of boys and young men.
Given all of the above, it is not entirely surprising that young men are more likely than young women to report that feminism has done more harm than good.
Anxiety and uncertainty
But there are wider political and economic issues that affect both young men and women, and how (or whether) they date each other. Gen Z are coming of age in a time of economic depression. Research shows that those experiencing financial stress have difficulties in establishing and maintaining intimate relationships.
This may partly be because early stages of romance are strongly associated with consumerism – dinner out, gifts and so on. But there is also a lack of mental space for dating when people are under pressure to make ends meet. Insecure finances also affect young people’s ability to afford their own homes and have access to private spaces with a partner.
There are, additionally, growing rates of mental ill health reported by young people worldwide. Anxieties abound around the pandemic, economic recession, the climate and international conflict.
These anxieties play out in the dating scene, with some feeling that entering into a romantic relationship is another risk to be avoided. Research with UK-based heterosexual dating app users aged 18-25 found that they often saw dating as a psychological stand-off – where expressing care too soon could result in humiliation or rejection.
The result was that neither young men nor women felt safe expressing genuine interest. This left people stuck in the much-lamented “talking stage”, where relationships fail to progress.
As sociologist Lisa Wade and others have shown, even when casual sex is part of the picture, emotional attachment is often actively resisted. The proliferation of “hook-up culture” – characterised by casual sexual encounters that prioritise physical pleasure over emotional intimacy – may partly be a response to a cultural discomfort with vulnerability.
Gen Z’s turn away from dating doesn’t necessarily reflect a lack of desire for connection, but perhaps a heightened sense of vulnerability related to larger trends in mental ill-health and social, economic and political insecurity.
It may not be that young people are rejecting relationships. Rather, they may be struggling to find emotionally safe (and affordable) spaces where intimacy can develop.

Giant Mine, just north of Yellowknife, N.W.T., in September 2011. The gold mine officially opened in 1948 and was operational for over 50 years before it was closed in 2004.(John Sandlos)
Decades of gold mining at Giant Mine in Yellowknife, Northwest Territories, has left a toxic legacy: 237,000 tonnes of arsenic trioxide dust stored in underground chambers.
We document this history in our forthcoming book, The Price of Gold: Mining, Pollution, and Resistance in Yellowknife, exposing how colonialism, corporate greed and lax regulation led to widespread air and water pollution, particularly affecting Tatsǫ́t’ıné (Yellowknives Dene) communities.
We also highlight the struggle for pollution controls and public health led by Tatsǫ́t’ıné and their allies, including mine workers.
Sickness from Giant Mine
The story begins when prospectors discovered a rich gold ore body at Giant Mine in the 1930s. While mining started at the nearby Con Mine in the late 1930s, Giant’s development was interrupted by the Second World War. Only with new investment and the lifting of wartime labour restrictions in 1948 did Giant Mine start production.
Mining at Giant was a challenge. Much of the gold was locked within arsenopyrite formations, and to get at it, workers needed to crush, then roast the gold ore at very high temperatures.
Archival records show that federal public health officials recommended the roaster be shut down until arsenic emissions could be controlled. But the company and federal mining regulators dragged their feet, fearing the economic impact.
The result, in 1951, was the poisoning death of at least one Dene child on Latham Island (now Ndilǫ), near the mine; his family was compensated a paltry $750. Many Dene in Ndilǫ relied on snow melt for drinking water, and there were reports of widespread sickness in the community. Local animals, including dairy cattle and sled dogs, also became sick and died.
Only after this tragedy did the federal government force the company to implement pollution controls. The control system was not terribly effective at first, though as it improved, arsenic emissions dropped dramatically from nearly 12,000 pounds per day to around 115 pounds per day in 1959. Thousands of tonnes of arsenic captured through this process was collected and stored in mined-out chambers underground.
Fighting back against pollution
Throughout the 1960s, public health officials continually downplayed concerns about arsenic exposure in Yellowknife, whether via drinking water or on local vegetables.
By the 1970s, however, latent public health concerns over arsenic exposure in Yellowknife became a major national media story. It began with a CBC Radio As it Happens episode in 1975 that unearthed an unreleased government report documenting widespread, chronic arsenic exposure in the city. Facing accusations of a cover-up, the federal government dismissed health concerns even as it set up a local study group to investigate them.
They conducted hair samplings of Dene children and mine workers — the population most exposed to arsenic in the community — and submitted them for laboratory analysis.
The resulting report accused the federal government of suppressing health information and suggested children and workers were being poisoned. The controversy made national headlines yet again, prompting an independent inquiry by the Canadian Public Health Association.
The association’s 1978 report somewhat quelled public concern. But environmental and public health advocates in Yellowknife continued their fight for pollution reduction through the 1980s.
Giant’s toxic afterlife
As Giant Mine entered the turbulent final decade of its life, including a violent lockout in 1992, public concern mounted over the growing environmental liabilities. Most urgently, people living in and near Yellowknife began to realize that enough arsenic trioxide had been stored underground over the years to poison every human on the planet four times over.
Without constant pumping of groundwater out of the mine, the highly soluble arsenic could seep into local waterways, including Yellowknife Bay. When the company that owned the mine, Royal Oak Mines, went bankrupt in 1999, it left no clear plan for the remediation of this toxic material, and very little money to deal with it.
Public concern and activism by Yellowknives Dene First Nation and other Yellowknifers prompted a highly contested environmental assessment and the creation of an independent oversight body, the Giant Mine Oversight Board in 2015. Under the current remediation strategy, the toxic waste at Giant Mine will require perpetual care, imposing a financial and environmental burden on future generations.
Hopefully, the Canadian government’s appointment of the special representative means the colonial legacy of the mine will finally be addressed. Giant Mine serves as a warning about the current push from governments and industry to ram through development projects without environmental assessments or Indigenous consultations.
Extractive projects may generate short-term wealth, but they also compromise the national interest if they saddle the public with enormous costs and long-term consequences.

Antibiotic resistance is one of the biggest health threats we face today. It’s often blamed on the overuse of antibiotics, and for a good reason. But there’s another major factor quietly driving this crisis that doesn’t get as much attention: low vaccination rates.
In early 2025, Ontario had a measles outbreak with 2,200 cases as of mid-July, mostly in people who hadn’t been fully vaccinated. An outbreak in Alberta that began in March has expanded to more than 1,300 cases as of mid-July.
Measles had been eliminated in Canada since 1998, but it’s now reappearing, largely due to missed or delayed vaccinations. On the surface, these might seem like a limited viral outbreak. But the ripple effects go much further, causing more illness, more complications and, ultimately, more antibiotic use.
Why measles can lead to antibiotic use
Measles itself is a viral infection, so antibiotics don’t treat it directly. But the virus weakens the immune system, leaving people vulnerable to bacterial infections like pneumonia or ear infections, conditions that do require antibiotics.
Unsurprisingly, this pattern isn’t new. A 2019 study published in Pediatrics showed that many children hospitalized with measles in the United States developed secondary infections that required antibiotic treatment, especially pneumonia and ear infections.
While data from the Ontario outbreak is still being analyzed, experts expect a similar surge in antibiotic prescriptions to treat these preventable complications.
The antibiotic resistance chain reaction
Every time we use antibiotics, we give bacteria a chance to adapt. (NIAID), CC BY
Here’s where it gets dangerous. Every time we use antibiotics, we give bacteria a chance to adapt. The most vulnerable bacteria die, but tougher ones survive and spread. This leads to antibiotic resistance where treatments that used to work no longer do.
Even appropriate use of antibiotics, like treating a bacterial infection after measles, adds to the problem. And the more often we need to prescribe antibiotics, the faster this resistance builds.
A 2022 global study published in The Lancet estimated that antimicrobial resistance directly caused 1.27 million deaths in 2019 and contributed to many millions more. As resistance spreads, doctors are forced to use more toxic, expensive or last-resort drugs, and sometimes, no effective treatment exists at all.
Antibiotic resistance means that treatments that used to work no longer do. (NIAID), CC BY
How vaccines help fight resistance
Vaccines are one of the most powerful tools we have not just to prevent disease, but to reduce antibiotic use and slow resistance. By stopping infections before they happen, vaccines reduce the need for antibiotics in the first place.
Some vaccines protect directly against bacteria. Pneumococcal vaccines (PCV13, PCV15, PCV20) guard against a major cause of pneumonia, brain infections and ear infections. Haemophilus influenzae type b (Hib) and diphtheria vaccines prevent other respiratory bacterial diseases.
Other vaccines protect against viruses, which can weaken the body and open the door to bacterial infections called as secondary bacterial infections.
The MMR (measles-mumps-rubella) vaccine not only prevents measles but also reduces the chance of bacterial pneumonias that often occur after measles due to immunosuppression.
In fact, a 2020 study in Nature found that improving childhood vaccination coverage in low- and middle-income countries could reduce antibiotic-treated illnesses in kids under five by more than 20 per cent. That’s a massive step forward in the fight against antibiotic resistance.
A wake-up call
The measles outbreaks in Ontario and Alberta aren’t just local issues; they are a global warning. Each missed vaccine doesn’t just put one person at risk; it potentially means more infections, more complications and more antibiotics. That, in turn, means more antibiotic resistance for everyone.
Vaccines are not just about individual protection. They are a public health strategy that keeps antibiotics effective for when we really need them, especially for vulnerable people like cancer patients, transplant recipients and the elderly, who rely on antibiotics to survive routine infections.
Vaccines, in fact, do more than prevent disease. They protect our ability to treat infections by reducing the need for antibiotics and slowing the rise of resistant bacteria. With preventable diseases like measles making a comeback, now is the time to recognize the broader impact of vaccine hesitancy.
Choosing to vaccinate is more than a personal decision. It’s a way to protect our communities and preserve the life-saving power of antibiotics for generations to come.

It is reported that he was swimming at Playa Cocles in Limon province when a current pulled him offshore. This is a beach popular among surfers and one that’s known to have large waves and strong currents.
It’s also a beach that I have taken students to in order to study the formation of rip currents and to better understand what beach users know about the hazard.
What exactly are rip currents?
Rip currents — commonly referred to as rips or colloquially as rip tides — are found on ocean beaches and some large lakes around the world.
The rips at Playa Cocles and along a large part of the Costa Rican Caribbean coast are known as channel or bathymetric rips that form as the nearshore sand bar moves toward the land through the summer. The water thrown towards the land by the breaking waves returns offshore as a concentrated and fast flowing current at gaps in the nearshore sand bar.
During storm conditions, we have measured the rip currents at Playa Cocles at over two metres per second. These rips are known to increase rapidly (or pulse) in strength due to changes in wave breaking, leading to unsuspecting swimmers being taken far offshore and exiting beyond the zone of breaking waves.

While it can be difficult to spot a rip from shore, they can be identified by an area of relatively calm water between breaking waves, a patch of darker water or the offshore flow of water, sediment and debris.
Caught in a rip current
A person caught in a rip is transported away from shore into deeper waters, but they aren’t pulled under the water. If they are a weak swimmer or try to fight the current, they may panic and fail to find a way out of the rip and back to shore. Survivor stories highlight panic, anxiety, distress and fear, a tendency to fight the current and an inability to make a decision on how to escape the rip.
While it is possible to “break the grip of the rip” by swimming parallel to the beach or toward breaking waves at an angle to the beach, there is no single escape strategy due to the unique rip circulation pattern.
It’s possible to escape a rip by flipping onto your back, floating to keep your head above the water and following the current until you’re returned to the shore by the current or able to swim safely toward the shore. If you are taken beyond where the waves break, or you’re unable to swim back to shore, continue to float and signal for help.
Rip currents account for more than 50 deaths a year in Costa Rica; approximately 19 drownings a year involve foreign tourists from the United States, Nicaragua, Canada and Germany. While most drownings in the country occur on Pacific coast beaches that are a short distance to the city of San José, more than five drownings occur each year along the Caribbean coast.
On average, each drowning in Costa Rica costs more than US$2 million (USD). This includes the direct costs of search and rescue, the costs of repatriation and the long-term economic burden of a lost life. This is in addition to the great personal loss experienced by family and friends.
The majority of foreign drowning victims in Costa Rica had limited knowledge of rips and were unable to avoid the times and locations that were most hazardous.
In general, visitors to a beach often use simple visual cues when deciding to take risks. Recent studies suggest that tourists think beach access points and resorts are located adjacent to safe swimming areas, particularly when visual cues such as manicured paths and promotional posters that promote swimming at those locations.

Playa Cocles is a beautiful beach, but it’s known to have dangerous rips depending on the size of the breaking waves and the position of the sand bar.
When visiting any beach — from the Caribbean to the Great Lakes — it’s important to remember that there may be rip currents and to take serious precautions.
Ghana stands out in west Africa as a nation that has not experienced terrorist attacks, even though it’s geographically close to countries that have. In Burkina Faso, Mali and Nigeria, extremist groups such as Boko Haram and Islamic State in West Africa (ISWAP) have wreaked havoc.
This resilience is not accidental. It is the result of deliberate counter-terrorism strategies employed by Ghana’s security institutions.
Ghana’s counter-terrorism framework was set out in 2020. It has four pillars: prevent, pre-empt, protect, and respond. The idea is to coordinate multiple agencies, including the Ghana Police Service, Ghana Immigration Service, Ghana Armed Forces and the National Intelligence Bureau.
These pillars guide strategies to address both immediate threats and underlying vulnerabilities. Poverty, religious radicalism and porous borders are common drivers of terrorism in west Africa.
I am an international security and global governance researcher. My co-author is a government and international studies scholar.
We wanted to identify what works as a potential model for other countries.
Using a qualitative methodology, we interviewed stakeholders — including police officers, members of the armed forces, Muslim community leaders, and immigration officials. We also analysed the national framework for preventing and countering violent extremism and terrorism.
Our findings showed that Ghana’s success is traceable to an approach that integrates community engagement with advanced border technology, inter-agency training, media collaboration and intelligence operations. And it addresses both immediate and underlying threats.
We argue that Ghana’s ability to balance prevention with security offers solutions for stability in a geopolitically volatile region.
One of the standout strategies is community engagement. This serves multiple purposes, from guiding people away from extremism to gathering intelligence.
The Ghana Police Service, for instance, engages Muslim-dominated communities, known as “Zongos”, to counter radical Islamic ideologies that could be exploited by terrorist groups.
By collaborating with local religious leaders, police make communities aware of the dangers of radicalisation. They foster trust and encourage residents to report suspicious activities. This approach also works in tackling illegal arms circulation.
Ghana has an estimated 2.3 million small arms in circulation – 1.1 million of them illegally possessed. The availability of so many weapons fuels terrorist activities across west Africa.
Community based de-radicalisation aligns with global best practices. In Norway, for instance, it was used to disengage youth from extremist groups.
Technology at borders
Ghana’s border control management is another part of its counter-terrorism strategy. Ghana Immigration Service uses advanced security software and integrated systems like the “Immigration 360” system, designed to fully automate passenger processing and data management.
The system manages records of fingerprints and other data to improve reporting and intelligence sharing between Ghana Immigration and other security agencies.
The technology makes it possible to quickly identity individuals on terrorist watchlists and detects concealed goods. This helps prevent illegal cross-border movements.
There are gaps in Ghana’s defences, however. The influx of migrants fleeing extremist violence in Burkina Faso, Mali and Niger in 2024 highlights the urgency of scaling up investments in the technology.
Ghana combats new and varying forms of terrorism by uncovering trends and training personnel to deal with them.
A notable example was the six-day joint training in 2022 involving the Ghana Immigration Service, Police Service, Customs, Economic and Organised Crime Office, and the National Intelligence Bureau.
The country also works with regional neighbours like Burkina Faso, Togo and Benin, and partners such as the United States, through initiatives like “Operation Epic Guardian”.
Media as a strategic partner
Terrorists rely on media to amplify fear and publicise their causes. Ghana’s security agencies counter this tactic by actively engaging media houses to report accurately.
The Ghana Armed Forces, for instance, works with media to debunk false reports, which can cause public panic and inadvertently aid terrorists.
The Ghana Police Service emphasises regular dialogue with media to ensure sensitive information is verified before publication, reducing the risk of tipping off suspects. However, media competition for viewers poses a challenge.
Surveillance and intelligence gathering
Surveillance and intelligence gathering is critical. Plainclothes armed forces and immigration personnel blend into communities to monitor potential threats. The approach has worked but is constrained by resources.
It can also risk human rights violations, such as wrongful profiling, and is less effective against multiple targets compared to technological solutions like facial recognition or CCTV.
Despite its successes, Ghana’s counter-terrorism framework faces challenges that could undermine its long-term efficacy:
logistical and financial constraints
the influx of migrants fleeing regional violence
a lack of harmonised security cultures within the regional body, Ecowas.
In all, Ghana’s strategies offer lessons for west Africa, where terrorism is a growing threat.
Its community engagement model could be followed in Nigeria, Burkina Faso, Mali and Niger to counter radicalisation and arms proliferation, provided it avoids religious stereotyping.

Protecting livestock in areas where large carnivores (like lions) live is increasingly important as human land use expands, wildlife habitat shrinks, and climatic changes reshape the ways in which humans and wildlife interact. Protecting the carnivores from livestock owners is important too. Intact carnivore populations support more resilient food webs and the ecosystem services they provide.
It’s not easy for people, livestock, and carnivores to live together without conflict, though. One of the best ways to reduce conflict is to protect livestock like cattle and sheep from being attacked by predators.
There are various methods to do this, like guarding livestock or erecting fences. That’s all very well for the livestock inside the fences, but do predators simply turn to the nearest unprotected livestock for their meal instead? Are the neighbours’ cattle, sheep, and goats at greater risk? This question hasn’t been explored much by researchers.
We’re a group of conservation practitioners and scientists who have studied the interactions of carnivores, livestock, and people in Tanzania and elsewhere for decades to try and find solutions to conflict problems.
Our study area is next to a national park which protects important populations of lion, leopard, hyena, African wild dog, and cheetah. The people who live here have traditionally kept their livestock overnight in enclosures made of acacia-thorn branches. More recently, some of them have built pens, or corrals, from tall chain link fencing. We knew from years working with communities and from previous research that these fortified corrals were effective at keeping livestock safe from predators.
Our next step was to find out whether this made other nearby livestock less safe.
The results were intriguing. We found that the new enclosures made predation less likely in the nearby traditional enclosures too.
This type of beneficial spillover effect had yet to be documented in other systems where interventions aim to protect livestock from large carnivores.
Our results show that in conservation, it’s important to look closely at complex local dynamics. The findings may help explain why there’s so much uncertainty about the effectiveness of various human–wildlife conflict mitigation strategies.
Beneficial spillover effects
People who keep livestock in east Africa have long had strategies to keep their animals safe from large carnivores. Sometimes acacia-thorn night enclosures (known locally as bomas), intensive herding practices, and guarding dogs work well.
Other times, and especially in communities within and adjacent to large, protected carnivore populations, traditional strategies fall short.
This is the case in Tanzania’s Ruaha-Rungwa Landscape. In our study area adjacent to Ruaha National Park, any pastoralist or agropastoralist (herding and crop farming) household has about a 30% chance of losing one or more animals to predation each year. This is a serious economic loss on top of important cultural and emotional costs.
Lion Landscapes, an organisation that some of us have been running for over a decade, works to support human-carnivore coexistence. Adjacent to Ruaha, we have been partnering with households to build 1.8-metre chain-link corrals. We subsidise them. Households contribute 25% of the cost and some of the labour for construction.
We analysed about 25,000 monthly reports of livestock predation in fenced and traditional enclosures, using statistical models. There were 846 predation events over nearly four years. Unexpectedly, while we did detect spillover effects, these appeared to be beneficial. Rather than displacing conflicts, fortified enclosures actually conferred protective effects on their traditional-enclosure neighbours.
For example, households within 50 metres (the minimum observed distance) of a fortified enclosure were half as likely to experience predation compared with distant households 2 kilometres away. And these beneficial effects increased with the number of fortified enclosures in a neighbourhood. Finally, the effects appeared to be durable over time.
The fortified enclosures were extremely effective. We showed that households could break even after paying for the fence in just a few years through avoided livestock losses. And we know that when domestic animals aren’t being killed, their owners are more tolerant of predators. We didn’t record carnivore killings in this study but it has happened fairly frequently in the area in the past.
In a few of the world’s human-wildlife conflict systems, where data exist to assess spillover effects, there is evidence that detrimental spillovers do occur. For instance, beehive deterrents may redirect elephants to nearby crop fields, or lethal removal of individual wolves may redirect the surviving pack to prey on adjacent ranches. Nevertheless, these are very under-studied interactions.
Livestock management and carnivore coexistence
In systems where humans, livestock, and wildlife overlap and sometimes come into conflict, management strategies too often focus on wildlife. Another option is to reduce whatever attracts wildlife. In the case of large carnivores, this means managing livestock.
Our results support this approach by demonstrating that management and protection of livestock is fundamental for reducing conflict, and can benefit not only livestock owners but landscape-level coexistence.
Conservationists and policy-makers need to encourage these practices that benefit people, carnivores, and livestock in shared landscapes.

Statistics professor Johan Ferreira was feeling overwhelmed by the amount of “screen time” involved in online learning in 2021. He imagined students must be feeling the same way, and wondered what he could do to inspire them and make his subject matter more appealing.
One of the topics in statistics is time series analysis: statistical methods to understand trend behaviour in data which is measured over time. There are lots of examples in daily life, from rainfall records to changes in commodity prices, import or exports, or temperature.
Ferreira asked his students to write a short, fictional “bedtime” story using “characters” from time series analysis. The results were collected into a book that is freely available. He tells us more about it.
Why use storytelling to learn about statistics?
I’m fortunate to be something of a creative myself, being a professional oboe player with the Johannesburg Philharmonic Orchestra. It’s a valuable outlet for self-expression. I reflected on what other activity could inspire creativity without compromising the essence of statistical thinking that was required in this particular course I was teaching.
I invited my third-year science and commerce students at the University of Pretoria to take part in a voluntary storytelling exercise, using key concepts in time series analysis as characters. Students got some guidelines but were free to be creative. My colleague and co-editor, Dr Seite Makgai, and I then read, commented on and edited the stories and put them together into an anthology.
Students gave their consent that their stories could be used for research purposes and might be published. Out of a class of over 200 students, over 30 contributions were received; 23 students permitted their work to be included in this volume.
We curated submissions into two sections (Part I: Fables and Fairy Tales and Part II: Fantasy and Sci-Fi) based on the general style and gist of the work.
The project aimed to develop a new teaching resource, inspire students to take ownership of their learning in a creative way, and support them through informal, project-based peer learning.
This collection is written by students, for students. They used personal and cultural contexts relevant to their background and environment to create content that has a solid background in their direct academic interests. And the stories are available without a paywall!
What are some of the characters and stories?
Student Lebogang Malebati wrote Stationaryville and the Two Brothers, a tale about AR(1) and AR(2). In statistics, AR refers to processes in which numerical values are based on past values. The brothers “were both born with special powers, powers that could make them stationary…” and could trick an evil wizard.
David Dodkins wrote Zt and the Shadow-spawn. In this story, Zt (common notation in time series analysis) has a magic amulet that reveals his character growth through a sequence of models and shows the hero’s victory in the face of adversity. He is a function of those that came before him (through an AR process).
Then there’s Nelis Daniels’ story about a shepherd plagued by a wolf called Arma (autoregressive moving average) which kept making sheep disappear.
And Dikelede Rose Motseleng’s modern fable about the love-hate relationship between AR(1) (“more of a linear guy” with a bad habit of predicting the future based on the past) and MA(1), “the type of girl who would always provide you with stationarity (stability).”
What was the impact of the project?
It was a deeply enriching experience for us to see how students see statistics in a context beyond that of the classroom, especially in cases where students reformulated their stories within their own cultural identities or niche interests.
Three particular main impacts stand out for us:
students have a new additional reference and learning resource for the course content
new students can refer to the experiences and contextualisation of this content of former students, leading to informal peer learning
students engage in a cognitive skill (higher-order and creative thinking) that is not frequently considered and included in this field and at this level.
In 2024, shortly after the book was published, we asked students in the time series analysis course of that year to read any one of four stories (related to concepts that were already covered in the course material at that point in time). We asked them to complete a short and informal survey to gauge their experience and insights regarding the potential of this book as a learning resource for them.
The 53 responses we got indicated that most students saw the book as a useful contribution to their learning experience in time series analysis.
One positive comment from a student was:
I will always remember that the Random Walk is indeed not stationary but White Noise is. I already knew it, but now I won’t forget it.
Will you build on this in future?
It is definitely valuable to consider similar projects in other branches of statistics, but also, in other disciplines entirely, to develop content by students, for students.
At this stage, we’re having the stories and book translated into languages beyond English. In large classes that are essential to data science (such as statistics and mathematics), many different home languages may be spoken. Students often have to learn in their second, third, or even fourth language. So, this project is proving valuable in making advanced statistical concepts tactile and “at home” via translations.
Our publisher recently let us know that the Setswana translation is complete, with the Sepedi and Afrikaans translations following soon. To our knowledge, it’ll be the first such project not only in the discipline of statistics, but in four of the official languages in South Africa.

Amyotrophic lateral sclerosis (ALS) is a devastating neurological disorder of unknown cause, in which motor nerve cells of the brain and spinal cord that transmit signals to muscles progressively degenerate. This weakens limbs and affects speech, swallowing and ultimately the ability to breathe, resulting in death, typically within just a few years.
Each year in Canada, approximately two people per 100,000 are diagnosed with ALS, amounting to about 1,000 cases based on the current population. In British Columbia, where we are located, the rate is estimated at just over three per 100,000 or roughly 190 new cases per year.
Rigorous ALS research is underway locally, nationally and internationally to slow — and ideally reverse — the relentless progression of this disease. Significant advances in understanding the genetic and environmental drivers of ALS are providing genuine hope that motor neuron diseases will one day be defeated.
As experts in neurology and ethics, we are committed to delivering the best available health care and information throughout B.C. and across Canada. Trust in science and informed hope are essential to achieving the best possible outcomes and the longest possible trajectories in enjoying life when facing the overwhelming odds of ALS.
A disturbing case
In June, CBC’s The National reported on the case of Geoff Sando, a person living with ALS who pursued an unproven intervention for his condition. Sando travelled to Moose Jaw, Sask., to seek treatment at a clinic that claims to provide a cure for ALS.
CBC’s The National reports on a Saskatchewan clinic claiming to offer ALS treatments.
The ALS Society of Saskatchewan and the provincial New Democrat Party allege the clinic attended by Sando and several other patients is a form of medical tourism — travelling elsewhere to seek treatment — that can prey on the most vulnerable in society: those whose quality of life is deteriorating, and whose futures are tragically cut short.
In the United States and Mexico, unfounded stem cell interventions for ALS have been advertised for years. But until recently, it had been unusual to find such offerings in Canada. Their emergence speaks to the need for Health Canada to revisit its guidance on both regulated health and unregulated wellness products, including all forms of treatments, medications and device-based approaches.
We understand the urgency and desire to pursue any thread of hope in the face of desperation, but claims of dramatic improvement or cures from ALS by unregulated clinics that seem too good to be true are likely just that.
Before investing in alternative treatments, we recommend that patients conduct their due diligence by consulting with their health-care team and their provincial ALS society for guidance. Ineffective interventions can jeopardize not only recipients, but also caregivers, especially when financial resources are drained.
Although riluzole and edaravone are only modestly effective, they remain the only widely approved pharmacological options for all forms of ALS. Tofersen is the first gene therapy recently approved to treat hereditary ALS caused by SOD1 gene abnormalities. Other treatments are being evaluated worldwide.
This marks only the beginning of such treatment approaches to not only hereditary ALS but also non-hereditary ALS, which makes up about 90 per cent of all cases.
For those affected by ALS and their families, ample resources are provided by various organizations, including ALS Canada and related provincial organizations, including the ALS Society of BC.
But in this time of geopolitical upheaval, vast incursions of disinformation and reversals of prior evidence-based human and health rights abroad means keeping up this level of trust — trust that leads to hope — will only become more challenging.
The disproportionate suffering and impact on people who are marginalized by serious health conditions will only grow if dubious treatment offerings become normalized in Canada.

Plans to cut health-related benefits in the UK continue to give the government political grief – as well as being a huge worry for claimants. Underpinning the controversy are government plans to move more people into work with a long-term ambition of 80% employment.
But cutting welfare costs is a blunt and unhelpful way to face the challenge of increasing employment among people with long-term health conditions.
For people with fluctuating and often invisible conditions such as multiple sclerosis (MS), welfare and work are not opposed. They are usually part of the same life journey – one that is rarely linear and requires systems and supports that are flexible, not punitive.
This was the focus of a recent study led by my research colleague Aman Navani and the MS Society. It is a major UK survey of people with MS with more than 1,100 respondents, and highlights systemic failures in workplace support and welfare systems.

Because of its fluctuating nature, MS can act as an important case study to understand how work should accommodate people’s evolving health needs. It also offers lessons that are relevant to a wide array of other conditions.
Women are more likely to have MS, which is usually diagnosed in people in their 30s or 40s. These, of course, are peak working years.
The vast majority of people with MS (96%) who participated in our study reported that their condition has affected their ability to work. This is because MS can make commuting and navigating workplace environments challenging, and physical and mental health impacts often overlap.
Managing symptoms such as cognitive changes, pain and restricted mobility can contribute to anxiety and depression. All of these things put additional strain on the working lives of those affected.
For a quarter of respondents (24%), MS had such a severe effect that they felt unable to work at all. Worryingly, one in two people said they have compromised their health by staying in a job.
For many, leaving work is the only solution they can see. More than one-quarter (26%) cited unmanageable workloads, 19% could not afford to stay in work due to low pay, 20% lacked flexible hours, and for 22% the flexibility they were offered did not meet their needs.
Just 8% said their employer helped them adapt their job to suit their health, and only 2% had progression opportunities tailored to their condition. But nearly half (45%) of those who left work said they could have stayed if their employer had understood their condition better.
Almost half (46%) of respondents who were in work had used the personal independence payment (Pip) as a lifeline. This is an allowance that helps people with the extra living costs associated with having a disability. Under the government’s plans, conditions will be tightened for new claimants.
Designing better jobs
Living with a fluctuating condition requires constant adaptation, from coping with exhaustion to managing the extra time and cost of daily activities. As such, the way jobs are designed matters.
A government report has said that one-quarter of those who are out of work and claiming health and disability benefits might be able to work if they could do so from home.
The rise of remote and hybrid work has indeed been a lifeline for some disabled workers. A recent major study of people who are classified as disabled highlights just how vital this change has been for them: 85% said remote or hybrid work was essential or very important when job hunting, and 79% wouldn’t apply for roles without it.
Among those working fully remotely, 64% said their physical health improved. Homeworking was valued by those with fluctuating conditions such as MS, and for disabled women and carers in particular, full-time homeworking was their preference.
But these gains are precarious. Growth in hybrid roles has stalled and some employers are grabbing headlines with “return-to-office” mandates even at the risk of losing key members of their workforce.

Nearly one in four working-age people in the UK are disabled. Work and welfare must be designed from the perspective of this growing and diverse cohort – ensuring financial security for people with health conditions, both in work and out of work.
Expanding and protecting access to secure and flexible jobs is key, including remote and hybrid roles, baking these models into more sectors of the economy. The government could lead by example with public sector workers, and protect jobs from knee-jerk employer mandates.
In January this year, only 3.8% of vacancies on the Department for Work and Pensions jobs portal included an option for hybrid or remote work.
This would enable people with fluctuating conditions to attend appointments, recuperate and even take career breaks without harming their careers. For this, the UK needs a benefits system that supports movement in and out of work, avoiding financial cliff edges.
Too many people with MS and similar conditions who can and want to work are forced to leave jobs early due to inadequate support. They face a trade-off between progressing their working life and managing their health. The challenge for government and employers now is to remove this tension.

Dog theft can be a devastating crime. During the COVID pandemic, newspapers suggested there was an epidemic of “dognapping” in the UK. If you have a dog, the reports may have alarmed you at a time when there were already many reasons to feel afraid.
There are mixed views on whether or not lockdown triggered an increase in dog ownership. Animal welfare charity Battersea attributed a 53% increase in dog adoption to lockdown, and online pet adoption service Pets4Homes said in their 2022 report that demand for puppies rose 104% at the peak of lockdown in May 2020.
But animal charity PDSA said its survey data pointed to a gradual increase in dog ownership since 2011 rather than a dramatic surge during lockdown. However, we do know lockdown saw inflated prices for dogs, with some fashionable breeds going for £9,000.
In terms of criminal activity, social distancing restrictions seemed to lead to a decline in some forms of crime, including shoplifting and burglary. But many media outlets reported the number of dog thefts had increased up to 250% during the pandemic.

We wanted to explore if the data supported claims of a dognapping epidemic and whether patterns in dog theft could suggest ways to help reduce it. Our recent study found new insights into dog theft patterns and showed the situation was more complicated than it seemed at first glance.
This means police records on dog theft were not included in crime statistics. The only way to access such information is through Freedom of Information (FOI) requests to individual police forces. There are 45 territorial and three special police forces in the UK, and each has its own reporting and recording practices.
Although police FOI data for dog theft must be approached with caution, it is useful. Previous studies exploring police FOI data found an upward trend in recorded dog thefts in England and Wales: rising nearly 20% from 2015 (1,545) to 2018 (1,849) for 41 police forces combined; and up 3.5% year on year from 2019 (1,452) to 2020 (1,504) for 33 police forces.
DogLost, a UK online community for reuniting lost and stolen dogs with their owners, reported a 170% increase in stolen dogs (with Crime Reference Numbers) registered on their website in 2020 (465), compared to 2019 (172). This figure was widely quoted as a national increase “since lockdown started” by the media.
The 250% increase figure first quoted in December 2020 was actually a comparison of two seven-month periods (January-July 2019 and 2020) for only one police force.
Patterns and trends
Our study found the data for the period covering the COVID pandemic is also incomplete. Data was provided by 32 forces (71%) for 2020, by 27 forces (60%) for 2021, and 23 forces (51%) for 2022.
Patterns and trends do, however, emerge. Between 2020 and 2022, the available data shows a 3.7% rise in dog thefts in the UK, from 1,573 to 1,631. When making adjustments for the number of police forces providing data (which decreased over the period), the estimated national figures suggest there may have been more significant rise of up to 44.2%.
While we cannot assume that the forces who supplied data are representative of all 45 regional forces, if this were the case, it would equate to 2,212 recorded dog thefts in 2020, 2,645 in 2021, and 3,191 in 2022.
There was a lot of variation between different areas. For example, Cambridgeshire, Gwent and Northumbria police forces experienced increases of 36%, 49% and 80% respectively in the number of recorded dog thefts between 2020 and 2021.
Monthly analysis of data from regional police forces and DogLost, show that the number of reports of stolen dogs started to go up when the UK entered its first national lockdown and again during part of the third lockdown. But the average number of police-recorded dog thefts was actually slightly higher outside of lockdown periods than during them between 2020 and 2022.
However, in contrast with police trends, DogLost data shows a 65.2% drop in dogs reported stolen on DogLost’s website in 2022 compared to 2020. Lower DogLost numbers may reflect limited visibility or presence of their networks, the use of alternative lost and stolen dog services, or reluctance to share personal details online due to scams targeting dog theft victims.
Our study found that, overall, there probably was an increase in dog theft from
2020 to 2022, following already identified increases in the preceding years. This rise was probably driven by a combination of opportunity (more dogs, higher value) and situational factors (accessibility, dogs unattended in gardens while owners were inside).
Our evidence does not support the notion of a widespread epidemic as portrayed by the media. However, increased media interest probably amplified awareness of the issue, and influenced the creation of the Pet Theft Taskforce, a UK government initiative set up in May 2021 to investigate and tackle dog thefts.
However, there is potential good news. Our ongoing research suggests the number of police-recorded dog thefts decreased slightly in 2023, and again in 2024. This is supported by research from pet insurer Direct Line, which has estimated a 21% decrease in the number of stolen dogs from 2,290 in 2023 to 1,808 in 2024 in the UK.

For children in England with special educational needs and disabilities, an education and health care plan (EHCP) is a central pillar of support. The government is due to set out its educational strategy for children with special educational needs and disabilities in the autumn, though, and has not ruled out scrapping ECHPs. Their removal would signal radical change in how the system works in England.
ECHPs are individualised plans that set out the needs of a particular child and the support they should receive – from education, health services and social care – in order have the best opportunity to thrive. But demand for ECHPs is soaring and providing support is proving financially catastrophic for local authorities.
One of the criticisms of EHCPs is that they prioritise providing children with individual models of support, rather than developing inclusive cultures within schools and within the broader education system. Education secretary Bridget Phillipson has outlined a vision of building a system where more children with special educational needs and disabilities can attend mainstream schools.
But removing ECHPs leads to the possibility of children who need more specialist support missing out.

To secure an ECHP, local authorities carry out a statutory assessment to determine whether a child’s needs warrant additional support. An assessment does not always lead to an EHCP, but if one is issued, it must outline how the child’s needs will be met and the additional resources needed to do so.
These resources might include funding to provide a child with a teaching assistant, funding for equipment and transport to school, or funding to go to a specialist school. This system of support helps school leaders ensure that children and young people have the right support, at the right time.
According to a report published earlier this year, the demand for EHCPs has risen by 140% since 2015. Recent data shows that there are 482,640 children and young people in England with an EHCP.
Many more children have special educational needs, but do not have an ECHP. These pupils are classed as receiving special educational needs support. The percentage of pupils with an EHCP has increased to 5.3%, from 4.8% in 2024. The percentage of pupils with special educational needs support has increased to 14.2%, from 13.6% in 2024.
Despite government investment of £10.7 billion to local authorities in 2024-25, a House of Commons committee report outlines that long waiting times for assessments, as well as to access support such as speech and language therapy, has led to parents losing confidence in the system.
Funding is allocated to each local authority from central government to fund provision in their areas. It is for local authorities, in consultation with their schools, to determine the individual allocation to schools. However, local authorities are struggling to meet the increased demand for EHCPs. Even when funding is allocated through EHCPs, it is not always sufficient to address the needs of those with complex needs.
And funding is not sufficient to meet demand. Local authorities have accumulated huge deficits due to spending exceeding funding, placing some at risk of going bankrupt.
Future plans
Bridget Phillipson has refused to be drawn on whether EHCPs will be axed. “What I can say very clearly,” she has said, “is that we will strengthen and put in place better support for children.”
Building more inclusive schools is obviously one way of achieving this vision. If scrapping EHCPs means less funding for children for special educational needs and disabilities, though, this cannot be the answer. Children need more support, not less, to enable them to thrive.
The solution is for the government to work out what models of inclusion work well in mainstream schools and to decide how these can be resourced and evaluated. Clarity is also needed on inclusion in mainstream schools can be measured in order to assess whether it is working.
Making more support in mainstream schools work also requires an adequate supply of knowledgeable, well-trained teachers. The government is prioritising this through revision to initial teacher education courses, with an emphasis on all teachers being teachers of special educational needs.
If the government doesn’t get this right, the result may be poorer educational and long-term outcomes for pupils with special educational needs and disabilities. It may also lead to issues with teacher recruitment and retention in mainstream schools, particularly if teachers feel that they do not have the level of support in place that they need to meet the needs of their pupils.

The late, great comedian Barry Humphries (of Dame Edna fame) once spoke whimsically about the health benefits of kale. Just one fistful, he joked, contained enough essential vitamins, minerals and trace elements to keep you in a sedentary position in the bathroom for two whole days. Apparently, it wasn’t tasty enough to justify a second helping.
In a world where “superfoods” are relentlessly marketed for their supposed ability to deliver all the nutrients we need, it’s worth asking: which vitamins really are essential? And aside from kale (which I actually rather like), what foods help us meet our daily needs?
Vitamin A
Let’s start at the top. Vitamin A – also known as retinol – is found in foods like eggs, oily fish and dairy products. It plays a crucial role in keeping your skin and immune system healthy.
But it’s probably most famous for supporting vision. Vitamin A binds with light-sensitive pigments in the rod and cone cells of your retina, helping you to see, particularly in low light.
A deficiency in vitamin A, though uncommon in wealthy countries, can lead to serious vision problems and even blindness. Another source of vitamin A is beta-carotene, found in colourful fruits and vegetables like carrots, peppers, spinach and pumpkin. Your body converts beta-carotene into vitamin A, which is why we associate carrots with seeing in the dark.
B1 (thiamin) helps the nervous system and aids digestion. People with chronic alcoholism are especially at risk of deficiency, which can lead to Wernicke-Korsakoff syndrome, a serious neurological disorder that affects memory and movement.
B2 (riboflavin) and B3 (niacin) support similar functions, while B9 (folate) and B12 (cobalamin) are essential for red blood cell production. A lack of either can lead to anaemia.
Folate is especially important in early pregnancy, helping to prevent neural tube defects like spina bifida. That’s why it’s recommended for people who are pregnant or trying to conceive.
You’ll find B vitamins in everything from beans and legumes to meat, fish and dairy; a wide-ranging family of nutrients in a wide-ranging variety of foods.
Vitamin C
The go-to vitamin when we’re under the weather, whether from a virus or a hangover, vitamin C (ascorbic acid) is known as the “healing” vitamin for good reason. It promotes wound healing, supports tissue repair and helps maintain blood vessels and bones.
A deficiency in vitamin C causes scurvy – a condition once common among sailors – with symptoms like fatigue, bruising, depression and gum disease.
Fortunately, vitamin C is found in many different fruits and vegetables, especially citrus fruits. That’s why 19th-century British sailors were given limes to prevent scurvy, earning them the nickname “limeys”.
Vitamin D
Vitamin D is essential for bones, teeth and muscles. It can be absorbed through diet, especially from oily fish, eggs and meat, but your body also makes it in the skin, thanks to sunlight.
In the summer, most people get enough vitamin D from being outside. But in the winter months, diet and, if needed, supplementation become more important.
Deficiency is more common, especially in areas with limited sun exposure. It can lead to soft, weakened bones and symptoms like bone pain, fractures and deformities – including the classic bow-legged appearance. In children, this condition is known as rickets; in adults, it’s called osteomalacia.
Vitamin E
Often overlooked, vitamin E helps protect cells, supports vision and bolsters the immune system. You’ll find it in nuts, seeds and plant oils and it’s usually easy to get enough through a varied diet.
Vitamin F (Sort of)
Not actually a vitamin, “vitamin F” is just a nickname for two omega fatty acids: alpha-linolenic acid (ALA) and linoleic acid (LA). These essential fats support brain function, reduce inflammation, and help maintain healthy skin and cell membranes. Since they’re technically not vitamins, we’ll let them quietly bow out.
Vitamin K
No, you didn’t miss vitamins G through J: they were renamed over the years. But vitamin K is real, and crucial for blood clotting.
Deficiencies are more common in children, and can lead to bruising and bleeding that’s hard to stop. Supplements are effective and given after birth.
All these vitamins are important – and all are found in a wide range of everyday foods. But which single food provides the widest variety?
Kale, oily fish and eggs come in strong at second, third and fourth. But number one is: liver.
Yes, liver. The stuff of childhood dread and overcooked school dinners. But it’s also rich in vitamins A, B, D and K. So rich in Vitamin A, in fact, that it’s advised to eat it only once a week to avoid vitamin A toxicity, and not at all if you’re pregnant. Sometimes, you just can’t win.

In chapter seven of Sylvia Plath’s The Bell Jar (1963), protagonist Esther Greenwood imagines her life branching out before her like a green fig-tree. Each individual fig on the branches represents a different “wonderful future” – a family, a successful career, romance, travel, fame, etc.
High-achieving Esther has innumerable figs she can choose from, yet she envisages herself “starving to death” in the crook of the tree because she can’t make up her mind on which of the figs she should choose.
Her indecision stems from the knowledge that choosing one wonderful future means losing out on the other, equally appealing opportunities. She wants to experience all of them, but knows she cannot, and, in the end, spends so long deciding that every single fig rots and falls to the ground, dead.
By wanting to do everything, Esther misses her chance to do anything at all. This is a metaphor about wasted potential, fears of choosing the wrong pathway, and feeling rushed into making decisions before you truly know what you want. There is little wonder that it appeals to teenagers.
The “fig tree analogy”, as it is known online, is beloved by gen Z and has become a TikTok staple over the last three years. It was first discussed on the platform as part of the 2023 “Roman Empire” meme, with female users citing it as an example of something they constantly think about.
It then reached a new peak in early 2024 thanks to the “my fig tree” trend, in which users (again, predominantly young women) wrote future hopes and dreams onto a stock image of a fig branch in videos featuring accompanying audio of the passage being read aloud.

This trend was, in essence, a way for people to share their dream jobs – with career pathways as varied as “surgeon” and “influencer” sometimes appearing on a single branch. But it also allowed young users to express their anxieties about planning for the future.
In one video, “I can’t help but wonder if I’m going to be truly happy in [my chosen career] forever” is written beside a beautifully illustrated fig tree. I remember feeling this way myself when I read The Bell Jar for the first time in the middle of university applications and big life choices.
When you are young, it can feel like you have only one choice and can never remake it, which is why Plath’s words spoke to me then and seem to be speaking to hundreds now.
But why exactly is this metaphor resonating so strongly with gen Z?
The girls who are participating in the “my fig tree” trend are not subject to the same binary choice of marriage or career that Esther faced. It is now possible to have loads of lovers and then a husband and family, and neither disqualifies you from also being a “brilliant professor” or “amazing editor” or anything else you wish to be.
In The Bell Jar, Plath treats these things as distinct because they would truly have felt that way in Esther’s time of enforced purity and nuclear families. She was, after all, writing pre-second-wave feminism.
It was also referenced in a recent episode of reality dating show Love Island, where it was incorrectly named the “fig theory” and not attributed to Plath.
All of this suggests that the passage has now reached an audience of people who have not read The Bell Jar and see the analogy more as some generic life wisdom than a literary device. Indeed, TikTok videos by self-styled philosophers encouraging watchers to pick any or every fig off the tree instead of being paralysed by indecision like Esther are gaining traction.
While these may prove helpful to Zoomers unsure about their future pathway, I feel that the conversation around this metaphor is increasingly overlooking the fact that Esther is unable to choose a fig because she is depressed.
The real meaning of the fig tree analogy
The Bell Jar may be a novel about coming of age as a woman, but it’s also, at its core, the story of a woman having a breakdown. In the pages preceding the “fig tree analogy”, Esther calls herself “dreadfully inadequate” and claims that “I was only purely happy until I was nine years old”.
So, in the context of the novel, the metaphor can be read as a product of depressive thinking. It is not meant to be a universal truth.
Instead, it represents the subjective thoughts of a narrator who feels herself a failure, despite her plentiful opportunities, because she is mentally ill. Turning Plath’s prose into a theory or philosophy or meme minimises its darker aspects, particularly as the popular TikTok audio that accompanies “fig tree analogy” videos often cuts off before the figs fall, due to the app’s preference for short content.
Some users may well have participated in the “my fig tree” trend without even realising that the quotation ends with Esther losing everything.
Perhaps it should be concerning so many young people relate to a narrator who becomes so overwhelmed by her conflicting ambitions that she attempts to kill herself. I certainly wonder how Plath would feel about her words now being treated as emblematic of a collective female experience. If nothing else, I am sure she would be disappointed at how little has changed in 60 years.

Located in the Peñarol neighborhood of Montevideo, COVIMT 1 was the city’s first mutual aid housing cooperative. It was founded by textile workers, who completed construction of the complex in 1972.Bé Estudio, CC BY-SA
More than 1.8 billion people lack access to adequate and affordable housing. Yet too few countries have taken meaningful steps to ensure dignified housing for their most vulnerable citizens.
We research how cooperative housing can serve as one solution to the affordable housing crisis. There are a variety of cooperative housing models. But they generally involve residents collectively owning and managing their apartment complexes, sharing responsibilities, costs and decision-making through a democratic process.
Other countries, such as El Salvador and Colombia, have struggled to integrate housing cooperatives into their countries’ preexisting housing policies. In fact, although Latin America has a long-standing tradition of community-driven and mutual aid housing, housing cooperatives haven’t taken root in many places, largely due to weak political and institutional backing.
Uruguay is an exception.
With a population of just 3.4 million, the small Latin American nation has a robust network of housing cooperatives, which give access to permanent, affordable housing to citizens at a range of income levels.
An experiment becomes law
Housing cooperatives in Uruguay emerged in the 1960s during a time of deep economic turmoil.
The first few pilot projects delivered outstanding results. Financed through a mix of government funds, loans from the Inter-American Development Bank and member contributions, they were more cost-effective, faster to build and higher in quality than conventional housing.
These early successes played a key role in the passage of Uruguay’s National Housing Law in 1968. This law formally recognized housing cooperatives and introduced a legal framework that supported different models. The most common models to emerge roughly translate to “savings cooperatives” and “mutual aid cooperatives.”
In the savings model, members pool their savings to contribute around 15% of the capital investment. This gives them access to a government-subsidized mortgage to finance the construction. The cooperative then determines how repayment responsibilities are distributed among its members. Typically, members purchase “social shares” in the cooperative, equivalent to the cost of the assigned housing unit. If a member decides to leave the cooperative, their social shares are reimbursed. These shares are also inheritable, allowing them to be passed on to heirs.
In contrast, the mutual aid model enables households without savings to participate by contributing 21 hours per week toward construction efforts. Tasks are assigned to individuals according to their abilities. They can range from manual labor to administrative tasks, such as the ordering of construction materials.
Despite their differences, both models share a fundamental principle: The land and housing units are held collectively and are permanently removed from the private market.
Typically, once cooperatives are established, each household must contribute a monthly fee that covers the repayment of the state’s loan and maintenance costs. In exchange, members have an unlimited and inheritable contract of “use and enjoyment” of a quality apartment. If a member decides to leave, they are partially reimbursed for the contributions they’ve made over time, typically with a 10% deduction that the cooperative keeps.
This ensures that cooperative housing provides long-term security and remains affordable, especially for those at the lowest rungs of the income ladder.
This growth has been possible thanks to state support, federations of cooperatives and nonprofit groups.
The state recognized that the success of housing cooperatives depended on sustained public support. The National Housing Law defined the rights and responsibilities of cooperatives. It also outlined the state’s obligations: overseeing operations, setting criteria for financial assistance and providing access to land.
Beyond organizing and advocating for the right to housing – and human rights more broadly – FUCVAM offers its member cooperatives a wide range of support services, including training to strengthen cooperative management, legal counseling and conflict mediation.
Finally, a vital pillar of this model are the Technical Assistance Institutes, which were also recognized by the National Housing Law. These are independent, nonprofit organizations that advise cooperatives.
Their role is crucial: The construction of large-scale housing projects is complicated. The vast majority of citizens have no prior experience in construction or project management. The success of Uruguay’s cooperative model would be unthinkable without their support.
From the outskirts to the city center
Uruguay’s housing cooperatives have not only expanded, but have also evolved in response to changing needs and challenges.
In their early years, most cooperatives built low-density housing on the outskirts of cities. This approach was largely influenced by the ideals of the Garden City movement, a planning philosophy of the late 19th century that prioritized low-density housing and a balance between development and green spaces. In Uruguay, there was also a cultural preference for single-family homes. And land was more expensive in city centers.
These early cooperatives, however, contributed to urban sprawl, which has a number of drawbacks. Infrastructure has to be built out. It’s harder to reach jobs and schools. There’s more traffic. And single-family homes aren’t an efficient use of land.
Meanwhile, in the 1970s Montevideo’s historic city center started experiencing abandonment and decay. During this period, the country’s shifting socioeconomic landscape created a set of new challenges. More people relied on irregular incomes from informal work, while more single women became heads of households.
In response, housing cooperatives have shown a remarkable ability to adapt.
For women, by women
As urban sprawl pushed development outward, Montevideo’s historic center, Ciudad Vieja, was hemorrhaging residents. Its historic buildings were falling apart.
Seeking to revitalize the area without displacing its remaining low-income residents, the city saw housing cooperatives as a solution.
This spurred the creation of 13 mutual aid cooperatives in Ciudad Vieja, which now account for approximately 6% of all housing units in the area.
One of the pioneers of this effort was Mujeres Jefas de Familia, which translates to Women Heads of Household. Known by the acronym MUJEFA, it was founded in 1995 by low-income, single mothers. MUJEFA introduced a new approach to cooperative housing: homes designed, built and governed with the unique needs of women in mind.
Architect Charna Furman spearheaded the initiative. She wanted to overcome the structural inequalities that prevent women from finding secure housing: financial dependence on men, being primary caregivers, and the absence of housing policies that account for single women’s limited access to economic resources.
Remaining in Ciudad Vieja was important to members of MUJEFA. Its central location allowed them to be close to their jobs, their kids’ schools, health clinics and a close-knit community of friends and family.
However, the project faced major hurdles. The crumbling structure the group acquired in 1991 – an abandoned, heritage-listed building – needed to be transformed into 12 safe, functional apartments.
The cooperative model had to adapt. Municipal authorities temporarily relaxed certain regulations to allow older buildings to be rehabbed as cooperatives. There was also the challenge of organizing vulnerable people – often long-time residents at risk of eviction, who were employed as domestic workers or street vendors – into groups that could actively participate in the renovation process. And they had to be taught how to retrofit an older building.
Today, 12 women with their children live in the MUJEFA cooperative. It’s a compelling example of how cooperative housing can go beyond simply putting a roof over families’ heads. Instead, it can be a vehicle for social transformation. Women traditionally excluded from urban planning were able to design and construct their own homes, creating a secure future for themselves and their children.
Building up, not out
COVIVEMA 5, completed in 2015, was the first high-rise, mutual aid cooperative in a central Montevideo neighborhood. Home to around 300 residents, it’s made up of 55 units distributed across two buildings.
Members participated in the building process with guidance from the Centro Cooperativista Uruguayo, one of the oldest and most respected Technical Assistance Institutes. Architects had to adapt their designs to make it easier for regular people with little experience in construction to complete a high-rise building. Cooperative members received specialized training in vertical construction and safety protocols. While members contributed to the construction, skilled labor would be brought in when necessary.
Members of the cooperative also designed and built Plaza Luisa Cuesta, a public square that created open space in an otherwise dense neighborhood for residents to gather and socialize.
Housing cooperatives are neither public nor private. They might be thought of as an efficient and effective “third way” to provide housing, one that gives residents a stake in their homes and provides long-term security. But their success depends upon institutional, technical and financial support.

Students pick up on AI-infused apps quickly, but generative AI appears to require more reflection on how to use technology.Hill Street Studios via Getty Images
The tech world says generative artificial intelligence is essential for the future of work and learning. But as an educator, I still wonder: Is it really worth bringing it into the classroom? Will these tools truly help students learn, or create new challenges we haven’t yet faced?
Like many other people in higher education, I was skeptical but knew I couldn’t ignore it. So, instead of waiting for all the answers, I decided to dive in and discover what preparing students for an AI-powered world really means beyond the hype. Last semester, I developed a business technology class where the latest generative AI tools were woven into the curriculum.
What I found is that AI productivity products have a learning curve, much like other applications that students, and ultimately white-collar workers, use in knowledge work. But I needed to adjust how I taught the class to emphasize critical thinking, reflection on how these tools are being used and checks against the errors they produce.
The project
It’s no secret that generative AI is changing how people work, learn and teach. According to the 2025 McKinsey Global Survey on AI, 78% of respondents said their organizations use AI in at least one business function, and many are actively reskilling their workforce or training them with new skills to meet the demands of this shift.
As program director of the Business Information Technology bachelor’s degree program at the University of Wisconsin-Stout, Wisconsin’s polytechnic university, I spend a lot of time thinking about how to prepare students for the workplace. I’m also an AI enthusiast, but a skeptical one. I believe in the power of these tools, but I also know they raise questions about ethics, responsibility and readiness.
So, I asked myself: How can I make sure our students are ready to use AI and understand it?
In spring 2025, University of Wisconsin-Stout launched a pilot for a small group of faculty and staff to explore Microsoft 365 Copilot for business. Since it works alongside tools such as Word, Excel, Outlook, PowerPoint, OneDrive and Teams, which are products our students already use, I saw an opportunity to bring these latest AI features to them as well.
To do that, I built an exploratory project into our senior capstone course. Students were asked to use Copilot for Business throughout the semester, keep a journal reflecting on their experience and develop practical use cases for how AI could support them both as students and future professionals. I didn’t assign specific tasks. Instead, I encouraged them to explore freely.
My goal wasn’t to turn them into AI experts overnight. I wanted them to build comfort, fluency and critical awareness about how and when to use AI tools in real-world contexts.
What my students and I learned
What stood out to me the most was how quickly students moved from curiosity to confidence.
Many of them had already experimented with tools such as ChatGPT and Google Gemini, but Copilot for Business was a little different. It worked with their own documents, emails, meeting notes and class materials, which made the experience more personal and immediately relevant.
In their journals, students described how they used Copilot to summarize Teams video meetings, draft PowerPoint slides and write more polished emails. One student said it saved them time by generating summaries they could review after a meeting instead of taking notes during the call or rewatching a recording. Another used it to check their assignment against the rubric – a scoring tool that outlines the criteria and performance levels for assessing student work – to help them feel more confident before submitting their work.

Several students admitted they struggled at first to write effective prompts – the typed requests that guide the AI to generate content – and had to experiment to get the results they wanted. A few reflected on instances where Copilot, like other generative AI tools, produced inaccurate or made-up information, or hallucinations, and said they learned to double-check its responses. This helped them understand the importance of verifying AI-generated content, especially in academic and professional settings.
Some students also said they had to remind themselves to use Copilot instead of falling back on other tools they were more familiar with. In some cases, they simply forgot Copilot was available. That feedback showed me how important it is to give students time and space to build new habits around emerging technologies.
What’s next
While Copilot for Business worked well for this project, its higher cost compared with previous desktop productivity apps may limit its use in future classes and raises ethical questions about access.
That said, I plan to continue expanding the use of generative AI tools across my courses. Instead of treating AI as a one-off topic, I want it to become part of the flow of everyday academic work. My goal is to help students build AI literacy and use these tools responsibly and thoughtfully, as a support for their learning, not a replacement for it.
Historically, software programs enabled people to produce content, such as text documents, slides or the like, whereas generative AI tools produce the “work” based on user prompts. This shift requires a higher level of awareness about what students are learning and how they’re engaging with the materials and the AI tool.
This pilot project reminded me that integrating AI into the classroom isn’t just about giving students access to new tools. It’s about creating space to explore, experiment, reflect and think critically about how these tools fit into their personal and professional lives and, most importantly, how they work.
As an educator, I’m also thinking about the deeper questions this technology raises. How do we ensure that students continue developing original thoughts and critical thinking when AI can easily generate ideas or content? How can we preserve meaningful learning while still taking advantage of the efficiency these tools offer? And what kinds of assignments can help students use AI effectively while still demonstrating their own thinking?
These questions aren’t easy, but they are important. Higher education has an important role to play in helping students use AI and understand its impact and their responsibility in shaping how it’s used.
Striking the right balance between fostering original thought and critical thinking with AI can be tricky. One way I’ve approached this is encouraging students to first create their content on their own, then use AI for review. This way, they maintain ownership of their work and see AI as a helpful tool rather than a shortcut. It’s all about knowing when to leverage AI to refine or enhance their ideas.
One piece of advice I received that really stuck with me was this: Start small, be transparent and talk openly with your students. That’s what I did, and it’s what I’ll continue doing as I enter this next chapter of teaching and learning in the age of AI.

Every few years, the tires on your car wear thin and need to be replaced. But where does that lost tire material go?
The answer, unfortunately, is often waterways, where the tiny microplastic particles from the tires’ synthetic rubber carry several chemicals that can transfer into fish, crabs and perhaps even the people who eat them.
We are analytical and environmental chemists who are studying ways to remove those microplastics – and the toxic chemicals they carry – before they reach waterways and the aquatic organisms that live there.
Tires shed tiny microplastics as they move over roadways. Rain washes those tire wear particles into ditches, where they flow into streams, lakes, rivers and oceans.
Researchers in 2020 found that more than half of the coho salmon returning to streams in Washington state died before spawning, largely because of 6PPD-Q, a chemical stemming from 6PPD, which is added to tires to help keep them from degrading.
In a study in China, the same chemical, 6PPD-Q, was also found in the urine of children and adults. While the effects of this chemical on the human body are still being studied, recent research shows that exposure to this chemical could harm multiple human organs, including the liver, lungs and kidneys.
In Oxford, Mississippi, we identified more than 30,000 tire wear particles in 24 liters of stormwater runoff from roads and parking lots after two rainstorms. In heavy traffic areas, we believe the concentrations could be much higher.
At the University of Mississippi, we are experimenting with sustainable ways of removing tire wear particles from waterways with accessible and low-cost natural materials from agricultural wastes.
The idea is simple: Capture the tire wear particles before they reach the streams, rivers and oceans.
In a recent study, we tested pine wood chips and biochar – a form or charcoal made from heating rice husks in a limited oxygen chamber, a process known as pyrolysis – and found they could remove approximately 90% of tire wear particles from water runoff at our test sites in Oxford.

We designed a biofiltration system using biochar and wood chips in a filter sock and placed it at the mouth of a drainage outlet. Then we collected stormwater runoff samples and measured the tire wear particles before and after the biofilters were in place during two storms over the span of two months. The concentration of tire wear particles was found to be significantly lower after the biofilter was in place.
We believe this approach holds strong potential for scalability to mitigate tire wear particle pollution and other contaminants during rainstorms.
Since biochar and wood chips can be generated from agricultural waste, they are relatively inexpensive and readily available to local communities.
Long-term monitoring studies will be needed, especially in heavy traffic environments, to fully determine the effectiveness and scalability of the approach. The source of the filtering material is also important. There have been some concerns about whether raw farm waste that has not undergone pyrolysis could release organic pollutants.
Like most filters, the biofilters would need to be replaced over time – with used filters disposed of properly – since the contaminants build up and the filters degrade.
Plastic waste is harming the environment, the food people eat and potentially human health. We believe biofilters made from plant waste could be an effective and relatively inexpensive, environmentally friendly solution.

The Trump administration is decreasing the attention federal regulators pay to pipeline leaks. But leaks from natural gas pipelines don’t just waste energy and warm the planet – they can also make the air more dangerous to breathe. That air pollution threat grows not just in the communities where the leaks happen but also as far as neighboring states, as our analysis of gas leaks and air pollution levels across the U.S. has found.
For instance, in September 2018 the Merrimack Valley pipeline explosion in Massachusetts, which released roughly 2,800 metric tons of methane, damaged or destroyed about 40 homes and killed one person. We found that event caused fine-particle air pollution concentrations in downwind areas of New Hampshire and Vermont to spike within four weeks, pushing those areas’ 2018 annual average up by 0.3 micrograms per cubic meter. That’s an increase of about 3% of the U.S. EPA’s annual health standard for PM2.5. Elevated air pollution then showed up in New York and Connecticut through the rest of 2018 and into 2019.
In our study, we examined pipeline leak data from the U.S. Pipeline and Hazardous Materials Safety Administration from 2009 to 2019 and data about the state’s level of small particulate matter in the air from Columbia University’s Center for International Earth Science Information Network. We also incorporated, for each state, data on environmental regulations, per-capita energy consumption, urbanization rate and economic productivity per capita.
In simple terms, we found that in years when a state – or its neighboring states – experienced more methane leak incidents, that state’s annual average fine-particle air pollution was measurably higher than in years with fewer leaks.

Methane’s role in fine‑particle formation
Natural gas is primarily made of methane, a powerful greenhouse gas. But methane also helps set off chemical reactions in the air that lead to the formation of tiny particles known as PM2.5 because they are smaller than 2.5 micrometers (one ten-thousandth of an inch). They can travel deep into the lungs and cause health problems, such as increasing a person’s risk of heart disease and asthma.
So, when natural gas leaks, energy is wasted, the planet warms and air quality drops. These leaks can be massive, like the 2015 Aliso Canyon disaster in California, which sent around 100,000 metric tons of methane into the atmosphere.
But smaller leaks are also common, and they add up, too: Because the federal database systematically undercounts minor releases, we estimate that undocumented small leaks in the U.S. may total on the order of 15,000 metric tons of methane per year – enough to raise background PM2.5 by roughly 0.1 micrograms per cubic meter in downwind areas. Even this modest increase can contribute to health risks: There is no safe threshold for PM2.5 exposure, with each rise of 1 microgram per cubic meter linked to heightened mortality from cardiovascular and respiratory diseases.
The most direct way to reduce this problem is to reduce the number and quantity of methane leaks from pipelines. This could include constructing them in ways or with materials or processes that are less likely to leak. Regulations could create incentives to do so or require companies to invest in technology to detect methane leaks quickly, as well as encourage rapid responses when a leak is identified, even if it appears relatively small at first.
Reducing pipeline leaks would not just conserve the energy that is contained in the methane and reduce the global warming that results from increasing amounts of methane in the atmosphere. Doing so would also improve air quality in communities that are home to pipelines and in surrounding areas and states.

The coach, the specialized equipment, the carefully tailored exercise regimen – they’re all key to athletic performance. But imagination might be an unexpected asset when it comes to playing sports.
The idea that athletic achievement depends on the mind isn’t new. Sport psychologists have known for years that working with an athlete on their mental game – visualizing the skill, kinesthetically feeling the swing – has a positive impact on actual performance. But these mental simulations draw only upon mental imagery – seeing and feeling the physical goals in the mind’s eye. Imagination offers a much wider range of possibilities.
What if your game could be helped by an imaginary friend?
In a recent retrospective study of college students, we discovered that imagination comes in handy in athletics in ways that are surprisingly social. The creation of what we termed imaginary athletes – a person or being that a child imagined in the context of athletics – enabled and motivated athletic play, especially for children between the ages of about 6 and 12. Imaginary athletes also provided companionship during athletic play.
The most basic form of an imaginary athlete might be a wall, fence or even tree that makes a good opponent in a pinch. For a child or adolescent practicing a sport alone, a surface that provides a ball return or a steady target for a throw gives opportunities for practice usually requiring other players.
Is it any wonder, then, if the branches of the tree start to resemble a wide receiver’s arms, or an invisible goalie emerges in front of the fence? Solitary play might be a lot more fun if a make-believe teammate could provide an assist, or an invisible coach could appear and shout instructions during practice.
The college students in our study reported that such support, even if imaginary, made them play a little longer or try a little harder as kids.
About 41% of our sample of 225 college students reported creating at least one imaginary athlete at some point in middle childhood or early adolescence. Most, but not all, of these beings fell into three categories based on their characteristics.
The first we called placeholders, such as ghost runners. They are typically generic, amorphous, imaginary teammates created by groups of children when not enough real players are available.
The second type functioned as what we named athletic tools. They helped kids focus on their performance and improve their skills, usually by providing a worthy competitor, sometimes based on an admired professional athlete. The skills of athletic tools were often just above those of the child, drawing out the desire to be better, stronger, faster.
Social relationships, our name for the third kind of imaginary athlete, primarily served emotional functions, relieving loneliness and providing the child or adolescent with a sense of belonging, safety or companionship as they engaged in their sport.
Students who remembered imaginary athletes differed from their peers in two ways. First, more men than women reported creating these imaginary beings, possibly owing to the greater investment in and importance of athletics among boys versus girls. Second, people with imaginary athletes scored higher than those without on a current-day measure of predilection for imagination, but they were not more likely to report having created a make-believe friend or animal as a child.
Imagination is a valuable power
Creating an imaginary other might seem like a quirky, perhaps even childish, addition to sports practice. But actually, this behavior is entirely logical. After all, imagination is the core of human thought. Without it, we couldn’t conceptualize anything outside of the present moment that wasn’t already stored in memory. No thinking about the future, no consideration of multiple outcomes to a decision, no counterfactuals, daydreams, fantasies or plans.
Why wouldn’t people apply such a fundamental tool of day-to-day thought in athletic contexts? Participation in sports is common, especially among school-age kids, and many college students in our study described drawing upon their imaginations frequently when playing sports, especially when doing so in their free time.
The creation of imaginary athletes is also unsurprising because it’s one of myriad ways that imagination enhances people’s social worlds throughout their lives. Above all else, social relationships are what matter most to people, and using imagination in thinking about them is common. For instance, people imagine conversations with others, particularly those close to them, sometimes practicing the delivery of bad news or envisioning the response to a proposal of marriage.
In early childhood, kids create imaginary companions who help them learn about friendship and other’s perspectives. And in adolescence, when people focus on developing their autonomy and their own identities, they create parasocial relationships that let them identify with favorite celebrities, characters and media figures. Even in older age, some widows and widowers imagine continued relationships with their deceased spouses. These “continuing bonds” are efforts to cope with loss through imaginary narratives that are fed by and extrapolate upon years of interactions.
At each point in their developmental trajectory, people might recruit imagination to help them understand, manage, regulate and enjoy the social aspects of life. Imaginary athletes are merely one manifestation of this habit.
Because so many children and adolescents spend a lot of time engaged in sports, athletics can be a major environment for working on the developmental tasks of growing up. As children learn about functioning as part of a group, forming, maintaining and losing friendships, and mastering a range of skills and abilities, imaginary athletes provide teammates, coaches and competitors tailored to the needs of the moment.
Of course, an imaginary athlete is but one tool that children and adolescents might use to address developmental tasks such as mastering skills or negotiating peer relationships. Children who aren’t fantasy-prone might create complex training regimens to practice their skills, and they might manage their friendships by talking through problems with others.
But some report that turning inward generated real athletic and social benefits. “I got confidence out of my [imaginary athletes],” reported one participant. “If I could imagine beating someone, and [winning], then I felt like I could do anything.”

After South Africa’s first democratic elections in 1994, there was significant optimism about police reform in the country. Impressive steps were taken to bring the South African Police Service under civilian control and to create a service responsive to calls for assistance from the public.
During the apartheid period, South Africa’s police worked to preserve the political order and pursue political opponents. It did not focus on dealing with crime. This is why the achievements of the 1990s are so important. For the first time, black South Africans could call upon officers to respond to personal emergencies. This period also saw a drop in crime levels.
However, this promising early transformation was interrupted. The appointment of Jackie Selebi as national police commissioner in 2000 heralded a new era. Selebi was an African National Congress (ANC) insider. The ANC originated as a liberation movement and has governed the country since 1994.
Selebi had served as the head of the ANC’s Youth League in the 1980s, when it was banned. In 1987 he was appointed to the organisation’s national executive committee, its highest decision-making organ.
His appointment as police commissioner was the start of significant change in the purpose of policing. It marked the end of the focus on civilian control of the police force and prosecuting authorities. As an ANC insider, Selebi led efforts to establish party control over the police.
Other telling developments ensued. The Scorpions were disbanded in 2009 by acting president Kgalema Motlanthe. The unit’s job was to pursue high-profile cases against senior ANC politicians (among others).
The police became increasingly entangled in the ANC’s internal political conflicts. At the same time the office of the national police commissioner experienced high turnover due to intense political manoeuvring. Between 2009 and 2022, there were seven national commissioners.
Recent developments have once again brought the intermingling of police work and power battles in the ANC to the fore. In early July 2025, Lieutenant General Nhlanhla Mkhwanazi, the commissioner of police in the province of KwaZulu-Natal, made some startling claims. He called a press conference and, wearing camouflage uniform, he implicated the minister of police, Senzo Mchunu, together with the deputy national commissioner for crime detection, in a scheme to close down investigations into political assassinations in the province.
President Cyril Ramaphosa rushed back from a meeting of the Brics countries in Brazil to attend to the matter. He announced that the police minister had been placed on leave with immediate effect. He also announced a judicial inquiry into the allegations.
I have conducted research into South Africa’s security apparatus over the last decade. Based on this work, and new research forthcoming in the Journal of Southern African Studies done with Jelena Vidojevic, co-founder of the New South Institute, it is clear that elite contestation in the ANC is intensifying.
In other words, the ability of internal party structures to manage gatekeeping is declining. Many of the people involved are indifferent or even hostile to South Africa’s democratic and constitutional order.
As the ability of some political elites to access state resources through the party declines, some are linked with organised criminal networks. Organised crime has been on the edges of South African politics. It now risks taking a more central role.
In this environment, the police service will often be the thin (blue) line between multiparty contestation according to constitutional rules and the criminalisation of politics in South Africa.
The shift
Large organisational changes within the police vividly illustrate this shift away from its core function.
The Visible Policing programme was meant to meant to deter crime through patrols, checkpoints and roadblocks. But, instead, there was a steady decline in resource allocation. Employee numbers dropped between 2015 and 2021.
Detective services and crime intelligence also experienced such declines.
Conversely, employee numbers in the Protection and Security Services programme, responsible for providing bodyguards to politicians, increased sharply between 2014 and 2016.
Evidence heard by the commission of inquiry into state capture suggested that some officers and budgets in the service were even used to supply President Jacob Zuma and other politicians with what amounted to a private militia.
This reorientation of resources coincided with a rise in crime across the country, a decline in arrests by 24.5%, and a drop in the police’s efficacy in solving crimes.
Furthermore, a politicised police leadership effectively stopped policing various categories of crime. This was particularly true of offences like fraud, corruption, and certain types of theft, and particularly when politically connected persons were involved.
The state capture commission heard extensive evidence about the failure of the police to pursue politically sensitive investigations. Investigations into senior officials were frequently frustrated or impeded, and cases at state-owned enterprises were abandoned.
This shows how police resources were actively redirected as weapons of elite competition, pursuing political enemies and protecting allies within the ruling party.
Mkhwanazi’s claims, if substantiated, suggest that this political policing remains entrenched.
What now?
Ramaphosa has announced the appointment of Firoz Cachalia as the acting minister of police. Cachalia, a well regarded legal academic, served as ANC minister for community safety. Between 2019 and 2022 he was part of the ANC’s national executive committee.
His appointment raises serious questions.
If the core problem with the police is that it has become embroiled in ANC internal politics, having an ANC insider head the ministry of police (even if only on an acting basis) threatens only to compound the problem.
Moreover, South Africans have already witnessed a long and expensive judicial inquiry into state capture. And despite extensive evidence of police failure to pursue politically sensitive investigations, nothing concrete has come of it.
How likely is it that this new initiative will be any different, especially if those investigating it and presiding over key institutions are themselves ANC insiders?
To depoliticise the police service and redirect its attention and activities towards crime and emergencies, a crucial first step is to reconsider the appointment processes for the national police commissioner and other top managers.
Under the current system the president has sole discretion. This bakes party-political considerations into the decision-making process.
Without structural changes, genuine democratic policing will remain an elusive ideal.
In 2024/25 the murder rate in South Africa stood at 42 per 100,000, among the highest in the world and close to levels not seen since the early 2000s.
At the very least, the minister of police must not be an ANC insider. Democratic renewal in South Africa requires bringing the police firmly under parliamentary control.

If Rupert Murdoch becomes a white knight standing up to a rampantly bullying US president, the world has moved into the upside-down.
This is, after all, the media mogul whose US television network, Fox News, actively supported Donald Trump’s Big Lie about the 2020 presidential election result and paid out a US$787 million (about A$1.2 billion) lawsuit for doing so.
It is also the network that supplied several members of Trump’s inner circle, including former Fox host, now controversial Defense Secretary, Pete Hegseth.
But that is where we are after Trump filed a writ on July 18 after Murdoch’s financial newspaper, The Wall Street Journal, published an article about a hand-drawn card Trump is alleged to have sent to sex offender Jeffrey Epstein in 2003. The newspaper reported:
A pair of small arcs denotes the woman’s breasts, and the future president’s signature is a squiggly “Donald” below her waist, mimicking pubic hair.
The Journal said it has seen the letter but did not republish it. The letter allegedly concluded:
Happy Birthday – and may every day be another wonderful secret.
The card was apparently Trump’s contribution to a birthday album compiled for Epstein by the latter’s partner Ghislaine Maxwell, who is serving a 20-year sentence after being found guilty of sex trafficking in 2021.
Trump was furious. He told his Truth Social audience he had warned Murdoch the letter was fake. He wrote, “Mr Murdoch stated that he would take care of it but obviously did not have the power to do so,” referring to Murdoch handing leadership of News Corporation to his eldest son Lachlan in 2023.
Trump is being pincered. On one side, The Wall Street Journal is a respected newspaper that speaks to literate, wealthy Americans who remain deeply sceptical about Trump’s radical initiative on tariffs, which it described in an editorial as “the dumbest trade war in history”.
On the other side is the conspiracy theory-thirsty MAGA base who have been told for years that there was a massive conspiracy around Epstein’s apparent suicide in 2019 that included the so-called deep state, Democrat elites and, no doubt, the Clintons.
Trump, who loves pro wrestling as well as adopting its garish theatrics, might characterise his lawsuit against Murdoch as a smackdown to rival Hulk Hogan vs Andre the Giant in the 1980s.
To adopt wrestling argot, though, it is a rare battle between two heels.
A friendship of powerful convenience
Murdoch and Trump’s relationship is longstanding but convoluted. The key to understanding it is that both men are ruthlessly transactional.
Exposure in Murdoch’s New York Post in the 1980s and ‘90s was crucial to building Trump’s reputation.
Not that Murdoch particularly likes Trump. Yes, Murdoch attended his second inauguration, albeit in a back row behind the newly favoured big tech media moguls. He was also seen sitting in the Oval Office a few days later looking quite at home.
But this was pure power-display politics, not the behaviour of a friend.
Remember Murdoch’s derision on hearing Trump was considering standing for office before the 2016 election, and his promotion of Ron De Santis in the primaries before Trump’s second term. Murdoch’s political hero has always been Ronald Reagan. Trump has laid waste to the Republican Party of Reagan.
Murdoch knows what the rest of sane America knows: Trump is downright weird, if not dangerous. This, of course, only makes Murdoch’s complicity in Trump’s rise to power, and Fox News’ continued boosterism of Trump, all the more appalling.
But, in keeping with Murdoch’s relationship to power throughout his career, what he helps make, he also helps destroy. Perhaps now it’s Trump’s turn to be unmade. As a former Murdoch lieutenant told The Financial Times over the weekend:
he’s testing out: Is Trump losing his base? And where do I need to be to stay in the heart of the base?
And here is Murdoch’s great advantage, and his looming threat.
A double-edged sword
The advantage comes with the scope of Murdoch’s media empire, which operates like a federation of different mastheads, each with their own market and aspirations. While Fox News panders to the MAGA base, and The New York Post juices its New York audience, The Wall Street Journal speaks, and listens, to business. Each audience has different needs, meaning they’re often presented with the same news in very different ways, or sometimes different news entirely.
Like a federation, though, News Corp uses its various operations to drive the type of change that affects all its markets.
It might work like this. The Wall Street Journal breaks a story that’s so shocking it begins to chip away at MAGA’s unquestioning loyalty of Trump. This process is, of course, willingly aided by the rest of the media. The resulting groundswell eventually allows Fox News and the Post to tentatively follow their audiences into questioning, and then perhaps criticising, Trump.

The threat is that before that groundswell builds, Murdoch is seriously vulnerable to criticism from a still dominant Trump, who can turn conspiracy-prone audiences away from Fox News with just a social media post. Trump has already been busy doing just that, saying he is looking forward to getting Murdoch onto the witness stand for his lawsuit.
If the Fox audience decides it’s the proprietor who’s behind this denigration of Trump, they may decide to boycott their own favoured media channel, even though Fox’s programming hasn’t yet started questioning Trump.
The Murdochs’ fear of audience backlash was a major factor in Fox’s promulgation of the Big Lie after Trump’s defeat in 2020. The fear their audience might defect to Newsmax or some other right-wing media outfit is just as real today.
History littered with fakery
We also need to consider that Trump might be right. What if the letter is a fake?
Murdoch has form when it comes to high-profile exposés that turn out to be fiction. Who can forget the Hitler Diaries in 1983, which we now know Murdoch knew were fake before he published.
Think also of the Pauline Hanson photos, allegedly of her posing in lingerie, all of which were quickly proved to be fake after they were published by Murdoch’s Australian tabloids in 2009.
There was also The Sun’s despicable and wilfully wrong campaign against Elton John in 1987 and the same paper’s continueddenigration of the people of Liverpool following the Hillsborough stadium disaster in 1989.
But while Murdoch’s News Corp has a history of confection and fakery, the Wall Street Journal has a reputation for straight reportage, albeit through a conservative lens. Since Murdoch bought it in 2007, it has been engaged in its own internal battle for editorial standards.
Media rolling over
What Trump won’t get from Murdoch is the same acquiescence he’s enjoyed from America’s ABC and CBS networks, which have both handed over tens of millions of dollars in defamation settlements following dubious claims by Trump about the nature of their coverage.
In December 2024, ABC’s owner Disney settled and agreed to pay US$15 million (A$23 million) to Trump’s presidential library. The president sued after a presenter said Trump was found guilty of raping E. Jean Carroll.
Trump had actually been found guilty by a jury in a civil trial of sexually abusing and defaming Carroll and was ordered to pay her US$5 million (A$7.6 million).
CBS’ parent company, Paramount, did similarly after being sued by the president, agreeing in early July to settle and pay US$16 million (A$24.5 million) to Trump’s library. This was despite earlier saying the case was “completely without merit”.
Beware the legal microscope
From Trump’s viewpoint, two prominent media companies have been cowed. But his campaign against critical media doesn’t stop there.
Last week, congress passed a bill cancelling federal funding for the country’s two public-service media outlets, the Public Broadcasting Service (PBS) and National Public Radio (NPR).
Also last week, CBS announced the cancellation of Stephen Colbert’s stridently critical comedy show, although CBS claims this is just a cost-cutting exercise and not about appeasing a bully in the White House.
Presuming the reported birthday letter is real, Murdoch will not bend so easily. And that’s when it will be important to pay attention, because at some point Trump’s lawyers will advise him about the dangers of depositions and discovery: the legal processes that force parties to a dispute to reveal what they have and what they know.
If the Epstein files do implicate Trump, the legal fight won’t last long and the media campaign against him will only intensify.
Right now we have the spectre of Murdoch joining that other disaffected mogul, Elon Musk, in a moral crusade against Trump, the man they both helped make. The implications are head-spinning.
As global bullies, the three of them probably deserve each other. But we, the public, surely deserve better than any of them.

Monitor lizards, also known in Australia as goannas, are some of the most iconic reptiles on the continent. Their lineage not only survived the mass extinction that ended the reign of non-avian dinosaurs, but also gave rise to the largest living lizards on Earth.
Today, these formidable creatures pace through forests and scrublands, flicking their tongues as they go.
A new study published in the Zoological Journal of the Linnean Society looks beneath their skin. For the first time, it reveals hidden bone structures that may hold the key to the evolutionary success of goannas in Australia.
An essential organ
The skin is an organ essential for survival. In some animals, it includes a layer of bone plates embedded among the skin tissue. Think of the armour-like plates in crocodiles or armadillos: these are osteoderms.
Their size ranges from microscopic to massive, with the back plates of the stegosaurus as the most impressive example.
We have only just started to understand these enigmatic structures. Osteoderms can be found in animal lineages that diverged up to 380 million years ago. This means these bone plates would have evolved independently, just like active flight did in birds, pterosaurs and bats.
But what is their purpose? While the advantage of flight is undisputed, the case is not as clear for osteoderms.
The most obvious potential would be for defence – protecting the animal from injuries. However, osteoderms may serve a far broader purpose.
In crocodiles, for example, they help with heat regulation, play a part in movement, and even supply calcium during egg-laying. It is the interplay of these poorly understood functions that has long made it difficult to pinpoint how and why osteoderms evolved.

A cutting-edge technique
To help resolve this enigma, we had to go back to the beginning.
Surprisingly, to date science has not even agreed on which species have osteoderms. Therefore, we assembled an international team of specialists to carry out the first large-scale study of osteoderms in lizards and snakes.
We studied specimens from scientific collections at institutions such as the Florida Museum of Natural History, the Natural History Museum in Berlin, and Museums Victoria.
However, we soon learnt that this came with challenges. Firstly, the presence of osteoderms can vary dramatically between individuals of the same species. Secondly, there is no guarantee that osteoderms are sufficiently preserved in all specimens.
Most importantly, they are buried deep within skin tissue and invisible to the naked eye. Traditionally, finding them meant destroying the specimen.
Instead, we turned to micro-computed tomography (micro-CT), an imaging technique similar to a medical CT scan, but with much higher resolution. This allowed us to study even the tiniest anatomical structures while keeping our specimens intact.

Using computer-generated 3D models, we then digitally explored the bodies of lizards and snakes from all parts of the world. Incorporating data from prior literature, we processed almost 2,000 such samples in our search for osteoderms.
To illustrate our results, we devised a technique called radiodensity heatmapping, which visually highlights the locations of bone structures in the body.
For the first time, we now have a comprehensive catalogue showing where to find osteoderms in a large and diverse group; this will inform future studies.

Not just anatomical curiosity
What we found was unexpected. It was thought only a small number of lizard families had osteoderms. However, we encountered them nearly twice as often as anticipated.
In fact, our results show nearly half of all lizards have osteoderms in one form or another.
Our most astonishing finding concerned goannas. Scientists have been studying monitor lizards for more than 200 years. They were long thought to lack osteoderms, except in rare cases such as the Komodo dragon.
So we were all the more surprised when we discovered previously undocumented osteoderms in 29 Australo-Papuan species, increasing their overall known prevalence five times.

This isn’t just an anatomical curiosity. Now that we know Australian goannas have osteoderms, it opens up an exciting new avenue for further studies. This is because goannas have an interesting biogeographic history: when they first arrived in Australia about 20 million years ago, they had to adapt to a new, harsh environment.
If osteoderms in goannas showed up around this time – possibly owing to new challenges from their environment – we’d gain crucial insights into the function and evolution of these enigmatic bone structures.
Not only may we just have found the key to an untold chapter in the goanna story, our findings may also improve our understanding of the forces of evolution that shaped Australia’s unique reptiles as we know them today.

Australia has joined 28 international partners in calling for an immediate end to the war in Gaza and a lifting of all restrictions on food and medical supplies.
Foreign Minister Penny Wong, along with counterparts from countries including the United Kingdom, France and Canada, has signed a joint statement demanding Israel complies with its obligations under international humanitarian law.
The statement condemns Israel for what it calls “the drip feeding of aid and the inhumane killing of civilians” seeking “their most basic need” of water and food, saying:
The suffering of civilians in Gaza has reached new depths. The Israeli government’s aid delivery model is dangerous, fuels instability and deprives Gazans of human dignity […] It is horrifying that over 800 Palestinians have been killed while seeking aid.
Weapon of war
Gazans, including malnourished mothers denied baby formula, face impossible choices as Israel intensifies its use of starvation as a weapon of war.
In Gaza, survival requires negotiating what the United Nations calls aid “death traps”.
According to the UN, 875 Gazans have been killed – many of them shot – while seeking food since the US-backed Gaza Humanitarian Foundation began operating in late May. Another 4,000 have been injured.
Gaza has been described as the “hungriest place on Earth”, with aid trucks being held at the border and the United States destroying around 500 tonnes of emergency food because it was just out of date.
More than two million people are at critical risk of famine. The World Food Programme estimates 90,000 women and children require urgent treatment for malnutrition.
Nineteen Palestinians have starved to death in recent days, according to local health authorities.
We can’t say we didn’t know
After the breakdown of the January ceasefire, Israel implemented a humanitarian blockade on the Gaza Strip. Following mounting international pressure, limited aid was permitted and the controversial Gaza Humanitarian Foundation began operations.
As anticipated, only a fraction of the aid has been distributed.
About 1,600 trucks entered Gaza between May 19 and July 14, well below the 630 trucks needed every day to feed the population.
Israeli ministers have publicly called for food and fuel reserves to be bombed to starve the Palestinian people – a clear war crime – to pressure Hamas to release Israeli hostages.
Famine expert Alex De Waal says Israel’s starvation strategy constitutes a dangerous weakening of international law. It also disrupts norms aimed at preventing hunger being used as a weapon of war:
operations like the Gaza Humanitarian Foundation are a big crack in these principles [that is] not going to save Gaza from mass starvation.
Palestinian organisations were the first to raise the alarm over Israel’s plans to impose controls over aid distribution.
UN Relief Chief Tom Fletcher briefed the UN Security Council in May, warning of the world’s collective failure to call out the scale of violations of international law as they were being committed:
Israel is deliberately and unashamedly imposing inhumane conditions on civilians in the occupied Palestinian territory.
Tom Fletcher briefing the United Nations on the ‘atrocity’ being committed in Gaza.
Since then, clear and unequivocal warnings of the compounding risks of genocide, war crimes, crimes against humanity and ethnic cleansing have intensified from the UN, member states and international law experts.
Weaponising aid
The Gaza Humanitarian Foundation claims it has handed out millions of meals since it began operating in the strip in May. But the UN has called the distribution model “inherently unsafe”.
Near-daily shootings have occurred since the militarised aid hubs began operating. Malnourished Palestinians risking death to feed their families are trekking long distances to reach the small number of distribution sites.
While the foundation denies people are being shot, the UN has called the aid delivery mechanism a “deliberate attempt to weaponise aid” that fails to comply with humanitarian principles and risks further war crimes.
Jewish Physicians for Human Rights has rejected the aid’s “humanitarian” characterisation, stating it “is what systematic harm to human beings looks like”.
Human rights and legal organisations are calling for all involved to be held accountable for complicity in war crimes that “exposes all those who enable or profit from it to real risk of prosecution”.
Mounting world action
Today’s joint statement follows growing anger and frustration in Western countries over the lack of political pressure on Israel to end the suffering in Gaza.
Polling in May showed more than 80% of Australians opposed Israel’s denial of aid as unjustifiable and wanted to see Australia doing more to support civilians in Gaza.
Last week’s meeting of the Hague Group of nations shows more collective concrete action is being taken to exert pressure and uphold international law.
Th 12 member states agreed to a range of diplomatic, legal and economic measures, including a ban on ships transporting arms to Israel.
The time for humanity is now
States will continue to face increased international and domestic pressure to take stronger action to influence Israel’s conduct as more Gazans are killed, injured and stripped of their dignity in an engineered famine.
This moment in Gaza is unprecedented in terms of our knowledge of the scale and gravity of violations being perpetrated and what failing to act means for Palestinians and our shared humanity.
Now is the time to exert diplomatic, legal and economic pressure on Israel to change course.
History tells us we need to act now – international law and our collective moral conscience requires it.
