For 24 hours a day, seven days a week since November 2000, NASA and its international partners have sustained a continuous human presence in low-Earth orbit, including at least one American – a streak that will soon reach 25 years.

When viewed in the history of spaceflight, the International Space Station is perhaps one of humanity’s most amazing accomplishments, a shining example of cooperation in space among the United States, Europe, Canada, Japan and Russia. But all good things must come to an end.

In 2030, the International Space Station will be deorbited: driven into a remote area of the Pacific Ocean.

I’m an aerospace engineer who has helped build a range of hardware and experiments for the ISS. As a member of the spaceflight community for over 30 years and a 17-year member of the NASA community, it will be hard for me to see the ISS come to an end.

Since the first pieces of the International Space Station were launched in 1998, the station has been home to significant research accomplishments across domains that include materials science, biotechnology, astronomy and astrophysics, Earth science, combustion and more.

Astronauts performing research inside the space station and payload experiments attached to the station’s exterior have generated many publications in peer-reviewed science journals. Some of them have advanced our understanding of thunderstorms, led to improvements in the crystallization processes of key cancer-fighting drugs, detailed how to grow artificial retinas in space, explored the processing of ultrapure optical fibers and explained how to sequence DNA in orbit.

In total, more than 4,000 experiments have been conducted aboard the ISS, resulting in more than 4,400 research publications dedicated to advancing and improving life on Earth and helping forge a path for future space exploration activities.

The ISS has proven the value of conducting research in the unique environment of spaceflight – which has very low gravity, a vacuum, extreme temperature cycles and radiation – to advance scientists’ understanding of a wide range of important physical, chemical and biological processes.

Keeping a presence in orbit

But in the wake of the station’s retirement, NASA and its international partners are not abandoning their outpost in low-Earth orbit. Instead, they are looking for alternatives to continue to take advantage of low Earth orbit’s promise as a unique research laboratory and to extend the continuous, 25-year human presence some 250 miles (402 kilometers) above the Earth’s surface.

In December 2021, NASA announced three awards to help develop privately owned, commercially operated space stations in low-Earth orbit.

For years, NASA has successfully sent supplies to the International Space Station using commercial partners, and the agency recently began similar business arrangements with SpaceX and Boeing for transporting crew aboard the Dragon and Starliner spacecraft, respectively.

Based on the success of these programs, NASA invested more than US$400 million to stimulate the development of commercial space stations and hopefully launch and activate them before the ISS is decommissioned.

Dawn of commercial space stations

In September 2025, NASA issued a draft announcement for Phase 2 partnership proposals for commercial space stations. Companies that are selected will receive funding to support critical design reviews and demonstrate stations with four people in orbit for at least 30 days.

NASA will then move forward with formal design acceptance and certification to ensure that these stations meet NASA’s stringent safety requirements. The outcome will allow NASA to purchase missions and other services aboard these stations on a commercial basis – similar to how NASA gets cargo and crew to the ISS today.

Which of these teams will be successful, and on what timescale, remains to be seen.

While these stations are being built, Chinese astronauts will continue to live and work aboard their Tiangong space station, a three-person, permanently crewed facility orbiting approximately 250 miles (402 km) above the Earth’s surface. Consequently, if the ISS’s occupied streak comes to an end, China and Tiangong will take over as the longest continually inhabited space station in operation: It’s been occupied for approximately four years and counting.

Photos and videos from the ISS allow you to see Earth from above.

In the meantime, enjoy the view

It will be several years before any of these new commercial space stations circle the Earth at around 17,500 miles per hour (28,000 kilometers per hour) and several years before the ISS is deorbited in 2030.

So while you have a chance, take a look up and enjoy the view. On most nights when the ISS flies over, it is simply magnificent: a brilliant blue-white point of light, usually the brightest object in the sky, silently executing a graceful arc across the sky.

Our ancestors could hardly have imagined that one day, one of the brightest objects in the night sky would have been conceived by the human mind and built by human hands.

Detroit’s Gordie Howe bridge is poised to open as truck traffic between US-Canada slows – and low-income residents decide whether to stay or go

Watching the space between two nations shrink became a regular pastime for Detroiters over the past decade as the segments of the Gordie Howe International Bridge gradually grew, extending meter by meter from Ontario on one side and Michigan on the other.

The gap finally closed in July 2024 with the two halves coming together in a long-awaited kiss.

The official grand opening of the bridge was originally scheduled for fall of 2025, but it seems now likely to be delayed into 2026.

I’m a sociologist who has worked alongside neighborhood revitalization projects in Detroit for the past 15 years. I’ve observed the bridge project – and the many tensions around it – from the perspective of adjacent communities of Delray and Mexicantown, communities that are largely hometo low-income Latino, Black and white residents.

The costs and benefits of this binational behemoth are complex and intertwined.

Clearing a chokehold

Boosters on both sides of the border have spoken frequently of the bridge’s expected benefits.

Detroit and Windsor would finally be free of the perpetual chokehold produced by the privately owned Ambassador Bridge.

Auto parts will flow more freely over the border, according to the Cross-Border Institute at the University of Windsor. And the Detroit Greenways Coalition is celebrating that its advocacy led to the inclusion of free pedestrian and bike lanes.

People living close to the existing bridge will gain some relief from truck traffic and pollution. But this burden won’t simply disappear – it will be shifted nearby, where others will have to cope with increased traffic flowing over six lanes 24 hours a day.

A political football

The costs and benefits of the bridge were contested from the beginning.

In the early days, the debate concentrated on who would own the bridge and who would pay for it.

Once just a concept known by the acronym DRIC, or Detroit River International Crossing, the project became real under former Michigan Gov. Rick Snyder. In July 2018, representatives from both Ottawa and Washington broke ground on the bridge situated in an area of Detroit empty enough to contain its significant footprint and bear its weight without fear of sinkholes from underground salt mines.

“Every Michigander should thank every Canadian,” said Snyder at the time, alluding to the agreement that Canadian taxpayers alone would pay for the bridge’s construction in exchange for collecting all the tolls.

The bridge’s designers attempted to honor the cultural and natural history of the region. It was named after the legendary Canadian hockey player who was also a longtime stalwart for the Detroit Red Wings. The bridge’s towers are adorned with murals by First Nations artists.

But serious questions remain.

Today the debates center on whether the Trump administration’s increased tariffs and trade conflicts with Canada could negatively affect the value of the bridge – and if it will ever pay for itself. Even before President Donald Trump took office for the second time, truck traffic on the Ambassador Bridge was down, falling 8% from 2014 to 2024.

One bridge was always a bad idea, (nearly) everyone agreed

Residents and politicians have long agreed that having a single, privately owned bridge connecting Detroit and Windsor was a bad idea. This felt especially apparent after the 9/11 terrorist attacks laid bare the possibility of suddenly losing critical infrastructure.

For many years, travelers’ only other connection between Canada and Detroit has been a tunnel that runs underneath the Detroit River. However, the tunnel doesn’t offer direct access to interstate highways, making it less suitable for commercial trucks.

Adding another bridge makes it harder to disrupt trade and transport.

But the project has had one stalwart critic. Matty Moroun, the trucking billionaire who purchased the Ambassador Bridge in 1979, ferociously protected his asset against potential competition. He actively sought to thwart the construction, launching numerous lawsuits against the state of Michigan and the Windsor-Detroit Bridge Authority, the entity managing construction of the new bridge.

Those lawsuits continued even after Moroun’s death in 2020, as his heirs asserted significant damages to the value of their property.

Was enough done for nearby homeowners?

Others have criticized the attempts to compensate the residents of Delray, a once-vibrant neighborhood that has been impacted by industrialization since the 1960s.

Benefits negotiated for residents and homeowners affected by the construction have not increased as the project’s costs ballooned and the timeline to complete it stretched out.

The cost of the Gordie Howe bridge is now estimated at around $6.4 billion Canadian – or about $US4.7 billion. That is $700 million more than the original projected cost. The project is at least 10 months behind schedule.

Simone Sagovac, director of the SW Detroit Community Benefit Coalition, said they did not anticipate the immense scale of the development and its continued effects on the community.

“That scale affected health and quality of life significantly every day, with years of continuous industrial dust causing sinus problems, headaches, and increasing asthma, and then there will be thousands of daily truck impacts to come,” Sagovac wrote to me in an email.

A baseline health impact assessment, issued in 2019 by University of Michigan researchers working closely with the coalition, expressed concern about the heightened airborne pollution that would likely activate asthma, especially in children. Matching the findings of so many other epidemiological studies, the assessment found that residents living within 500 feet (152 meters) of a truck route reported a significantly higher likelihood of experiencing asthma or allergies affecting their breathing.

Sagovac wrote that the project took 250 homes, 43 businesses and five churches by eminent domain, and “saw the closing of more after.” One hundred families left the neighborhood via a home swap program funded as a result of the benefits agreement administered by a local nonprofit. Two hundred and seventy families remain, but most businesses have left the area over decades of decline.

The families that remain are often long-term residents wanting or needing a cheap place to live and willing to put up with dust, noise and smells from nearby factories and a sewage treatment plant.

“They constantly face illegal dumping and other unanswered crimes, and will face the worst diesel emissions exposure and other trucking and industry impacts,” Sagovac wrote.

Heather Grondin, chief relations officer of the Windsor-Detroit Bridge Authority, wrote in an emailed statement
that they have taken steps to minimize impacts from construction and that they regularly meet with the community to hear concerns.

“Construction traffic is using designated haul routes to minimize community impacts, traffic congestion and wear and tear on existing infrastructure while maximizing public and construction safety,” Grondin wrote.

According to Grondin, cars will be forced to follow a “no idling” rule on the American side to minimize pollution. Other aspects of the Community Benefits Plan included $20,000 in free repairs for 100 homes, planting hundreds of trees and investing in programs addressing food insecurity and the needs of young people and seniors, Grondin wrote.

An updated Health Impacted Assessment is expected to be released later in 2025.

History lost

Lloyd Baldwin, a historian for the Michigan Department of Transportation, was tasked with evaluating whether local landmarks like the legendary Kovacs Bar needed to be preserved.

“Kovacs Bar was one among many working-class bars in the Delray neighborhood but stands out for its roughly eight-decade association as a gathering place for the neighborhood and downriver Hungarian-American community,” Baldwin wrote in one such report.

The bar was nonetheless demolished in November 2017.

This was not MDOT’s only loss. While the agency made some sincere efforts to leverage other benefits for residents who remained, dynamic factors at many levels were out of the agency’s control.

For one thing, the numerous lawsuits filed by the bridge company over parcels of contested land limited MDOT’s ability to talk openly to the public about the land acquisition process.

In the period of legal limbo, Baldwin said, “the neighborhood imploded.”

Baldwin gave the example of the Berwalt Manor Apartments, built in the 1920s and located on Campbell Street near the bridge entrance. MDOT committed to preserve the historic building and proposed to mitigate the environmental impacts on mostly low-income residents by paying for new windows and HVAC units once the bridge was built.

But the speed of development outstripped the pace of community compensation. The building passed through probate court in 2018 and has since changed hands multiple times, so it is now unclear whether there are any low-income residents left to benefit from upgrades.

Benefits yet to be measured

On the brighter side, environmentalists have pointed to the expansion and connection of bicycle trails and bird migration corridors as long-term benefits of the Gordie Howe bridge.

On the Canadian side, the bridge construction falls largely outside of Windsor’s residential neighborhoods, so it caused less disruption. As part of the project,bike lanes, enhanced landscaping, and gathering spaces were added to an approach road called Sandwich Street.

Cross-border tourism spurred on by a proposed system of greenways called the “Great Lakes Way” may provide new opportunities for people and money to flow across the Detroit River, improving the quality of life for communities that remain.

But if the trade war between the Trump administration and Canada continues, observers may question whether the bridge is a graceful gift of infrastructure to two nations or one of the world’s longest and skinniest white elephants.

Trump isn’t cutting Pell Grants, after all − but other changes could complicate financial aid for some students

As an education researcher who has studied the economic returns of higher education, I know that college degrees remain cost-effective investments for most students.

But college tuition has risen at roughly twice the rate of inflation during the past two decades, and federal student debt climbed 500% to US$1.6 trillion during that same period.

The Biden administration sought to address this problem with plans that accelerated student loan forgiveness for lower-income borrowers with small balances, allowing debt cancellation after 10 years of repayment, instead of 20 or 25.

However, the courts blocked those efforts, and the Trump administration has taken a sharply different approach.

Guided by evidence that higher borrowing limits contribute to tuition increases, the tax breaks and spending cuts bill that President Donald Trump signed into law in July 2025 brings changes to the federal financial aid system that prospective higher education students should understand.

The Pell Grant – a need-based higher education grant from the U.S. Department of Education that, unlike a loan, does not need to be repaid – lies at the heart of the federal financial aid system.

While the Trump administration is slightly expanding people’s eligibility for Pell Grants, the new policies also aim to reduce the national student loan spiral by reducing limits on how much some students can borrow for their educations.

Rising college costs and government involvement

The average annual cost of tuition, fees, room and board for a student at a four-year college in the U.S. in the 2022-23 school year was $30,884, according to the latest available Department of Education data.

But the cost of tuition alone varies dramatically between in-state rates for public colleges, which receive state funding, and private nonprofit colleges, which do not.

While the average annual tuition was $9,750 per year for in-state students at public four-year colleges in 2022-23, it reached $38,421 at private nonprofit colleges, even if a student lived at home and did not pay for room and board.

These prices are roughly two to 200 times those of 42 other countries across six continents that have high-quality education data – not including seven countries, including Sweden and Saudi Arabia, that essentially have free tuition.

While many countries around the world subsidize tuition directly, the U.S. government focuses assistance toward individual students based on their financial need.

It does this through a combination of federal grants, loans and subsidies for campus jobs, all administered by the Department of Education.

In 2019-20, about 40% of the nation’s 17 million undergraduates received federal grants – mostly Pell Grants, according to the latest federal data.

Meanwhile, 34% of undergraduates and 39% of the country’s 3 million graduate students received federal loans during this same time period.

Roughly 5% of undergraduates received subsidized on-campus jobs through federal work study in the 2019-20 school year.

Changes ahead for Pell Grants

The U.S. government first awarded Pell Grants to students in 1973. They are designed to make college affordable for families, as determined by their income, family size and savings.

Historically, Pell Grants have focused just on undergraduates.

In 2022-23, about 75% of Pell funds went to students from families earning less than $40,000 per year.

Still, a family of four earning as much as $92,000 a year in 2024 would also qualify for a small Pell Grant in some circumstances.

A version of the Trump administration’s budget proposal for October 2025 through September 2026 called for reducing the maximum federal Pell Grant award to $5,710 a year from $7,395.

This caused some observers to worry that the Trump administration would try to scale back federal Pell Grants, which offer $740 to $7,395 per year to students in the 2025-26 school year.

Instead, the budget bill shores up overall Pell Grant funding and holds grant amounts level with those of previous years. It also creates a new type of Pell Grant to support workers seeking short-term retraining in a particular industry.

The budget bill also introduces another new grant called the Workforce Pell Grant. Starting July 1, 2026, this program will make small Pell Grants available for students pursuing career training programs of eight to 15 weeks toward recognized credentials in “in-demand industry sectors or occupations,” even if students already have bachelor’s degrees.

Controversially, a new House of Representatives appropriations bill proposes to rename the Workforce Pell Grants as
Trump Grants.”

But whether or not Congress approves the renaming, the grants will for the first time make Pell funds available to people who need short-term training to stay current in the labor market.

This is particularly important as long-term unemployment rises among the college-educated, driven by federal layoffs as well as the growth of artificial intelligence.

The role played by federal student loans

Despite some of their advantages, Pell Grants cover only about a quarter of the total cost of college attendance. As a result, 83% of Pell Grant recipients also receive other forms of aid – mostly through federal direct loans, which must be repaid.

The average undergraduate direct loan borrower graduated with about $26,000 in federal debt in 2019-20.

Assuming the 6.08% interest rate on federal loans at that time, it would have cost a graduate $290 a month to repay the loans under the standard 10-year payment plan.

Even so, about 10% of student loan borrowers default, meaning they stop paying on their loans entirely.

Loan default rates are higher among students who attended less-selective colleges and those who did not finish their degrees.

Under existing rules that are not changing under the Trump administration, undergraduates will still be able to borrow up to roughly $10,000 per year in federal direct loans, depending on how far along they are in school.

Graduate students, meanwhile, will still be able to borrow up to $20,500 per year.

New limits for part-time and graduate students

One important change following the Trump budget bill’s passage is that the Department of Education will pro-rate, or reduce, Pell Grant limits for students enrolled part time.

This means tuition at some higher-priced colleges may become unaffordable for part-time students.

This change will force some students to choose between enrolling part time in a low-tuition program or full time in a higher-tuition program.

The other change to federal borrowing limits pertains to graduate students.

The budget bill lowers the lifetime borrowing limit for graduate study from $138,500 to $100,000.

For students pursuing professional degrees such as law and medicine, the limit rises to $200,000.

But the law does away with a program for graduate students called PLUS Loans that now serves about 11% of graduate students, including about 40% of students seeking professional doctorates.

These changes may make it more expensive for graduate students to receive a degree, which could steer them toward lower-priced programs.

The effect for prospective students

As prospective students weigh their options, they should remember that most facets of federal financial aid remain unchanged.

Key changes aim at limiting high debt levels, specifically for part-time and graduate students and those attending high-tuition colleges when lower-priced institutions are readily available.

These changes may reroute some students from private to in-state colleges and from part-time to full-time study. Faced with increased price competition, some colleges may feel pressure to scale back costs through cuts to programs, services and amenities. For prospective students, such moves could reduce colleges’ luxuries but improve their affordability in the long run.

Blood, bruises and belief: how England’s women’s rugby team embody physical and mental endurance

As women’s sport surges on the global stage, hosts England have lit up the Women’s Rugby World Cup. But the tackles, speed and power fans see on the field are only part of the story. What we don’t see is what it takes – both physically and psychologically – to wear England’s emblem, the Red Rose.

The psychology of rugby shapes every performance. Behind the scenes lie early mornings, lonely and punishing rehab sessions, playing through pain, brutal setbacks, private doubts and personal sacrifices.

Before the whistle blows and the crowd roars, players stretch aching muscles, re-tape old injuries and mentally lock in. The changing room becomes a crucible – a place of intense pressure and transformation – where focus sharpens, rituals are repeated and the “game face” goes on.

That game face is more than a stare. It’s the product of years of physical and psychological battles. It’s the mindset that lets an athlete walk into the arena with purpose and conviction, no matter what pain or setbacks they’ve endured.

Consider Emily Scarratt, one of England’s most celebrated players. In 2023 a surgeon advised her to retire after a complex neck injury threatened her career. Opting for an artificial disc replacement near her windpipe was risky – any operation that close to the airway and spinal cord carries the danger of nerve damage or breathing complications – and career-defining because the operation’s success or failure would determine whether she could ever play again.

Her February 2024 return wasn’t just about regaining fitness. It was also about showing the mental steel that “game face” represents, blocking out fear and doubt to perform at the sport’s highest level. At 35, she became the first England player to feature in five Rugby World Cups.

Abi Burton’s comeback is equally astonishing. Just three years ago she was diagnosed with autoimmune encephalitis – a rare condition in which the immune system attacks the brain, causing inflammation and severe neurological symptoms – and placed in a medically induced coma. She woke four weeks later unable to walk, talk, read or write and more than 19 kg lighter. After years of rehabilitation, she made her World Cup debut against Samoa in 2025.

Rosie Galligan’s road back was just as brutal. She nearly lost her legs to meningitis in 2019, then fractured an ankle in early 2020, which sidelined her for over a year. Told by medical specialists and coaches more than once that she might never play again, she fought back to the delayed 2022 World Cup and is now a standout player for 2025.

These headline comebacks highlight something the public rarely sees: the daily grind of resilience. Managing concussions and torn ligaments, coping with the psychological toll of repeated setbacks; just staying in the game takes an immense toll and can lead to player burnout without strong support. Ellie Kildunne, ruled out of the quarter-final with head-injury symptoms, has spoken openly about the mental strength needed to survive the toughest moments, calling the internal battles “the hardest to win”.

So, while England may look clinical and composed on the pitch, every performance requires extraordinary emotional and mental strength. And the players are not doing it alone. Behind every recovery and every small gain is a network of coaches, physiotherapists, psychologists, doctors and support staff working to keep the foundations solid.

None of this happens by accident. It’s the result of years of sustained investment in the women’s game: not just in players, but in the infrastructure around them. Since 2009, nearly £50 million in National Lottery funding has gone into girls’ and women’s rugby.

The Impact 25 legacy programme – World Rugby’s initiative to grow the women’s game before, during and long after the 2025 tournament – is injecting a further £12 million to expand grassroots pathways: community-level coaching, clubs and player-development routes that help girls progress from school or local teams into elite rugby across England and the home nations.

Elsewhere the contrast is stark. Teams such as Samoa have had to fundraise just to get players on the pitch: a sharp reminder of the global inequalities that persist in women’s sport. While England can rotate two professional squads, other national teams are simply trying to cover basic costs.

England’s story shows what’s possible when talent is matched with belief and when belief is backed with resources and support. England’s success hasn’t come easy: it’s the product of years of grit, resilience and bold investment. If women’s rugby is to grow globally, England’s blueprint may be a powerful place to start.

A contemporary history of Britain’s far right – and how it helps explain why so many people went to the Unite the Kingdom rally in London

Source: The Conversation – UK – By Aaron Edwards, Honorary Research Fellow, University of Leicester

The recent “Unite the Kingdom” rally in London shows how easy it is for the radical right to mobilise a mass protest by repackaging a perennial issue as a moral panic. It did so by fusing together fears of migration and crime with a rising distrust in government.

There were calls for “remigration”, mass deportation and even the dissolution of parliament as well as violent clashes with police. There was also a level of confusion among some of the thousands of people who attended as to whether they were protesting for freedom of speech or lending their voices to a racist cause.

Although the scale of the demonstration was surprising to many, far-right activism has a long history in the UK.

In the contemporary era, it dates back to the British Union of Fascists in the 1930s. But it was the increase in immigration in the 1950s – the Windrush era – that saw a new generation of far-right activists emerge.

In the years that followed, Britain’s far right switched its focus from antisemitism to opposing migration from the country’s colonies and former colonies. This was captured best, perhaps, in the infamous “rivers of blood” speech delivered by Conservative MP Enoch Powell in 1968.

By the 1980s, the British National Party (BNP) emerged, growing to make considerable electoral headway in the 1990s and 2000s before its base ultimately crumbled due to its toxic image.

In its wake, the far-right morphed into street protest movements like the English Defence League (EDL) and the Football Lads Alliance. Extremist “direct action” groups like Combat-18, a neo-Nazi group that grew out of the BNP in the 1990s, would also be replaced by National Action and the Patriotic Alternative.

These violent fringe groups were banned but others have replaced them and grown in influence. They include the cultural nationalist movement coalescing around former EDL leader Stephen Yaxley-Lennon, known popularly as “Tommy Robinson” – the man behind the Unite the Kingdom rally in London.

Extremism expert Chris Allen has noted how the re-emergence of radical right protest activism had its medium-term origins in the 2016 Brexit referendum. This relates to how some pro-Leave politicians promoted issues that had “a clear resonance with the traditional and contemporary radical-right” – such as border security and sovereignty.

Rightwing extremist activity ranged from the murder of Jo Cox MP a week prior to the Brexit referendum to street agitation whipped up by other fringe far-right groups, like Britain First. According to the Tony Blair Institute for Global Change, these groups attempted to “dominate the narrative on key political and social issues, including immigration, Brexit and Islam”.

The anxiety around immigration had already found its way into mainstream political discourse on the doorsteps during the 2015 general election. Narrative tropes about “taking back control of our borders” became part of everyday political rhetoric. In the aftermath of the election of that year, prime minister David Cameron made cracking down on immigration a priority.

As antagonism towards the EU began to recede in the years after the Brexit referendum, the fear of irregular immigration came much more to the fore. So too did a rise in racism and race-related hate crimes.

Many of these hate crimes happened in the wake of Islamist terror attacks in 2017, though the arrival of the COVID pandemic superseded fears surrounding terrorism. And as the UK re-emerged from COVID lockdowns, little consideration was given by the British state to the growing security challenge posed by irregular immigration.

It was in this context that a tipping point was reached. In July 2024, after the murder of three children in Southport, radical-right social media influencers and other bad actors stirred up riots across 27 towns and cities in England and Northern Ireland. Thousands of people were radicalised by the language of a moral panic, played out in the new domain of social media.

Illegal immigration as a form of moral panic

Sociologist Stanley Cohen coined the term “moral panic” in his important 1972 book Folk Devils and Moral Panics. He described how a “condition, episode, person or group…emerges to become defined as a threat to societal values and interests” and is then presented in a stereotyped fashion by the media.

Perhaps the most famous of these moral panics came in the immediate aftermath of a huge 1964 brawl in the seaside town of Clacton between mods and rockers, two rival youth counter-cultures. Cohen’s argument was that the reaction ended up being wildly disproportionate to the severity of the original incident. Local authorities in towns and cities as far away as Belfast were forced to issue statements reassuring the public they did not have a “hooligan problem”.

In 2002, Cohen demonstrated how the same phenomenon was being playing out in relation to immigration. He remarked that the once morally untouchable category of political refugee was becoming “deconstructed”. In Cohen’s opinion, British governments were starting from a broad consensus that “we must keep out as many refugee-type foreigners as possible” and that “these people always lie to get themselves accepted”. To be accepted, they must be “eligible” and “credible”.

It was in the ensuing decades, one could argue, that moral panics centring on the triumvirate of migration, crime and security began to emerge in Germany, Italy and the UK.

The British tabloid media led this new moral panic, greatly aided by two intersecting and overlapping empirical realities: the rising tide of concern over increasing immigration in the UK – and Europe more broadly – and the repackaging of ethnically competitive politics as a new form of everyday reality. In the far-right worldview, politics is about the zero-sum nature of power relations between different ethnic groups.

Old tropes, new moral panics

What we are now seeing is a new politicisation of a long-running issue. Humanitarian responses to asylum seekers have been replaced with the trappings of a moral panic about irregular immigration.

Moral panics do not, as Cohen reminds us, necessarily reflect the reality of the situation, only the anxiety of those who spread it. That does not mean there are no serious concerns underpinning these issues, only that they have been magnified and, importantly, amplified by the far-right’s sophisticated embrace of new technology. This situation is, at its core, a crisis in confidence between a section of the population and the government.

As we move towards towards the next UK election, further disillusionment is more likely to manifest itself in increased electoral support for parties like Reform UK and Advance UK, particularly if they continue to play to hardline supporters. In a recent YouGov survey, 44% of those surveyed said Reform’s immigration policy, which includes mass deportation was about right or not tough enough.

While radical-right demonstrations promoting the totemic policy of “remigration” remain largely peaceful, there is a danger that the mainstreaming of such extremist rhetoric will only serve as a driver towards radicalisation for a new generation of far-right extremists.

Why slugs are so hard to control – and how scientists are working to keep them in check

Source: The Conversation – UK – By Sergei Petrovskii, Professor of Applied Mathematics , University of Leicester

Most people aren’t keen on sharing their salad with a slug. Lisa-S/Shutterstock

Almost everyone who has a garden knows what a nuisance slugs can be. They are also one of the most destructive crop pests in the UK. Studies show that yields of many major crops, such as wheat, are severely reduced by their feeding.

But recent research into slug movements may help farmers with their slug prevention strategies

A 2014 report from the Agriculture and Horticulture Development Board estimated that slugs would cost the industry up to £100 million per year in the UK alone, in the absence of effective control. And contamination makes produce undesirable to consumers – nobody wants to find a slug in their lettuce.

Making a living by growing food is already difficult because of labour shortages and rising costs, climate change and other challenges. The slug problem has been in the spotlight for a long time, but development of affordable and reliable solutions has proven to be difficult.

Good pesticides are available, but several aspects of slug behaviour means they can be hit and miss. For example, most pesticides target only slugs that are active on or very close to the surface. However, a large proportion of the slug population can be found at different depths in the soil. This is because they move up and down the soil depending on the weather, soil characteristics and several other factors.

During harsh weather they can become less active, remaining deeper in the soil or hiding themselves in concealed or hard-to-reach places under stones or in dense vegetation such as tussocky grass. This gives a false impression they have disappeared, but they can re-emerge fast and in large numbers once the weather improves.

Some of the chemical pesticides (such as metaldehyde) that work well on slugs are banned under UK legislation due to concerns about their damaging effect on the environment, in particular on rivers and lakes. Biological products, for example some nematodes, seem to work well but farmers consider them too expensive to be commercially viable. Nematodes are microscopic creatures also known as roundworms and some species can infect and kill molluscs such as slugs. They are a good option for gardeners, however, who normally need to apply a lot less because they have a smaller space to protect.

Tracking slug groups

One possible solution to the problem lies in studies showing that the distribution of slugs over an arable field is uneven. Previous studies of slugs in major crops including wheat and oilseed rape, as well as cover crops and fields left fallow, noticed large numbers of slugs tend to congregate together in patches interspersed with areas where slug numbers are sparse. Indeed our 2020 paper showed this was true in all the arable fields we studied.

Spatial distributions of animals in their natural environment are rarely uniform. You might expect animals to congregate in areas with a higher density of food. But in many cases animals form “patches” even in environments where features like food are evenly spread out. Researchers are unsure why this is.

If we can predict where those patches with the high density of the slugs will occur, farmers could concentrate pesticides and nematodes in those areas, which would be a lot more affordable and better for the environment. A separate 2020 study that two of us (Keith and Natalia) worked on found this could help farmers reduce pesticide use by about 50%.

However, this would only be feasible if the location of patches of high slug density doesn’t change much. Until recently information about slug patch formation and stability was scarce. Our 2022 study, however, reported stable slug patches formed in all the crops that we investigated. And these patches always formed in the same places throughout the growing season.

As part of a previous research project we put radio-tags on slugs to track their movements in the field. That paper found slugs exhibited collective behaviour which means they move differently when they move in a group. The changes are subtle. Their average speed and basic zigzagging of their movement paths doesn’t change much. Although, looking in detail, they make steeper turns when they “zig” and “zag” and individual slugs develop a slight bias in their direction of turn. They also tend to rest more when they’re together.

We used the data from the radio-tags to make a digital model of the slug populations we studied. This allowed us to look into factors that would be difficult or even impossible to investigate in the field.

Whether you like slugs or loathe them, we need to understand them if we want to help farmers grow our food in the future.

The Ganges River is drying faster than ever – here’s what it means for the region and the world

The Ganges, a lifeline for hundreds of millions across South Asia, is drying at a rate scientists say is unprecedented in recorded history. Climate change, shifting monsoons, relentless extraction and damming are pushing the mighty river towards collapse, with consequences for food, water and livelihoods across the region.

For centuries, the Ganges and its tributaries have sustained one of the world’s most densely populated regions. Stretching from the Himalayas to the Bay of Bengal, the whole river basin supports over 650 million people, a quarter of India’s freshwater, and much of its food and economic value. Yet new research reveals the river’s decline is accelerating beyond anything seen in recorded history.

In recent decades, scientists have documented alarming transformations across many of the world’s big rivers, but the Ganges stands apart for its speed and scale.

In a new study, scientists reconstructed streamflow records going back 1,300 years to show that the basin has faced its worst droughts over the period in just the last few decades. And those droughts are well outside the range of natural climate variability.

Stretches of river that once supported year-round navigation are now impassable in summer. Large boats that once travelled the Ganges from Bengal and Bihar through Varanasi and Allahabad now run aground where water once flowed freely. Canals that used to irrigate fields for weeks longer a generation ago now dry up early. Even some wells that protected families for decades are yielding little more than a trickle.

Global climate models have failed to predict the severity of this drying, pointing to something deeply unsettling: human and environmental pressures are combining in ways we don’t yet understand.

Water has been diverted into irrigation canals, groundwater has been pumped for agriculture, and industries have proliferated along the river’s banks. More than a thousand dams and barrages have radically altered the river itself. And as the world warms, the monsoon which feeds the Ganges has grown increasingly erratic. The result is a river system increasingly unable to replenish itself.

Melting glaciers, vanishing rivers

At the river’s source high in the Himalayas, the Gangotri glacier has retreated nearly a kilometer in just two decades. The pattern is repeating across the world’s largest mountain range, as rising temperatures are melting glaciers faster than ever.

Initially, this brings sudden floods from glacial lakes. In the long-run, it means far less water flowing downstream during the dry season.

These glaciers are often termed the “water towers of Asia”. But as those towers shrink, the summer flow of water in the Ganges and its tributaries is dwindling too.

Humans are making things worse

The reckless extraction of groundwater is aggravating the situation. The Ganges-Brahmaputra basin is one of the most rapidly depleting aquifers in the world, with water levels falling by 15–20 millimeters each year. Much of this groundwater is already contaminated with arsenic and fluoride, threatening both human health and agriculture.

The role of human engineering cannot be ignored either. Projects like the Farakka Barrage in India have reduced dry-season flows into Bangladesh, making the land saltier and threatening the Sundarbans, the world’s largest mangrove forest. Decisions to prioritise short-term economic gains have undermined the river’s ecological health.

Across northern Bangladesh and West Bengal, smaller rivers are already drying up in the summer, leaving communities without water for crops or livestock. The disappearance of these smaller tributaries is a harbinger of what may happen on a larger scale if the Ganges itself continues its downward spiral. If nothing changes, experts warn that millions of people across the basin could face severe food shortages within the next few decades.

Saving the Ganges

The need for urgent, coordinated action cannot be overstated. Piecemeal solutions will not be enough. It’s time for a comprehensive rethinking of how the river is managed.

That will mean reducing unsustainable extraction of groundwater so supplies can recharge. It will mean environmental flow requirements to keep enough water in the river for people and ecosystems. And it will require improved climate models that integrate human pressures (irrigation and damming, for example) with monsoon variability to guide water policy.

Transboundary cooperation is also a must. India, Bangladesh and Nepal must do better at sharing data, managing dams, and planning for climate change. International funding and political agreements must treat rivers like the Ganges as global priorities. Above all, governance must be inclusive, so local voices shape river restoration efforts alongside scientists and policymakers.

The Ganges is more than a river. It is a lifeline, a sacred symbol, and a cornerstone of South Asian civilisation. But it is drying faster than ever before, and the consequences of inaction are unthinkable. The time for warnings has passed. We must act now to ensure the Ganges continues to flow – not just for us, but for generations to come.

The Biggest Loser: how an aggressive entertainment culture normalised body-shaming

Source: The Conversation – UK – By Freya Gowrley, Lecturer in History of Art and Liberal Arts, University of Bristol

The Netflix documentary Fit for TV: The Reality of the Biggest Loser raises questions around the ethics of one the most popular US reallity TV series of the 2000s. From claims about the cruel treatment of its contestants and its callous endorsement of “fatphobic” narratives, the series sits at odds with feelings around body image and weight in a post body-positivity age.

Recently in the UK reality television shows such as Love Island have been under the spotlight for alleged bullying and misogynistic behaviour. This perhaps shows that a more sustained reckoning is on the horizon for programmes dealing with our bodies, and their long-term effects on the collective psyche.

The idea for The Biggest Loser came to its executive producer David Broome when he spotted a sign posted by an “obese person seeking a trainer” to help them get into shape. The show would eventually see contestants and trainers battling to see who could lose the most body weight through the show’s extreme methods, ultimately winning a prize of US$250,000 (£185,000).

This was a significant amount of money, especially for the time, but the real prize was supposedly the discipline and freedom gained through the process of radical body transformation. As such, the show is rooted in narratives of hard work, determination and ultimately the American dream – you can be anything you want, as long as you work hard enough.

Baiting and exploitation

Despite these seemingly wholesome aims, the documentary points out that the tone of the show was initially unclear. Indeed, its title seems to invite the ridicule of its participants. The first few seasons were presented by a comedian and stacked with challenges seemingly designed to humiliate contestants.

In one episode, the “losers” were asked to build a tower of food with their teeth. In another, they were asked to survive temptation challenges – they could eat as much as they wanted for the chance to see a loved one or go home, but they would still be weighed in at the end of the week.

While these challenges are justified in the documentary by producers as realistic scenarios replicating real-life temptations, commentators such as fat-acceptance activist Aubrey Gordon noted that these tests were based around the presumption that “fat people cannot be trusted around food”. Revelling in the spectacle of failure, such challenges encouraged moralising judgments.

In the temptation challenges, the visual pleasure of excess was clear. Key to such challenges was transforming weight loss into drama – a spectacle people would watch.

Extravagant display was necessary as the show revolved around the potentially slow process of losing weight. Indeed, while diet has been shown to be key for those hoping to reduce their body mass, a programme of extreme exercise was devised. Contestants, often on as little as 800 calories per day, were shown sweating, vomiting and collapsing, cameras shaking to convey the heft of their bodies.

As the seasons progressed, the weight of participants starting The Biggest Loser “journey” went up and, arguably, their ability to work out safely went down, much to the dismay of the show’s medical adviser, Dr Robert Huizenga.

On both the original show and the documentary, Huizenga is presented constantly at odds with trainers Bob Harper and Jillian Michaels, whose methods he challenged. In his obvious concern for the contestants, he became a voice of reason in a show that seemed focused on the entertainment value of those taking part.

The magic of TV transformation

The 2000s ushered in a new era of exposure – an abundant culture of images and television shows celebrating the glamorous lives of celebrities. But this was not limited to the the rich and the famous.

Shows like Pop Idol plucked everyday Joes from obscurity and placed them in the spotlight. These shows glamourised the self-help mentality of the American dream. Hard work, self-control and more than a dash of “natural” talent and beauty were all one needed to be propelled into relative superstardom.

Like rough stones turned into shiny gems, members of the public became top models, popstars and even Dallas Cowgirls as if at the click of a finger. This was a process of transformation, often centred on the visual. It was only logical that this be extended to the most extreme kind of bodily transformation that could be recorded. The message in all of these shows was clear: with extreme hard work and determination you too could achieve the body, the celebrity, the popularity or whatever you deserved.

The Biggest Loser was far from the only series promoting negative stereotypes around people’s bodies on TV at the time. As the virality of body-shaming clips from shows like America’s Next Top Model and 10 Years Younger shows, this was an all-encompassing entertainment culture that villainised gaining even a few pounds.

Today, weight loss is omnipresent once more thanks to the prominence of drugs like Ozempic. In the last two years, we have gone from a broad culture of bodily acceptance to one that seeks to achieve perfection. Celebrities are thinner and look younger than ever, and the abundance of these transformational narratives on social media suggests that we should all aspire to follow suit.

The changing reception of The Biggest Loser – once a very popular programme – revealed in Netflix’s documentary not only shows how influential the media can be in how we see our own bodies, but also reinforces how fickle bodily trends can be.

We can’t know how long it will be until we are told once more to embrace our curves and wrinkles – but you can be sure that it will be visual media that will drive the change.

‘Your countries are going to hell’: Trump’s UN speech explained by an expert

Source: The Conversation – UK – By David Curran, Research Fellow: Peacekeeping and Peacebuilding, Coventry University

The assembled United Nations dignitaries gave Donald Trump 13 seconds of applause as he approached the podium for his address to the 80th anniversary general debate on September 23. They clapped for 20 seconds when he finished speaking.

In between, having been asked to confine his remarks to 15 minutes (like all other speakers), the US president gave the room a lengthy address that lasted 57 minutes. It veered from the many shortcomings of the previous US administrations, to why UN migration policies were ruining the world, to the climate change “con job”, to a warning to the assembled leaders that “your countries are going to hell”.

At points in between, Trump congratulated himself, for turning the US into the “hottest country anywhere in the world”, for repelling a “colossal invasion” of migrants at America’s southern border and for ending seven wars – for which he repeated his line that he should have been given the Nobel peace prize.

He also savaged the UN, which he said “did not even try to help in any” of the conflicts. “The UN is such tremendous potential. I’ve always said it. It has such tremendous, tremendous potential, but it’s not even coming close to living up to that potential. For the most part, at least for now, all they seem to do is write a really strongly worded letter and then never follow that letter up.” He added: “Empty words don’t solve war.”

Questioning whether the UN could play a productive role, Trump offered “the hand of American leadership and friendship to any nation in this assembly that is willing to join us in forging a safer, more prosperous world”. In other words, UN-led multilateralism is out, to be replaced, perhaps, by a series of bilateral relationships dominated by the US.

Eight decades after its founding in the wake of the second world war, it is not a good time for the UN. It is currently mired in a budget crisis: US$2.4 billion (£1.77 billion) in unpaid dues from member states against an overall budget of US$3.5 billion for 2025. Of this, the US owes the most, about US$1.5 billion.

The Trump administration is applying a much-reduced budget that includes zero funding for UN peacekeeping operations. This decision has been made despite the fact that the US has an obligation to pay at least one-quarter of the UN’s peacekeeping costs. It has also paused most other funding to the body.

Trump’s speech to the United Nations in full.

Trump’s speech did not shy away from other issues of critical importance. He highlighted the need to “stop the war” in Gaza and negotiate peace. He also chastised Russia for its invasion of Ukraine. But his views on these conflicts were largely aimed at individual states as opposed to the UN – and multilateralism – in general.

When it came to Gaza, he was critical of the states that “unilaterally” recognised Palestinian statehood. Talking about Ukraine, Trump criticised European states for not cutting off purchases of Russian energy and energy products. The UN, and its efforts in addressing these catastrophic situations, was not mentioned.

Migration and climate

But Trump was most savage when it came to migration. He opened his section on migration by stating that “your countries are being ruined”, stating: “The United Nations is funding an assault on western countries and their borders.” Claiming that the UN provides cash assistance towards migrants journeying to the US, Trump then stated: “The UN is supposed to stop invasions, not create them.”

The rest of his discussion on migration was aimed at Europe. Within that he offered unsubstantiated claims about London – with whose mayor, Sadiq Khan, he has a longstanding disagreement: “Now they want to go to sharia law” he said.

His language here will (rightly) cause considerable concern for many. It may reflect his belief in the role of sovereign borders, particularly in the US. But the attachment – in particular with regards to European states – of the idea of sovereignty to a way of life that is somehow endangered by migration is one which could embolden anti-migrant sentiment on a global level.

Trump’s views on climate change will also grab headlines. Interestingly though, given his other criticisms of the UN, while he called climate science and the idea of man-made global warming “the greatest con job ever perpetrated on the world”, his scorn wasn’t particularly aimed at the UN.

Granted, the UN has been in the driving seat for many of the steps taken in attempting to tackle the climate crisis – so by implication, the UN was in the US president’s sights. But he instead he took the opportunity to direct his slurs towards China which – he said – builds wind turbines “and they send them all over the world but they barely use them”.

So what can be taken from this? It may not have been a worst-case scenario for those who support international cooperation. He didn’t explicitly pull the US out of any other UN programmes.

But there’s very little to take reassurance from a multilateral perspective when viewing Trump’s 57 minutes at the lectern. In his view, the UN is not up to speed with attempts to build peace, it doesn’t function properly, it’s secondary to bilateral efforts, and – when it comes to the US – it has supported an “invasion” by migrants.

And, reading between the lines, Trump’s perspectives on sovereignty, climate change and migration may embolden other political leaders who want to push similar agendas. It has the danger of going beyond rhetoric.

The US president’s disdain for multilateralism and the UN system may mean other members reprioritise their budgets, cutting funding still further. This would further fracture a UN system which is already seriously under pressure.

What is leucovorin, the drug the Trump administration says can treat autism?

Source: The Conversation – Global Perspectives – By Nial Wheate, Professor, School of Natural Sciences, Macquarie University

The US government has announced controversial guidance on the prevention and treatment of autism in children.

New health recommendations aim to discourage pregnant women from taking the painkiller paracetamol – also known as acetaminophen and by the brand name Tylenol – to prevent autism.

The recommendations also include using the drug leucovorin to treat speech-related difficulties that children with autism sometimes experience.

So what is leucovorin and what does the science say about its ability to treat autism?

What is leucovorin?

Leucovorin is a form of folic acid, a B vitamin our bodies usually get from foods such as legumes, citrus fruits and fortified grains.

The medication is most often used in cancer treatment. It’s typically used alongside the chemotherapy drug fluorouracil, a cancer treatment that stops cancer cells from making DNA and dividing. Leucovorin enhances the effects of fluorouracil.

Leucovorin is also used to reduce the toxic side effects of methotrexate, another chemotherapy drug.

Methotrexate works by blocking the body’s use of folate, which healthy cells need to make DNA. Leucovorin provides an active form of folate that healthy cells can use to make DNA, thereby “rescuing” them while methotrexate continues to target cancer cells.

Because methotrexate is also used to treat the skin condition psoriasis, leucovorin can also be used as a rescue agent during treatment for this autoimmune condition.

Why is folate important?

Because folate is essential for making DNA and other genetic material, which cells need to grow and repair properly, it’s especially important during pregnancy.

This is because insufficient folate is linked to the development of spina bifida, a condition where a baby’s spine does not develop correctly. For this reason, women are advised to take folic acid supplements before conception and during the early months of pregnancy.

Folate is also important for supporting the production of red blood cells and overall brain function.

Why is it being considered to treat autism?

The recommendation to use leucovorin to treat autism seems to stem from a theory that low levels of folate in the brain can lead to a condition called cerebral folate deficiency.

Children with cerebral folate deficiency don’t usually display symptoms for the first two years. Then they show signs of speech difficulties, seizures and intellectual disability.

As the signs of autism are similar and it usually presents at around the same age, some people have proposed a link between cerebral folate deficiency and autism.

What does the evidence say?

So can giving children folate, in the form of leucovorin, help them to function better with autism? The evidence says maybe yes, and here’s what we know so far.

A review of the evidence in 2021 analysed the results of 21 studies that used leucovorin for autism or cerebral folate deficiency. Children who took the drug generally had improved autism symptoms. But the authors also said more studies were needed to confirm the findings.

Since then, a small 2024 study involved about 80 children aged two to ten years with autism. Half took a daily maximum dose of 50mg of folinic acid (similar to leucovorin), the other half took a placebo. Children given folinic acid showed more pronounced improvement when compared with those who took the placebo.

A similar 2025 study examined the same dose of folinic acid given to Chinese children with autism. Those given folinic acid had greater improvement in a type of social skill known as social reciprocity when compared with children given placebo.

While promising, none of these trials are at the level to change medical practice. We’d need further, larger studies before doctors can make a proper recommendation.

Like all drugs, leucovorin has side effects. The most serious or common are severe allergic reactions, seizures and fits, and nausea and vomiting.

In a nutshell

Overall, the latest health recommendations are not yet backed by sufficient evidence.

While the US Food and Drug Administration will now allow doctors to prescribe leucovorin to treat autism symptoms, the Australian government should not change its prescribing guidance.

Support for people with autism should continue to follow evidence-based best practice until the data from clinical trials of leucovorin is more robust.
