The Science Behind Cold Exposure and Weight Loss Wearing an ice vest or taking daily cold showers could help people lose weight, according to researchers. Despite the growing popularity of cold-water swimming and freezing plunges, to date there is minimal data on the health benefits of cold exposure. But a study of 47 adults with obesity or overweight has found that regular exposure to cold temperatures led to fat loss. The Study's Methodology and Findings Researchers at the University of Nottingham and the Leiden University Medical Center (LUMC) in the Netherlands gave half the participants an ice vest and waist wrap to wear for two hours every morning, while continuing their daily lives. The vests and waist wrap were worn on top of a thin T-shirt and contained gel-filled cooling packs that had been kept overnight in the freezer and maintained a temperature of 15C. In six weeks, participants lost 0.9kg (2lb), made up almost entirely of body fat, whereas the control group did not lose any weight and put on 0.6kg (1.3lb) on average. The Impact of Cold Exposure on Metabolism The lead researcher, Dr Mariëtte Boon, of LUMC, said: “This is one of the first studies looking at the impact of cold exposure over a prolonged period of time, involving people with overweight and obesity.” She added: “Vests like this can be worn at home and so cold exposure could be a simple and inexpensive addition to lifestyle strategies for weight loss such as healthy eating and physical activity.” The Potential for Cold Showers as a Weight Loss Tool The researchers, jointly funded by the Dutch Heart Foundation and the British Heart Foundation, are investigating whether other forms of regular cold exposure could reduce obesity, inflammation and prevent heart disease. The authors are conducting a separate study of 34 women in the Netherlands to see if cold showers also promote fat loss. Half of the women will have their shower on the coldest setting for 90 seconds every morning.

The LeadOn Friday the River Thames at Ham will host its first official swimming season as the inaugural designated bathing water in London, joining 12 other newly recognised sites across England.Thames at Ham Designated as London’s First Official Bathing WaterThe stretch of the Thames in south‑west London has been granted bathing water status after campaigners, led by Marlene Lawrence of the Teddington Bluetits, submitted evidence of year‑round swimming activity. Lawrence said, “This is amazing for the river and for the many people who enjoy it.”Nationwide Roll‑out of 13 New Bathing Water SitesEnvironmental Minister Emma Hardy announced that the new designations bring the total to 13 new monitored swimming areas across England. The sites are:Canvey Island foreshore, EssexEast Beach at West Bay, Bridport, DorsetFalcon Meadow, Bungay, SuffolkGranville Parade Beach, Sandgate, KentLittle Shore, Amble, NorthumberlandNew Brighton Beach (east), MerseysideNewton and Noss Creeks, DevonPangbourne Meadow, BerkshireQueen Elizabeth Gardens, Salisbury, WiltshireRiver Dee at Sandy Lane, Chester, CheshireRiver Fowey in Lostwithiel, CornwallRiver Swale in Richmond, YorkshireRiver Thames at Ham and Kingston, Greater LondonEnvironmental and Economic ImplicationsThe new bathing water designations expand monitoring by the Environment Agency, which will conduct weekly sampling and publish results online. Hardy highlighted the benefits: “better monitoring of our waterways, a boost for local tourism and greater confidence for local swimmers.” The move follows years of limited bathing water status, which was previously confined to coastal waters and lakes, and aims to curb sewage discharge, PFAS, and agricultural runoff.Future Outlook for River Clean‑up and MonitoringContinued oversight will involve the regulator working with communities, farmers and water companies. At Ilkley, Yorkshire Water is already investing over £85m in infrastructure to improve water quality after the Wharfe received bathing status five years ago. The Thames designation is expected to drive similar upgrades and reinforce the government’s “generational reform” of the water sector.

The Lead In a remarkable feat of endurance and courage, British-Australian ultramarathon swimmer Andy Donaldson has conquered one of the world's most challenging aquatic courses, setting a new world record in the crocodile-filled waters of Western Australia's Ord River. Donaldson completed the 55km Dam to Dam Challenge in an astonishing 11 hours and 51 minutes, shattering the previous record by over four hours. The Record-Breaking Swim Donaldson's journey began at 5:38 AM in Lake Argyle, where he was greeted by a 2.5-meter freshwater crocodile at the start ramp—a stark reminder of the dangers that lay ahead. The Ord River, home to 5,500 freshwater crocodiles (approximately one croc for every 10 meters of the swim), presented a unique challenge that required both physical prowess and mental fortitude. Despite the intimidating wildlife, Donaldson maintained composure throughout the swim. "Freshwater crocodiles are smaller and more timid than their saltwater counterparts," he explained, "and unlikely to approach humans." His team had conducted thorough research beforehand, ensuring safety protocols were in place to handle any potential threats. The swim wasn't without its difficulties. Donaldson faced searing Kimberley temperatures that reached 34°C, a lack of saltwater reducing his buoyancy, unexpected headwinds, and sections of "dead water" with no current. "Especially when you start to fatigue, your hips drop and your body position isn't as good, so you feel like you're dragging the legs a lot more," he noted. The Record Time Analysis Donaldson's completion time of 11 hours and 51 minutes represents a significant improvement over the previous record set by Simone Blazer in 2024, who completed the swim in 16 hours and 13 minutes. This 4 hour and 22 minute improvement demonstrates Donaldson's exceptional endurance and preparation for the challenge. The swim required maintaining an average pace of approximately 4.65 km/h for nearly 12 hours, a remarkable feat considering the physical challenges and environmental factors. Donaldson's ability to sustain this pace through extreme heat and variable water conditions highlights his elite-level conditioning and mental resilience. The Impact on Extreme Swimming This achievement elevates Donaldson's status in the world of ultramarathon swimming and showcases the growing popularity of extreme aquatic challenges. The Dam to Dam Challenge, while previously completed by Blazer, now has a benchmark time that will inspire future athletes to push their limits. The successful completion of this swim also highlights the importance of proper safety protocols in extreme sports. Donaldson emphasized that "safety comes first" and that they "want to be smart and use these challenges to share positive messages, not negativity and fear." This approach to extreme sports could influence how future aquatic challenges are organized and perceived. Additionally, the media attention surrounding this swim, including the Guardian's coverage and the video documentation of the event, brings greater visibility to the sport of ultramarathon swimming and may attract more participants and sponsors to similar events worldwide. The Future of Extreme Aquatic Challenges With this record-setting swim, Andy Donaldson has established himself as one of the premier ultramarathon swimmers in the world. His achievement on the Ord River may lead to increased interest in similar extreme aquatic challenges, particularly those that combine natural beauty with significant physical obstacles. Looking ahead, we can expect Donaldson to continue pushing boundaries in the sport. His description of the Ord River swim as "the best swim I've ever done" and his expressed passion for swimming in "amazing places all around the world" suggest that he will seek out new challenges and potentially attempt other record-breaking swims in the coming years. The sport of ultramarathon swimming may also see increased innovation in safety equipment and training methods, as athletes attempt to conquer even more challenging courses while minimizing risks. Donaldson's success with his support team's approach to safety could become a model for future extreme swimming events.

The Slow TV Revolution: A Moose Crossing in SwedenOn a crisp early spring afternoon in northern Sweden, the stars of The Great Moose Migration are proving elusive, yet the show has become a global sensation. This three-week, 450-hour continuous livestream from the Västernorrland wilderness has captivated millions, defying the expectation that constant action is required for modern television. The show captures the annual migration of moose across the Ångerman river, a journey they have traversed for 6,000 years, now broadcast live for a worldwide audience seeking an antidote to the fast-paced digital world.Technical Ingenuity in the WildernessThe production is a testament to a 'rugged, maverick spirit' rather than high-budget Hollywood equipment. The team relies on 30 cameras hung discreetly from trees, 42 microphones, and over 15 miles of cabling. To protect the gear from the elements, the crew uses DIY solutions, such as black plastic buckets purchased from hardware stores and wrapped in camouflage netting. A critical lifeline is a fiberoptic broadband cable laid along the riverbed, which has famously been chewed through by mice, requiring frantic repairs by local handymen. Despite the challenges, the setup covers a five-mile stretch of the river, ensuring no moment of the migration is missed.From Zero to Millions: The Pandemic CatalystThe show's explosive growth can be attributed to a perfect storm of timing and nature. Season two coincided with the first Covid-19 lockdowns, providing a captive audience desperate for escapism. The data reflects this shift: the highest volume of 'swimmers' registered was 87 in 2023, with concurrent viewership spiking to 20,000 to 87,000 during peak moments. An unofficial Facebook group organically formed, now boasting around 96,000 members, highlighting the community aspect of the viewing experience.Why the Moose Resonates GloballyThe appeal lies in the moose itself, known in Sweden as Skogens konung (the King of the Forest). Professor Göran Ericsson notes that the moose represents the 'accessibility of nature' and is the iconic species of the Nordic region. The show taps into a universal desire for connection with the natural world, proving that even in an era of instant gratification, audiences are willing to invest time in slow, unedited storytelling.Future Horizons: Expanding the MigrationLooking ahead, the producers are focused on increasing the scale and reliability of the broadcast. With the addition of new camera spots, they aim to break the record of 87 moose swimming simultaneously by 2026. The success of The Great Moose Migration suggests that the Slow TV format is not a fleeting trend but a sustainable model for nature programming, promising more seasons of high-fives and hugging for viewers around the world.

The LeadGiant "kraken-like" octopuses that used powerful beaks to crunch through bones of prey were among the most formidable predators of the Cretaceous oceans, according to research. Analysis of dozens of newly identified fossils reveals that some ancient octopus species reached up to 19 metres in length, meaning they would have rivalled – and possibly even preyed upon – apex predators such as mosasaurs and plesiosaurs.The Ancient Octopus DiscoveryDistinct wear patterns on the enormous fossilised beaks, which date back up to 100m years, suggest they would have routinely crushed hard bones and shells. "Our study shows that these were not simply large versions of modern octopuses," said Dr Yasuhiro Iba, a palaeontologist at Hokkaido University and lead author of the research. "They were giant predators at the very top of the Cretaceous marine food web. This changes the view that Cretaceous seas were dominated only by large vertebrate predators."Fossil Evidence and AnalysisUntil now, relatively little has been known about ancient octopuses, whose soft bodies are very rarely preserved as fossils. The study relied on detailed analysis of fossilised beaks, a hard, structure that is the only rigid part of an octopus's body. The team re-examined 15 large fossil beaks that had previously been assigned as vampire squids, but which the latest analysis concludes belonged to a group of ancient octopus relatives known as Nanaimoteuthis. Using digital imaging, the team also uncovered an additional 12 octopus beaks hidden within Cretaceous rocks, dating to 72m to 100m years ago.Size and Predation AnalysisOne species, Nanaimoteuthis haggarti, was found to have a beak larger than that of the modern giant squid, a creature that reaches about 12 metres in length and until now had been regarded the largest known invertebrate. By using the relationship between jaw size and body length in modern finned octopuses, the team estimated that N haggarti was between 7 and 19 metres in total length, which could make it the largest invertebrate on record.Expert PerspectivesDr Thomas Clements, a palaeobiologist at the University of Reading, who was not involved in the research, said: "To see a beak this size is quite amazing, to be honest. It was a massive animal. I certainly wouldn't have wanted to go swimming in the ancient oceans if these things were swimming around." Modern octopuses do not swallow prey whole but use their long, flexible arms to capture and subdue the prey and then dismantle it with their beak. The ancient specimens showed distinct patterns of wear that pointed to a similar predation strategy.Predation Behavior and DietIn the largest individuals, the beaks showed extensive wear, with once sharp features, as seen in small juveniles, becoming blunted and rounded over time, and chips and scratches also visible. Iba said: "It probably used its long arms to seize prey and its powerful lower jaw to crush hard structures such as shells or bones. The strong wear on the jaws indicates frequent processing of hard prey." This would have included bony fish, shelled animals and, possibly, giant marine reptiles such as mosasaurs, which would have been comparable in size.Behavioral SophisticationThe beaks appeared more worn on one side more than the other – evidence of so-called lateralised behavior. This suggests they may have had arm preferences (handedness) for specific tasks, as modern octopuses do, favouring some arms for exploration and others for feeding. Iba said: "This indicates that these animals were not only powerful, but also behaviourally sophisticated predators."Scientific Impact and Future ResearchClements said: "Whenever you see artistic reconstructions, it's always a vertebrate eating a cephalopod. It is quite nice to imagine an octopus eating a large vertebrate for once. As a cephalopod researcher I'm very excited to see invertebrates that may have rivalled vertebrates." The findings are published in the journal Science, opening new avenues for understanding the complexity of ancient marine ecosystems and the role of invertebrates in prehistoric food webs.

A stretch of the River Thames in Henley has been denied official bathing water status, exposing a critical regulatory loophole that is currently stalling environmental cleanup efforts. Campaigners argue that the narrow definition of 'bathers' under current legislation is fundamentally flawed, preventing a town reliant on its river for tourism and sport from accessing the funding and oversight needed to clean its waters.Key DevelopmentsRegulatory Denial: A stretch of the Thames through Henley was rejected for bathing water status because the Environment Agency (Defra) only considers people swimming as 'bathers,' excluding rowers, kayakers, and paddleboarders.Public Health Crisis: Citizen-led testing by Health on the Thames (HoT Water) has recorded E. coli levels averaging 2,922 CFU per 100ml, which is more than 3.2 times the safe limit of 900 CFU per 100ml required for a site to be deemed 'sufficient'.Economic Impact: Local businesses, including boat hire services and the organizers of the annual rowing regatta, report significant losses due to falling entries and reputational damage caused by water quality concerns.Political Pressure: A coalition of businesses, civic leaders, and river users has written to Environment Secretary Emma Reynolds, calling for the expansion of the legal definition of 'bathers' to include all recreational water users.Data & Market ImpactThe data reveals a severe disconnect between the river's usage and its regulatory protection. While the Environment Agency sets a limit of 900 CFU per 100ml for a bathing site to qualify as 'sufficient,' the average levels in Henley are nearly 3.2 times higher. For a site to be rated 'excellent,' levels must drop below 250 CFU per 100ml.This pollution crisis is not merely an environmental issue but a significant economic threat. The cancellation of swimming events and the decline in river-based tourism directly impact the livelihoods of local enterprises. The inability to secure bathing water status means the area lacks the mandatory testing and enforcement powers that would otherwise force water companies to upgrade treatment infrastructure.Why This MattersThis situation highlights a systemic failure in how environmental protection is administered in the UK. The current framework fails to account for the diverse ways people interact with waterways, leaving a vital economic hub vulnerable to pollution without the legal tools to enforce a cleanup.For the town of Henley, the denial of status is a double-edged sword: the poor water quality discourages users, but the lack of users prevents the town from qualifying for the designation that would trigger the necessary cleanup measures. This creates a vicious cycle that endangers public health, particularly for children and those with compromised immune systems who may come into contact with the water during recreational activities.Expert InsightThe core issue lies in the 'catch-22' of the current regulatory system. As noted by Jo Robb of the Henley Mermaids, the system is broken because it requires a critical mass of 'bathers' to qualify for status, yet the water quality is so poor that it actively deters people from entering the water in the first place.This regulatory gap forces local authorities to rely on voluntary citizen science rather than state-mandated enforcement. The call to expand the definition of 'bathers' is not just a semantic change; it is a strategic necessity to align the law with reality. By including participants in rowing, sailing, and kayaking, the legislation would recognize the river's primary users and unlock the statutory powers required to hold polluters accountable.What Happens NextThe government has acknowledged the pressure and stated it is conducting an evidence review to consider expanding the definition of 'bathers.' However, the window for action is narrowing as the upcoming local elections in May loom, with sewage pollution expected to be a central campaign issue.Thames Water's financial struggles and the broader debate on water industry renationalization will likely intensify. If the government fails to act on the evidence review before the elections, the political cost could be high, particularly for the Labour government, which has so far resisted calls for renationalization but is under increasing pressure to deliver on its promises to clean up the nation's rivers.

The Tragic Incident at Ironman TexasA Brazilian fitness influencer has died after getting into difficulty during the swimming portion of an ironman event in Texas. Mara Flavia Souza Araujo was reported as a "lost swimmer" around 7:30 am at the Ironman Texas in Lake Woodlands near Houston on Saturday. Safety crews could not immediately locate Araujo. The 38-year-old's body was discovered around 90 minutes later in 10ft of water by divers. She was pronounced dead on the scene.Montgomery County Sheriff's Department confirmed her identity in a statement to NBC on Monday. "MCSO can confirm that Mara Flavia Souza Araujo, 38, of Brazil died while competing in the Ironman event in The Woodlands on Saturday," the sheriff's department told NBC News. "Preliminary investigations indicate she drowned during the swimming portion of the event."An Experienced Athlete's Final JourneyAraujo was no stranger to the challenges of ironman competitions. Records show she had completed at least nine ironman events since 2018, demonstrating her experience and dedication to the sport. With more than 60,000 followers on Instagram, she had built a significant platform as a fitness influencer, sharing her athletic journey and promoting an active lifestyle.Just days before her death, Araujo had posted a reflective message on Instagram about the importance of making the most out of life. "Enjoy this ride on the bullet train that is life," she wrote in Portuguese. "And even with the speed of the machine blurring the landscape, look out the window – for at any moment, the train will drop you off at the eternal station." The post has since garnered significant attention as friends, followers, and fellow athletes mourn her unexpected passing.Safety Concerns in Endurance SportsThe incident raises questions about safety protocols during mass participation endurance events, particularly the swimming portion which often presents the greatest risk. Ironman events, which consist of a 2.4-mile swim, 112-mile bike ride, and 26.2-mile marathon, attract thousands of participants annually, many of whom are not elite athletes.While organizers have implemented various safety measures including lifeguards, watercraft, and medical personnel along the swim course, the unpredictable nature of open water swimming—where conditions can change rapidly—continues to pose challenges. The fact that Araujo was an experienced athlete who had completed multiple ironman events underscores that even seasoned competitors can face unexpected difficulties in the water.A Legacy Beyond CompetitionBeyond her athletic achievements, Araujo's impact as a fitness influencer continues to resonate with her followers. Her social media profiles, now filled with tributes, reflect the inspiration she provided to others pursuing their fitness goals. Her death serves as a poignant reminder of the risks inherent in pushing physical boundaries, even for those who appear exceptionally capable.Race organizers have expressed their condolences, stating: "We send our deepest sympathies to the family and friends of the athlete and will offer them our support as they go through this very difficult time. Our gratitude goes out to the first responders for their assistance." As the triathlon community processes this loss, discussions about enhanced safety measures and emergency response protocols may gain renewed attention in the coming months.

The Economist as Saviour: A Life in the CrossfireLord Robert Skidelsky, who died aged 86, was not merely a historian but a prophet of economic reality. His passing marks the end of an era for British intellectual life, leaving a void where a rigorous challenge to free-market orthodoxy once stood. Skidelsky’s career was defined by his monumental biography of John Maynard Keynes, a project that consumed two decades of his life.The Return of the Master: Keynesianism in the 21st CenturyThe defining moment of Skidelsky’s later career came on 15 September 2008, with the collapse of Lehman Brothers. This event rendered his decades of research suddenly relevant. While the global establishment was caught unawares by the crisis, Skidelsky felt a duty to "return to the fray."2008 Crisis: The plunge of the global financial system forced policymakers to dust down Keynes's General Theory.2009 Publication: Skidelsky released Keynes: The Return of the Master, validating the need for stimulus over austerity.Policy Shift: Governments briefly embraced stimulus, cutting rates and printing money to stave off a second Great Depression.The Austerity Critique: A Lost Decade for the UK EconomySkidelsky’s most significant impact lies in his prescient critique of the 2010-2015 austerity measures imposed by the Conservative-Liberal Democrat coalition. While he was part of an "embattled minority," his warnings proved prophetic.The immediate post-crisis recovery was halted by premature fiscal tightening. Skidelsky argued that the UK economy has yet to fully recover from the events of 2008, largely due to the failure to embrace Keynesian ideas long enough. His criticism of George Osborne and the subsequent Rachel Reeves budget highlights his enduring belief that the UK is shackled by "mistaken academic orthodoxy."A Legacy of Maverick OrthodoxySkidelsky was a political maverick, moving from Labour to the SDP to the Conservatives before becoming a crossbench peer. His career was characterized by swimming against the tide, whether supporting Jeremy Corbyn or advocating for a negotiated peace in Ukraine.His final work, Keynes for Our Times, due for release next month, suggests that his battle is not over. As the world grapples with economic stagnation and geopolitical instability, Skidelsky’s insistence that economics must serve human well-being rather than abstract growth remains a vital, if unheeded, prescription for the future.

Crystal Palace, once the 'hallowed turf' of British athletics, is on the verge of a major transformation. The stadium, which has hosted iconic athletes like Sir Mo Farah, Dave Bedford, and Steve Backley, had fallen into disrepair but is now set to be revitalized with a £130m redevelopment plan. The London Mayor, Sadiq Khan, announced the plans in May 2023, declaring Crystal Palace a 'national asset.' The proposed redevelopment includes a vastly upgraded 25,000-seat stadium that could open as early as 2030, along with a new 200m running track for community use. The journey to this point has been long and arduous. Jim Powell, a former sprint coach and founder of the Met-Track charity, recalls the despair that had settled over the venue years ago. 'There were trees growing out of the main stand and on the indoor track and no one was doing anything about it,' he says. The formation of the Crystal Palace Sports Partnership in 2014 marked a turning point, with Powell and others fighting to save the venue. 35,000 people signed a petition to reopen the site's swimming pools, which had been closed due to a leak. The partnership's efforts eventually led to the current redevelopment plans, with Morgan Sindell appointed as developers in 2024. The new sports centre will feature a padel centre, basketball courts, football pitches, and a full-size artificial multi-sports pitch. While the project is already fully funded, the search is on for commercial investment to complete the stadium bowl and boost its capacity from 16,000. Powell, who was given an MBE in 2013 for his services to athletics, is ecstatic about the plans. 'This is a historic and much-loved national sporting and community facility, where many UK sporting stars have started their careers and trained, but it needs major investment and refurbishment,' Khan said when the application was submitted. The potential return of big events like the Diamond League to Crystal Palace has Powell hopeful. 'It used to be the hallowed turf or the hallowed tartan,' he reminisces. 'If this new stadium doesn’t give athletics a shot in the arm, nothing will.'
