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 Lead: England's Post-Ashes CrossroadsIn selecting Emilio Gay and James Rew for their Test squad to face New Zealand, England have in one sense been true to their word. The Ashes mea culpa included a promise to give more weight to domestic performances. Both men tick that box. And yet as the team picks up the pieces after the 4-1 defeat in Australia, wounds licked and lessons learned, perhaps the question is whether they are staying true to themselves more broadly – or even, who actually are they these days?The Event Details: McCullum's Coaching Philosophy in FluxAsked about his future as head coach at the end of the Ashes tour, and whether he could change his approach, Brendon McCullum gave a notably qualified answer. "I have a firm conviction in a lot of my methods," McCullum replied. "I'm not against evolution and progress. However, you need to stand for something. Without being ultimately able to steer the ship, maybe there is someone better."Among those methods was having a pared-back support staff. McCullum previously felt there were too many voices in the dressing room and duly whipped out the gardening shears. By the time Australia came around it left just two assistants in Marcus Trescothick and Jeetan Patel and a short-term bowling coach in David Saker.But when McCullum arrives back in the country next week ahead of a three-day camp in the Midlands – training and team-bonding before the first Test at Lord's starts on 4 June – he will walk into a set-up that has swelled by way of numbers.The Staff Expansion: From Minimalist to Maximum SupportAs well as the two assistants, Sarah Taylor will now lead the fielding drills (and no doubt work on fine-tuning Jamie Smith's wicketkeeping given her own excellence here). Mike Yardy, the England Under-19s head coach, and Will Gidman, who works at Durham, have also been seconded for extra support around the place.Troy Cooley will attend the camp, having rejoined the English game over the winter as "National Pace Bowling Lead", while Tim Southee returns as the team's bowling coach; albeit, like Jofra Archer, only once his work at the Indian Premier League is done. From not wanting too many voices, McCullum now has an entire chorus line.There is talk that extra coaching input is at the behest of the captain, Ben Stokes. And if so, it strikes to the heart of some of the tension in Australia. McCullum didn't want players to burn themselves out by over-training, even shoo-ing players out of the nets at times. Stokes, relentless by default, was the one pushing for more.The Performance Evolution: Nutrition and Selection ChangesOn top of all the extra bodies, England are recruiting a "Performance Chef Consultant" for the team, whose role will be to "plan and execute menus that support training adaptation, match performance and recovery". This is in keeping with most elite sporting environments these days. But it also feels very un-McCullum when you consider one of his first moves four years ago was to dispense with the team's nutritionist. Bacon sandwiches were back on the menu in 2022, with players trusted to make the right decisions.Another change this summer is the arrival of Marcus North as selector. It looks a sound acquisition, with Durham's outgoing director of cricket well connected and widely respected in the game. At Chester-le-Street, North is viewed as someone who prefers to give it to players straight but also deals with the human being.North, like Luke Wright before him, is not the chair of selectors however. As the press release confirming his appointment put it, he will "work collaboratively on selection matters" and "contribute to decisions" regarding contracts. So another voice at Rob Key's table – an important one – but not calling the shots per se.The Impact Analysis: Shifting Team IdentityIn the runs this year for Durham, known to the set-up via the Lions, and having made four centuries in Division One last year, Gay is a sound selection as the team's new opener. How he or any new player adjusts to the step up in standard and scrutiny thereafter is always the great unknown.But it is not a huge leap to suggest that before the great slapdown Down Under, England may well have opted for 6ft 7in Ben McKinney, who at 21 is five years younger than his Durham teammate and is considered a terrific prospect. Who knows, they might even have backed Zak Crawley to continue.As a selector himself, albeit on the other side of the world during the first six rounds of the County Championship, McCullum will have had an input. Likewise regarding the expansion of his backroom staff. The question now is how he fits back into an environment where relaxation is meant to make way for more rigour.The Prediction: McCullum's Path ForwardThere is also the subject of results. Four years ago McCullum was hired after an Ashes defeat so harrowing that expectations were low – a period that allowed him to breathe fresh life by taking minds away from outcomes. Players were told to be free, to attack, and not to worry about the consequences. It worked well initially.But this summer, the leadership having survived a rash of missteps in Australia, getting wins on the board against New Zealand and Pakistan feels non-negotiable if this supposed reboot is to have legs. Much may hinge on whether McCullum can adapt, or whether these changes ultimately compromise what he stands for.

Executive Summary of Trump’s Xi Conversation ClaimOn May 15, 2026, former U.S. President Donald Trump announced that he had a direct discussion with Chinese President Xi Jinping regarding a possible arms sale to Taiwan. The statement, delivered without accompanying evidence, has sparked immediate reactions across diplomatic and defense circles.Trump Alleged Direct Talk with Xi on Taiwan Weapons TransferAccording to the former president, the conversation covered:The scope of advanced weaponry that could be supplied to Taiwan.Potential timelines for delivery and training.China’s strategic response to any such transaction.Trump framed the dialogue as a “peace‑keeping” effort, suggesting that transparency between the two leaders could avert escalation.Absence of Concrete Figures Leaves Financial Impact UnclearNo monetary values, contract details, or official approvals were disclosed. Consequently, analysts cannot quantify:Potential revenue for U.S. defense contractors.Budgetary implications for the U.S. Department of Defense.Economic repercussions for Chinese defense exports.The lack of data keeps the claim in the realm of political signaling rather than actionable policy.Potential Ripple Effects on US‑China‑Taiwan Strategic BalanceThe assertion could influence several fronts:Diplomatic*:* Washington may face pressure to clarify its official stance on Taiwan arms sales.Security*:* Regional actors, including Japan and South Korea, might reassess their own defense postures.Domestic Politics*:* Trump’s narrative could be leveraged in upcoming U.S. elections to portray a tougher China policy.Chinese officials have not confirmed or denied the conversation, maintaining a cautious diplomatic tone.What This Claim Could Signal for Future Diplomatic MovesAnalysts project three possible trajectories:Escalation*:* If the claim spurs actual arms negotiations, Beijing may increase military drills near Taiwan.Back‑channel Diplomacy*:* The statement might open informal channels that could later be formalized.Political Posturing*:* The claim could remain a rhetorical tool without concrete follow‑through.Monitoring official statements from the U.S. State Department and China’s Ministry of Foreign Affairs will be crucial to gauge whether this anecdote translates into policy action.

The British Comedy RevolutionSaturday Night Live UK's maiden voyage is almost complete, with Doctor Who star Ncuti Gatwa set to host the series one finale. The show has already been renewed for a bumper 12-week run in autumn, proving that Sky's investment has paid off. Predictions that SNL UK would be a national embarrassment have been categorically rubbished, as the series has delivered a stream of hilarious and gratifyingly weird material that has made it must-watch TV for comedy fans.From American Import to British InstitutionWhile the show hasn't been perfect—the opening monologues remain irredeemably American, and mining comedic gold from Keir Starmer seems to be an impossible task—the cast and writers have successfully adapted the SNL format for British audiences. The team has created a unique blend of American sketch show structure with distinctly British humor, creating something fresh and exciting in the comedy landscape.Standout Sketch MomentsThe series has produced numerous memorable sketches that showcase the cast's talent and the writers' creativity. From Tina Fey's debut episode featuring 'Undérage: The Anti-ageing Cream' to Riz Ahmed's 'Traitors: A Very Confident Mistake,' the show has consistently delivered sharp, relevant comedy. Jack Shep's portrayal of various characters, including a different member of the royal family in 'The Prince Andrew Plan,' has been particularly noteworthy, as has Emma Sidi's performance in multiple sketches.Cultural Impact and ReceptionSNL UK has successfully carved out its identity separate from its American counterpart while maintaining the core elements that made the original show successful. The series has been praised for its willingness to tackle sensitive subjects with humor, such as the sketch about 'The Traitors' that addressed issues of race in reality TV. The show's unique blend of surrealism, character comedy, and social commentary has resonated with audiences and critics alike.The Future of British Sketch ComedyWith the renewal for a second season, SNL UK is poised to become a significant player in British comedy. The show's success demonstrates that there is an appetite for sketch comedy that is both globally relevant and distinctly local. As the cast and writers continue to develop their unique voice, SNL UK has the potential to influence the broader comedy landscape and launch the careers of its talented performers, much like the original SNL has done for decades.

Runway, the New‑York‑based AI video‑generation startup valued at $5.3 billion, announced a strategic shift toward building “world models” – AI systems that learn from observational video data – positioning itself directly against Google’s Genie and other deep‑pocketed rivals.Runway's Pivot from Video Generation to World ModelsFounded in 2018 by three NYU Tisch alumni—two from Chile and one from Greece—Runway first gained traction with its Gen‑4.5 video‑generation model, powering workflows for Lionsgate, AMC Networks and the film Everything Everywhere All At Once. In December 2025 the company released its first world model and plans a second launch within the year, aiming to create AI that “understands how the world works” rather than merely processing text.Co‑founders: Anastasis Germanidis (co‑CEO), Cristóbal Valenzuela (co‑CEO), Alejandro Matamala‑Ortiz (Chief Innovation Officer)Current footprint: 155 employees across New York, London, San Francisco, Seattle, Tel Aviv and TokyoKey product evolution: from “anyone a filmmaker” to “anyone a great filmmaker” and now to “AI that can simulate reality”Funding Milestones and Revenue GrowthRunway’s capital raise and revenue trajectory underscore the high‑stakes nature of the world‑model race.Total capital raised: $860 millionLatest round (Feb 2026): $315 million from strategic partners including AMD Ventures and NvidiaValuation: $5.3 billionAnnual recurring revenue (Q2 2026): $40 million addedCompetitor funding: Luma AI ($900 million), World Labs ($1.29 billion), OpenAI (~$175 billion), Alphabet (parent of Google) $4.86 trillionImplications for Hollywood, Robotics, and Drug DiscoveryThe shift to world models could ripple across several high‑impact sectors.Media & Entertainment: Faster, AI‑driven editing and content creation for studios and ad agencies.Robotics & Gaming: Simulated environments for training autonomous agents without costly physical trials.Life Sciences: Potential to accelerate drug discovery and climate modeling by running “digital twin” experiments.Runway’s recent robotics unit already reports real‑world deployments, hinting at cross‑modal applications that combine video, sensor and textual data.Future Outlook: Can Runway Outpace Deep‑Pocketed Rivals?Experts agree that scaling world models will hinge on compute access and sustained funding.Compute challenge: Need for dedicated large‑scale GPU clusters; Runway currently partners with CoreWeave and Nvidia but has not disclosed dedicated capacity.Competitive pressure: Google’s Genie model, Meta’s research, and well‑funded startups are all pursuing similar multimodal AI.Strategic advantage: Founder diversity and a scrappy, revenue‑first culture may allow Runway to iterate faster than Silicon‑Valley incumbents.If Runway can translate its video‑generation dominance into robust world models, it could become a foundational AI infrastructure provider. Failure to secure the required compute or to demonstrate clear cross‑industry value could see it eclipsed by better‑funded rivals.

Executive Summary: Pound Slips as Burnham’s Leadership Bid LoomsSterling is on track for its worst week in 18 months, slipping almost 2% to $1.336 – the deepest weekly decline since the November 2024 U.S. election – after traders priced in a potential challenge to Prime Minister Keir Starmer from Manchester mayor Andy Burnham.Leadership Tensions Trigger Daily Dollar LossesThroughout the week the pound fell against the dollar each day, driven by speculation that Burnham will contest the Labour leadership after announcing his intention to run for the Makerfield parliamentary seat. The prospect of a less market‑friendly premier intensified the sell‑off.Market Numbers: Currency and Gilt ReactionsSterling down ~3 cents (‑2%) to $1.336, a five‑week low.UK 10‑year gilt yield rose to 5.17%, the highest level since 2008.UK 30‑year gilt yield jumped to 5.84%, up 19 basis points from earlier in the week.US and German sovereign yields also rose, but the UK increase outpaced them.Broader Implications for UK Fiscal DisciplineAnalysts warn that a Burnham premiership could loosen fiscal rules, prompting higher borrowing to fund increased spending. The sell‑off reflects fears of an “elevated political risk premium” on UK financial assets, echoing concerns from the 2022‑23 “Liz Truss” episode.Research director Kathleen Brooks (XTB) noted Burnham is perceived as the least market‑friendly Labour candidate, while macro‑research head Bill Diviney (ABN Amro) highlighted Burnham’s strong public approval as a counterbalance.Outlook: Volatility Likely Until Leadership Outcome ClarifiesMarket strategists expect continued gilt volatility and pressure on sterling until Burnham either secures a parliamentary seat and formal leadership bid or the Labour leadership settles around Starmer. Continuity in the Treasury, such as retaining Chancellor Rachel Reeves, could mitigate some of the fiscal‑risk premium.

Tesco’s chief executive, Ken Murphy, saw his total remuneration climb to £10.8 million for the 2025‑26 financial year, up by roughly £1 million from the previous period. The boost reflects the supermarket’s strongest market‑share performance in a decade and a shift in the company’s long‑term bonus criteria. Ken Murphy’s Compensation Package Surpasses £10m Amid Record Market Share The annual report details a pay structure that combines a higher basic salary, a sizable annual bonus and a long‑term incentive tied to shares. Basic pay: £1.54 million (3% increase) Annual bonus: £3.4 million Long‑term bonus: £5.7 million (includes company shares) Financial Breakdown: £10.8m Pay, Bonus Structure and Shareholder Returns The composition of Murphy’s pay highlights where Tesco is rewarding performance: Full payout of cash‑flow and earnings‑linked components. Full credit for carbon‑reduction initiatives, such as the rollout of electric delivery vehicles. Reduced credit for the food‑waste target – only 25% of the maximum possible, after the goal was missed. Minimal credit for DEI metrics – just 1 percentage point out of a possible 8.3. What the Pay Rise Signals for UK Grocery Competition Tesco now commands 28.1% of the UK grocery market, up from a low of 26.5% in 2020 and approaching its historic peak of nearly 32% in 2007. The rise in market share has been driven by weaker performance from rivals Asda and Morrisons. By linking future bonuses to market‑share targets rather than food‑waste reductions, the pay committee signals a strategic focus on growth and competitive positioning. Future Outlook: Bonus Targets and Market Share Ambitions Looking ahead, Tesco aims to reach a 30% market‑share milestone by the end of the next bonus cycle, while maintaining its long‑term goal of cutting food waste by 50% by 2030. The removal of the food‑waste metric from the 2026‑29 bonus scheme suggests that executive incentives will increasingly reward market‑share gains, potentially prompting other UK retailers to reassess their own compensation frameworks.

The LeadOsaurus has introduced an innovative open-source, Apple-only LLM server that allows Mac users to seamlessly switch between local and cloud AI models while maintaining data privacy on their own hardware. This development addresses growing concerns about AI token costs and security by providing a user-friendly interface that runs AI in a hardware-isolated virtual sandbox.The Evolution from Dinoki to OsaurusOsaurus evolved from the idea for a desktop AI companion called Dinoki, which Osaurus co-founder Terence Pae described as a sort of "AI-powered Clippy." Dinoki's customers had questioned why they should buy the app if they still had to pay for tokens—the usage units AI companies charge for processing prompts and generating responses. This concern led Pae to develop Osaurus as a solution that allows users to run AI locally on their Macs, accessing files, browsers, and system configurations without relying on cloud services.Technical Capabilities and Model SupportOsaurus can flexibly connect with locally hosted AI models or cloud providers like OpenAI and Anthropic, allowing users to choose which AI models best fit their needs. The platform supports various models including MiniMax M2.5, Gemma 4, Qwen3.6, GPT-OSS, Llama, and DeepSeek V4. It also supports Apple's on-device foundation models, Liquid AI's LFM family of on-device models, and cloud connections to OpenAI, Anthropic, Gemini, xAI/Grok, Venice AI, OpenRouter, Ollama, and LM Studio. As a full MCP (Model Context Protocol) server, it provides access to tools for MCP-compatible clients and ships with over 20 native plugins for Mail, Calendar, Vision, macOS Use, XLSX, PPTX, Browser, Music, Git, Filesystem, Search, Fetch, and more. Recent updates have also added voice capabilities.User Adoption and Market PositionSince launching nearly a year ago, Osaurus has been downloaded over 112,000 times according to its website. The platform distinguishes itself from similar tools like OpenClaw or Hermes by offering an easy-to-use interface for consumers rather than developers, while addressing security concerns through a hardware-isolated, virtual sandbox that limits the AI's scope and keeps users' computers and data safe. Currently, Osaurus' founders, including co-founder Sam Yoo, are participating in the New York-based startup accelerator Alliance.The Future of Local AI and Business ApplicationsOsaurus' founders are exploring potential business applications, particularly in sectors like legal services and healthcare where running local LLMs could address privacy concerns. The team believes that as local AI models become more powerful, they could reduce demand for AI data centers. Pae noted that "the intelligence per wattage—which is like the metric for local AI—has been going up significantly," with local AI evolving from barely being able to finish sentences last year to now being able to run tools, write code, access browsers, and perform various tasks. The vision is for businesses to deploy Mac Studios on-premise, using substantially less power than traditional data centers while maintaining cloud-like capabilities.

Finland Standdown Follows Drone Scare Amid Regional TensionsFinland has stood down its defence forces after sounding an alarm over suspected drone activities in its airspace. The authorities said on Friday that suspected drone activity above the Helsinki region no longer posed a threat and that the situation was returning to normal hours after launching an emergency response, including the launch of fighter jets and closure of the capital's airport.Emergency Response Measures in HelsinkiThe Helsinki City Rescue Department had warned the nearly 2 million inhabitants of Finland's Uusimaa region to stay indoors starting about 4am local time (1:00 GMT), as fighter jets were scrambled. Helsinki's airport was also closed for about three hours. Later, President Alexander Stubb wrote on X that authorities had "demonstrated their readiness and capacity to react", adding that the country was now facing "no direct military threat".Kimmo Kohvakka, director general for rescue services at the Ministry of the Interior, called the response a "precautionary measure" and said "daily life can continue."Rising Regional Security ConcernsThe alarm illustrates the tension stalking the region as Finland and the Baltic states eye Russian aggression and daily missile and drone attacks amid Moscow's continued war on Ukraine.The Baltic states of Estonia, Latvia and Lithuania have reported a series of suspected Ukrainian drones headed for Russia entering their airspace, prompting domestic criticism over their ability to respond to military threats.In March, two drones crossed into Finnish territory and crashed after flying low over the sea and southeastern Finland. Finnish authorities did not indicate the source of Friday's drone activity. However, defence forces operations chief Kari Nisula suggested that Finland had received information from Ukraine about drones potentially straying into the country.Political Fallout in LatviaThe situation has led to a full-blown government crisis in Latvia. Prime Minister Evika Silina resigned on Thursday after a coalition partner pulled support. The move followed the ousting of the defence minister after a drone crashed at a fuel storage facility.Escalating Drone WarfareThe incident in Finnish airspace unfolded as Ukraine maintained its drone attacks on Russian oil and energy infrastructure, and Kyiv continued counting the costs of a huge strike that killed two dozen people.Russia's Ministry of Defence said on Friday that its air defence systems shot down 355 Ukrainian drones targeting Moscow overnight, as well as the border regions of Belgorod, Bryansk and Kursk.Among the targets was an oil refinery in the central city of Ryazan, about 200km (125 miles) southeast of Moscow, according to the commander of Ukraine's drone forces. The attack killed three people and wounded 12, regional Governor Pavel Malkov wrote on Telegram. Two high-rise apartment buildings were struck, he said, while debris fell on the grounds of an industrial enterprise.Civilian Casualties MountMeanwhile in Kyiv, the death toll from a Russian barrage on an apartment building on Thursday rose to at least 24 people, including three children, Ukrainian President Volodymyr Zelenskyy said. Forty-eight people were wounded.Diplomatic Developments Amid ConflictAmid the ongoing violence, Russia and Ukraine have moved ahead with a prisoner swap that saw 205 POWs repatriated on each side on Friday. It was the first step of a swap that is planned to ultimately see 1,000 people on each side return home.The two sides also conducted an exchange of those killed in the fighting, with Russia handing 526 bodies to Ukraine and receiving 41 in return. Both Kyiv and Moscow thanked the United Arab Emirates for mediating the swap.Zelenskyy wrote on social media that most of the prisoners returned to Ukraine had been in Russian captivity since 2022. "We will continue to fight for every single person who remains in captivity," he said.
