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.

Roberto Martinez told Reuters in Lisbon that age is "only a number" and that Cristiano Ronaldo will be judged on the same day‑to‑day standards as every other player ahead of the 2026 World Cup. The coach’s comments come as Portugal finalises a squad that could feature the 41‑year‑old striker in a tournament that begins in less than a month.Ronaldo’s Form‑Based Evaluation Ahead of World Cup 2026Martinez stressed that his selection process focuses on training performance, tactical fit, and immediate impact rather than past accolades. He said, "We manage the Cristiano Ronaldo that plays for the national team trying to get into the squad for 2026, not the iconic figure." This signals a shift from the symbolic "monument to past glory" narrative that has surrounded the captain.Portugal will have five substitutions per match, allowing a more fluid rotation of players.Martinez views the squad as a "starting team and a finishing team" with interchangeable roles.Numbers Behind the Narrative: Goals, Appearances, and Substitution RulesKey statistics highlighted by the coach include:143 international goals – the all‑time record for a male player.25 goals in 30 appearances under Martinez, a goals‑per‑game ratio of 0.83, higher than under any previous Portugal coach.At 41 years old, Ronaldo could become the first player to feature in a sixth World Cup.The new five‑substitution rule gives Martinez tactical leeway to deploy Ronaldo in specific moments, such as late‑game attacks or set‑piece situations, without requiring him to start every match.Implications for Portugal’s Tactical Flexibility and Squad MoraleBy anchoring selection to form, Martinez aims to preserve squad harmony and avoid the "noise" that surrounds the captain’s presence. He noted that Ronaldo’s "elite brain" and daily pursuit of improvement make him valuable beyond raw statistics, contributing to space creation and defensive discipline.Enhanced squad morale: players understand that merit, not reputation, dictates playing time.Tactical adaptability: the coach can switch between a "starting" and "finishing" lineup, using Ronaldo’s experience in high‑pressure moments.What Lies Ahead: Potential Scenarios for Ronaldo in North AmericaLooking forward, Martinez outlined three realistic pathways:Full‑starter role if training metrics and match fitness remain elite.Impact substitute leveraging the five‑sub rule to introduce Ronaldo late in games where a goal is needed.Mentorship focus where his presence influences younger attackers, even if minutes are limited.Regardless of the scenario, the coach affirmed that "the players are always on the pitch on merit," and that the final squad will reflect the evidence gathered in the days leading up to the tournament.

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.

Channel 5 will air a daily highlights show of the 2026 Commonwealth Games, taking over a role the BBC has held since 1954, after the public‑service broadcaster opted out of any coverage due to financial pressures.Channel 5 Wins Commonwealth Games Highlights Rights via TNT Sports Sub‑LicenseChannel 5 secured the highlights package by sublicensing from TNT Sports, the live‑rights holder owned by Warner Bros Discovery (WBD). The agreement ensures a daily programme on Channel 5 while the Games remain available on all HBO Max tiers. The move follows TNT Sports outbidding the BBC for live rights last year.Financial Stakes: £83 bn Paramount‑Skydance Takeover and BBC Cost‑Cutting ContextParamount Skydance is in the process of acquiring WBD in a $110.9 bn (£83 bn) deal, pending regulatory approval.The BBC announced a £500 m efficiency drive, targeting the loss of 1,800–2,000 jobs and a reduced sports budget.WBD will deliver more than 600 hours of live coverage from Glasgow, which it will now also provide as highlights to Channel 5.Implications for UK Broadcast Landscape and Public‑Service MandateThe BBC’s withdrawal marks a significant shift in its public‑service remit, reflecting a strategy focused on cheaper clip‑rights and digital audiences rather than full‑event coverage. Channel 5 is expanding its sports portfolio, recently adding live England T20 cricket, the Club World Cup, and weekly NFL games, positioning itself as a challenger to traditional broadcasters.What This Means for Future Multi‑Sport Event Rights and CompetitionAnalysts expect more commercial tender processes for multi‑sport events, with broadcasters prioritising cost‑effective highlights packages over costly live rights. The deal could accelerate the fragmentation of sports rights across free‑to‑air and streaming platforms, and may prompt the BBC to further re‑evaluate its role in covering events with modest viewership.

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.

Executive Overview: A Memoir of Hope Amid SegregationBacktalker by Kimberlé Crenshaw is a candid autobiography that traces her upbringing in Jim Crow Ohio, the loss of family property through eminent‑domain, and the intellectual journey that produced the theory of intersectionality. The Guardian’s review frames the work as both a personal testament and a call to recognize ongoing racial inequities.Crenshaw’s Journey from Segregated Ohio to Intersectionality TheoryThe narrative begins with childhood episodes—being cast as a witch instead of a princess, a Black family’s defiant return to a drained public pool, and her father’s brief legal career—illustrating the daily “backtalk” that forged her resilience. At Cornell she discovered Derrick Bell’s scholarship, and at Harvard Law she confronted the stark absence of Black faculty, prompting protests that foreshadowed her later legal activism. A pivotal case involving Emma DeGraffenreid’s GM lawsuit revealed the limits of Title VII, inspiring Crenshaw to articulate the concept of intersectionality.Publication Details and PricingPublisher: Allen LaneRelease date: 2026Price: £25Available through: guardianbookshop.comWhy Crenshaw’s Story Reshapes Understanding of Race, Law, and Public MemoryThe review underscores that Crenshaw’s personal history mirrors broader systemic patterns—racialized eminent‑domain, under‑representation in elite academia, and the legal blind spot that ignored overlapping discrimination. By linking intimate family anecdotes to national moments such as the Clarence Thomas hearings, the OJ Simpson trial, and Barack Obama’s election, the memoir demonstrates how individual “backtalk” can influence collective legal and cultural narratives.Looking Ahead: The Enduring Relevance of BacktalkerAs debates over voting rights, reparations, and campus diversity intensify, *Backtalker* is positioned to become a staple in both scholarly curricula and public discourse. Readers and educators are likely to cite Crenshaw’s account when arguing for more nuanced anti‑discrimination policies that address the intersecting axes of race and gender.

The Lead Pollution ReturnWood heating is reintroducing lead into the air of local communities and homes, according to a systematic investigation by academics from the University of Massachusetts Amherst. The research reveals that despite lead being banned as an additive in petrol more than 25 years ago due to its overwhelming neurotoxicity, the metal is now making a comeback through wood burning.Scientific FindingsThe research began by analyzing samples of particle pollution from five suburban and rural towns in the northeast US. Scientists looked for tiny particles of potassium that are emitted when wood is burned, as well as particles containing lead. Samples from seven winters revealed clear associations between potassium and lead - when there were more wood burning particles in a daily sample, there was more lead in the air."For the most part, wood burning produces significant amounts of particle air pollution, and a small but measurable fraction of this is a powerful neurotoxicant," said Prof Richard Peltier, the senior author of the research.Geographic PatternsThe project was extended to 22 other towns across the US, with the relationships between lead and potassium varying from place to place. The strongest associations were found in the Rocky Mountains. By factoring in temperature effects, the researchers strengthened their conclusion that the additional lead came specifically from wood burning.Health ImplicationsAlthough the lead concentrations found were less than US legal limits, health experts emphasize that any exposure to the metal is harmful. "The most logical answer is that it comes from uptake in the soil, probably riding along with the nutrients and water that trees need. Once in the tree, it deposits in the tree's tissues and remains until that tree is burned," explained Tricia Henegan, a PhD student at Umass Amherst and the first author on the research.Historical ContextLead was used globally as a petrol additive from the 1920s and found its way into oceans, soils and people. Evidence on harms from exposure to lead were systematically suppressed by industry for decades. Today it is acknowledged that lead exposure causes harm at all stages of life and comes from many sources.Policy RecommendationsThe researchers suggest that their findings challenge previous assumptions that lead in wood smoke came primarily from waste wood covered with old lead paint. "The use of wood as an energy source is a relic of the past, one that should not be relived if given a choice. Although wood fuel use can feel nostalgic, it does have negative consequences on air quality, and therefore public health," Henegan concluded.

The Collapse of Cuba's Energy InfrastructureCuba is facing a total energy failure after Energy Minister Vicente de la O Levy admitted the country has absolutely no reserves of diesel or fuel oil. The national grid is in a critical state, operating solely on domestic crude, natural gas, and renewable sources after the fuel from a Russian tanker arrived in April. This admission marks a pivotal moment in the island's history, as the government struggles to maintain basic services amidst a severe fuel shortage.Quantifying the Blackout CrisisDuration of Outages: Residents are enduring blackouts lasting up to 22 hours or more, drastically reducing daily life and economic activity.Infrastructure Limitations: Despite installing 1,300 megawatts of solar power over the past two years, the system is inefficient due to grid instability and a lack of storage batteries.Supply Scarcity: Since December, only a single Russian-flagged tanker, the Anatoly Kolodkin, has delivered crude oil, a delivery made under strict humanitarian exceptions.Geopolitical Fallout and Supply Chain CollapseThe fuel crisis is not merely an economic failure but a geopolitical weaponization of energy. The US blockade has successfully choked off traditional supply lines from Venezuela and Mexico, which have halted shipments following President Donald Trump's executive order threatening tariffs on any nation trading with Cuba. The UN has condemned the blockade as unlawful, arguing it obstructs the Cuban people's right to development and basic rights to health and sanitation.The Path Toward EscalationThe situation is deteriorating rapidly, with reports of US military surveillance flights increasing near the island. Analysts suggest that as the humanitarian crisis deepens and the US government grows frustrated with negotiation progress, the risk of military intervention or a broader blockade is rising. With global oil prices soaring due to the US-Israeli war with Iran, Cuba's ability to import fuel is diminishing, pushing the island further toward a potential systemic collapse.

The Rise of Youth‑Led Thrift Resale in IndiaFacing stagnant wages and a tight job market, many Indian Gen Zers are turning to secondhand fashion as both a hobby and a source of income. Entrepreneurs like Astha Chhetri and Vishu Roy illustrate how a few thousand rupees of seed capital can evolve into a daily‑to‑daily business powered by social media.How Instagram Fuels a New Gig Economy for Vintage ClothingResellers spend sunrise to sunset curating, photographing, and posting reels on Instagram, WhatsApp and YouTube. The platforms act as virtual storefronts; 70% of sales for many sellers come directly from Instagram feeds. Consistency is crucial—one missed post can shrink visibility and revenue overnight.Daily routine includes sourcing stock, shooting product photos, replying to messages, and tracking shipments.Typical startup capital ranges from ₹5,000‑₹10,000.Average purchase price for buyers is ₹800‑₹1,500 per item.Market Size and Earnings: ₹33,000 crore Industry and Startup CostsIndia’s secondhand clothing market is estimated at ₹33,000 crore (£2.5 bn) annually. While individual sellers earn modest margins, the aggregate volume signals a sizable informal sector.Unemployment among 15‑29‑year‑olds projected at 10% in 2025 (Periodic Labour Force Survey).Most sellers operate without formal contracts, leading to income volatility—some months are profitable, others result in losses.Why the Informal Thrift Sector Is Reshaping Youth EmploymentThe model offers low entry barriers, flexible hours and immediate cash flow—advantages traditional jobs often lack. However, heavy reliance on algorithmic platforms creates systemic risk; a change in Instagram’s feed algorithm can cut sales dramatically.Benefits: minimal capital, autonomy, ability to monetize personal style.Risks: platform policy shifts, scams, lack of social security.What the Future Holds for India’s Secondhand Fashion MarketplaceAs digital penetration deepens, the thrift economy is likely to expand, attracting more micro‑entrepreneurs and possibly prompting regulatory attention around consumer protection and taxation. Sellers who diversify channels—combining Instagram with dedicated e‑commerce sites—may mitigate platform‑specific risks and sustain growth.
