The Global Obesity Landscape: Not a Uniform EpidemicA continuing rise in obesity around the world is not inevitable, research suggests, with rates in some countries levelling off or potentially in decline. Researchers say focusing on what has been described as a global epidemic of obesity hides large variations in trends across different countries, sexes and age groups.Majid Ezzati, a professor of global environmental health at Imperial College London and author of the study, said: "I think the thing that's really important is this diversity exists even across countries that have really similar economic, environmental, technological features. So countries may look the same on the surface of it but obesity looks different."Comprehensive Analysis Reveals Complex PatternsWriting in the journal Nature, the international team, which involved a network of almost 2,000 researchers, described how for each country they calculated the change in the prevalence of obesity each year between 1980 and 2024. They drew on data from 4,050 population-based studies involving 232 million participants aged five years and above.They found that the prevalence of obesity increased in almost all countries over the 45-year period. However, in most high-income countries, a rapid rise in the prevalence of obesity has been replaced by a slower increase, a plateau, or a potential decline.Regional Variations in Obesity PrevalenceThe rate of growth in obesity is slowing in adults in the US and UK, reaching a prevalence of 40-43% and 27-30% respectively in 2024. Obesity is increasing steadily in Finland, has plateaued in Germany and may have started to decline in France, where 24-25%, 20-23% and 11-12% of adults respectively were thought to have the condition in 2024.Slowdowns were often seen in children and adolescents before adults. For the former group, the slowdown started as early as 1990 in Denmark and rates stabilised in most high-income countries by the mid-2000s. Obesity has plateaued in boys and girls in the UK, US, Germany and Japan at prevalences of 10-12%, 20-23%, 7-12% and 3-7% respectively.Meanwhile, obesity among young people and adults in many low-income and middle-income countries continues to rise and in some cases this is accelerating.Understanding the Drivers Behind Divergent TrendsThe team say it is important now to unpick what is behind the trends in different countries. The situation is complex: while there may be shared reasons for obesity, such easy access to unhealthy foods or a decrease in physical activity, the team say country-specific factors rooted in social, economic and policy considerations could also be important, from perceptions around body image to the presence or absence of interventions such as healthy school meals.Naveed Sattar, a professor of metabolic medicine at the University of Glasgow, who was not involved in the work, said the study highlighted how obesity trends were diverging sharply across countries. "English-speaking nations are doing particularly poorly, with the UK now among the countries with the highest obesity levels worldwide," he said.Sattar said it was encouraging that some countries appeared to have reached a plateau in obesity rates. "Understanding what has worked in those settings is crucial as it could help shape more effective public health strategies for the UK," he said, although he noted there could be country-specific aspects or customs at play.Future Outlook and Potential InterventionsHe said the rapid rise in obesity across many developing countries was especially concerning, not least as it could result in increases in diabetes and cardiovascular conditions.He added: "Looking ahead, it will be important to see how wider use of effective weight-loss medicines affects obesity trends, particularly in the UK and the United States. Recent signs of stabilisation in the USA suggest there may be room for cautious optimism. Combining evidence-based medicines with strong public health measures could begin to shift obesity rates in the right direction."

Morning Birdwatch in the Mallee ForestWhile on a breakfast break in the Mallee forest near Lake Gilles, guide Steve Potter heard a repetitive whistling that led the party to pause their coffee and cornflakes in search of its source.Spotting the Copperback Quail-ThrushThe call guided the group to a large, plump bird walking purposefully beneath a bush: a copperback quail-thrush (Cinclosoma clarum). Its snow‑white eyebrow, moustache and belly contrast sharply with a black throat and a radiant copper‑coloured back, giving the species its English name.Endemic to South and Western AustraliaTerrestrial songbird, rarely fliesRecently split from the chestnut quail‑thrushScientific name means “luminous tail‑wagging thrush”Ecological Significance of the Copperback Quail-ThrushUnlike many songbirds, quail‑thrushes spend most of their time on the forest floor, making them key indicators of ground‑level habitat health. Their presence signals intact understory vegetation and a balanced invertebrate community, both crucial for the broader Mallee ecosystem.Conservation Outlook for Terrestrial SongbirdsContinued protection of Mallee habitats around Lake Gilles is essential to preserve the copperback quail‑thrush and related species. Ongoing monitoring and community‑led birdwatching tours can raise awareness, supporting conservation measures that safeguard these ground‑dwelling birds for future generations.

Smithsonian's Monumental Celebration of America's 250 Years To paraphrase the musical Rent, 131,487,300 minutes – how do you measure, measure 250 years? Especially in a country navigating an election year fraught with divisions and disagreements over basic facts? That is the challenge facing the Smithsonian National Museum of American History in Washington DC as it marks the semiquincentennial of US independence. The museum's answer is with 250 objects that tell the American story, ranging from a revolutionary war-era gunboat to gloves worn by a "Miracle on Ice" hockey player, from Thomas Jefferson's desk to a Donald Trump fan's "Make America great again" hat. A Museum-Wide Journey Through American History Opening on 14 May, "In Pursuit of Life, Liberty & Happiness" will display 250 objects encompassing 250,000 sq ft across all three floors of the museum. They range from old to new, from big to small and from sublime to mundane. Seventy-six of them – many rarely or never seen by the public – will be concentrated in cases lining the entry halls, while the remainder will be embedded throughout the museum's existing galleries, connected by a "ribbon" design to guide visitors on a historical treasure hunt. Each is paired with an action verb to underscore the view of democracy as a "highly participatory sport." Among the star attractions is the Philadelphia, a 53ft, flat-bottomed wooden gunboat constructed in the chaotic, sweltering summer of 1776. On a recent preview tour, visitors stepped into a climate-controlled enclosure at the museum where the air was thick with the scent of 100% acetone. Behind viewing windows that allow the public to see the work in progress, two conservators clad in headlamps and respirators were meticulously wielding soft and stiff bristle brushes, dental picks and wooden dowel rods to strip away decades of accumulated lacquer from a rusted iron cannon and its surrounding timber. By the Numbers: The Scale of the Exhibition The exhibition features 250 objects spread across 250,000 square feet of museum space. Seventy-six of these objects – many rarely or never seen by the public – will be concentrated in cases lining the entry halls. The Philadelphia gunboat itself weighs 16,000 pounds and was constructed in 1776. The wreck languished underwater for 159 years before being salvaged in 1935, fully intact with its armament and hundreds of artifacts scattered across its deck. When raised, the boat revealed about 600 to 800 items, including cannons, carriages, wheels, a stew pot, a melting pot for pitch, shoe leather, buttons from regimental coats, and even a leather button that was probably from someone's breeches. Reframing America's Complex Narrative "How do you structure a commemoration, celebration and time for reflection?" asks Anthea Hartig, the museum's director. "What we landed on were those moments where individuals or communities had fought for recognition and advocated for their own sense of identity and self in their role in creating and becoming a part of the United States. But we also wanted to do the playful." Hartig describes the US as "amazing, beautiful, complicated", and cites the African American writer James Baldwin's celebrated observation: "American history is longer, larger, more various, more beautiful, and more terrible than anything anyone has ever said about it." The exhibition captures both the monumental and the intimate aspects of American history. Alongside iconic items like Thomas Jefferson's portable desk on which he drafted the Declaration of Independence, the Star-Spangled Banner that inspired the national anthem, and George Washington's military uniform, are personal artifacts like a faux-pearl necklace worn by Abigail Adams in the mid-18th century. The Future of Historical Commemoration Hartig adds: "We believe that this anniversary is so important not only to the nation but the world, and that our past 250 years are filled with so much history that it takes an entire museum to do it justice." The exhibition also incorporates modern technology to enhance the visitor experience, including a virtual reality experience that transports visitors back to the Philadelphia's construction 250 years ago. As the museum continues to preserve and interpret America's complex past, the exhibition represents a new approach to historical commemoration – one that embraces the full spectrum of American experiences, from the revolutionary to the contemporary, and from the sublime to the mundane.

The Portrait That Merges Masculine Power and Feminine VulnerabilityThe Guardian features Marisol Mendez’s striking photograph of Marta Salinas, a Bolivian theatre actor, standing nude in a bull costume. The work confronts traditional Bolivian representations of women by foregrounding masculine traits—ambition, competitiveness, and the symbolism of the bull—while celebrating bodily autonomy.The Creation of the Bull‑Costume PhotographConceived in 2019, the image emerged from Mendez’s dream of a half‑woman, half‑animal figure in a field. Drawing on the waka tokori dance, which reenacts Bolivian bullfighting where men only taunt the bull, she used the bull as a symbol of masculinity. The setting—a fruit‑and‑bee farm outside Cochabamba—was suggested by Mendez’s mother, who acted as chauffeur and logistical support.Photographer: Marisol Mendez (Bolivia)Subject: Marta Salinas, theatre actor (Bolivia/Argentina)Series: Madre – a study of womanhood and archetypesPrize: 2026 Saltzman‑Leibovitz prize winnerExhibition: Photo London, Olympia, until 17 May 2026Cultural Resonance of Gender Fluidity in Bolivian ArtThe photograph challenges the media’s habit of portraying Bolivian women in strictly feminine roles. By presenting a nude figure who embraces masculine energy, Mendez questions the automatic labeling of such women as “lesbian” and pushes for nuance in gender representation. The work also references the influence of US photographer Ryan McGinley, whose non‑sexualized nudes inspired Mendez’s approach.What Lies Ahead for Mendez and the Madre SeriesWith the Saltzman‑Leibovitz prize spotlighting her practice, Mendez is poised to expand the Madre series internationally. Upcoming shows, such as the Photo London exhibition, will introduce broader audiences to her interrogation of archetypes like the Virgin Mary versus Mary Magdalene. Critics anticipate that her blend of personal narrative, cultural critique, and bold visual language will continue to shape contemporary discourse on gender and identity in Latin American photography.

The Geopolitical Fracture of Eurovision 2026The buildup to the Eurovision 2026 grand final in Vienna has been defined by a deepening schism between the contest's musical aspirations and its political reality. The slogan 'United by music' hangs increasingly ironic as five nations—including Spain, the Netherlands, and seven-time winners Ireland—have boycotted the event in protest at Israel’s participation. The first semi-final saw chants of 'Free Palestine' echo through the Wiener Stadthalle, signaling that the contest has evolved from a simple song competition into a stage for geopolitical point-scoring. With an expected global audience of 150 million, the event faces the challenge of maintaining its escapist appeal while navigating a fractured political landscape.The 11 Bangers Defining the 70th AnniversaryDespite the controversy, the competition has delivered a diverse array of musical styles, ranging from indie rock to techno-ballads. The following entries represent the most compelling contenders for the 70th-anniversary crown:Finland – Liekinheitin: A techno-ballad described as a 'flamethrower,' featuring a classical violinist whose performance is so intense it reportedly snaps strings.Germany – Fire: A Dua Lipa-esque dance-pop anthem performed by a solo female artist, backed by a proven winning formula of English lyrics and love themes.Norway – Ya Ya Ya: A stomp-rock track reminiscent of 00s indie bands like The Hives, offering a gritty alternative to the usual pop confections.Armenia – Paloma Rumba: A gnarly rock track lamenting office culture, complete with backflips and reams of paper thrown across the stage.France – Regarde !: A 'poperatic' epic reminiscent of Rosalía, featuring a 17-year-old prodigy with opera-tinged vocals.Australia – Eclipse: A big-lunged ballad by established star Delta Goodrem, aiming to secure Australia's first-ever win.Greece – Ferto: A bouncy dance anthem mixing traditional instrumentation with Super Mario bleeps and house beats.Cyprus – Jalla: A Shakira-adjacent anthem that has sparked controversy for being deemed 'unsophisticated' by local critics.Lithuania – Sólo Quiero Más: A man-v-machine ballad warning against AI, performed by a drag artist painted head-to-toe in silver.Bulgaria – Bangaranga: A sassy club tune with Alanis Morissette-esque lyrics and a teeth-rattling drumbeat.Austria – Tanzschein: A quirky synth-pop number urging clubbers to 'unleash their inner animal,' backed by animatronic gorillas and lions.The Winning Formula: Data and DemographicsAccording to decades of Eurovision data, the winning formula remains surprisingly consistent: solo female artists performing love-themed songs in English. Germany’s entry, Fire, perfectly fits this demographic profile, and the artist boasts a combined following of 2.5 million on Instagram and TikTok. Furthermore, the trend of 'poperatic' vocals—seen in recent winners like Switzerland’s Nemo and Austria’s JJ—continues to dominate the charts, suggesting that operatic flourishes are a reliable pathway to the top of the scoreboard.Spectacle Over Substance: The Irony of 'United by Music'The staging of these entries highlights a shift in the competition's focus. While the music remains a core component, the visual spectacle is becoming equally important. From the literal pyrotechnics of Finland to the hyperactive staging of Greece, the event is prioritizing immersive experiences over traditional musicality. This aligns with the broader trend of using Eurovision as a platform for social commentary, as seen in Lithuania’s anti-AI theme and Armenia’s critique of corporate culture.The Future of Eurovision: Controversy as the New NormalThe 2026 contest suggests that controversy is no longer an anomaly but a defining feature of the event. The boycotts and protests indicate that Eurovision is increasingly viewed as a political arena rather than just a pop festival. As the competition enters its 70th year, the line between entertainment and activism is blurring, suggesting that future editions will likely continue to balance the escapist nature of the show with the pressing geopolitical realities of the world stage.

After battling France to a 2-2 draw after 90 minutes and a 3-3 draw after extra time, Argentina won 4-2 on penalties. The Legacy of the World Cup Eight countries have won the World Cup in its 92-year history. The tournament continues to be a pinnacle of achievement in international football.

The Upcoming Vote on Squad Cost Ratio in the ChampionshipEFL Championship clubs are set to vote on a proposal that would align their financial framework with the Premier League from next season. The plan replaces the existing profitability and sustainability (P&S) rules with a squad cost ratio (SCR) system that caps player‑related spending at 85% of football revenue. An annual equity injection of roughly £10m would be allowed to count as revenue, expanding clubs’ spending capacity.Financial Numbers Behind the Proposed ChangesCurrent P&S loss limit in the Championship: £39m over a three‑year period.Proposed SCR cap: 85% of football revenue.Equity injection counted as revenue: about £10m per year.Average League One owner investment this season: £9.6m (up from £2.6m four years ago).League One salary‑cost management protocol (SCMP) would fall from 60% to 50% of turnover.Potential Shift in Competitive Balance Across the EFLThe divergent reforms would likely widen the financial gap between the Championship and League One. Championship clubs would gain greater freedom to invest in squads to chase promotion, while League One clubs would be forced to tighten budgets, potentially boosting the medium‑term value of their assets and attracting external buyers.What the Vote Outcome Could Mean for English FootballBoth proposals require at least 16 of the 24 clubs in each division to vote in favour. Sources suggest the votes could be tight, reflecting differing views on financial regulation. If adopted, the Championship would move in step with the Premier League’s SCR, while League One would operate under a stricter SCMP, reshaping spending dynamics and possibly influencing promotion‑relegation battles in the coming seasons.

The Lawsuit Against Meta California’s Santa Clara county has sued Meta Platforms, alleging it has profited from Facebook and Instagram ads promoting scams in violation of California’s false advertising and unfair business practices laws. Allegations of Tolerating Fraudulent Advertising The lawsuit – filed on Monday in Santa Clara county superior court on behalf of all California residents – accuses the social media giant of tolerating fraudulent advertising on a global basis. The suit seeks restitution, civil damages and an order prohibiting Meta from engaging in unfair business practices. Revenue from High-Risk Scam Ads Citing leaked internal documents first reported by Reuters last year, the complaint alleges that the company earned as much as $7bn in annual revenue from so-called “high-risk” scam ads which show clear signs of being fraudulent. Meta's Response and Defense Meta said it intends to defend itself against the claim. “This claim relies on Reuters reporting that distorts our motives and ignores the full range of actions we take to combat scams every day,” said a Meta spokesperson, Andy Stone. “We aggressively fight scams on and off our platforms because they’re not good for us or the people and businesses that rely on our services.“ The Impact on Users and the Legal Proceedings In the suit, Santa Clara alleges that Meta materially contributed to an epidemic of fraud by allowing middlemen to sell accounts to place ads that were protected against enforcement, and targeting scam ads at users who had clicked on similarly bogus offerings in the past. The county will retain full control over decisions involving the case, and outside law firms will only be paid if the county wins.

Iga Swiatek's Dominant Performance Iga Swiatek gave another indication that she might be back to her brilliant best after destroying Jessica Pegula 6-1, 6-2 on Wednesday and breezing into the Italian Open semi-finals. The Match Details A three-time champion in Rome, Swiatek took little more than an hour to take care of fifth seed Pegula on centre court, in a show of force on her preferred surface not seen since she last won the French Open two years ago. Upcoming Matches and Potential Opponents Swiatek has set up a clash with either second seed Elena Rybakina or Elina Svitolina in the last four. A potential decider with reigning Roland Garros champion Coco Gauff awaits for the winner of that last-four match-up in Saturday’s final. Emma Raducanu's Comeback Meanwhile, Emma Raducanu will make her comeback from illness at the Internationaux de Strasbourg next week. The British No 1 has not played a tournament since Indian Wells in March because of a post-viral illness after she first fell unwell in February, pulling out of four successive events. Road to the French Open Raducanu travelled to Rome and practised ahead of the current Italian Open but ultimately decided she was not quite ready to return. Taking a wild card into Strasbourg means the 23-year-old will gain valuable time on the clay ahead of the French Open, which begins on May 24.
