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 However, in most high-income countries, a rapid rise in the prevalence of obesity has been replaced by a slower increase, a plateau, or a potential decline.Regional Variations in Obesity PrevalenceThe rate of growth in obesity is slowing in adults in the US and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.

The Lead: Russia's New Nuclear PowerhouseRussia has successfully test-launched the Sarmat intercontinental ballistic missile, a weapon that President Vladimir Putin proudly declares as 'the most powerful missile in the world.' This development comes just days after Putin suggested the fighting in Ukraine is nearing its end, marking a significant moment in Russia's nuclear arsenal modernization efforts. The Sarmat, designed to replace the aging Soviet-built Voyevoda missiles, represents a substantial leap in Russia's strategic capabilities and is scheduled to enter combat service by the end of 2026.The Technical Breakthrough: Understanding the Sarmat MissileThe RS-28 Sarmat, codenamed 'Satan II' in Western intelligence circles, is an intercontinental ballistic missile with a minimum range of 5,500km (about 3,400 miles). According to Putin, the missile has a maximum range exceeding 35,000km (21,750 miles) – a claim disputed by Western analysts who estimate the actual range to be approximately 18,000km (11,000 miles). Despite this discrepancy, both figures would theoretically allow the missile to reach virtually any target on Earth from Russian territory.Development of the Sarmat began in 2011, and it will eventually replace about 40 Soviet-built Voyevoda missiles. Notably, one test in September 2024 reportedly ended in a catastrophic failure, highlighting the challenges in developing such complex weaponry. The Sarmat reaches 35.3 meters (116ft) in length, 3 meters (9.8ft) in diameter, and weighs 208.1 tonnes, with a maximum payload capacity of 10 tonnes.The Specifications: Capabilities and Design FeaturesThe Sarmat represents a significant advancement over its predecessors in several key areas. Putin claims that while maintaining the power of the Voyevoda, the new missile offers higher precision. Its maximum payload of 10 tonnes allows it to carry multiple independently targetable re-entry vehicles (MIRVs), with Putin stating that the combined power of these warheads exceeds four times that of any Western counterpart.One of the Sarmat's most notable features is its ability to reach high speeds quickly and stop burning its engines sooner than traditional intercontinental ballistic missiles. According to Putin, this characteristic gives missile defense systems less time and fewer opportunities to detect, track, and intercept the incoming missile. Additionally, the Sarmat is capable of suborbital flight, meaning it can reach outer space but cannot maintain orbit or complete a full revolution around Earth.The Geopolitical Impact: Russia's Arms Race StrategyThe unveiling of the Sarmat is part of a broader Russian strategy to counter what Moscow perceives as an expanding US missile defense system. Putin has explicitly linked these new weapons to the US withdrawal from the 1972 Anti-Ballistic Missile (ABM) Treaty in 2001, which Russia viewed as destabilizing the strategic balance.Russian military planners fear that a robust US missile shield could tempt Washington to launch a first strike, targeting most of Moscow's nuclear arsenal with the expectation that only a few retaliatory missiles might penetrate the defenses. In response, Russia has developed not just the Sarmat but also the Avangard hypersonic glide vehicle (capable of flying 27 times the speed of sound), the Oreshnik intermediate-range ballistic missile, and is developing the Poseidon underwater drone and Burevestnik cruise missile.The timing of these announcements is particularly significant, coming as Russia claims progress in negotiations to end the war in Ukraine. The display of nuclear capabilities may serve as both a deterrent to Western intervention and a demonstration of Russia's continued military prowess despite the ongoing conflict.The Future Outlook: Implications for Global SecurityThe deployment of the Sarmat missile is likely to intensify the nuclear arms race between Russia and the United States. While Putin claims the missile can 'penetrate all existing and future antimissile defense systems,' the US is simultaneously developing its own 'Golden Dome' missile defense system, estimated to cost $1.2 trillion over the next 20 years.The Sarmat's entry into service by the end of 2026 will mark a significant shift in the global strategic balance. Its capabilities, particularly if they approach Putin's claims rather than Western estimates, could render current missile defense systems obsolete and force a complete reassessment of nuclear deterrence strategies.As Russia continues to modernize its nuclear arsenal while simultaneously engaging in what it claims are peace negotiations over Ukraine, the international community faces the challenge of preventing a new era of heightened nuclear tensions. The Sarmat missile represents not just a technological achievement for Russia but a clear signal of its determination to maintain its status as a nuclear superpower in an increasingly multipolar world.

The Discovery of a Lost Musical MasterpieceThe discovery of a new work by Ralph Vaughan Williams has set the world alight this week. In a box in the archives of London's Morley College, Elaine Andrews came across a previously unknown Vaughan Williams song titled "Before the Mirror," which sets a Swinburne poem inspired by a Whistler painting. The manuscript's workings, its crossings-out and corrections, offer a fascinating insight into Vaughan Williams's creative process, revealing music of surprising tonal adventure and expressive ambiguity written shortly after his marriage in 1897.The Vast Landscape of Lost Musical WorksBut a single song pales into comparison compared to the musical riches that may be lying dormant in libraries, archives and lofts all over the world. One of the most significant musical finds of all time was the treasure-trove of manuscripts by Florence Price found in a derelict house in Illinois in 2009, which included her two violin concertos, Fourth Symphony and dozens of other pieces. This discovery revealed not only wonderful music, but also pointed to the priorities – and prejudices – of music historians.The Systematic Erasure of Female ComposersThat discovery revealed not only wonderful music, but also pointed to the priorities – and prejudices – of music historians. The discovery of previous unknown manuscripts by the most familiar composers – a single page of Mozart, an exercise by Beethoven, a sketch by Haydn – often happen because historians know where to look for ephemera of lives whose every artefact has been combed over for centuries. But that had not been the case for Price, or for other composers who have been musicologically marginalised. Their work is supposed to be "lost" simply because no one had been looking for it.Rediscovering Forgotten Female VoicesThat's why some of the deepest holes in musical history – works that we know composers wrote and that were performed in their lifetimes, but which their biographies say are now "lost" – are by female composers. Francesca Caccini wrote more than 13 stage works in her lifetime in 17th-century Italy, but only one survives today. Caccini's dozen other operas may currently be "lost," but have researchers been looking for them as assiduously as they search for a page by Bruckner or a letter by Mahler?The Case of Joseph BologneThe same goes for at least three complete operas by Joseph Bologne, who lived an extraordinary life in 18th-century France, as composer, violinist, orchestral leader, fencer and soldier, becoming a colonel in the revolution's only all-black regiment. But Bologne's legacy suffered the prejudices of a culture that reinstated slavery and which erased his contribution to the revolution and to musical society after his death in 1799. Now that Bologne's work is at last finding its place there must be renewed focus on recovering these vital "lost" operas from the oblivion that they never deserved.Legendary Lost Works We Can Only Dream OfMind you, there is also lost music whose absence has been known of for centuries – we can only dream of what could be. Bach's St Mark Passion and scores of his cantatas, Monteverdi's Arianna and other stage works, the dozens of quartets and sonatas that Brahms threw out as unworthy, or Sibelius's Eighth Symphony, likely consigned to the flames by Sibelius himself.New Leadership in Classical MusicIn other classical music news, the Royal Scottish National Orchestra has announced that Lithuanian conductor Giedrė Šlekytė is to be their next music director, succeeding Thomas Søndergård from the 2027 season. The appointment comes after just two projects: a well-received week of Mahler's First Symphony, and a subsequent recording session. As the RSNO's chief executive Alistair Mackie said: "When she joined us last year, her musical ideas and the way she works with players spoke for themselves. Giedrė gives the orchestra room to breathe and to play."

The LeadJennie Garth, known for her role as Kelly Taylor in 'Beverly Hills, 90210,' opens up about the psychological impact of early fame and how she found new purpose in her 50s. The 54-year-old actress, who felt 'stuck' and unfulfilled as her daughters grew up, has launched a podcast and book titled 'I Choose Me,' sharing her journey of self-discovery and the lessons learned from her decades in Hollywood.Finding Purpose at 50Approaching her 50s, Garth experienced a classic midlife crisis, questioning her path and purpose after noticing potential acting jobs becoming 'few and far between.' The deaths of her 90210 co-stars Luke Perry in 2019 and Shannen Doherty in 2024 intensified her sense of urgency, prompting her to share what she's learned with other women experiencing similar standstills. Her new venture, 'I Choose Me,' named after an iconic line from her character on the show, combines memoir and self-help as Garth reflects on her journey from teenage star to mature woman finding her voice.The Price of Early FameGarth candidly admits that her early fame 'screwed with her mind,' describing how she spent 20 years 'trying to keep her head above water.' Starting on the hit show at just 18, she felt developmentally 'held back from the realities of the world,' watching peers experience normal milestones while she was 'slammed into' fame. The experience left her questioning how her unusual path affected her relationships and personal growth, as she struggled to form normal connections while constantly being judged and typecast in the industry.Hollywood's Changing LandscapeThe actress reflects on the sexism she faced in the 90s, noting how young female actors were 'exposed to far more than they should' in terms of sexualization and discrimination. She recalls unspoken expectations about appearance and the pressure to conform to certain standards, including her own decision to get breast enhancement at 24. Garth also discusses how the industry typecast her and her co-stars, keeping them in a 'sort of Aaron Spelling-nighttime-soapy category' that limited their growth opportunities, despite the quality of their work.A New ChapterNow in her 50s, Garth feels she's finally 'caught up' developmentally and is embracing her age with greater wisdom and resilience. Through therapy and self-help, she's found a new voice and purpose, sharing her experiences to help other women navigate similar challenges. Her journey from teenage star to empowered woman reflects both the lasting impact of early fame and the potential for reinvention later in life, as she continues to work while also focusing on personal growth and helping others find their own path to self-acceptance.

The Lead: Carla Simón's Unique Approach to Family DramaFamily reunions in European arthouse cinema are almost always unhappy events, on a scale of strife that ranges from simmering resentment to spectacular score-settling. Carla Simón, however, has a rare gift: she makes you leave the cinema with renewed faith that having relatives and keeping in touch with them may actually be a wonderful thing.No film-maker working in Europe now is as capable of turning birthday gatherings, garden parties or poolside barbecues into thrillingly sprawling canvases of human virtue and vice as this 39-year-old rising star. From a riotous water fight in the Berlinale Golden Bear-winning farming drama Alcarràs to a foul-mouthed dinner table singalong in her new film Romería, Simón directs kinship meetings with the attention to detail that other film-makers may invest in action sequences or dance routines.The Event Details: Romería and the Journey to Self-DiscoveryAmong the tricks Simón employs, she explains, is to ensure her actors only read the script once before the camera starts rolling, so they have to improvise to fill the gaps. She takes her casts to parties, for walks and on shopping trips, and if there are disagreements on the way, so much the better. The ultimate secret sauce, though, is to ignore WC Fields's notorious advice and always work with children and animals."I never get bored of working with kids," she says. "When you are only working with adult actors, shooting becomes more like executing an idea that you have in your mind, and I think that is not interesting. With children, you always have this feeling that that things are going to happen in front of the camera by chance. It keeps things alive."Her new film Romería, meaning "pilgrimage" in Spanish, dives deeper into the story of the biological parents she barely got to know. Eighteen-year-old Marina travels to her relatives in Vigo, in north-western Galicia, purportedly to find the death certificate of her biological father, which she needs to study film-making in Barcelona. The initial reaction is warm, but family is a room with dark corners and locked closets.The Personal Journey: Aids, Loss and Family SecretsSimón's fascination with freewheeling scenes of family life was undoubtedly honed through her own biography. Born in Barcelona in 1986, her father died when she was three and her mother when she was six. Both of them succumbed to Aids. She was 12 when her adoptive mother told her that her parents had been infected with the autoimmune disease through their use of drugs.All of her first three films have been strongly autobiographical: Summer 1993 tells the story of a six-year-old girl who moves to an unspecified location countryside to live with her aunt after the death of her mother, while 2022's Alcarràs is specifically set in the Catalan peach-growing community of her adoptive family.In the film, a cache of letters written by her late mother opens up a portal to the time when her parents met and discovered love – for each other, the Atlantic Ocean and drugs. The letters, Simón explains, are real. "She wrote to her friends and family while she lived in Vigo. Her Catalan is full of mistakes, because teaching Catalan was banned under the Franco regime. But they are the most important thing that I have from my mother, because suddenly I can hear her talking."The Impact Analysis: Spanish Cinema and the Legacy of AidsSpanish cinema has a track record in making films where child actors take centre stage: Ana Torrent's spell-binding turn as a young girl obsessed with the Frankenstein tale in Víctor Erice's 1973 film The Spirit of the Beehive is considered an all-time great performance by a minor, and Simón describes it as "a very, very important film for me".During the transition period after Franco's rule, Madrid gave birth to la movida, a countercultural movement that celebrated lifestyles that had been banned under military rule. "All these kids who were raised under Franco and religious oppression, suddenly freedom arrived and they embraced it", Simón says. "They didn't think much about the future or the consequences of what they were experimenting with. And then the drugs came in."When we talk about this generation in Spain, people sometimes use words like shame and blame, but I feel that's really unfair: people like my parents just had bad luck.The Future Direction: Beyond Family in Simón's Next ProjectHalfway through Romería there is a stylistic shift, from the Eurorealism she favoured in her previous works toward something more magical-realist: there is a mysterious cat you might expect to encounter in a Miyazaki film, and an unforgettable dance number set to Vigo punk rocker's Siniestro Total's song Bailaré Sobre Tu Tumba ("I'll Dance on Your Grave")."These three films I've made are kind of a cycle, because they all talk about my family, adoptive and biological. But since I became a mother a few years ago, I feel that my place in the family changed. When you have kids you feel it's a new period in your life, so I feel like maybe doing something that has nothing to do with my family."Her next film, she confides, is going to be a flamenco musical.

The Incident at University of Central Florida Students at the University of Central Florida's 2026 graduation ceremony recently expressed their discontent with a speaker's comments on artificial intelligence (AI). Gloria Caulfield, a real estate development executive, was booed by the graduating class of 2026 when she likened the rise of AI to the next Industrial Revolution. Student Reactions and Concerns The crowd's reaction was immediate and loud, with Caulfield pausing, turning away from the podium, and throwing her hands up in the air. She responded by asking, "Woop, what happened?" and then nervously laughing, "OK, I struck a chord. May I finish?" The students' reaction reflects a broader anxiety about AI's impact on their future careers. A 2025 poll by the Institute of Politics at the Harvard Kennedy School found that a majority of recent college graduates view AI as a threat to their job prospects. The Impact of AI on Job Prospects The students' concerns are not unfounded. AI is transforming various industries, from graphic design to Hollywood and journalism. Tech CEOs have been slashing workforces, citing AI's ability to replace some jobs and boost efficiency. Industries outside Silicon Valley are also being affected by AI. Students are under pressure to choose majors that lead to AI-proof careers. The Future of AI and Education Caulfield's speech, despite the initial backlash, highlighted the importance of adapting to technological changes. She compared the current situation to when she finished college as the internet started taking off, noting that such technologies can be gamechangers for economic development and new businesses. The incident underscores the need for educational institutions to address AI-related anxieties among students. It also emphasizes the importance of preparing students for a future where AI will play a significant role.

Executive Overview: Syringe‑Smuggled Ants in NairobiThe Guardian article reveals that Nairobi is emerging as a nexus for the illegal trade of giant harvester ants, which are being hidden inside medical syringes to evade detection. This unconventional smuggling method highlights a growing challenge at the intersection of wildlife trafficking and public‑health safety.How Syringes Enable the Giant Harvester Ant TradeAccording to the report, traffickers exploit the small, sealed nature of syringes to conceal live ants during transport. The method allows large numbers of insects to be moved discreetly through customs and local markets, bypassing traditional inspection procedures.Scale of the Illicit Ant MarketWhile precise figures are not disclosed, the article notes a noticeable increase in seizures and police investigations related to ant smuggling in Nairobi.Local markets are reportedly offering the insects for purposes ranging from traditional medicine to exotic pet trade.Implications for Public Health and BiodiversityThe practice poses dual risks: the potential spread of ant‑borne pathogens to humans, and the ecological impact of removing a keystone species from its native habitats. Kenyan authorities are urged to strengthen bio‑security protocols to mitigate these threats.Future Outlook: Regulation and EnforcementExperts cited in the Guardian piece suggest that tighter customs inspections, public awareness campaigns, and regional cooperation will be essential to curb the syringe‑based trafficking network. Ongoing monitoring will determine whether Nairobi can shift from a trafficking hub to a model for effective wildlife‑trade enforcement.

The Trump-Xi Summit: A Pivotal Moment in US-China Relations Donald Trump's state visit to China this week – the first by the US president in nearly a decade – comes amid a time of geopolitical upheaval, a new and intractable conflict in the Middle East, and a sometimes rocky relationship between the world's two major superpowers. There is much for Trump and Xi Jinping to discuss, but a few key issues are likely to dominate the agenda. Five Critical Issues on the Summit Agenda The high-stakes meeting between the two leaders addresses several pressing matters that could reshape the global landscape: The Iran Conflict and Hormuz Strait Crisis Trump is eager for China to lean on Tehran to advance peace talks and reopen the strait of Hormuz. To now, Beijing has sat back and watched the US struggle against Iran, at least publicly. But with about half of China's crude oil imports passing through the strait, Xi does want the waterway unblocked. China knows its exports will suffer if a global recession results from an oil supply crisis. Complicating the picture, the US this week put sanctions on several Chinese firms accused of assisting Iranian oil shipments and supplying satellite imagery allegedly used in Iranian military operations, claims that Beijing denied. Trump's arrival comes after Iran's foreign minister, Abbas Araghchi, visited Beijing last week. Taiwan: The Flashpoint in US-China Relations Beijing is keen to push the US on Taiwan, with Trump saying he is prepared to raise the issue of arms sales to the island, which China claims as a breakaway territory despite never having ruled it. In December, Trump authorised an $11bn arms package for Taiwan, the largest weapons sale ever to the island, but no shipments have been made yet. Xi may seek changes in how the US refers to Taiwan. Ideally, from the perspective of Beijing, this would be a statement from Washington "opposing" Taiwan's independence rather than "not supporting" it. Taiwan will be watching closely. Just two weeks ago, China's foreign minister in a phone call with Marco Rubio urged the US to "make the right choices" on Taiwan. With Trump known to veer off script, John Kirby, a former US state department and Pentagon spokesperson cautioned: "They just have to be so extraordinarily precise when you're talking about Taiwan because, quite frankly, the stakes are enormously high." The AI Cold War: Technological Supremacy at Stake China and the US are locked into a race on artificial intelligence that is becoming something of a technological cold war. In April, the White House accused China of stealing US AI labs' intellectual property on an industrial scale, claims Beijing denied. Meanwhile, Beijing has been frustrated by Washington's reluctance to allow Nvidia to export its most powerful processing chips to China. In January, the White House said Nvidia could export its second most powerful chip, the H200, but no shipments have been sent yet. Analysts and ethics leaders hope Trump and Xi will discuss non-binding AI guidelines, including sharing information about AI misuse and safety, which are seen as critical guardrails amid the advent of AI weaponry and military adoption. Trade War: Rare Earth Minerals and Economic Leverage Trump has repeatedly threatened China over trade, imposing tariffs above 140% last year. But Xi held some cards of his own and did not fold. Instead, China blocked exports of its rare earth minerals and magnets to the US. Trump, finally, backed down. The US has depleted notable levels of its weapons arsenal in the war against Iran, with many weaponry components requiring critical minerals that are linked to supply chains dominated by China. China is expected to announce purchases related to Boeing airplanes, American agriculture and energy, US officials have said. In turn, Beijing wants the US to ease curbs on exports of advanced semiconductors. Beijing also wants to reduce barriers to investment in the US, and hopes to establish a Board of Investment to match the Trump-back Board of Trade. Fentanyl: The Drug War and Political Posturing Fentanyl is a key item on Trump's agenda this week, Politico reported, citing an administration official granted anonymity to preview the closed-door sessions. The US has long accused Chinese businesses of knowingly supplying the chemical precursors to Mexican cartels who use them to make the drug. Trump knows that being seen to press China hard over fentanyl and precursors plays well with his Maga base. But Trump lost important leverage on the fentanyl front when China defied his tariffs threats. In March, the US and China clashed over fentanyl and trade at a UN drugs meeting. China wants to be removed from the state department's annual list of "major drug transit or illicit drug producing countries", due to be updated in September.
