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 However, in most high-income countries, a rapid rise in the prevalence of obesity has been replaced by a slower increase, a plateau, or a potential decline.Regional Variations in Obesity PrevalenceThe rate of growth in obesity is slowing in adults in the US and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

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.

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.

Executive Summary: Trump’s Unexpected EndorsementOn 13 May 2026, former U.S. President Donald Trump publicly declared his backing of Iraq’s prime‑minister‑designate Ali al‑Zaidi. The move, coming amid a fragile coalition government in Baghdad, signals a potential shift in Washington’s approach to Iraqi politics.Political Context: Why Trump Chose Ali al‑ZaidiTrump’s decision appears rooted in three observable factors:Geopolitical alignment: Al‑Zaidi’s platform emphasizes stronger security ties with the United States.Economic incentives: The designates’ openness to U.S. investment in oil and reconstruction projects aligns with Trump’s “America First” economic narrative.Regional stability: Supporting a leader perceived as capable of curbing Iranian influence fits Trump’s broader Middle‑East strategy.Fiscal Implications: Aid and Investment FiguresNo new financial commitments were announced alongside the endorsement. However, existing U.S. assistance to Iraq—approximately $1.5 billion annually for security and development—remains a baseline for any future cooperation under al‑Zaidi’s administration.Regional Ripple Effects: Shifts in Iraqi Power DynamicsThe endorsement could accelerate al‑Zaidi’s consolidation of power, pressuring rival factions to negotiate. Neighboring states, particularly Iran and Saudi Arabia, may reassess their diplomatic postures, potentially leading to a recalibration of proxy activities within Iraq.Looking Ahead: What Trump’s Backing Means for Iraq‑US RelationsAnalysts anticipate three possible trajectories:Enhanced bilateral cooperation: A Trump‑endorsed government may secure more favorable terms for U.S. firms in oil and infrastructure.Political volatility: Opposition groups could mobilize against perceived external interference, risking protests or parliamentary deadlock.Strategic realignment: A stable, U.S.-friendly leadership might prompt Washington to increase its diplomatic footprint, including a potential revival of a U.S. embassy advisory team.In the coming months, the durability of Trump’s support—and its translation into concrete policy—will be a key barometer for Iraq’s political stability and the broader U.S. strategy in the Middle East.

The LeadIsraeli authorities have demolished Palestinian-owned shops in East Jerusalem, clearing the way for a road that will connect Israeli settlements with the city center. The operation, conducted on May 13, 2026, has drawn immediate condemnation from Palestinian officials and international observers who view it as further entrenchment of the Israeli occupation.Demolition Clears Path for Settlement-Linked InfrastructureThe bulldozing operation targeted commercial establishments in the Sheikh Jarrah neighborhood, a flashpoint area in East Jerusalem where Palestinian residents have faced repeated displacement pressures. Israeli officials stated the demolitions were necessary for "security and infrastructure development," though Palestinian representatives characterized the move as an illegal land grab aimed at expanding Israeli settlements.The new road is designed to improve connectivity between Israeli settlements in the West Bank and Jerusalem proper, effectively bypassing Palestinian neighborhoods and further integrating the settlements into the Israeli infrastructure network.Economic Impact on Palestinian CommunityThe demolition of Palestinian shops represents a significant economic blow to the local community, with estimates suggesting the loss of dozens of businesses that served both residents and visitors. Local shopkeepers, many of whom have operated in the area for generations, reported receiving minimal compensation if any at all.Economic analysts note that such demolitions contribute to the fragmentation of the Palestinian economy in East Jerusalem, with cumulative effects including increased unemployment, reduced commercial activity, and further displacement of Palestinian residents from areas targeted for settlement expansion.Escalating Regional TensionsThe operation comes at a particularly sensitive time in the Israeli-Palestinian conflict, with recent escalations in violence and diplomatic tensions. Palestinian officials have condemned the move as a violation of international law and a further obstacle to peace negotiations.International observers have raised concerns about the broader implications of such actions, which they argue undermine the two-state solution by creating irreversible facts on the ground. The European Union and several Arab nations have issued statements expressing their disapproval and calling for a halt to settlement-related activities.Future Outlook and Potential ConsequencesFollowing this demolition, tensions in East Jerusalem are likely to remain high, with potential for increased protests and clashes between Palestinian residents and Israeli security forces. The incident may also impact already fragile relations between Israel and neighboring Arab states.Legal challenges are expected from Palestinian rights groups, though previous cases have rarely resulted in reversals of Israeli demolition orders. The international community may face increased pressure to take concrete measures against settlement expansion, though past experience suggests diplomatic responses will likely remain limited to verbal condemnation.

New research from the International Data Center Association (IDCA) reveals that datacentres are now responsible for roughly 6% of electricity consumption in the United Kingdom and the United States, intensifying public and political scrutiny over the sector’s rapid energy growth.Datacentre Power Demand Hits 6% of UK and US GridsThe study notes a 15% worldwide increase in datacentre electricity use over the past two years, driven by the surge in AI workloads and internet traffic. Annual global investment in new facilities is approaching $1tn (£740bn), equivalent to nearly 1% of the global economy. In the UK, datacentre electricity share has risen to 5.9%, while the US sits at 6%, far above the global average of 2%. Smaller nations such as Singapore and Lithuania face even higher pressures, with datacentres consuming 19% and 11% of their national grids respectively.Financial and Energy Metrics Highlight Rapid GrowthGlobal investment: ~$1tn in 2025UK grid‑connection queue: grew 460% in H1 2025US “zombie” services: account for 13% of datacentre load, equating to over 3 GW of wasted powerProjected UK demand: could quadruple by 2030These figures align with the International Energy Agency’s estimate that global energy use by datacentres rose 17% in 2025, outpacing overall electricity demand growth of 3%.Community Pushback and Policy Implications Across NationsThe IDCA warns that once a country’s datacentre footprint reaches the 5%‑6% threshold, “significant community and political pushback” becomes inevitable. In the UK, activists and groups such as Greenpeace UK have warned of an “unchecked AI boom” leading to higher energy bills, water‑stress, and renewed reliance on fossil fuels. The report calls for:Greater transparency from tech firms on future datacentre plansMandatory environmental impact assessmentsA ban on new polluting power plants dedicated to AI workloadsAdditionally, the study highlights emerging security concerns, noting that recent attacks on datacentres in the Middle East have underscored the need for integrated cyber‑physical protection strategies.Outlook: Regulation, Transparency, and Security Challenges AheadLooking forward, the IDCA predicts that pressure will mount for:Stricter national grid connection policies to curb the 460% surge in pending requestsIndustry‑wide standards to eliminate “zombie” services and improve energy efficiencyCoordinated security frameworks that address both cyber threats and physical vulnerabilitiesIf policymakers act swiftly, the sector could mitigate its environmental footprint while sustaining the growth of AI and cloud services. Failure to do so may trigger broader societal resistance and accelerate regulatory clampdowns.

The Risks of Sharing Secrets with AI Chatbots The ongoing legal battle between Elon Musk and OpenAI has taken a dramatic turn with the revelation that OpenAI's president, Greg Brockman, kept a diary during the company's founding years. This diary has become central to the case, with one heavily cited extract reading: "Financially what will take me to $1B?" Another scrutinized passage states: "It'd be wrong to steal the non-profit from [Musk]. to convert to a b-corp without him. that'd be pretty morally bankrupt. and he's really not an idiot." The Implications of Chatbot Conversations in Court As millions of people use tools like ChatGPT as a digital confession box or therapist, experts warn that these conversations can be admissible in court. In fact, a lawyer told Axios that "within the next decade," the diary equivalent will be standard discovery in every major executive litigation in the country. This means that you shouldn't trust a chatbot with your secrets, as conversations with AI are not always private and may be retained indefinitely and shared with other humans. The Privacy Concerns of Chatbot Conversations Most chatbot conversations are not private, and users should be wary about sharing sensitive information. A recent case involving a former NFL player who allegedly asked ChatGPT for help after killing his girlfriend demonstrates the potential risks. As David Friedberg, a co-host of the All-In podcast, said: "You're just sitting here at home, like, let me write about the crime I'm committing … and by the way, let me never delete it." The Future of AI and Confidentiality As AI technology continues to evolve, it's essential to consider the implications of sharing sensitive information with chatbots. While chatbots like ChatGPT may seem like a safe space to share your thoughts, they are not a substitute for human therapists or lawyers. In fact, they can be a liability in court. As the use of AI chatbots becomes more widespread, it's crucial to prioritize confidentiality and consider the potential risks of sharing secrets with AI.

The Deadly Israeli Drone Strikes Three Israeli drone strikes on cars on a major highway linking Beirut to southern Lebanon have killed at least eight people, including two children, Lebanon’s Ministry of Health reported. A photograph of the bombed cars shared by Lebanon’s National News Agency following the attacks on Wednesday in the Jiyeh area, some 20km (12 miles) south of the Lebanese capital, showed the vehicles severely damaged, their exteriors charred and torn apart. Escalating Conflict and Humanitarian Crisis Al Jazeera’s Zeina Khodr, reporting from Tyre in southern Lebanon, said the “conflict is only escalating”. “It is a conflict that is taking a high toll on the civilians who live in these areas,” she said. Lebanon and Israel are expected to hold a new round of direct negotiations in Washington on Thursday, brokered by the United States. Hezbollah, which has been launching attacks on northern Israel and on Israeli troops who have entered and occupied a section of southern Lebanon, says it opposes the negotiations in the US. The Humanitarian Toll On Wednesday morning, the Israeli military issued forced displacement orders for the residents of Meiss el-Jabal, Yanouh, Burj Shemali, Hula, Debl and Aabbasiyyeh, warning that it will soon act against these six southern Lebanese villages “forcefully”. Anyone who remains “endangers their life,” the military said, warning residents to move at least 1,000 metres (0.6 miles) away to “open areas”. After this new round of forced displacement orders – which have been happening almost daily in the past week – Al Jazeera’s Khodr said one of the few remaining hospitals in the area was in the displacement zone. At least 100,000 people still live in the district of Tyre. 13 people were killed in attacks on towns in the south on Tuesday. Two Lebanese Civil Defence paramedics were among the dead. At least 380 people have been killed during the truce. The total death toll since the Israeli invasion and bombardment began on March 2 is more than 2,800. 108 emergency medical services and healthcare workers have been killed in Lebanon during the war. The Future Outlook “All of this is having a huge impact here on the communities in southern Lebanon,” Al Jazeera’s Obaida Hitto said from Tyre. “And there is a growing humanitarian crisis, with over a million people displaced.”
