The Energetic Cost of Pollen Collection Bees use as much energy collecting pollen through “floral buzzing” as they do taking off in flight, a study shows. Scientists have found the vibrations bumblebees use to shake pollen loose from flowers are among the most exhausting behaviours they perform, forcing bees to “carefully choose” which flowers are worth visiting. The Study's Findings The study, released by the Royal Society, is the first to directly measure the energy cost of floral sonication, or “buzz pollination” – where bees vibrate flowers to extract pollen. Natacha Rossi, a University of Sussex research fellow who led the study, said: “As nectar availability shifts due to climate change or habitat loss, the energetic demands of pollination could influence bee behaviour and, ultimately, where bees forage and which plants they pollinate. The Data Analysis Using lasers and respirometry equipment to monitor three colonies of buff-tailed bumblebees, researchers discovered that a single “buzzing event” required about the same amount of energy as a flight take-off. Because buzzing can last longer, the total drain on energy can be even greater. The metabolic rate of a floral buzzing bee is more than 30 times higher than its resting metabolism, according to the study, making the process among its most energetically demanding behaviours. The Impact Analysis The researchers warned that declining nectar supplies caused by climate crisis and habitat destruction could intensify the strain on pollinators. Prof Mario Vallejo-Marin, at Uppsala University, said: “We long suspected that buzz pollination was an energetically expensive affair. We can now put a number to it and begin making quantitative predictions of how it could affect the ecology and evolution of bees and buzzpollinated flowers.” The Prediction The study points out that the energetic drain on the bee does not stop when the pollination stops. According to the paper, after the bee vibrates the pollen loose, it must engage in a “grooming and pollen-packing phase”. This grooming takes even more energy. The bee then has to force a high-power take-off to carry its new, heavier load away, making the whole process a demanding two-phase sequence.

Breakthrough Cancer Drug Reveals Hidden TumorsA smart drug that stops cancer cells "hiding" from treatment can shrink tumours by at least 30% in six of the world's most common forms of the disease, according to early trial results. While immunotherapy treatments have improved survival rates for many patients, their effectiveness can stall or fail when tumour cells hide and then spread.How the Smart Drug WorksResearchers in Oxford have developed a drug designed to stop cancer cells concealing themselves from the immune system, allowing immunotherapy treatments to identify and destroy them. In a trial spanning the UK, France, Spain and Australia, 83 patients with cervical, bladder, liver, bowel, lung or head and neck cancers were given the experimental drug, GRWD5769, alongside the immunotherapy treatment cemiplimab.The smart drug was able to remove "invisibility cloaks" from tumour cells, exposing them to the parts of the immune system that attack infections and diseases. This allowed the cemiplimab immunotherapy to pinpoint and destroy the cancer.Trial Results Across Cancer TypesResearchers, led by the Christie NHS foundation trust in Manchester, England, found that tumours shrank in 26 patients. Of those, 15 experienced tumour reductions of at least 30%. All participants had previously failed to respond to treatment, and most had no options left when they joined the study.GRWD5769 was shown to shrink tumours in all six cancer types included in the trial. The drug halted progression of the disease for at least six months in 18% of cervical cancer patients, 32% of liver cancer patients, 36% of bladder cancer patients, 38% of those with neck and head cancer, and more than half of bowel (51%) and lung (55%) cancer patients.Significance for Cancer TreatmentImmunotherapy enlists T-cells – immune system cells that attack infections and diseases – to hunt and destroy cancer. Although it has revolutionised cancer care, it fails in about two-thirds of patients. This is because immunotherapy struggles when tumours hide from the immune system.Tumours can evade the immune system by manipulating an enzyme called ERAP1 (endoplasmic reticulum aminopeptidase 1). By altering this enzyme, cancer cells can hide from a patient's T-cells. GRWD5769 solves this problem by inhibiting ERAP1, which removes cancer's invisibility cloak and makes tumour cells visible to T-cells that could not previously find them.Future Outlook for Cancer TreatmentThe findings were presented at the American Society of Clinical Oncology's annual meeting in Chicago, the world's largest cancer conference. Prof Fiona Thistlethwaite, the principal investigator, noted: "For a drug that is given as a tablet, this is very impressive. It's early days, and we need further studies, but this is a new drug with a new mechanism that clearly helps immunotherapy perform more effectively."The tablets, which were developed by Oxford-based Greywolf Therapeutics and were tolerated well by patients. The trial remains ongoing, with a larger study planned. Cancer Research UK's research information lead, Dr Samuel Godfrey, noted: "Immunotherapy has transformed treatment for some cancers but it doesn't yet work for everyone. This trial seems to show how this new drug could make immunotherapy more effective, including in some cases where immunotherapy had previously failed."

On Monday morning, a jury in Oakland, California, delivered a decisive victory to Sam Altman and OpenAI, dismissing Elon Musk's $150 billion lawsuit against the AI giant and its top executives. The Verdict in Oakland: A Procedural Victory for Altman The nine-member jury found that Musk had waited too long to bring his claims, ruling that the statute of limitations had expired before he filed the lawsuit in 2024. US District Judge Yvonne Gonzalez Rogers accepted the finding and dismissed the case, preventing the trial from addressing the core question of whether OpenAI betrayed its nonprofit mission. Verdict: Musk lost on procedural grounds (statute of limitations). Deliberation: Jury deliberated for less than two hours. Outcome: Case dismissed; no ruling on mission betrayal. The $150 Billion Dispute and OpenAI’s Valuation The trial centered on a financial and structural clash between two of Silicon Valley’s most powerful figures. While Musk sought to recover $150 billion, the case highlighted the immense scale of OpenAI's commercial success, which is reportedly valued at over $800 billion. Legal Claim: Musk sought $150 billion for alleged enrichment. Company Valuation: OpenAI valued at more than $800 billion. Timeline: Founding (2015) vs. Resignation (2018) vs. Lawsuit (2024). Why the Ruling Reshapes the AI Landscape This ruling removes a major legal threat for OpenAI at a pivotal moment. The company is deepening commercial partnerships and moving toward a potential public offering, a process that was previously clouded by Musk's legal challenges. However, the dismissal leaves the broader debate on AI governance unresolved. The trial never addressed critical issues such as transparency, data extraction, or how to govern superintelligent AI systems. The Road Ahead: Appeals and Unresolved Questions Musk has announced his intention to appeal, ensuring the feud will continue. The ruling clears the path for OpenAI's commercial expansion but does not settle the philosophical conflict over whether AI should prioritize profit or public benefit.

Decades of Cross-Border Conflict: An OverviewThe historical narrative of Israel and Lebanon is deeply intertwined with recurring cycles of military escalation. From the late 20th century to the present day, the shared border has been a flashpoint for regional tensions. This complex history of invasions, occupations, and retaliatory strikes provides essential context for understanding the enduring instability in the Middle East and the challenges of establishing lasting peace.Tracing the Roots of Military EngagementsThe history of Israeli military involvement in Lebanon can be categorized into several distinct phases, each driven by specific security concerns and regional dynamics.1978 Operation Litani: Israel's first major incursion into southern Lebanon, aimed at pushing Palestinian Liberation Organization (PLO) forces away from the border.1982 Lebanon War: A massive invasion that reached as far as Beirut, resulting in the expulsion of the PLO but leading to an 18-year occupation of southern Lebanon.1993 and 1996 Operations: Major military campaigns (Operation Accountability and Operation Grapes of Wrath) designed to neutralize the growing threat of Hezbollah, which had emerged during the Israeli occupation.2006 Lebanon War: A 34-day conflict triggered by a cross-border raid by Hezbollah, resulting in heavy casualties and infrastructure damage on both sides.The Human and Economic Toll of Prolonged InstabilityThe repeated conflicts have left an indelible mark on both nations, though the economic and infrastructural impact on Lebanon has been disproportionately severe. Decades of warfare have stunted Lebanon's economic development, repeatedly destroying critical infrastructure. The human cost is staggering, with tens of thousands of casualties and the displacement of millions of civilians over the years. For Israel, the constant threat of cross-border rocket fire has necessitated immense defense spending, including the development of advanced defense systems like the Iron Dome.Shifting Geopolitical Dynamics in the LevantThe historical pattern of conflict has fundamentally shaped the geopolitical landscape of the region. The power vacuum created by previous invasions allowed non-state actors, particularly Hezbollah, to consolidate political and military power within Lebanon. This dynamic complicates traditional diplomatic solutions, as any future negotiations must account for the complex web of proxy interests involving regional powers like Iran and global actors. The border region remains heavily militarized, serving as a microcosm of the broader Middle Eastern struggle for influence.The Trajectory of Future Border RelationsLooking ahead, the historical precedent suggests that without a comprehensive diplomatic framework, the cycle of escalation is likely to persist. The reliance on military deterrence has historically provided only temporary calm. Future stability in the region will depend on addressing the underlying political grievances, establishing clear rules of engagement, and finding a sustainable balance of power that respects the sovereignty of both nations while ensuring mutual security.

The Lead: Qatar's World Cup JourneyFour years on from their FIFA World Cup debut on home soil, Qatar are gearing up for a new "dream." The reigning – and back-to-back – Asian champions head to the June 11-July 19 football tournament in North America, having qualified outright for the first time in the Arab nation's history.The Event Details: Qatar's Group B ChallengeMaking their way to the showpiece after three successful rounds of qualifiers, the Qataris find themselves in an interesting, and potentially inviting, Group B, facing Switzerland, Canada and Bosnia and Herzegovina. The prospect of reaching the knockout stages for the first time appears a realistic target.The Data Analysis: Opponent Rankings and Historical ContextIn Switzerland and Bosnia and Herzegovina, Qatar face two strong teams from Europe. Switzerland are making their 13th appearance at the finals, having reached the knockouts in each of their last three campaigns. The 19th-ranked Swiss, whose best finish has been the quarterfinals on three occasions, are frontrunners to finish as table toppers of Group B.At number 65 in the FIFA rankings, Bosnia and Herzegovina are placed lower than Qatar, but it would be foolish to write them off based on that alone. Returning to the World Cup for the first time in 12 years, Bosnia and Herzegovina pulled off one of the biggest upsets of the qualifiers when they knocked out four-time world champions Italy on penalties.Qatar can expect a tough challenge from both European teams, but the two-time Asian champions could take a point or three against Canada, the number 30 team in the world and the co-hosts of the tournament, alongside the United States and Mexico.The Impact Analysis: Lopetegui's Philosophy and Qatar's DevelopmentTalking to Al Jazeera ahead of the tournament, Qatar's Spanish coach Lopetegui said the team achieved a "big goal" by qualifying for the 48-team World Cup on merit. While the achievement is momentous for all of Qatar, it also holds special importance for Lopetegui, who is heading to his first World Cup as a coach.Lopetegui, who took over in May 2025, admitted that while Qatar are weaker than their opponents, there is no shortage of ambition among his players. "Each moment that you have at the World Cup is top," he added. "So in this case, you analyse each country, talking about each player and which competition they are playing… you're playing against the best players in the world. Now, we have to be ready and prepare ourselves to be competitive."Qatar's squad remains built around a domestically developed core shaped through the Aspire Academy system that underpinned their rise over the past decade. Many of the squad have progressed through the same development pathway, giving Qatar continuity and cohesion, though questions remain over whether a group drawn largely from the domestic league has the depth and experience required to compete consistently with elite opposition.The Prediction: Qatar's Path to the KnockoutsQatar have a chance, even if it is a slim one, of reaching the knockouts. Their best bet for collecting points is against Canada. Should Qatar beat Canada, they will have three points, which should be enough to qualify for the round of 32 as one of the eight best third-placed teams.If Qatar draw all three games – which is less likely than the above scenario – even that could see them through to the knockouts for the first time in history. Simply put, the game against Canada is a must-win for Qatar if they dream of a deep run.Key Players to WatchIf Qatar are to crush Canadian hopes in Vancouver, the Gulf country will have to rely on the goal-scoring prowess of striker Almoez Ali, Qatar's all-time marksman with 60 goals, and star winger Akram Afif, the two-time Asian player of the year and the team's main source of creativity.Having played every minute of Qatar's last World Cup campaign, Afif shares the record for most appearances at the tournament (three) alongside defenders Boualem Khoukhi and Abdelkarim Hassan. Captain Hassan Al-Haydos, who came out of retirement in June 2025 at Lopetegui's request, is another fan favourite and holds the record of being Qatar's most-capped player with 188 appearances.Qatar's World Cup 2026 ScheduleAll times in local timeJune 13, 12pm PDT (19:00 GMT) – Qatar vs Switzerland – Santa Clara, California (US)June 18, 4pm PDT(23:00 GMT) – Canada vs Qatar – Vancouver (Canada)June 24, 12pm PDT (19:00 GMT) – Bosnia and Herzegovina vs Qatar – Inglewood, California (US)

Sabalenka's Shocking Exit Aryna Sabalenka’s bid for a first French Open title has been left in tatters after she fell apart in a bizarre defeat by Russian 25th seed Diana Shnaider in the quarterfinals. The world number one led by a set and a double break before exiting the tournament on Wednesday in a blaze of unforced errors, collapsing to a 3-6, 7-5, 6-0 loss in blustery conditions on Court Philippe-Chatrier. The Match in Focus Shnaider will face Polish qualifier Maja Chwalinska in the semifinals on Thursday, with Marta Kostyuk or Mirra Andreeva awaiting the winner in Sunday’s final. “Well honestly, I’m speechless, I’m super happy. Obviously tough conditions with the wind,” said the 22-year-old Shnaider after beating a top-10 player for only the second time in her career. “First time playing Aryna, so definitely a lot of nerves, and I feel the first set was trying to adjust to her game.” Analyzing Sabalenka's Performance Sabalenka was the only Grand Slam champion left in either the men’s or women’s singles draws at Roland-Garros, but belied that status by making a whopping 57 unforced errors. Shnaider was playing in her first major quarterfinal, but now finds herself a strong favourite to reach the final heading into her last-four tie against world number 114 and fellow left-hander Chwalinska. What's Next “Definitely super happy I managed to finish on a good note rather than start on a good note. Definitely a special tournament for me here,” added the Russian. “It’s going be a lefty battle, so I’m looking forward [to the semifinal].”

The Return of Joy in Women's FootballIn an era where football has become increasingly serious and analytical, the World Sevens Football tournament offered a refreshing reminder of the sport's primary purpose: fun. For three sun-kissed afternoons by the Thames, this end-of-season seven-a-side women's football tournament provided the perfect antidote to the depressingly serious elements of the modern game, focusing on goals, laughter, and entertainment rather than VAR controversies or financial fair play regulations.The World Sevens Tournament: A Celebration of FootballThe third edition of World Sevens Football, featuring eight English teams, culminated in an 11-goal thriller final won by Chelsea. The tournament format allowed flair players such as Manchester United's Melvine Malard and Jess Park to thrive, showcasing their stepovers and lethal finishing. Chelsea's Aggie-Beever-Jones emerged as the top scorer with eight goals, demonstrating her clinical finishing ability against defenders. Teams also embraced the entertainment aspect with meticulously prepared walk-on routines, ranging from the hilarious to the bizarre. Everton's players pretended to give birth, Chelsea manager Sonia Bompastor was carried onto the pitch by her players, and Manchester United's head coach Marc Skinner made an entrance in a dressing gown. Even the referees participated in the festivities with their own walkout routine.Financial Impact and Fan EngagementThe tournament delivered significant financial benefits to women's football, with $500,000 (£372,000) awarded to the winners. This injection of capital is particularly valuable for a sport that often struggles for funding. Fan engagement was equally impressive, with a sold-out crowd of 3,000 attending Saturday's final. One clip on Dazn's Instagram featuring Beever-Jones's amusing walk-on garnered over 11 million views, demonstrating the tournament's ability to expand the reach of women's football beyond traditional audiences. Jennifer Mackesy, a co-founder of World Sevens Football, expressed her delight with the fan response: "The response from fans in London has blown us away."Challenging Conventions in Women's FootballThe tournament's entertainment-focused approach sparked debate within the women's football community. Some observers, perhaps mistaking the event for the World Cup final, expressed annoyance on social media about players not acting in a "serious" manner. One X user wrote: "Organisers of this have genuinely set them back years." Another commented: "Unfortunately, women's football won't ever be taken seriously." Even respected figures in the women's game were critical, with former Everton women's manager Andy Spence responding to a viral video of Everton's players acting out a mock funeral by writing: "What is going on? The Women's game has made such progress but these 'tournaments' and the narrative around them are threatening the integrity & hard work people have put in to make the Women's game be accepted by a wider audience. Please stop. Embarrassing."The Future of Entertainment in Women's FootballDespite the criticisms, the World Sevens Football tournament demonstrated several crucial benefits for women's football. It broadened teams' reach through social media exposure, brought much-needed investment into the sport, and attracted new fans. The tournament also provided light relief to players after a gruelling season, allowing them to express themselves in football's "purest form." While the event is not without its challenges—inequitable facilities for different teams and injuries to players like West Ham's Tuva Hansen and Manchester United's Phallon Tullis-Joyce—the engagement from broadcast partners Sky Sports and Dazn suggests this format has a bright future. As women's football continues to grow, events like the World Sevens may play an important role in diversifying the sport's appeal and finding new ways to engage audiences while maintaining the competitive spirit that makes football compelling.

The Art Capital's Annual CelebrationWith hundreds of world-class galleries, thousands of stunning exhibitions, and countless talented artists, London has a serious claim to being the art capital of the world. Despite challenges like sky-high rents making it difficult for artists to survive and galleries closing at an unprecedented rate, London Gallery Weekend enters its sixth year as a celebration of the city's vibrant art scene.A Weekend of Free Art ExperiencesLondon Gallery Weekend brings together the city's biggest, brightest, and best galleries for a weekend-long art party. The event features talks, walk-throughs, performances, poetry readings, and gigs across the weekend, with galleries staying open late. Best of all, admission to everything is free. While not quite at the level of Berlin Gallery Weekend, which is a genuine international event, London's celebration makes a persuasive statement about what the city's galleries have to offer.Global Art in Every CornerThe exhibitions span the city, featuring artists from every corner of the globe: South American photography, German conceptualism, African portraiture, American minimalism, British satire, and more. Works by giants of modern art share space with shows by little-known upstarts, all taking place in venues ranging from fancy galleries that look like spas to tiny experimental project spaces that feel like hip squats.Curated Routes for Art EnthusiastsFor those unsure what to see, the event offers routes conceived by cultural figures including producer Kelly Lee Owens and fashion designer Erdem Moralıoğlu. To help navigate the dozens of exhibitions, here are 10 must-see art delights that showcase the diversity and quality of London's contemporary art scene.Francis Picabia: Expanding HorizonsFrom early landscapes to later abstracts, this show takes viewers on a journey through the many twists and turns of this hugely important French modernist's wild career. It's basically a mini-Tate retrospective, but free. The gallery is also hosting a literary salon inspired by Picabia – as well as their Roni Horn show next door – on Friday evening.Location: Hauser & Wirth, MayfairDuration: Until 1 AugustAnne Imhof: CitizenStern heavy-metal conceptualist Anne Imhof returns to Sprüth Magers for more gothic explorations of the body. This show features frenetic scratchy paintings, a morose new film, and an installation made of crowd barriers. It's all about control, manipulation, death. It's not light or fun – but it is good.Location: Sprüth Magers, MayfairDuration: 5 June to 1 AugustDominic Watson: Vinegar and PissThis brilliantly weird English artist has filled a south London gallery with a massive galleon made from reclaimed children's playhouses. Step inside and you'll find papier-mâché sculptures of vomiting heads and disembodied limbs in an acerbic, silly, surreal takedown of the UK's descent into intolerance.Location: The Sunday Painter, VauxhallDuration: Until 11 JulySavannah Harris: Gloria'sThis neat, experimental gallery up in north-west London has been transformed into an upmarket cafe named Gloria's – all expensive lattes, cream-coloured walls, and red logos (sound familiar?). Harris is using the space as a chance to show work by outsider artists, alongside her own paintings, in a sharp dig at gentrification and the erosion of opportunities for artists and community social spaces.Location: Harlesden High StreetDuration: 5 June to 26 JulyKeith Piper: Provocative PerspectivesKeith Piper presents thought-provoking work that challenges conventional narratives and explores complex themes of identity and representation. As a significant figure in British contemporary art, Piper's exhibition offers critical insights into social and political issues through his distinctive visual language.Location: Various galleries across LondonDuration: Throughout Gallery Weekend
