The Meteorite Impact: A Cataclysmic Event What would it have been like to have lived through the meteorite impact that wiped out the dinosaurs 66m years ago? Writing in the Conversation, Michael Benton, of the University of Bristol, and Monica Grady, of the Open University, describe in vivid detail how it might have felt. The Initial Blast and Its Immediate Effects The first sign that something was amiss would have been a new star visible for about a week before the event. Upon its arrival, all living creatures near the impact site would have seen the bright fireball, heard its crackling noise and experienced a sonic boom before being swiftly incinerated. The Global Devastation Five minutes later, 100-metre-high mega tsunamis rolled across the Gulf of Mexico and, combined with the overheating, earthquakes, hurricanes and fires, wiped out everything within a 1,200-mile (2,000km) radius. The Long-Term Consequences Dinosaurs roaming forests on the other side of the world were still oblivious, but not for long. Within an hour, dust had circled the planet and skies had darkened. Within a day, global temperatures were dropping, and by the end of the week the world was 5C cooler. A ferocious winter lasted for more than a decade, eliminating about 75% of all species. A Warning for the Future Our ancestors were some of the lucky survivors but, sadly, Benton and Grady suggest our penchant for burning carbon is setting the scene for a similar scale of planetary catastrophe.

The Escalating Cost of Russia's War in UkraineEvidence of Russia's poor performance in its war in Ukraine, both militarily and economically, has been mounting over the past week. The US Defence Intelligence Agency (DIA) has confirmed earlier assessments that Russia has lost territory it previously occupied in Ukraine, while Ukraine has managed to reclaim approximately 400 square kilometers in and around Dnipropetrovsk – more territory than at any time since late 2022.Russia's Military Setbacks and Economic StrainRussia has still made a net territorial gain in 2026, but its advance is slowing down dramatically. According to the Institute for the Study of War (ISW), a Washington-based think tank, Russia advanced by a net 104 sq km between January 1 and May 26, 2026, compared to its seizure of 1,619 sq km during the same period last year.Ukrainian President Volodymyr Zelenskyy reported that Russian casualties had increased to 145,000 this year, of which 86,000 were killed and 59,000 troops seriously wounded. Ukraine's Defence Minister, Mykhailo Fedorov, highlighted that this meant 179 Russian losses per square kilometre of advance, compared to 67 last year – a rate higher than what Russia is currently able to replace through recruitment.Russia's war is also becoming increasingly difficult to finance. Having exceeded its entire 2026 budget deficit allowance by April, and depleted its foreign exchange reserves, Russia has been drawing down gold reserves at an unprecedented pace. According to its Central Bank, Russia has sold 27.9 tonnes of its gold reserves this year, worth more than $4bn, leaving reserves at their lowest since the beginning of the full-scale invasion in February 2022.Shifting Battlefield Dynamics and StrategiesThe DIA attributed Ukraine's territorial gains to Russia losing access to Starlink satellite services used for targeting and counter-battery fire. Ukraine attributes its success to its strategy of interdicting Russian logistics through mid-range drone and artillery strikes, which Fedorov described as a programme called "Logistical Lockdown" designed "to scale up middle-strike and systematically destroy Russian capabilities at the operational depth."This Ukrainian tactic has prevented reinforcements of men and equipment from reaching the frontlines, diminishing Russia's superiority in depth of resources and mass. The effectiveness of this strategy was demonstrated when Kherson occupation governor Vladimir Saldo restricted movement along the M-14 highway connecting Mariupol, Berdyansk and Melitopol, due to the number of vehicles being struck there.On the defensive front, Ukraine received a significant boost when Sweden announced it would donate 16 Gripen warplanes to Ukraine, which would also purchase an additional 20 through the EU's Ukraine Support Loan in a deal worth $2.9bn. Zelenskyy noted that "Gripen fighters with appropriate weapons, in particular Meteor missiles, which destroy targets at a distance of more than 200 kilometres, will help us push back Russian aircraft" against the approximately 3,000 Russian glide bombs dropped weekly.Simultaneously, Ukraine continued its long-range strikes on the Russian oil economy, which funds the war. On May 23-24, Ukraine struck oil depots and terminals at Novorossiysk and Tamanneftegaz on the Black Sea, as well as military and industrial sites including the Metafrax Chemicals plant in Perm and the Taganrog Airbase in Rostov.Russia's Response and Escalation TacticsIn response to Ukrainian advances, Russia pursued its own aerial tactic of striking Kyiv through massive combined attacks of drones and missiles. On May 24, Russia launched 600 long-range drones and 90 missiles against Kyiv and surrounding areas, including 36 ballistic missiles. Ukraine managed to shoot down 91 percent of the drones and 81 percent of the cruise missiles, though those that hit damaged government buildings, museums, and a market, injuring at least 87 people and killing two.Russia framed these attacks as retaliation for what it described as a terror attack on a college in occupied Luhansk, which it claimed killed six students and injured 39. Ukraine's General Staff countered that it was a strike on a centre for Advanced Unmanned Technologies run by Rubikon, Russia's unmanned systems force.Russian Foreign Minister Sergei Lavrov informed his US counterpart, Marco Rubio, that Russia would begin striking "military sites" in Kyiv in retaliation, warning foreign citizens, including diplomats, to leave. Moscow specifically mentioned using its newest Oreshnik intermediate range missile in the attacks, which it has also forward-positioned in Belarus.Future Outlook of the ConflictThe current trajectory suggests that Ukraine's strategy of targeted strikes on Russian logistics and supply lines, combined with enhanced air defense capabilities from international partners, will continue to challenge Russia's military advances. However, Russia's demonstrated willingness to escalate attacks on urban centers and its deployment of advanced weaponry indicate that the conflict may enter a more intense phase.As Russia depletes its financial resources and struggles to replace casualties, its ability to sustain current operations may diminish. Conversely, Ukraine's increasing success in securing international military support and refining its asymmetric tactics could shift the balance further in its favor, though the long-term outcome remains uncertain as both sides adapt their strategies.

On 29 May 2026, Israeli air strikes and a ground push that crossed the Litani River resulted in at least five civilian deaths in southern Lebanon, while Pentagon‑level talks were scheduled to address the rapidly deteriorating security situation. Israeli Ground Advance Across the Litani River Prime Minister Benjamin Netanyahu announced that Israeli forces had moved north of the Litani River, roughly 30 km from the border, marking a significant expansion of the ground offensive. The advance was accompanied by air strikes on towns such as Abbasiyeh and Deir Qanoun al‑Nahr, and evacuation warnings for seven additional southern towns. Casualty Toll and Child Impact Figures Five civilians killed in the latest strikes. Four deaths in Abbasiyeh and one in Deir Qanoun al‑Nahr. UNICEF reported 15 children killed and 62 injured in the past week, averaging 11 child casualties every 24 hours. Lebanese Ministry of Public Health cites 77 children killed or injured in the last seven days. Since March 2, 126 civil‑defence workers have been killed and 310 wounded. Humanitarian Crisis and Regional Stability Risks The intensified bombardment has forced hundreds of thousands of Lebanese to flee their homes, with about 40 hospitals in the south already closed. Aid groups, including Doctors Without Borders, warn they may have to withdraw if security does not improve, compounding the risk of a broader humanitarian catastrophe. Prospects for Pentagon Talks and Conflict Trajectory Lebanese and Israeli delegations are set to meet at the Pentagon, where Lebanon will demand an immediate halt to Israeli attacks. Israeli Brigadier General Amichai Levin and Lebanese officer Georges Rizkallah will represent their sides. The outcome of these talks could influence whether the conflict remains localized or escalates further, especially given U.S. Secretary of State Marco Rubio's expressed support for Lebanon’s sovereignty.

The LeadIga Swiatek has called for the French Open to make changes to the layout of their courts after multiple players were forced to withdraw this week having been injured when tripping over obstacles at the back of the Roland Garros courts. The world number one player expressed concern that the current setup is not safe for competitors.The Court Safety CrisisThe most recent incident occurred on Friday when Turkish player Zeynep Sonmez ran into one of the Lacoste advertising boards placed at the back of the court and fell to the floor. After a medical time out, Sonmez, alongside her partner Tatjana Maria, was forced to retire from her second round doubles match while trailing 2-0.Earlier in the week, Belgian player Alexander Blockx was forced to withdraw after injuring himself on the rain covers at the back of a practice court. In a statement on Instagram, Blockx revealed: "Unfortunately during today's practice I heard a snap in my ankle while I sprained it thanks to the 'really necessary' covers at the back of the court at Roland Garros, which is why I had to withdraw from tomorrow's match."Great Britain's Katie Boulter also had a near miss, saying the boards need to be removed after she tripped on one during her second-round match. "THESE THINGS HAVE TO GO. Got lucky last night but next time I might not be…" she wrote on social media.Historical ContextThis is far from a new issue at Roland Garros, which uses these panels towards the back of the court to advertise their sponsors. In 2017, David Goffin was forced to retire from his third round match due to a similar incident. No other grand slam tournament places their rain covers behind the baseline, making the French Open unique in this aspect.The issue is particularly problematic on clay courts due to the tendency for players to move and defend from deeper positions on the surface. This increases the likelihood of players running into the obstacles at the back of the court during extended rallies.Tournament UniquenessThe French Open is the only big tournament that still uses line judges, with the tournament placing their boards next to lines people in the court. Arthur Ashe Stadium at the US Open is the only other grand slam court with advertising hoardings on the court, but those boards are pressed directly to the back wall, not placed in the playing area.This design choice has been a point of contention for years, with players consistently raising concerns about the safety implications of having obstacles in the playing area. Despite these concerns, the tournament has maintained this setup, citing tradition and sponsorship requirements.Player Reactions"I didn't see the incidents, but I heard about them," said Swiatek. "Obviously if these things happen, there needs to be a reaction, because there are other ways for us to be visible for sure, you know? It's a shame, and it shouldn't – I hope they're going to put them in a different place or just put the advertising in a different way there, because it's not safe for sure."After her straight sets win over Viktorija Golubic, Marta Kostyuk expressed skepticism that the tournament would make changes: "Honestly, I feel like there are some rules that no matter what happens, they just cannot be changed, and no matter how much you speak about it or how much you fight over it, it's just the rules. I don't know."Swiatek's Path ForwardDespite the concerns about court safety, Swiatek continues to build confidence and momentum in her first major tournament alongside her new coach, Francisco Roig. After projected tough opponents like Jelena Ostapenko and Elena Rybakina were eliminated in round two, Swiatek now faces a different challenge in the form of Marta Kostyuk.Kostyuk is on a 15-match winning streak and has not lost on clay this year after winning titles in Rouen and Madrid. "I definitely have a different feeling going into this match, because I feel like last time that I played her in Cincinnati, I lost this match way before it even started, and I don't feel the same this time," said Kostyuk.

The Making of a Coach: Mikel Arteta's Early Years Santi Cazorla recalls watching Mikel Arteta during their time at Arsenal, noting that Arteta would pause and rewind matches to analyze player positions and strategies. This behavior hinted at his future as a coach, and Cazorla joked that Arteta was the worst person to watch a match with because of his constant analysis. Arteta's Formative Experiences Born in Gipuzkoa, Spain, Arteta was known for his intelligence, character, and competitiveness from a young age. His teammates at Antiguoko, a youth club in San Sebastián, described him as 'alive' with a spark in his eyes. Arteta's ability to grasp concepts quickly and his determination to find solutions on the pitch set him apart. The Influence of La Masia At 14, Arteta began training at Athletic Club, where he was coached by José Luis Mendilibar. Mendilibar noted Arteta's exceptional intelligence on the pitch and his ability to explain his vision to others. This experience laid the groundwork for Arteta's future as a coach. Barcelona's La Masia: A Life-Changing Experience Arteta's time at Barcelona's La Masia, alongside future stars like Andrés Iniesta and Carles Puyol, was instrumental in shaping his football philosophy. The traditional Catalan farmhouse provided a unique environment where young players lived and trained together. Arteta's experiences and relationships during this period significantly influenced his approach to the game. Maturity and Adaptability Arteta's teammates and coaches highlight his maturity and adaptability as key factors in his success. Despite being a year younger than his peers, Arteta demonstrated a level of confidence and self-assurance on the pitch that impressed those around him. His ability to demand the ball and dictate play showcased his natural leadership qualities.

The Royal Return to Epsom Downs King Charles and Queen Camilla will attend the 247th running of the Epsom Derby on June 6, reviving a traditional royal engagement that Queen Elizabeth II maintained for most of her 70-year reign. Their presence marks a significant moment for British horse racing, bringing renewed attention and prestige to one of the sport's most prestigious events. A Historic Tradition Revived The late Queen attended nearly every renewal of the Classic at Epsom Downs between 1953 and 2020, missing only two races during that period. Her attendance began just four days after her coronation in 1953, when her colt Aureole finished second in the race. King Charles and Queen Camilla were previously at Epsom in 2024 to watch the Oaks, which is run a day before the Derby, but their attendance for the track's most famous race represents a full return to tradition. Declining Attendance Figures The official attendance for the Derby in 2022 was 37,274, just 770 below the 2019 figure of 38,044, but last year's race pulled in only 22,787 fans. The significant decline in recent years has raised concerns about the future of the historic event. The royal attendance is expected to boost ticket sales and media coverage, potentially reversing this downward trend. Boost for British Horse Racing The king and queen are patrons of the Jockey Club, which owns and operates Epsom. Their attendance is seen as a proud moment for everyone connected with the racecourse, as royal presence has been synonymous with the meeting for generations. While the royal colors will not be involved in either the Derby or the Oaks, their string includes runners that could be entered on the Classic undercard races. Future Outlook for the Derby With the royal couple's attendance, the Epsom Derby is poised to regain its status as a highlight of the British social and sporting calendar. The event organizers hope this will mark the beginning of a sustained revival of interest in the race, potentially leading to increased investment in facilities and greater media coverage. The presence of the monarch may also encourage a new generation to engage with horse racing, ensuring the tradition continues for decades to come.

The Lead: Evaluating Colombia's Peace InitiativePresident Gustavo Petro's "Total Peace" plan, launched with high hopes in 2025, has reached a critical juncture as Colombia continues to grapple with decades-long internal conflicts. The ambitious initiative represents a significant shift from previous security-focused approaches, prioritizing dialogue and negotiation with armed groups to achieve lasting peace.The Political Strategy Behind "Total Peace"Petro's administration conceived "Total Peace" as a comprehensive approach to addressing Colombia's complex armed conflict, which involves multiple guerrilla groups, drug trafficking organizations, and criminal networks. The plan differs from previous government strategies by simultaneously engaging with various armed groups rather than focusing exclusively on the largest guerrilla forces. This multi-pronged approach has both advantages and challenges, as it attempts to address the root causes of conflict while navigating the complex political landscape of Colombia.Progress and Setbacks in ImplementationThe implementation of "Total Peace" has yielded mixed results. While some smaller armed groups have engaged in preliminary talks and certain regions have seen temporary reductions in violence, the program has faced significant obstacles. Key challenges include resistance from hardliners within both the government and armed groups, difficulties in establishing verifiable ceasefires, and the persistent influence of drug trafficking networks that benefit from the status quo.International Reactions and SupportColombia's "Total Peace" initiative has drawn varied responses from the international community. Some nations and organizations have praised the government's commitment to peaceful resolution, offering diplomatic support and conditional aid. Others have expressed skepticism, questioning whether the approach is too lenient on armed groups and concerned about potential human rights implications. The United Nations has maintained a cautious stance, offering technical assistance while emphasizing the need for robust monitoring mechanisms.Political Divisions and Public OpinionThe initiative has deepened political divisions within Colombia. Supporters view "Total Peace" as a necessary alternative to failed military approaches that have cost thousands of lives and yielded limited results. Critics, including opposition politicians and some military leaders, argue that the plan demonstrates weakness and could embolden armed groups. Public opinion remains divided, with polls showing significant regional variations and differing levels of support based on personal experiences with conflict.Economic Implications of the Peace ProcessThe economic dimensions of "Total Peace" are substantial. Successful implementation could unlock significant development opportunities in regions previously affected by conflict, potentially boosting agricultural production, infrastructure development, and tourism. However, the transition period presents economic challenges, including the need for reintegration programs for former combatants and addressing the economic roots of conflict. The government must balance immediate humanitarian needs with long-term economic planning to ensure sustainable peace.Future Prospects and Pathways ForwardAs "Total Peace" enters its second year, several critical questions remain. Can the government maintain political consensus amid growing challenges? Will armed groups demonstrate genuine commitment to peace negotiations? How will the program address the complex intersection of drug trafficking, illegal mining, and armed conflict? The coming months will be crucial in determining whether "Total Peace" will be remembered as a visionary approach to ending Colombia's protracted conflict or as an ambitious but ultimately unfulfilled initiative.

The Lead: Israel's Gaza Expansion Beyond Agreed TermsAfter two years of relentless bombardment and ground invasions, Israel's future in Gaza had appeared to be settled with the signing of United States President Donald Trump's 20-point peace plan on October 9, 2025. Under the terms of that agreement, Israeli forces were meant to withdraw behind what planners called the "Yellow Line", maintaining control of 58 percent of the territory, with their full withdrawal to be set at a date to be determined.The Event Details: Military Expansion and Territorial ChangesThat withdrawal hasn't happened. In fact, in the months since, as well as killing at least 922 people in near-daily strikes on the enclave during the "ceasefire", Israel has expanded its territory by about 11 percent. According to satellite data gathered in March, it has also established at least 32 military outposts, a ground barrier and infrastructure along what was supposed to be a temporary line.The Data Analysis: Humanitarian Crisis and Casualty FiguresSince October last year, numerous humanitarian agencies, including Oxfam, have accused Israel of compounding the humanitarian crisis in Gaza by restricting deliveries of aid and other essential goods. To date, since the onset of its war on Gaza in October 2023, Israeli forces have killed at least 72,819 men, women and children in Gaza, with many thousands more missing and presumed dead under the rubble. By 2025, Israel had caused a confirmed famine in the enclave and has now decimated nearly all infrastructure needed to support life.The Impact Analysis: International Response and Legal Implications"If Israel's ultimate plan is to exercise permanent effective control over the entirety of the Gaza Strip, we are talking about unlawful annexation," Michael Becker, a professor of international human rights law at Trinity College in Dublin, told Al Jazeera. "As the International Court of Justice reaffirmed in a 2024 advisory opinion, annexation constitutes a violation of the bedrock prohibition of the acquisition of territory by force."Hopes that the US might enforce its own conditions on Israel also appear ill-founded. Since announcing a ceasefire in the enclave in October last year, the US has failed to react as Israel has expanded and entrenched its presence in Gaza, choking off access to about two-thirds of the enclave for its inhabitants by April 2026.The Future Outlook: Population Displacement and Regional StabilityIsrael's answer to how Gaza's population can survive in such a reduced territory is what they call "voluntary emigration." "The plan for voluntary emigration from Gaza will also be implemented, all at the proper time and in the proper manner," Defence Minister Israel Katz wrote in a statement. Observers typically acknowledge that this means the ethnic cleansing of the enclave."The idea of permanently removing Palestinians from Gaza smacks of forced displacement and would also violate the fundamental right to self-determination of the Palestinian people," Becker said. However, he noted that the spotlight of international attention has now shifted from the crisis in Gaza to the US and Israel's war on Iran, as well as Israel's actions in Lebanon, where it has occupied large swaths of the south of the country.
