The Lead Scientists are now probing the inner lives of long-extinct dinosaurs like T rex by studying the skulls of birds, their direct descendants. This approach may provide clues about the behavior and cognitive abilities of these prehistoric creatures. Exploring the Connection Between Birds and Dinosaurs T rex is often depicted as more brawn than brains, but researchers are hoping to explore whether there might be telltale hints of advanced capabilities in the skull, opening up the potential to probe the lived experience of dinosaurs like T rex. Prof Steve Brusatte, a palaeontologist at the University of Edinburgh, is working with an international team of researchers to explore such possibilities. The Science Behind the Study “We can’t put T rex through those tests,” said Prof Steve Brusatte. “But if there are some distinctive features of the brain that maybe tell you with 95% confidence that the animal with that kind of brain is capable of that kind of behaviour today, then we can at least make predictions about these fossils.” The Evolutionary Link Birds are direct descendants of theropod dinosaurs and share many characteristics with them. In fact, a six-day-old quail embryo has a pelvis that looks just like the hips of a theropod like T rex. By studying the brains and behavior of birds, scientists can make educated guesses about the cognitive abilities of their dinosaur ancestors. The Future of Dinosaur Research While the approach may be a long shot, it could provide a new window into the lives of long-extinct creatures. As Brusatte notes, “Birds are survivors. They are adaptable, they evolve quickly, they change quickly.” By studying birds and their connection to dinosaurs, researchers can gain a deeper understanding of the evolution of life on Earth.

The Lead: Alcaraz's French Open Dreams Dashed by InjuryReigning two-time French Open champion Carlos Alcaraz has made the difficult decision to withdraw from this year's Roland Garros tournament and the Italian Open due to a persistent wrist injury. The 22-year-old Spanish star, who became the youngest man to complete the career Grand Slam just this January, will now focus on recovery as he aims to protect his long-term career prospects.The Injury Timeline: From Barcelona to WithdrawalAlcaraz sustained the injury during the first round of the Barcelona Open last week, where he managed to defeat Otto Virtanen before subsequently pulling out of the tournament. The situation escalated when he announced his withdrawal from the Madrid Masters on April 17, fueling concerns about his French Open participation.Following medical tests on his right wrist, Alcaraz and his team made the final decision to shut down his clay season completely. "We have decided that the most prudent thing to do is to be cautious and not participate in Rome or Roland Garros," the world number two stated on social media.The Career Impact: A Setback for a Rising ChampionThis represents a significant blow to Alcaraz's remarkable career trajectory. The seven-time Grand Slam winner had been dominating the clay courts, triumphing at Roland Garros in both 2024 and 2025. Last year's final against Jannik Sinner was particularly memorable, as Alcaraz saved three championship points in what became the longest French Open final in history.Despite his young age, Alcaraz has demonstrated remarkable wisdom regarding his career longevity. "I'd rather come back maybe a bit later, but in great shape, than come back quickly and risk making this injury worse," he explained earlier this week. "I have a long career ahead of me, so I'm not afraid to miss what I have to miss in order to recover as well as possible."The Tournament Landscape: Opening the Door for CompetitorsAlcaraz's absence creates an unexpected opening at this year's French Open, which runs from May 24 to June 7. The Italian Jannik Sinner, who defeated Alcaraz in the Monte Carlo Masters final on April 12, may now be considered the favorite to claim his first Grand Slam title on clay."It's sad news for all of us, me being a competitor you want to play against the best players in the world, and he's definitely the best player on this surface," Sinner commented after his victory at the Madrid Open. "Being that young like he is and like I am, we need to look at our bodies first before worse things [happen]."The Road to Recovery: Wimbledon as the Next TargetWhile the immediate future on clay courts is now on hold, Alcaraz and his team are already looking ahead to the year's third Grand Slam at Wimbledon. Sinner expressed hope that his rival would be back in action by then: "Hopefully, he can be back for Wimbledon, and we all hope for great battles in the future."For Alcaraz, this will be just the second Grand Slam he has missed since making his main draw debut at the 2021 Australian Open. His previous withdrawal came at the 2023 edition in Melbourne due to a hamstring injury. As he navigates this latest challenge, the tennis world will be watching closely to see how the young champion rebounds from this setback.

The Strategic Pivot: Prioritizing Hubs Over RoutesGerman aviation giant Lufthansa Group is implementing drastic operational changes to navigate a supply crisis triggered by geopolitical tensions in the Middle East. The airline has announced the cancellation of 20,000 short-haul flights scheduled until October. This move represents a significant shift in strategy, moving away from less profitable routes to focus exclusively on flights to and from its core hubs in Frankfurt and Munich.Subsidiary Grounding: The airline will ground 27 planes in its short-haul CityLine subsidiary earlier than originally planned.Conservation Goals: By streamlining operations, Lufthansa aims to conserve approximately 40,000 tonnes of jet fuel.Supply Assurance: The company claims to have secured enough fuel for the coming weeks and is pursuing physical procurement measures to stabilize supply for the summer season.The Economics of the Fuel CrisisThe root cause of this operational overhaul is a dramatic spike in oil prices, which has directly translated into a jet fuel shortage. The price of jet fuel has more than doubled in certain markets since the conflict escalated in late February.According to the Associated Press, the global price of jet fuel has surged from about $99 per barrel at the end of February to as high as $209 a barrel at the beginning of April. This volatility is forcing airlines to make difficult financial decisions, as fuel is their most significant operational expense.Europe's Aviation VulnerabilityThe crisis highlights a critical structural weakness in the European aviation sector. European airlines are heavily reliant on imports from the Middle East, with around 75 per cent of the region's jet fuel imports originating from the area.The economic toll is mounting rapidly. EU Energy Commissioner Dan Jørgensen reported that the war is costing Europe approximately 500 million euros ($600m) each day. The European Union is currently warning that the energy crisis could impact prices for months, or even years, to come.A Summer of UncertaintyTravelers are bracing for a turbulent peak season. The combination of fewer flight options and soaring operational costs has already led to higher fees, including increased checked bag charges and fuel surcharges.The International Energy Agency (IEA) has issued a stark warning, stating that Europe has “maybe six weeks or so” of jet fuel remaining. Despite temporary ceasefires, the IEA has warned that flight cancellations could become a reality “soon” if oil supplies remain disrupted, signaling a challenging outlook for the summer travel season.

The European Union is actively preparing contingency measures to address potential jet fuel shortages stemming from the ongoing Iran conflict, which has disrupted global oil supply chains through the critical Strait of Hormuz. Despite assurances that no actual shortages exist yet, the bloc is exploring multiple options including increased imports from the United States and implementing new minimum reserve requirements to ensure energy security for the upcoming summer travel season. Key Developments The EU is considering jet fuel imports from the United States as an alternative supply source New minimum reserve quotas are being evaluated to strengthen the EU's fuel security A "fuel observatory" will be established to monitor jet fuel supplies The European Commission is preparing a broad package of energy and transport measures Airlines have been provided with guidance on passenger rights and public service obligations in case of shortages Data & Market Impact The EU's vulnerability is significant, as the bloc imports 30 to 40 percent of its jet fuel needs, with approximately half of those imports coming from the Middle East. The Strait of Hormuz blockade, which normally handles one-fifth of the world's oil and liquefied natural gas supplies, has created substantial uncertainty in global energy markets. While International Energy Agency head Fatih Birol warned that Europe might have "maybe six weeks or so [of] jet fuel left," EU officials maintain that current market pressures are being managed effectively, with no evidence of actual shortages or widespread bottlenecks. Why This Matters The potential jet fuel shortage carries significant implications for multiple stakeholders across Europe and beyond. For travelers, the situation could lead to increased fuel surcharges, flight cancellations, and higher ticket prices during the crucial summer travel season. Airlines face mounting pressure as fuel costs rise, potentially affecting profitability and route planning. The broader economy could experience disruptions in tourism, business travel, and cargo transportation, with ripple effects across multiple industries. Regionally, countries with heavy reliance on Middle Eastern fuel imports may face more acute challenges, potentially exacerbating existing economic disparities within the EU. The situation also highlights the critical importance of energy diversification and strategic reserves in an increasingly volatile global security environment. Expert Insight The EU's measured response reflects a calculated balancing act between addressing legitimate concerns and preventing market panic. Transport Commissioner Apostolos Tzitzikostas' emphasis on market management suggests confidence in the bloc's ability to navigate this challenge through coordinated action rather than emergency measures. The consideration of minimum stock obligations represents a significant policy shift toward greater self-sufficiency in energy security, potentially reshaping long-term energy procurement strategies. The focus on establishing a fuel observatory indicates a recognition that real-time monitoring and data-driven decision-making will be crucial in managing future supply disruptions. This situation may accelerate the EU's transition toward alternative aviation fuels and more diversified supply chains, potentially accelerating the aviation industry's decarbonization efforts. What Happens Next The European Commission's upcoming energy and transport package will likely include concrete measures to strengthen the EU's fuel security posture. We can expect increased diplomatic efforts to secure alternative supply routes and potentially negotiate new import agreements with non-Middle Eastern suppliers. The aviation industry may implement more sophisticated fuel management strategies, including route optimization and increased fuel efficiency measures. The consideration of minimum reserve obligations could lead to new regulatory requirements for member states, potentially reshaping Europe's energy storage infrastructure. Longer term, this crisis may accelerate investment in sustainable aviation fuels and technologies that reduce dependency on conventional jet fuel. The situation will also likely intensify discussions about energy security within the EU, potentially leading to more coordinated approaches to emergency preparedness and response mechanisms.

The Lead: OpenAI's Strategic Moves OpenAI has been making headlines with recent acquisitions of personal finance startup Hiro and media company TBPN, prompting analysts to question whether these moves represent strategic attempts to address the company's existential challenges in a competitive AI landscape. The Acquisition Strategy: Beyond Talent Acquisition On TechCrunch's Equity podcast, analysts debated whether these acquisitions were simply acqui-hires or attempts to solve deeper strategic problems. The Hiro acquisition, a personal finance startup founded just two years ago, appears to be primarily a talent acquisition. Meanwhile, TBPN, a business talk show, will allegedly retain editorial independence but now operates under OpenAI's public policy and communications structure. These acquisitions, while small compared to OpenAI's scale, suggest a continued experimental approach to finding new directions beyond their core ChatGPT product. The Financial Analysis: Seeking Sustainable Business Models OpenAI faces significant questions about whether ChatGPT can generate sufficient revenue to create a sustainable business without relying on massive private funding. The acquisition of Hiro represents a bet on developing new products with "more hooks than just a chatbot, and maybe something worth paying more for," according to podcast analyst Sean O'Kane. The enterprise market, where companies like Anthropic are finding success with Claude Code, represents the most promising path to sustainability for AI companies. This explains OpenAI's reported obsession with Anthropic's rising influence in the enterprise space. The Industry Impact: Competition and Market Evolution These strategic moves reflect the evolving competitive landscape in AI, where OpenAI and Anthropic are increasingly seen as direct competitors. While both companies could potentially succeed in a growing market, Anthropic's success with enterprise solutions has clearly rattled OpenAI. The acquisitions also highlight the broader challenge AI companies face in monetizing their technology while maintaining public trust. OpenAI's public image has suffered recently, making the TBPN acquisition a strategic attempt to shape its narrative in the public eye. The Future Outlook: Navigating AI's Competitive Landscape Looking ahead, OpenAI will need to balance its focus on improving ChatGPT and GPT models for enterprise competition with exploring new product categories that could provide additional revenue streams. The company's ability to develop sustainable business models beyond its flagship product will be crucial in the coming years. Meanwhile, the competition with Anthropic is likely to intensify, particularly in the enterprise and coding tools market where both companies see the most significant growth potential. The success of these strategic acquisitions may determine whether OpenAI can maintain its position as a leader in the rapidly evolving AI industry.

Manchester City manager Pep Guardiola has described Sunday's Premier League clash with leaders Arsenal as a 'final,' emphasizing that a defeat would significantly hinder his team's title aspirations. City currently trails Arsenal by six points but has a game in hand, which could cut the gap and intensify the pressure as the season enters its critical phase.Guardiola acknowledged the high stakes, stating, 'If we lose, it is over.' He expressed confidence in his team, highlighting the importance of belief at this stage of the season. 'If you could buy confidence in a supermarket, we would buy it immediately,' he said, adding that City's confidence is 'good' and they are 'ready' for the match.The Spaniard also mentioned that Nico O'Reilly is fit after recovering from a hamstring injury. Guardiola stressed that City must elevate their performance to sustain a title push, saying, 'We need to get even better.' He dismissed the label of underdogs, asserting, 'Maybe we're not' and that his team aims to challenge Arsenal.Guardiola expressed pride in his team's continued challenge on multiple fronts, stating, 'We are still here. I am proud to be there, still challenging them.' The outcome of Sunday's match could prove decisive in the Premier League title race.

Dan Skelton is already set to be crowned the United Kingdom’s champion trainer over jumps for the first time this season, yet he still has several objectives left as the campaign reaches its climax.Earlier this month Skelton made history by becoming the first trainer to surpass £4 million in prize money during a British jumps season. With a 320‑mile journey to Ayr scheduled for Saturday, he will field five runners and hopes to chip away at the £200,000 needed to break the £5 million barrier.His yard has already recorded victories at 39 of Britain’s 41 jumping tracks this season. The only venues still without a win are Perth and Plumpton, where Skelton entered twenty runners – including several favourites – but fell short. Two of his horses will contest Plumpton’s Sussex Stayers’ Handicap Hurdle on Sunday.“It’s never been done before, so we’re going to give it our best shot,” Skelton said on Friday. “We just can’t quite seem to get over the line at Plumpton, but maybe Sunday will be the day that we do.”The Scottish Grand National has become a pivotal fixture in the trainers’ championship over the past two years. With Willie Mullins already out of contention for the title, his stable will field only one runner at Ayr as he attempts a third consecutive Grand National double – winning at Aintree and then at Ayr.Patrick Mullins, who rode unshipped from Grangeclare West at Aintree last weekend, will take the reins on Road To Home. The horse was narrowly beaten in the Fulke Walwyn/Kim Muir at Cheltenham last month and will carry six pounds more on Saturday.Among the local contenders, King Of Answers (currently 3.35 odds) trained by Lucinda Russell and Michael Scudamore appears a strong bet at about 7‑1. The horse was a runner‑up in the National Hunt Chase at Cheltenham and will be only three pounds heavier for the four‑mile test at Ayr.Other notable entries include Traprain Law for Patrick Wadge, who previously won the course‑and‑distance race, and Diamond Dealer, whose front‑running style could prove decisive if the horse settles into its usual rhythm.In the broader betting market, Gibbs Island (2.20) and Twistthenightaway (2.55) are also highlighted as potential performers, while Pride Of Arras (2.35) aims to repeat its Dante success.Overall, Skelton’s pursuit of the £5 million season total adds extra intrigue to an already high‑stakes Scottish Grand National, promising a decisive showdown for the jumps championship.

Andoni Iraola has formally notified AFC Bournemouth that he will step down when his contract runs out at the close of the 2025‑26 campaign. The 43‑year‑old manager is expected to explore other Premier League opportunities over the summer.While a move back to his boyhood club Athletic Bilbao remains a possibility, the club’s preferred candidate to replace Ernesto Valverde appears to be former Borussia Dortmund boss Edin Terzic.At Bournemouth, the race to replace Iraola is already heating up. Marco Rose, who succeeded Terzic at Dortmund and most recently managed RB Leipzig, is widely tipped as the leading candidate. Kieran McKenna of Ipswich Town, despite being under contract until 2028, is also generating interest.Players were informed of Iraola’s impending exit after a Tuesday training session, ending months of speculation that kept his staff in the dark. The manager maintained regular contact with director of football Tiago Pinto and technical director Simon Francis throughout the 15‑month negotiation period.In a club‑issued statement, Iraola said, "I feel this is the right moment for me to step away, but I will always carry fantastic memories of this club." Bill Foley, Bournemouth’s owner and chair, praised Iraola’s impact, noting he brought “intensity, innovation, and a clear philosophy that elevated AFC Bournemouth both on and off the pitch.”Despite a recent victory over Arsenal and a push for the club’s best Premier League finish, Bournemouth accepted that retaining Iraola was unlikely. The board is now accelerating the search for a successor, with a new appointment expected within the next fortnight.Iraola’s tenure has been marked by historic achievements: last season he guided Bournemouth to a record points total, matching the ninth‑place finish recorded by Eddie Howe in 2016‑17. He also oversaw the sale of key players – Dean Huijsen, Illia Zabarnyi, Milos Kerkez, Dango Ouattara, and Antoine Semenyo – for a combined fee exceeding £250 million, demonstrating his ability to balance on‑field success with financial prudence.A former Athletic Bilbao full‑back with 510 appearances, Iraola has long expressed affection for the Basque side, though he has hinted he would prefer to preserve his legacy after a 12‑year playing career there.Crystal Palace publicly lauded Iraola after confirming manager Oliver Glasner’s departure, but most analysts agree the former will attract interest from larger clubs.Earlier this season, Iraola hinted to the Guardian that the campaign could be his last at Bournemouth, saying, "Sometimes there is a moment after some seasons where you feel maybe the message does not go the same way to the players."Bournemouth’s next fixture is against Newcastle United at St James’ Park, where manager Eddie Howe has yet to defeat his former club.

Rory McIlroy is looking to regain his form and mindset in the final round of the Masters, following a challenging third round that saw him lose his six-stroke lead. McIlroy, the defending champion, carded a one-over par 73, which allowed Cameron Young to close the gap and tie for the lead heading into the final round.McIlroy believes that a 'free' state of mind will be crucial in the final round. He reflected on his 2025 Masters victory at the same venue, hoping to draw confidence from that experience. 'I'd like to think that I'll play a little bit freer and I'll play, like I've already got a Green Jacket, which I do,' McIlroy said. 'Sometimes I maybe just have to remind myself of that.'McIlroy plans to work on his swing at Augusta National's driving range to iron out kinks that affected his game during the third round. He knows he needs to improve significantly to retain his chances of winning. 'There's a long way to go,' McIlroy added. 'This golf course has a way of, when you're not quite feeling it, you struggle.'Cameron Young, who shot an impressive 65 in the third round, is also in contention. Young is seeking to emulate McIlroy's achievement of winning the Players Championship and Masters within a short period. However, he downplayed the significance of this potential historical parallel, emphasizing that his past results do not guarantee future success.The final round pairing will feature McIlroy and Young, which McIlroy described as a 'comfortable group' for both of them. McIlroy concluded, 'I'm still tied for the best score going into tomorrow, so I can't forget that, but I do know I'm going to have to be better if I want to have a chance to win.'
