The Pothole Puzzle Britain's pothole problem is a complex issue that requires a long-term solution. According to Phill Wheat, a professor of transport econometrics at the University of Leeds, the "spiral" of pothole formation can be avoided if funding for road maintenance is increased. The Cost of Inaction Once holes and cracks start appearing in a road, they grow and proliferate quickly. Vehicle wheels act like jackhammers around every bump and dip. Once the surface starts breaking up and water loosens the lower layers of the road structure, the opportunity to dress or replace the surface soon passes, and rebuilding at much greater expense becomes unavoidable. A Strategy for Success Highway authorities need to prioritise and schedule all roads for resurfacing or rebuilding. That will significantly increase the funding requirement in coming years, but once the programme is well advanced, reactive repair costs will decline sharply. Highway authorities need to model cost projections to show central government that more funding now will save money in the longer term. Funding and Implementation At least some of the extra funding could be raised by local traffic authorities from levies on road users, utilities that dig up roads, and employers that provide staff parking. Taxes rarely win votes, but if they guaranteed better roads and pavements, and lower insurance premiums, people might grudgingly accept them. A Call to Action There must be no cutting corners when rebuilding roads: if they continue to deform under the weight of ever-heavier vehicles, we'll end up in a spiral again. A flexible maintenance strategy and interagency working are crucial to keeping up with repairs to our roads.

The Failed Dealmaker: Trump's Iran Dilemma For weeks, Donald Trump has tried to find a way to end the war he started with Iran – a deal that would allow him to declare victory and move past the conflict before it causes severe damage to the global economy and sinks Republican chances in the US midterm elections. But the self-proclaimed master dealmaker can't seem to stop sabotaging his own negotiations or to acknowledge that Iran is now in a better position to demand concessions than it was before the war. Strategic Missteps: From Military Action to Negotiation Deadlock Over the Memorial Day holiday, Trump skipped his eldest son's wedding in the Bahamas and canceled plans to spend the weekend at his New Jersey golf club. The last-minute changes heightened speculation that Trump was ready to unveil a deal to end the war. Trump then announced that he would hold a cabinet meeting at Camp David, the presidential compound in Maryland that has been the site of historic diplomatic summits. But that meeting was moved back to the White House, as it became clear that Trump had not been able to close a deal he could announce with great fanfare. The Art of the Deal: Trump's Negotiation Paradox Why has an agreement eluded the business titan who wrote the bestselling 1987 book The Art of the Deal? Trump admires strongman leaders and is loth to project any sign of weakness – and he's afraid of reaching a deal with Iran that makes him look weak. The president is also sensitive to criticism that any agreement he negotiates will be worse for the US than the 2015 nuclear deal between Iran and six world powers, which was brokered by Barack Obama's administration. Leverage Reversed: How Iran Gained the Upper Hand Trump's main problem is that Iran has more leverage than he does – and Iranian leaders are well aware of that advantage. On 28 February, Trump launched a joint US-Israeli war against Iran, killing the supreme leader, Ayatollah Ali Khamenei, and other top military and political officials. But Iran retaliated with missile and drone strikes against US military bases across the Middle East, and it targeted the energy infrastructure of its Gulf neighbors. Iran also deployed its most effective economic weapon: it closed the strait of Hormuz, through which more than a fifth of the world's oil supply passed each day. Economic Fallout: Global Disruption and Rising Oil Prices The closure of the Strait of Hormuz – along with Iranian attacks on pipelines and gas fields in Kuwait, Saudi Arabia, Qatar and the United Arab Emirates – disrupted the global economy and increased oil prices. In the US, average gas prices have jumped by 50%, up to nearly $4.50 per gallon, since Trump launched the war. Trump and his ally, the Israeli prime minister, Benjamin Netanyahu, could not topple the Islamic regime that rose to power after Iran's 1979 revolution. Instead, they ended up strengthening it – by allowing Tehran to deploy its geographic control of the strait of Hormuz into a weapon that could instigate a global energy crisis and a worldwide recession. The Emerging Deal: Limited Concessions and Unresolved Issues The emerging deal is focused on solving a problem that didn't exist before Trump started this war: fully reopening the strait of Hormuz to commercial shipping so that oil prices can stabilize. Under a draft agreement being circulated to US allies, Washington would also lift its blockade of Iranian ports and allow Tehran to access about $12bn in frozen assets. Once again, Trump seems to be aiming for a limited deal with Iran that defers the most difficult questions to future talks, which could drag out for months or even years. Iran's Resilience: Military Strength Preserved In some ways, Iran has emerged stronger after a war intended to decimate its military capabilities. A CIA report sent to Trump earlier this month found that Tehran had managed to retain a significant part of its missile capabilities. The analysis said Iran preserved about 70% of its prewar stockpile of missiles and about 75% of its mobile launchers. The report also concluded that Iran was more resilient than US officials had claimed, and it could survive a naval blockade for months. Political Calculations: Midterm Elections and Trump's Dilemma At his cabinet meeting, Trump said he didn't care about the midterm elections and wasn't in a rush to reach a deal. "It's got to be perfect," Trump told reporters, adding: "I didn't do this to get a crummy agreement." Despite his weak position, Trump insists that he will strike a better deal with Iran than the one negotiated by the Obama administration in 2015. That agreement provided Tehran with relief from international sanctions in exchange for limits on its nuclear enrichment. The Unintended Consequences: Strengthening the Adversary Trump could have avoided starting a regime-change war that failed, leaving the world to deal with its consequences. Instead, the master negotiator handed Iran a new economic weapon – and more leverage to extract a favorable deal. The worst thing you can possibly do in a deal is seem desperate to make it. That makes the other guy smell blood, and then you're dead. Trump wrote in his famous book. The best thing you can do is deal from strength, and leverage is the biggest strength you can have.

Iran is grappling with a deepening economic crisis as the costs of a prolonged conflict strain public finances and push the regime toward greater authoritarian measures. Ordinary Iranians are bearing the brunt of soaring prices, a collapsing currency and shrinking job prospects. The Economic Collapse Following the Conflict The war has drained state coffers, forcing the government to divert resources from social programs to military spending. This reallocation has reduced subsidies on essential goods, intensified shortages and heightened public discontent. Quantifying the Crisis: Inflation, Unemployment, and Currency Devaluation Inflation has accelerated sharply, with reports indicating double‑digit growth in consumer prices over the past year. Unemployment, especially among youth, has risen as private sector activity stalls under heavy sanctions and reduced investment. The national currency continues to lose value against major foreign currencies, eroding savings and import purchasing power. Regional and Global Implications of Iran’s Struggling Economy The economic turmoil is reshaping Iran’s regional posture. A financially strained regime may pursue more aggressive foreign policies to rally nationalist support, while neighboring markets feel pressure from disrupted trade flows and refugee movements. Outlook: Prospects for Reform or Further Decline Analysts warn that without substantial fiscal relief or a de‑escalation of hostilities, Iran’s economy could enter a prolonged downturn. Potential pathways include limited market reforms, renewed diplomatic engagement to ease sanctions, or continued reliance on state control, each carrying distinct risks for the population and the regime’s stability.

The Soho Society's New Licensing Mandate A society of residents funded by the council could “destroy Soho’s reputation on the international stage” as London’s entertainment district by ferociously objecting to all new bar and restaurant licences, operators in the area have said. The Soho Society, a group of residents established in 1972 aimed at “preserving the character of Soho”, voted in its AGM on Thursday for a new licensing mandate, meaning it will challenge all new applications for bars and restaurants in the area, including renewals of existing licences. The Impact on Businesses and Jobs The society claims the area in central London has seen an intensification of nightlife and unacceptable noise, as well as crime and litter caused by a proliferation of late-night revellers. However, business owners argue that this could strangle small businesses and limit job opportunities for young people. Rupert Power, the owner of Sophie’s, a steak restaurant, and the underground jazz bar Jack Solomons, both on Great Windmill Street, chairs the Soho business alliance, which is made up of 150 small companies. The Data Analysis The Soho Society is estimated to represent about 10% of the district’s residents. A report by the former cabinet minister Alan Milburn said a lack of hospitality jobs was contributing to high youth unemployment in Britain. The UK has the third-highest rate of 16- to 24-year-olds who are not earning or learning among rich European countries. The Impact Analysis The new mandate means it will be very difficult for businesses to open or expand in the area. Philip Kolvin KC, a planning lawyer, said the mandate would cover “pretty much the whole gamut of licence applications, so that rather than promoting innovation and diversity, it stymies it”. This could lead to delayed licensing applications, spiralling legal costs, and development contracts facing expiry. The Prediction Business owners and experts warn that the Soho Society's actions could have a negative impact on Soho's reputation and the local economy. Power added: “It is strangling small businesses, meaning there are less hours and jobs for young people to work. I really worry for young people. To have a minority be in a position of stifling growth that is funded by the council is not ideal.”

The Revolutionary GeneticistCraig Venter, the pioneering geneticist who revolutionized genome sequencing and challenged traditional scientific approaches, has died at age 79. His announcement at the 2001 BioVision conference that humans possess only about 30,000 genes—far fewer than the previously estimated 100,000—shattered scientific assumptions about genetic determinism. "We simply do not have enough genes for this idea of biological determinism to be right," Venter declared, emphasizing that human diversity is shaped primarily by environmental influences rather than hard-wired genetic code.The Breakthrough in Genome SequencingVenter's most significant contribution was developing the revolutionary whole genome shotgun sequencing technique, which allowed for faster, more efficient genome mapping. In 1995, his team achieved the remarkable feat of sequencing the first genome of a living organism, the bacterium Haemophilus influenzae. This breakthrough led to the founding of Celera Genomics in 1998, which aimed to sequence the entire human genome using Venter's innovative methods.The competition between Venter's privately funded Celera and the publicly funded Human Genome Project, spearheaded by the US government and UK's Wellcome Trust, created what scientists described as "testosterone-driven" rivalry. Despite tensions, this competition dramatically accelerated progress in genomics research, culminating in the announcement of the first draft human genome sequence at a White House ceremony in June 2000.The Scientific MaverickVenter was as famous for his bold personality as for his scientific achievements. A brilliant entrepreneur and unapologetic self-promoter, he enjoyed showcasing his success, private plane, yacht, and luxury watches. This flamboyant approach made him both admired and controversial. James Watson, co-discoverer of DNA's double-helix structure, compared Venter to Hitler for attempting to patent human genes, while others nicknamed him "Darth" Venter after the Star Wars villain.His tendency to break scientific protocols became evident when he revealed that much of the DNA used in Celera's human genome sequencing came from his own cells—a decision that annoyed scientists who felt he had subverted standard processes. "I've been accused of that so many times, I've got over it," Venter responded, noting that the analysis revealed he had an abnormal fat metabolism and elevated risk of Alzheimer's disease.A Life Shaped by Science and WarBorn in Salt Lake City, Utah, Venter had an unconventional path to scientific greatness. Growing up in California, he had a poor academic record and initially pursued "pursuits that involved drink, girls and bodysurfing" rather than education. His life took a dramatic turn during the Vietnam War, where he served as a senior corpsman in a naval hospital's intensive care unit in Da Nang."I witnessed several hundred soldiers die, more often than not while I was massaging their hearts – at times with my bare hand – or attempting to breathe life into them," Venter recalled. "Vietnam would teach me more than I ever wanted to know about the fragility of life." This experience sparked his interest in life sciences, leading him to study at the University of California, San Diego, where he earned a PhD in physiology and pharmacology in 1975.The Legacy of a Scientific PioneerAfter being dismissed as head of Celera in 2002, Venter used his substantial payoff to endow the J. Craig Venter Institute with $100 million. There, he pursued ambitious projects including designing energy-producing microbes and synthesizing bacterial genomes. He later founded Human Longevity and Diploid Genomics, companies that aim to combine artificial intelligence with advances in aging research and gene sequencing to extend human lifespans and improve disease diagnosis.While some of Venter's claims about the primacy of environmental influences over genetics have been questioned, his impact on genomics research remains undeniable. His revolutionary sequencing techniques transformed the field, and his competitive approach accelerated what would have otherwise been a much slower process of mapping the human genome. As the scientific community remembers Craig Venter, it acknowledges a complex figure who was simultaneously a brilliant innovator, a controversial competitor, and a transformative force in our understanding of life's fundamental building blocks.

The British Solving Championship: An Opportunity for Chess Enthusiasts This week’s puzzle is a chance to enter an annual national competition in which Guardian readers ­traditionally perform well and in ­considerable numbers. White in the diagram, ­playing as usual up the board, is to play and checkmate in two moves, against any black defence. The Event Details The puzzle is the first stage of the annual Winton British Solving Championship, organised by the British Chess Problem Society and sponsored by the investment ­managers ­Winton. This competition is only open to ­British ­residents and entry is free. To take part, simply send White’s first move by post to Nigel Dennis, Boundary House, 230 Greys Road, Henley-on-Thames, Oxon RG9 1QY, or by email to [email protected]. Entry Requirements and Deadline All entries must be postmarked or emailed no later than 31 July 2026. Entrants must provide their name and home address. Juniors under 18 on 31 August 2025 must also give their date of birth. The Competition Structure The best 15-20 players from the postal round, plus the best juniors, will be invited to the final at Harrow school on Saturday 13 February 2027, where the prize money is expected to be at least £1,600. The winner of the final will have the right to represent Great Britain at the 2027 world ­solving championships, an event where GB are often medal contenders. A Note on Chess and Professionals Back in the 1950s most top English players were amateurs, often civil servants or teachers, who competed in tournaments during their vacations. After the 1970s Fischer boom and English successes brought an influx of sponsors, chess professionals could earn a decent living, but the tide turned again during the 1990s. The breakup of the Soviet Union brought harder international competition, while Nigel Short’s world title defeat and the move to screen rather than print marketing drove sponsors away. A New Grandmaster: Harry Grieve Harry Grieve became England’s latest grandmaster on Tuesday when the 25-year-old, who was British champion in 2022 and helped CSC/Kingston finish second in this season’s UK 4NCL League, won first prize in Budapest with a 7/9 total.

The Lead: PSG's Title Defense MotivationParis Saint-Germain coach Luis Enrique has asserted that his team's motivation to retain their Champions League title surpasses Arsenal's desire to win their first European trophy. PSG, who defeated Inter Milan 5-0 in last year's final, are strong favorites for Saturday's showdown against Arsenal, who are appearing in their first final since 2006.The Event Details: Champions League Final ShowdownThe Champions League final between PSG and Arsenal marks a clash of contrasting narratives. PSG, the defending champions, are seeking to become only the second team in the Champions League era to retain their title, following Real Madrid's achievement. Meanwhile, Arsenal, under Mikel Arteta who boldly declared "We will be European champions on Saturday," are pursuing their first continental trophy.PSG has welcomed back key players Ousmane Dembélé and Achraf Hakimi from injury, with Luis Enrique expected to select 10 of the 11 players who started in last year's final victory. Dembélé, who had been doubtful due to a calf injury, expressed confidence in his participation and emphasized the team's ambition not to "sit on their laurels."The Data Analysis: Luis Enrique's Final RecordLuis Enrique brings an impressive track record to the final, having won 11 of the 12 finals he has contested as a manager. This success rate provides PSG with significant psychological advantage as they prepare for the match. The Spanish coach's experience in high-pressure finals contrasts with Arteta's relative inexperience at this stage of European competition.The Impact Analysis: European Football's Changing LandscapeThis final represents a significant moment in European football's competitive balance. PSG's potential back-to-back victory would solidify their position among Europe's elite clubs and demonstrate the effectiveness of their financial investment. For Arsenal, a victory would mark a return to the pinnacle of European football after a two-decade absence and validate their project under Arteta.The matchup also highlights the evolving dynamics of European football, with PSG's star-studded squad facing Arsenal's more team-oriented approach. The contrast in playing styles and club philosophies adds an intriguing subplot to what promises to be a compelling final.The Prediction: PSG's Historical OpportunityWith the opportunity to make history by becoming only the ninth club to win back-to-back European Cups and the second in the Champions League era, PSG enters the final as overwhelming favorites. Luis Enrique's assertion that "trying to win the second one in a row is" more powerful than Arsenal's first-time quest reflects the confidence within the PSG camp.However, Arsenal's underdog status and Arteta's bold declaration could provide them with the motivation to defy expectations. The final will ultimately come down to which team can execute their game plan more effectively under the pressure of the occasion, with PSG's experience potentially proving decisive in their quest for consecutive titles.

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 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.
