The deployment of reflective mirrors on satellites and the launch of thousands more satellites into low Earth orbit could have significant consequences for human health and ecosystems. Leading sleep and circadian rhythm researchers have raised concerns about the potential disruption to natural night-time light environments.The US Federal Communications Commission (FCC) is considering plans by Reflect Orbital to illuminate parts of the Earth at night using reflective satellites, as well as applications from SpaceX that could dramatically expand satellite numbers in low Earth orbit.2,500 researchers from over 30 countries have expressed concerns that altering the light-dark cycle could disrupt biological clocks that regulate sleep and hormone secretion in humans and animals, migration in nocturnal species, seasonal cycles in plants, and the rhythms of marine phytoplankton.Prof Charalambos Kyriacou, president of the European Biological Rhythms Society (EBRS), emphasized that "plants need the night" and that eliminating it could have global implications for food security.Reflect Orbital aims to use satellites equipped with large reflective mirrors to redirect sunlight onto areas roughly 5km to 6km wide "on demand", with brightness adjustable "from full moon to full noon".Meanwhile, SpaceX has proposed launching up to 1m satellites to create a giant solar-powered computing network in orbit designed to run artificial-intelligence workloads.Ruskin Hartley, chief executive of DarkSky International, noted that scientific studies have already shown that the existing number of satellites in orbit has increased diffuse night sky brightness by roughly 10%.Experts warn that if current trends in satellite launches and debris generation continue, night sky brightness could increase substantially over the coming decade, approaching the threshold astronomers have set for preserving naturally dark skies.

Virgil van Dijk openly criticised Liverpool’s performance after a crushing 4‑0 defeat to Manchester City in the FA Cup quarter‑final, saying the side effectively "gave up" and offering a direct apology to the club’s supporters. The Dutch defender described the loss as the most severe under manager Arne Slot, noting that the timing of the defeat makes it especially hard to rebound for the Champions League first‑leg against Paris Saint‑Germain on Wednesday. Van Dijk pointed out that Liverpool allowed four goals in an 18‑minute spell around the break, a collapse that has contributed to the club’s tally of 15 defeats across all competitions this season (excluding the Community Shield). "It’s on us," he said, expressing remorse for the second‑half display and acknowledging the mental strain of a difficult campaign. He also took personal responsibility for the penalty that gave City the lead, marking his fourth spot‑kick conceded this season after 319 appearances for Liverpool. Regarding the manager, Van Dijk stated, "Slot is responsible as the manager, but we are the ones on the pitch." He added that the team let both the fans and themselves down, especially after the penalty incident. Looking ahead, the captain warned that the upcoming match in Paris will be "very difficult", but stressed that Liverpool must fight in the remaining three games to salvage the season. Van Dijk also reflected on a perceived loss of the "togetherness" that defined his years at the club, attributing it to a major squad overhaul and a transitional period that hampers consistency.

The UK government has announced that it will not pursue a ban on foie gras imports and will not restrict fur imports, citing the need to prioritize trade agreements with the EU. This decision reverses a previous commitment to restrict the import of these products, which are often associated with animal cruelty.The move has been criticized by animal welfare charities, who argue that the UK's high animal welfare standards should not be compromised for the sake of trade agreements. The RSPCA and other organizations have expressed disappointment and concern about the impact on animal welfare.The UK had previously banned fur farming in 2000 and the production of foie gras in 2006, but imports of these products have continued. The EU has made it clear that it will not allow member states to ban each other's products on animal welfare grounds, which has limited the UK's ability to restrict imports.The decision is seen as a significant concession to the EU as the UK seeks to secure a trade deal. The government has stated that it is prioritizing economic growth and has set up a working group to examine the fur industry.Animal welfare charities and some businesses are urging the government to reconsider its decision and maintain its commitment to banning these products. Some restaurants and shops have already removed foie gras from their menus and shelves, citing concerns about animal welfare.

Nasa administrator Jared Isaacman has stated that the possibility of alien life is a crucial factor in planning the agency's space missions. In a recent interview with CNN's Meet the Press, Isaacman emphasized that investigating the existence of alien life 'goes to the heart of many things that we do at Nasa.'Isaacman's comments come as Nasa's Artemis mission to circumnavigate the moon is underway, marking the first lunar mission since 1972. The mission aims to explore the moon's far side and could potentially lay the groundwork for a moon base on the south pole, equipped with telescopes to aid in the search for extraterrestrial life.While acknowledging that he has not encountered any aliens during his own space travels, Isaacman expressed optimism about the likelihood of discovering life elsewhere in the universe. 'With 2 trillion galaxies out there, who knows how many star systems within each of them? I would say the odds that we will find something at some point to suggest that we are not alone are pretty high,' he said.The Artemis mission has also faced challenges, including a malfunctioning $30 million toilet on the Orion spacecraft. However, Isaacman assured that the issue has been addressed, and the crew is prepared for any eventuality.

Several Premier League clubs are struggling to find new shirt sponsors ahead of next season, with nine clubs yet to secure front-of-shirt commercial deals and 12 having not signed contracts. The imminent ban on shirt advertising from gambling companies is having a significant impact on clubs' commercial returns, with the collective loss of income from shirt deals potentially as high as £80m next season.Gambling operators, particularly those serving Asian markets, have been willing to pay more than other companies to sponsor Premier League clubs. However, the removal of gambling firms from the market has led to intense competition among clubs at lower prices. Of the 10 top-flight clubs with gambling sponsors this season, only Bournemouth have announced a replacement, with the club's stadium sponsor Vitality moving on to the shirt in a cut-price deal.Brentford are close to announcing that their existing training kit sponsor, the job search website Indeed, will be on their shirt next season, while Everton and Fulham appear set to buck the trend as they are in advanced negotiations with the foreign exchange trader CMC markets. However, seven clubs with gambling companies' backing remain in the market, including Chelsea and Newcastle, who are still seeking new sponsors.The ban on gambling sponsorships has exacerbated the divide between the big six clubs and the rest of the Premier League in terms of the sponsors they can attract. Arsenal, Liverpool, Manchester City, and Manchester United are locked into long-term deals worth between £50m and £60m a year, while Leeds and Brighton have long-term contracts with Red Bull and American Express respectively.

Major League Soccer (MLS) Commissioner Don Garber has expressed his approval of FIFA's dynamic pricing strategy for the upcoming World Cup, which has significantly raised ticket prices across all games. The tournament is set to take place in the US, Mexico, and Canada this summer. Garber made these comments in Miami, where he attended the inaugural fixture at Inter Miami's Nu Stadium. He suggested that the high prices resulting from FIFA's dynamic pricing model are justified by the event's exclusivity, stating that Americans are accustomed to such pricing for major events. “FIFA has been smart. They have variable ticket pricing and I'm hoping they'll be providing access to anybody that wants to buy a ticket,” Garber said. “It's not really for me to comment on pricing. [MLS] has nothing to do with that, it's FIFA's decision. But I think it's going to be a premier event and premier pricing Americans are used to.” FIFA's dynamic pricing model has been met with criticism, with some labeling it as “price gouging”. US politicians have also weighed in, writing to FIFA President Gianni Infantino. Supporters' groups have expressed outrage over the rising costs. Recently, FIFA raised the top price of a World Cup final ticket to $10,900, up from $8,600 after the finals draw in December. This represents a significant increase from the $1,600 top price for a World Cup final ticket in Qatar four years ago. Despite the controversy, Garber emphasized that MLS is working to capitalize on the tournament to showcase its growth. Many of MLS' top players, including Lionel Messi and Rodrigo de Paul, are expected to represent their nations during the World Cup. “We're going to be present during the games,” Garber added. “We've just finalized the last shoot for major advertising campaigns. It's the first time we've ever produced anything like that. We'll be advertising in the final and semi-finals with some of our biggest stars that we think will resonate around the world.”

Brighton pulled off a major upset in the Women's FA Cup quarterfinals, defeating Arsenal 2-0 at Borehamwood. The win extended Arsenal's wait for their first Women's FA Cup title in over a decade. Fran Kirby, a former Chelsea forward, played a crucial role in the victory, providing two assists.Madison Haley opened the scoring shortly after halftime with a superb finish into the top corner, and Caitlin Hayes sealed the win with a header from a deep Kirby corner. Arsenal, who had recently knocked out Chelsea in the Champions League, looked disjointed and below their best.In another match, Liverpool secured a semifinal spot with a scrappy 115th-minute goal from substitute Zara Shaw against Charlton Athletic. Shaw's goal came after a scramble in the box, marking her return to competitive action after a 12-month knee injury.Liverpool manager Gareth Taylor praised Shaw's determination, saying, 'What a story, Zara Shaw, eh? The way people speak about her at the club, it couldn’t have happened to a better person.'Charlton's head coach, Karen Hills, expressed pride in her team's performance, stating, 'I’m so proud of the group. The way they performed today, they were outstanding.'
