The UK government is set to trial social media curbs for teenagers in a major study aimed at understanding the impact of reduced social media use on young people's lives. Hundreds of UK teenagers will participate in the six-week pilot, which will test different restrictions on social media use, including bans, digital curfews, and time limits on popular apps like Instagram, TikTok, and Snapchat.The trial, led by the UK government, will involve 300 teens across all four nations of the UK, with some participants having their social apps disabled, while others will have access blocked overnight or capped to one hour's use. The goal is to gather evidence on how different restrictions affect young people's day-to-day lives.Technology Secretary Liz Kendall emphasized the importance of testing different options in the real world, stating that the pilots will provide the evidence needed to take the next steps, informed by the experiences of families themselves.The pilot is part of a broader effort to address concerns about the mental health risks associated with unfettered internet access. Nearly 30,000 parents and children have responded to the government's digital wellbeing consultation, which closes on May 26. An independent study, funded by the Wellcome Trust, will also examine the impact of reducing social media use among adolescents.The study, involving about 4,000 students between the ages of 12 and 15 from 10 Bradford secondary schools, will investigate changes in anxiety and sleep quality, time spent with friends and family, wellbeing, body image, social comparison, school absences, and bullying.The UK government faces pressure to follow Australia's move to ban access to social media sites for under-16s, with France, Spain, and Indonesia also considering similar bans. The European parliament has passed a resolution on age restrictions, although it is not legally binding.Critics argue that the pilot is a half-measure that puts pressure on parents rather than holding big tech accountable for the harm caused by social media. Bereaved parents have written to parliamentarians, urging them to support a ban and expressing concern about the consultation process.

Australian swimmer Cameron McEvoy has achieved a lifelong dream by breaking the 50m freestyle world record with a time of 20.88 seconds at the China Open. The Queenslander shattered the longstanding record by three hundredths of a second, a mark set during the era of now-banned super-suits.The 31-year-old athlete expressed his surprise and delight at achieving this milestone ahead of schedule. "That was more of a target for the end of this season, so to have hit it at the moment in March is really special," McEvoy stated upon returning to Brisbane.McEvoy's journey to swimming's pinnacle has been unconventional. Having made his Olympic debut in London as a teenager in 2012, he won bronze medals in relays in Rio and Tokyo before securing his first individual Olympic gold in Paris in 2024 at age 30—well past the typical peak age for elite sprinters.His remarkable rise to dominance stems from a radical rethinking of his training methodology. McEvoy abandoned traditional long pool sessions in favor of strength training and short, explosive sets that mimic the specific requirements of the 50m event. This year, he took an even more extreme approach."I had an off-season which was mainly strength development, and I've barely done much swimming since the [August] World Champs last year, up until this comp," McEvoy explained. "And then this comp was meant to be the transition door into going into more of a sprint-focused regime, but because I got the world record and I've made steps, the idea is just to double down on this and not change it, see how far this can actually take me."The previous world record-holder, César Cielo, congratulated the Australian on his "incredible" swim, sharing a profound insight: "You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete."McEvoy's innovative approach has resonated beyond his own achievements. He receives weekly messages from both elite athletes and former swimmers who have returned to the sport inspired by his methods. "The amount of them that are saying that they're doing lifetime best times and they're deep into their 40s, compared to when they were training full-time in their teens, it's pretty incredible," he noted.Looking ahead, the Australian swimmer has set his sights on future Olympic Games. "I've still got my eyes on LA, I definitely have my eyes on the home Games here in Brisbane, and so I'll just keep at it every year and just take it one step at a time," McEvoy stated, emphasizing his commitment to continue pushing boundaries with his unique training philosophy.
