A recent study has found that sperm deteriorates over time as it remains in the body, leading researchers to suggest that men who ejaculate more frequently may have better sperm quality.The study, which combined 115 human studies involving nearly 55,000 men and 56 studies on non-human species, found that the longer men went without sex, the more their sperm showed signs of DNA damage and oxidative stress, and the more tests rated the sperm as less viable and poorer swimmers.The World Health Organization (WHO) recommends men abstain from ejaculating for two to seven days before giving sperm for fertility tests or IVF, but the guidelines were designed to obtain the highest sperm count rather than prioritizing the best quality sperm.Dr. Krish Sanghvi, lead author of the study, said: "In men, the negative effects we found on sperm DNA damage and oxidative damage were large-ish, so we are confident that this is a biologically meaningful and important effect."The study's findings suggest that clinicians and couples should reconsider whether long abstinence is always good, as abstinence leads to deterioration in sperm quality.For couples trying to conceive naturally, a balance between quantity and quality needs to be struck, with abstaining for too long or too little potentially affecting sperm quality and quantity.Experts say that for assisted reproductive technology (ART) treatments, it's having the freshest, most healthy sperm that is probably more important, and that the two to seven days abstinence rule may not be as crucial when IVF treatment is taking place.

Matt Brittin, Google's former top executive in Europe, has been selected as the next director general of the BBC. Brittin, who stepped down as Google's president in Europe, the Middle East, and Africa last year, will replace Tim Davie at a critical juncture for the corporation. The 57-year-old's appointment was confirmed after a BBC board discussion on Thursday. Brittin, a former Olympic rower and Doctor Who fan, is seen as a substantial figure capable of diving straight into crucial government talks over the renewal of the BBC's royal charter. However, his lack of editorial experience has been noted by insiders, who worry about his ability to deal with the periodic crises that occur at the corporation. The BBC is now expected to create the role of deputy director general to support Brittin, with a new head of BBC News also to be appointed. Brittin expressed his excitement about the role, stating: “Now, more than ever, we need a thriving BBC that works for everyone in a complex, uncertain and fast-changing world.” Samir Shah, the BBC's chair, praised Brittin's experience, saying he had “deep experience of leading a high-profile and highly complex organisation through transformation”. The appointment comes after some early favourites for the role dropped out or declined to apply amid concerns that scrutiny and political attacks aimed at the BBC have made leading it one of the hardest jobs in public life. Brittin's lengthy career at Google will also be significant in his new job, particularly as the BBC lays out plans to save considerable costs using a new tech division and forges a new relationship with YouTube, which is owned by Google. The licence fee model is also under pressure, with more people opting not to pay.

A landmark jury verdict has found Meta and YouTube liable for deliberately designing addictive products that harmed a young user, KGM. The jury ruled that the tech companies were both negligent and failed to provide adequate warnings about the potential dangers of their products.The plaintiff, KGM, testified that she became addicted to YouTube at age six and Instagram at nine, which she claimed had deleterious effects on her wellbeing. By age 10, she said she had become depressed and was engaging in self-harm as a result. Her social media use allegedly caused her to have strained relationships with her family and in school.The jury awarded KGM $6m in damages, with Meta to pay 70% and YouTube the remainder. This lawsuit, over social media's alleged harm to young people, was the first of its kind to go to trial.KGM's lawyers argued that the companies' features, such as infinite scrolling and video autoplay, were designed to keep people on the apps and made the products addictive. The plaintiffs' arguments mirrored those brought against big tobacco in the 1990s, focusing on the addictive qualities of social media and the companies' public denial despite knowledge of their products' harms.Meta and YouTube have consistently denied wrongdoing and plan to appeal the verdict. A YouTube spokesperson said the video service was a responsibly built streaming platform, not a social media site. Meta said KGM's mental health issues were brought on by a difficult home life and social media use was not to blame.This trial is the first in a consolidated group of cases brought in California against Meta, TikTok, YouTube, and Snap on behalf of more than 1,600 plaintiffs. The next bellwether case is scheduled to go to trial in July.

Tracy Kidder, an award-winning narrative nonfiction writer, has passed away at the age of 80. Kidder was known for his ability to transform unlikely subjects into bestsellers, captivating readers with his in-depth research and storytelling skills. Throughout his career, Kidder immersed himself in various worlds, producing richly researched books on topics that may not have seemed like light reading. His work included The Soul of a New Machine, which explored the inner workings of a fledgling computer company in Silicon Valley and earned him the Pulitzer Prize and National Book Award in 1981. Kidder's other notable works include Among Schoolchildren, which highlighted the dedication of an inner-city teacher in Holyoke, Massachusetts, and Old Friends, which chronicled the lives of two friends in a nursing home. His book Mountains Beyond Mountains, about a doctor's efforts to bring healthcare to Haiti, introduced his work to a new generation of readers and inspired numerous universities to add it to their reading lists. Kidder's approach to storytelling was rooted in his belief that small things can have a significant impact. He avoided focusing on his personal interests, such as fishing or baseball, to maintain his objectivity and enthusiasm for his subjects. Kidder saw himself as a storyteller, not a 'literary journalist' or 'creative nonfiction' writer, and believed that nonfiction should not be limited by traditional techniques. Born in New York City in 1945, Kidder attended Harvard University and served in Vietnam, where he documented his experiences in My Detachment, a memoir that offered insights into the lives of support troops.

In a significant move, Meta has been fined $375m in a landmark case, highlighting the growing scrutiny of big tech companies. The fine, reported by The Guardian, marks a major development in the ongoing debate over tech regulation and accountability.The case, which involved multiple authors including Lucy Hough, Katie McQue, Bryony Moore, Ryan Ramgobin, and Zoe Hitch, underscores the increasing pressure on tech giants to adhere to regulatory standards. As the digital landscape continues to evolve, this ruling sets a precedent for future cases involving big tech.

Richie Garcia, a former major league umpire, has voiced his concerns about the impact of robot officials on human umpires in Major League Baseball. The Automated Ball-Strike Challenge System, set to debut in 2026, allows teams to challenge strike zone decisions using a system based on 12 Hawk-Eye cameras.Garcia believes that this technology will lead to the humiliation of umpires, stating, "Nobody likes to be humiliated in front of 30,000, 40,000 people." He argues that Major League Baseball is essentially saying it doesn't trust the umpire's strike zone and will instead rely on a system operated by "some computer geek" with a PhD in physics.Despite criticism, umpires have shown increased accuracy in recent years, with an accuracy rate of 92.83% last season, down from an average of 10.88 missed calls per game. The introduction of ABS aims to further reduce errors, with each team getting two challenges per game.Umpires have mixed views on the technology, with some seeing it as a way to correct egregious pitches and others concerned about the mental impact of constant evaluation. Spring training test results showed varying success rates among teams, with Philadelphia and Chicago Cubs performing well in challenge success rates.

A recent Australian Senate inquiry has concluded that the country's climate change and energy 'information ecosystem' is fuelling conflict in communities, with misinformation and disinformation confusing the public, slowing renewable energy projects, and undermining policy responses to the climate crisis.The inquiry's final report, released on Tuesday evening, recommended that the government do more to make tech companies liable for 'psychosocial harms' spread on their platforms. It also suggested strengthening media literacy through the national curriculum and greater oversight when corporations engage with classrooms.The committee recommended more funding for research into mis- and disinformation, with a funding model to be developed for an independent effort to 'track hidden digital influence systems'. The Australian government should also sign a UN declaration, launched in Brazil in 2025, promising a series of actions aimed at combating climate mis- and dis-information.The use of artificial intelligence by groups looking to block progress on climate change was likely to further threaten the integrity of information the public received, the inquiry heard. The committee's Greens and Labor members endorsed the report, but some members felt it did not go far enough in addressing the issue.The inquiry's findings have significant implications for Australia's renewable energy future and its ability to address the climate crisis. As climate disinformation continues to evolve into a national security challenge, the Australian government must take urgent action to protect the integrity of information and promote a safe climate future.

The UK's ambition in quantum computing is being backed by sustained investment in people and fundamental science, with a focus on building a strong foundation for the sector. UK Research and Innovation (UKRI) has been instrumental in supporting hundreds of academics and building the infrastructure needed for the industry to thrive.In the last 10 years, UKRI's councils have made significant investments in physics research, including support for 100 PhDs in quantum technology launched in 2024, quantum computing industrial doctorate awards, and funding 14 early-career fellows in the last 18 months.The investment is paying off, with the quantum sector showing promising growth and potential to create 100,000 jobs in the next 20 years. The government has signalled its recognition of the opportunities in quantum computing with a further £1bn procurement programme, making the UK one of the most exciting and well-supported places in the world for quantum computing researchers, companies, and students.Prof Charlotte Deane, UK Research and Innovation, highlights that the UK's advantageous position in quantum has emerged through sustained long-term public investment into fundamental physics research projects, and the best people, infrastructure, and partnerships.

The relationship between dogs and humans has long been a subject of fascination, and recent groundbreaking research has shed new light on the origins of this enduring bond. Published in the journal Nature, the study reveals that the genetic evidence for domestic dogs dates back an astonishing 15,000 years, a full 5,000 years earlier than previously thought.Ancient DNA analysis of dog remains has provided unprecedented insight into the early days of dog domestication. The oldest specimen, a 15,800-year-old dog buried alongside human remains in Anatolia, Turkey, and a 14,300-year-old jawbone from Gough's Cave in Somerset, England, are key findings that have helped researchers reevaluate the timeline of dog domestication.According to Dr. Lachie Scarsbrook of Ludwig Maximilian University of Munich, the study suggests that dogs with diverse ancestries already existed across Eurasia 15,000 years ago, from Somerset to Siberia. This raises the possibility that domestication occurred during the last ice age, more than 10,000 years before the emergence of other domestic plants and animals.The research, conducted by international teams, analyzed DNA from bones at various sites, including Gough's Cave, Pınarbaşı in Turkey, and two sites in Serbia. Advanced sequencing techniques allowed researchers to piece together tiny fragments of ancient DNA, enabling clear species identification for the first time.Key findings include:Dogs were widespread across Europe and western Asia by at least 14,000 years ago.Isotopic analysis revealed dogs consumed a diet rich in fish, matching the local human diet in Turkey.Evidence of deep emotional bonds between humans and dogs, including the burial of puppies over human remains.The study's authors suggest that dogs may have increased hunting efficiency or served as an early warning system against predators. The genetic relationship between dogs across sites implies that they may have spread rapidly across Europe, possibly through trade between unrelated groups.As Prof. Laurent Frantz notes, the fact that people exchanged dogs so early suggests these animals must have been important, serving purposes beyond being pets. The research provides a fascinating glimpse into the ancient partnership between humans and dogs, highlighting the significance of this bond in human history.
