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.

The UK government's recent announcement to make significant cuts to direct aid to Africa and the Middle East has been met with deep disappointment. This move is seen as a moral dereliction of duty, betraying the world's most marginalised, and a false economy that will bring greater instability to the world and make people less safe. The cut in aid to 0.3% of gross national income (GNI) from 2027 breaks Labour's 2024 manifesto pledge to restore development spending at the level of 0.7% of GNI “as soon as fiscal circumstances allow”. The UK is making the steepest proportion of aid cuts among G7 nations. As James Mattis, Donald Trump's defence secretary, once said: “If you don’t fund the state department fully, then I need to buy more ammunition ultimately.” This highlights the shortsightedness of cutting aid, which could lead to more conflict, famine, and persecution. The UK itself benefits materially from these investments. The recent inquiry by the all-party parliamentary group on global health and security on international health worker recruitment highlights the extent to which the NHS and wider economy rely on the skills, expertise, and partnerships rooted in the global south. The UK has saved £14bn in training costs through international recruitment and continues to depend on globally trained health professionals. Investment in global vaccination, disease surveillance, and research helps stop outbreaks before they spread internationally and place pressure on health systems. Preventing disease at source is one of the smartest investments we can make to protect patients in Britain. The situation in Somalia, on the edge of famine, underscores the importance of sustained investment in global development. Two consecutive failed rainy seasons have left 6.5 million people in crisis, more than double the number a year ago. The UK's humanitarian relief in Somalia is welcome, but the scrapping of nature funding and cuts to climate aid risk compromising its own strategy of preventing crisis before it takes hold.

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.

Wales coach Craig Bellamy has urged his team to stay calm and focused ahead of their crucial World Cup playoff semi-final against Bosnia and Herzegovina on Thursday. Drawing inspiration from Usain Bolt's approach to high-pressure situations, Bellamy emphasized the need for his players to remain relaxed and composed under pressure.Bellamy, who has been in charge of Wales for nearly two years, believes that his team has the ability to perform at their best when they are calm and focused. He cited their seventh-ranked possession statistics in European countries since he took over, highlighting their ability to control games. The team has also shown resilience, with Ethan Ampadu deputizing for injured captain Ben Davies.The prize for success in the playoff is a spot at successive World Cups, which would not only bring prestige but also a significant financial boost and a positive impact on grassroots football in Wales. Bellamy is aware of the challenges posed by Bosnia and Herzegovina, having researched their background, culture, and squad composition. He noted that 11 of their 35-man squad were born in Bosnia, while the others come from the Netherlands, Germany, and Sweden.Bellamy expressed his confidence in his team's abilities, stating that “there won't be any regrets” regardless of the outcome. He emphasized that his team will give their all and that he is prepared for all possible outcomes. The coach also highlighted the importance of enjoying the experience and not letting pressure get to them, saying, “If you can't enjoy this and you only feel pressure, you ain't made for elite sport.”Wales' last experience in a playoff ended in pain, with Wojciech Szczesny being Poland's hero. However, Bellamy is determined to build a team capable of competing for top spot in qualifying and avoiding the need for playoffs in the future.

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.

Israel has been accused of using white phosphorus in southern Lebanon, a move that has reignited concerns over the country's adherence to international laws of war. Human Rights Watch (HRW) researchers have verified and geolocated images showing airburst white phosphorus munitions exploding over residential areas in the southern Lebanese town of Yohmor.The use of white phosphorus, a chemical substance that ignites when exposed to oxygen and burns at up to 800C, is controversial when used over civilian areas due to its potential to ignite fires, cause serious burns, and emit toxic fumes. Military forces often use it as a smokescreen, but its use in populated areas raises significant ethical and legal questions.Over 800,000 Lebanese people have been displaced from the region following Israeli forces' orders to leave, and many more uses of white phosphorus may have gone undocumented. Researchers have documented nearly 250 uses of white phosphorus by Israeli forces between October 2023 and November 2024, with 39% of these uses occurring in residential areas.The environmental impact is also significant, with over 2,000 hectares of southern Lebanese countryside burned, including dense forests and agricultural lands. The use of white phosphorus can lead to long-term soil contamination, reducing microbial diversity and agricultural productivity.An Israeli military spokesperson has cautioned against making factual determinations based on visuals alone, while Israel's ambassador to the UN has stated that the country takes steps to minimize civilian casualties. However, allegations of war crimes and the use of prohibited weapons continue to mount, highlighting the need for further investigation and accountability.

Hong Kong police have been granted the authority to require individuals suspected of violating the city's national security law to provide passwords to their mobile phones or computers. This measure, which took effect on Monday, is part of the national security law imposed by Beijing in 2020. The new provisions empower police to require a person under investigation suspected of endangering national security to provide any password or decryption method for electronic devices and to provide the police “any reasonable and necessary information or assistance”. Refusing to comply could lead to up to one year’s imprisonment and a fine of up to 100,000 Hong Kong dollars ($12,768), while providing false or misleading information could bring up to three years’ imprisonment and a fine of up to 500,000 Hong Kong dollars ($63,840). The imposition of the 2020 national security law, supplemented by a second component in 2024, has led to a marked decline in civil liberties in the former British colony returned to China in 1997, according to human rights advocates. The new amendments have sparked concerns over the erosion of Hong Kong's autonomy and its status as an international financial and business centre. Urania Chiu, a law lecturer in the UK researching Hong Kong, said the new provisions interfered with fundamental liberties, including the privacy of communication and the right to a fair trial. “The sweeping powers given to law enforcement officers without any need for judicial authorisation are grossly disproportionate to any legitimate aim the bylaw purports to achieve,” Chiu told the Reuters news agency. A Hong Kong government spokesperson said the amended rules conform to the city’s mini-constitution, the Basic Law, and its human rights provisions, and “will not affect the lives of the general public or the normal operation of institutions and organisations”. According to the Security Bureau, a total of 386 people have been arrested for national security crimes so far, with 176 people and four companies convicted.
