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.

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.

Lisa Kudrow reprises her role as Valerie Cherish in the third season of 'The Comeback', a character often compared to Steve Coogan's Alan Partridge. Both are narcissistic figures clinging to past showbiz successes. The show initially gained acclaim for its satirical take on the entertainment industry. This season, Cherish is offered a lead role in a new sitcom called 'How's That?', which is secretly written by an AI program. The use of AI in comedy writing is a key concern, especially following the 2023 US writers' strikes. However, the show fails to effectively satirize this concept, instead opting for a more sentimental approach. The Comeback's earlier seasons were praised for their meta approach, blending reality TV and mockumentary styles. However, the latest season struggles with its format, frequently switching between mock-doc and traditional sitcom modes without clear justification. Cherish, once portrayed as a sharp-elbowed has-been, has evolved into a reformed character. She is now universally praised by those around her, making her less relatable and less humorous. The show's attempts at humor fall flat, with the AI-generated scripts producing generic and unfunny gags. The season concludes as a heartfelt paean to traditional comedy, but its lack of humor and toothless satire leave little confidence in its future. The show's shift towards sentimentality over satire is a significant disappointment.

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.

The conflict between the US, Israel, and Iran has escalated with a series of attacks on Iranian cities, including the capital Tehran, and other locations such as Tabriz, Isfahan, and Karaj. These attacks occurred even as US President Donald Trump claimed that Washington was engaged in productive conversations with Tehran to end the war.Iranian media reported that Israeli-US strikes targeted two gas facilities and a pipeline, hours after Trump postponed planned attacks on power infrastructure. The attacks resulted in partial damage to facilities in central Iran, including a gas administration building and a gas pressure regulation station in Isfahan.A leading scholar and professor at a science university in Tehran, Saeed Shamaghdari, was killed alongside his two children in an attack on his residence north of the capital. Iran's English-language news channel Press TV identified Shamaghdari as a teacher at the engineering department of the Iran University of Science and Technology.The head of Iran's emergency service, Jafar Miadfar, reported that 208 children have been killed since the war began on February 28, with 168 of them dying in the US missile strikes on a girls' school in Minab city. Rights groups have called for an investigation into the Minab attack as a potential war crime.More than 1,500 civilians have been killed across Iran, according to the Iranian government. The US-Israel war on Iran has expanded across the Middle East, leading to a spike in oil prices and triggering a global energy crisis.Despite the escalation of violence, Iran's Foreign Minister Abass Araghchi has held calls with several countries, including Egypt, Pakistan, and Oman, in an attempt to open a diplomatic channel. However, senior Iranian officials have denied that Iran is engaged in talks with the US, contradicting Trump's claims of productive conversations.European Commission President Ursula von der Leyen has emphasized the need for a negotiated solution to the conflict, warning that the situation is critical for energy supplies and condemning Iran's efforts to block energy exports through the Strait of Hormuz.

A second set of mountain gorilla twins has been born in Virunga National Park in the Democratic Republic of the Congo (DRC), marking what conservationists are calling an extraordinary event for these endangered primates.Just two months after twin mountain gorillas were discovered by rangers in the Virunga massif in eastern DRC, another rare twin birth has been found by park wardens. This time, an infant male and female have been spotted in the Baraka family, a troop of 19 mountain gorillas that roam the region's high-altitude rainforests.Park rangers have placed the young primates under additional monitoring to help them through the critical initial months, as the infants face significant challenges to becoming fully grown adults. Twins are extremely rare in mountain gorillas, accounting for less than 1% of births, and place extra demands on the mother.The gorilla subspecies, found in only two isolated pockets of the Virunga massif and the Bwindi Impenetrable National Park in southwest Uganda, has high rates of infant mortality, with about a quarter falling victim to disease, trauma or infanticide.In January, Virunga National Park announced that a female mountain gorilla called Mafuko had given birth to twins. The infant males are now 11 weeks old and said to be thriving, with other gorillas in the troop taking extra care of the mother to support her caregiving, according to rangers. Park authorities believe that twin births are more likely when females are in particularly good physical condition.Jacques Katutu, the head of gorilla monitoring at Virunga, said: "Two instances of twin births within three months is an extraordinary event and provides another vital indicator that dedicated conservation efforts, which have continued despite the current instability in eastern Congo, continue to support the growth of the endangered mountain gorilla population within Virunga National Park."Specialist veterinary care has played a leading role in the revival of the subspecies. In Rwanda, Uganda and the DRC, organizations such as the Gorilla Doctors have prevented dozens of deaths by helping animals affected by human behavior, such as by releasing gorillas accidentally caught in poachers' traps. One study attributes half of the mountain gorillas' population increase to the vets.Barely 250 mountain gorillas were left in the 1970s, and many thought the animals faced extinction. Decades of intense conservation work helped population numbers surpass 1,000 in 2018, and conservation authorities have since downgraded the subspecies' status from critically endangered to endangered.The DRC section of the Virunga mountain range remains one of the most dangerous places in the world for wildlife rangers. Over the past 20 years, more than 220 rangers have been killed in the park, where rebel groups such as M23 and other militias, as well as bandits, operate with impunity.
