Generic version of a drug already on the market, which can suppress and prevent HIV, would still yield 30% profit if the current price was slashed, researchers sayA new drug described as the closest we have ever been to an HIV vaccine" could cost $40 (31) a year for every patient, a thousand times less than its current price, new research suggests.Lenacapavir , sold as Sunlenca by US pharmaceutical giant Gilead, currently costs $42,250 for the first year. The company is being urged to make it available at a thousand times less than that price worldwide. Continue reading...

There are stabs of the same fear that made The Beast fascinating, but this tale of a bored teenager in a scary, affectless future is too unfocusedProminent French film-makers are supported by their national industry and even their lockdown projects have been received with respectful attention. Earlier this year Olivier Assayas's autofiction Hors du Temps, or Suspended Time, premiered in Berlin - a dreamy Covid-era indulgence that he just about got away with. Now we have a chance to see Bertrand Bonello's musing sketch Coma: a lockdown essay that preceded his brilliant futurist film The Beast, with many of the same ideas and tropes.Coma broods on a scary, affectless future in which humanity will evolve away from the primacy of love and selfhood, and in which sexuality and violence will then be prominent as a symptom of the need to feel something, anything. As so often, Bonello sees human beings as mere dolls or puppets; stuffed mammal-shapes whose supposed individuality is a preposterous fiction. Here, a teenage girl (Louise Labeque) mopes impassively in her bedroom, driven half-mad by lockdown boredom; the film's title hints at the inert hibernation we all went through. Continue reading...

Last week, five supporters of the Just Stop Oil climate campaign who conspired to cause gridlock on London's orbital motorway were sentenced to lengthy jail terms by a judge who told them they had crossed the line from concerned campaigner to fanatic'.

Young people are evaluating good and bad life decisions on a scale and seeking input from others. To philosophy experts, it sounds familiarYou can count calories, steps, streams of your favorite song - and now, you can assign a number to how cool you are.

Botanical gardens lost 400 trees during 2022 drought, prompting research into potential loss in coming decadesMore than half of the tree species at Kew's Royal Botanical Gardens are at risk of death because of climate breakdown, a study by the public body has found.Founded in 1840, Kew Gardens says it houses the largest botanical collection in the world. During the drought of 2022, the botanical gardens in south-west London lost 400 of its trees. Scientists at Kew decided they should map and chronicle the climate risk to the trees to see how many could feasibly be lost to the changing weather in the coming decades. Continue reading...

It's easy enough to get lured into adopting a brittle persona, but there are other ways to live your lifeMy work used to land in the form of harsh clacking on a titanium-reinforced MacBook, but these days I prefer to write in a pale blue suedette notebook that was given to me by a relative a few Christmases ago. It is an object that until recently I had kept at the back of a drawer, fearing it would seem too sappy a thing for a serious writer to own.It forms part of a new tendency in my life towards softness - the quality of being gentle to the touch, sensual and pliable, but also receptive, yielding and adaptive. As an antidote to our digitally enhanced lives, which can appear to be cold and hyper-real, softness seems to be on the rise. There is the girlhood aesthetic", which is the nostalgic use of bows, frills and smock dresses. In literature, Arrangements in Blue by Amy Key chronicles the author's journey to creating a soft and cosseting home environment, while the hugely popular Milk Fed by Melissa Broder is a love letter to fleshiness and abundance.

The evolutionary expert discusses the triumphs and challenges of the groundbreaking research on Galapagos Islands finches she undertook with her husband, PeterStudying Darwin's finches has been the life's work of the renowned British evolutionary biologists Rosemary and Peter Grant. For several months every year for 40 years, the husband-and-wife team visited the Galapagos Islands in the eastern Pacific to meticulously track the fate of thousands of finches on two small islands there. The Grants demonstrated that evolution by natural selection can be observed in the wild in real time: they were the first to see and measure it in action in nature. One Step Sideways, Three Steps Forward is Rosemary Grant's new memoir. It reflects on her far-from-straight path to becoming a biologist, living with a family on the Galapagos - for 10 years the scientists' two daughters accompanied them - and the joy of sharing ideas with her partner. Rosemary, 87, is senior research biologist, emeritus at Princeton University in New Jersey. The book comes ahead of a new edition of 40 Years of Evolution - the Grants' classic account of their study of the finches - due out later this year.The Galapagos are famous for their unusual and unique species including giant tortoises, marine iguanas and flightless cormorants. But what's the Charles Darwin connection?

Don't put your faith in the 10,000-hour rule - some athletes are born with talents the rest of us will never haveStefan Holm was told he was too short to be a high jumper. But by the time he won Sweden a gold medal in the 2004 Olympics, he had honed himself into the perfect projectile. It was the result of a 15-year obsession: his whole life had been pulled into alignment with this goal. If he wanted to stop on page 225 of a book, he would push himself to page 240, in order to train his mind to overshoot. It's all about your 10,000," he told David Epstein, author of The Sports Gene. There had been jumpers who had beaten him when he was young, and where were they now?But in 2007, entering the world championships in Japan as the favourite, he faced an unknown opponent: Donald Thomas, from the Bahamas. Thomas had begun jumping just eight months previously, on a whim after a bet, and admitted he found the high jump kind of boring". He had slacked off training - his form was all over the place - and his coach couldn't even persuade him to wear the right kind of shoes. But he had one big advantage: an achilles tendon that could store just a bit more elastic energy than everyone else's. That year, Thomas sprang awkwardly over the bar to victory. Continue reading...

Research helping mice reach a ripe old age is of little use to humans if it boosts longevity but not healthspansProspects for extending lifespans have generated some striking headlines in recent weeks. Tantalising drug lets mice live longer but retain youthful looks," the Times announced. Anti-ageing drug is holy grail' of cancer fight," claimed the Telegraph.Nor is the agent of this media adulation - antibodies that block the action of the inflammatory chemical IL-11 - the only wonder anti-ageing medication to make news over the past few months. In March, researchers announced that, by properly balancing two types of immune cells, they had managed to improve the ability of elderly mice to fight off viral infections and so live longer. This came on top of research last year from another group revealing they had used injections of the drugs dasatinib and quercetin to rejuvenate the hearts of mice and make them less frail.

Offensive term to be replaced as first step towards more changes in unprecedented reform of nomenclature rulesScientists have voted to eliminate the names of certain plants that are deemed to be racially offensive. The decision to remove a label that contains such a slur was taken last week after a gruelling six-day session attended by more than 100 researchers, as part of the International Botanical Congress, which officially opens on Sunday inMadrid.The effect of the vote will be that all plants, fungi and algae names that contain the word caffra, which originates in insults made against Black people, will be replaced by the word affra to denote their African origins. More than 200 species will be affected, including the coast coral tree, which will be known as Erythrina affra instead of Erythrinacaffra. Continue reading...

Researchers call on the government to settle dispute, which they say is impeding groundbreaking researchResearchers have called on the government to step in to settle a dispute preventing them from fully exploiting the world's largest store of human genetic data. The scientists say they are unable to access patients' data, held by British GPs, despite a decade of requests, and that the refusal is impeding the development of new diagnoses and treatments.Prof Naomi Allen, chief scientist of UK Biobank, told the Observer it had sequenced genomes of more than 500,000 volunteers and collated a host of other data about them. However, it was still prevented from accessing their primary health care data held by their GPs. Continue reading...

Scientists have long known the mental and creative benefits of the flow state, in which total absorption in an activity banishes anxiety. But what causes it, and how can we achieve it?As a professional ballet dancer, Julia Christensen knew the flow state well: a total absorption in her body's movements, without the constant chatter that typically accompanies our waking lives. The hours could fly by without her even registering the time that had passed.A back injury put an end to her career, and alongside the many other life changes that this brought on, she found herself missing the mental calm that had accompanied her practice and performances. I became aware that I couldn't control my thoughts," she says. And I'd never had to deal with that before." Continue reading...

Researchers unsure why animals turn up with items such as socks and gloves - but agree pilfered items are not presentsThe thieves went for particular items. Day after day, they roamed the neighbourhood and returned home to dump their loot. Before long they had amassed an impressive haul: socks, underpants, a baby's cardigan, gloves and yet more socks.It's not unusual for cats to bring in dead or petrified mice and birds, but turning up with random objects is harder to explain. Researchers suspect a number of causes, but tend to agree on one point: the pilfered items are not presents. Continue reading...

Citizens were failed by a lack of planning, and Lady Hallett wants a better system to be built fastCitizens of all four nations of the UK were failed by politicians and officials who neglected to prepare properly for a pandemic or other civil emergency. Former UK health secretaries Jeremy Hunt and MattHancock did not update or improve an inadequate pandemic strategy from 2011, that was geared towards flu rather than a novel virus. Resources that did exist were constrained" by funding and, after 2018, redirected towards Brexit planning. Ministers were guilty of groupthink and did not make effective use of external experts or challenge scientific advice. The possibility of a lockdown was never seriously considered. Nor was enough attention paid to the likelyimpact of a pandemic on vulnerable groups.These highly critical conclusions from the first module of the Covid inquiry are a landmark moment in the process of national reckoning being overseen by Heather Hallett. This is the first time that relatives of the 230,000 people who died of Covid have seen their anger about official failures, both before and during the pandemic, endorsed in such an authoritative way.

The UK must never succumb to such shocking complacency again. Planning for the next pandemic must start nowIn 2002, Sars, a dangerous coronavirus, spread across the world with a fatality rate of around 10%. Although it was contained relatively quickly, east Asian countries learned from this experience and updated their pandemic preparedness plans. Their governments wanted to be ready if the virus returned. On the other side of the world, the UK didn't react or adapt. Complacency was at play, especially with the assumption that Britain was one of the most prepared countries in the world for a pandemic.The consequence, as Lady Hallett's first report from the Covid inquiry notes, is that the UK government failed in its basic responsibility to its citizens of keeping them safe. The UK had too many preventable deaths, not only from Covid, but also from the shutdown of health services and a long lockdown that would have been unnecessary had public health systems been in place.Prof Devi Sridhar is chair of global public health at the University of Edinburgh Continue reading...

Multivitamins are cheap, convenient, and provide a little bit of reassurance if our diet isn't quite as healthy as we'd like. But a recent study of nearly 400,000 people spanning 20 years found they didn't help users live longer, and in fact appeared to show a 4% increased mortality risk.

The FDA's recent rejection of MDMA isn't surprising. Too many advocates are trying to frame psychedelics as a miracle drugEarlier this month, an advisory panel rejected MDMA-assisted therapy for PTSD, possibly dooming US Food and Drug Administration (FDA) approval of the drug commonly called ecstasy. In a public meeting alongside FDA staff, panel members said that the research neither adequately accounted for abuse risks nor proved the drug's efficacy in combination with psychotherapy.This decision dealt a major blow to Lykos Therapeutics, the for-profit public benefit corporation of the non-profit Multidisciplinary Association for Psychedelic Studies (Maps), which sponsored the trials. More broadly, the rejection has been described as a drastic setback for the psychedelic movement as a whole. For several years now, it seemed that greater acceptance and new legal spaces for psychedelics were a certainty. Then, scientists appeared at the FDA hearing and everything went dark.

A new report suggests self-declared night owls tend to have higher cognitive scores. So please can we now ditch the lazy and undisciplined stereotypes?My fellow night owls, grab a strong cup of coffee and gather around: I have great news. For a long time, our kind has been unfairly maligned. Stereotyped as lazy and undisciplined. Told we ought to be morning larks. Advised to go to bed early so we can wake before 5am and run a marathon before breakfast like all high-flyers seem to do. Now, however, we are having the last laugh. Science has officially crowned us superior to our early-rising brethren.OK, it may be a tad more complicated than that. A study published last week, which you may have already seen while scrolling at 1am, suggests that staying up late could be good for brain power. Is this study a thinly veiled PR exercise conducted by a caffeine-pill company? Nope, it's legit. Research led by academics at Imperial College London studied data on more than 26,000 people and found that self-declared night owls' generally tend to have higher cognitive scores". And we are talking quite a lot higher. Evening types ... scored about 13.5% higher than morning types in one group and 7.5% higher than morning types in another group", according to a write-up of the study. Continue reading...

Yes, with the help of AI, I could play Juliet or go on Naked Attraction. But wouldn't something be lost in the process?In my long life, I have had to get my head around massive technological changes. When I was young, I relied on my knowledge of the times tables, and counting on my fingers, to add up. It took me weeks to master the revolutionary Amstrad word processor. The only phone was in the hall, calls strictly rationed by my father. Over the years, I have braved the exasperation of my grandchildren, and now Google, Zoom and unmute with the best of them.But the latest incomprehensible technical revolution has me flummoxed. I seriously fear I will not have mastered artificial intelligence before passing on to a world where, hopefully, the most I will have to cope with are some old-fashioned golden gates, and there will be a nice angel to explain how they work.Sheila Hancock is an actor and a writer Continue reading...

Subjects' performances of songs by Adele, Mariah Carey or from Frozen shown to peers to assess responsesWere scientists to concoct an experiment that was all but guaranteed to unleash full-on, cheek-reddening embarrassment, then filming adolescents singing Let It Go from Frozen and playing back their performance might well do the job.And so to researchers at the University of Amsterdam who invited dozens of young volunteers into the lab before breaking the news as to what was required. In front of a camera, and without the benefit of a shot or two, they were asked to sing the Arendelle anthem or another choice track, before they and others watched the rendition back from inside a brain scanner.

Pharmacologist whose research into tamoxifen helped many women with breast cancer to live longerIn the 1970s only 40% of women diagnosed with breast cancer could expect to survive for 10 years or more. Today that figure is over 75%. Screening and early diagnosis have played a part, but one of the key reasons for the improvement is the drug tamoxifen, which massively reduces the risk of cancer recurring after surgery.The British-American pharmacologist Craig Jordan, who has died aged 76, was the first to show that tamoxifen could stop tumours growing by blocking the female hormone oestrogen from locking on to cells in the breast at specific sites called oestrogen receptors.

For children with ADHD, getting the help they need depends on being correctly diagnosed. As a doctor, I have seen how tricky and frustrating a process that can beLate last summer, in the waiting room of a children's mental health clinic, I found Daniel, a softly spoken 16-year-old boy, flanked by his parents. He had been referred to the clinic for an assessment for attention deficit hyperactivity disorder (ADHD). As we took our seats on the plastic sofas in the consulting room, I asked him to tell me about the difficulties he was having. Tentatively, his gaze not leaving the floor, he started talking about school, about how he was finding it impossible to focus and would daydream for hours at a time. His exam results were beginning to show it too, his parents explained, and ADHD seemed to run in the family. They wanted to know more about any medication that could help.I had just begun a six-month placement working as a junior doctor in the clinic's ADHD team. Doctors often take a temporary post before they formally apply to train in a speciality. Since medical school I had always imagined I would become a psychiatrist, but I wanted to be sure I was making the right choice. Continue reading...

More than sadness, hatred or grief, rage is something that we shut away or flee. That endangers our relationships, our happiness - and our safetyI have wanted to write about anger for some time. As I sat down to begin this column, a recent psychoanalysis session came to mind. I was telling my analyst about something that might have made me angry - but instead, as I spoke to her, I experienced a sudden wave of irresistible sleepiness. I described this sudden onset of fatigue, as I felt the overwhelming weight of my eyelids and gave up trying to keep them open, so losing the thread of what I had just been talking about. Perhaps you are sending your anger to sleep," my analyst said.The more patients I treat in psychotherapy, and the more psychoanalysis I receive as a patient, the more I think that anger is often the hardest feeling to feel. More than sadness, more than love, more than hatred, more than grief, anger is repressed, or acted out, or drunk or drugged away, or killed off, or sent to sleep. Anything, it can seem, but allowed into our minds and felt. Continue reading...
