Research shows wearing a 400 headset for just a few minutes a day may ease the misery, negativity and depression that can accompany a failed relationship. Continue reading...
Self-care: why looking after No 1 isn’t always best for your wellbeing
A range of scientific studies point to clear physical and mental benefits of supporting friends and family. And the deeper the engagement, the greater the feelgood factorLike many people, I find that stress transforms me into a nasty combination of Oscar the Grouch and Scrooge McDuck. The more pressure I am under, the more irritable I feel - and the less generous I become. I partly blame our culture. I've read enough wellness advice to know that I need to prioritise my own needs over other people's. And so, when I feel under pressure, I have often made it a habit to practise small indulgences aimed at restoring my mental equilibrium, while insulating myself from all but the most essential social commitments.Having read the latest psychological research, I can't help but wonder if this attitude only exacerbates my bad mood. A wealth of new studies has shown that being kind to others is often the most effective means of suppressing the physiological and psychological stress response. Whether we are giving our time to a charity, paying it forward" in a coffee shop, or providing emotional succour to a friend in need, altruism can boost our wellbeing in ways that we simply do not experience from treating ourselves. Other-care, it seems, is often one of the best forms of self-care. Continue reading...
Prof Arturo Casadevall: ‘It is hubris to think a fungal pandemic can’t happen to us’
Could a fungus trigger a Last of Us-style apocalypse? The author of What If Fungi Win? says despite dangers, the organisms are of great use to scienceArturo Casadevall is a professor of molecular microbiology and immunology at the Johns Hopkins Bloomberg School of Public Health. He has spent four decades investigating how fungi can both improve and devastate life as we know it. His new book, What If Fungi Win?, charts how we might overcome the rising threat.What first fascinated you about fungi?
When our young son died, we decided to build him a boat
Wild Cat Island had always held a special place in the imagination of our son, so after his funeral we chose to try and send him on one last journeyFamously, Windermere is the setting of the children's adventure story Swallows and Amazons by Arthur Ransome, and it's also one of our son Torin's favourite books. It appealed to his own love of adventure, mischief and all things piratical. Along with his little sister, Lowri, we embarked upon many canoe adventures together on the River Dart in the summer months, spotting wildlife and playing pirates with other boats. Torin - which means chief - was always ship's captain, of course, because the children from the story often tussled for the position. Torin also loved practical jokes. His favourite was the whoopee cushion, normally hidden very indiscreetly on a seat where you would be ordered to sit down with great anticipation and stifled giggling.Torin was born with a rare form of life-limiting, mitochondrial disease. After many lengthy admissions to Bristol Children's hospital over several years, he developed some close relationships with its staff. One of the closest was with Katie, a brilliant play therapist who, when Torin was 11, asked me if she could apply to a charity that could send a family like ours on an all-expenses-paid trip of a lifetime together. She said: Ask him where he would go if he could go anywhere in the world." Continue reading...
‘It’s the perfect place’: London Underground hosts tests for ‘quantum compass’ that could replace GPS

Maya twins myth may have influenced child sacrifices, study suggests
DNA testing on 64 skeletons shows related boys were probably chosen as offerings in ancient city of Chichen ItzaGenetic analysis of the skeletons of 64 infant boys who are thought to have been sacrificed in the ancient Maya city of Chichen Itza more than a thousand years ago may shed light on the symbolic role twins played in the myths and rituals of their civilisation.In 1967, the remains of more than 100 children were found in a repurposed chultun, or underground cistern, near the sacred sinkhole at the ceremonial centre of the pre-Columbian city, which was one of the largest and most influential Maya settlements between AD600 and 1000.

Freud’s Last Session review – what-if meeting of minds with Anthony Hopkins as the master analyst
Hopkins' Sigmund Freud locks horns with Matthew Goode's CS Lewis in an imaginary encounter that is watchable but not terribly profoundHere is a determinedly old-fashioned drama, verbose and elaborate but also forthright and watchable in its way. It is a Stoppardian what-if meeting, imagining a bruising encounter between two celebrated historical figures who could, theoretically, have run into each other; it is adapted by director Matt Brown from a stage-play by American dramatist Mark St Germain, in turn inspired by a 2002 book by Harvard psychiatrist Armand Nicholi who had seized upon a report that Sigmund Freud met with an unnamed Oxford don just before his death. What if that don was CS Lewis, the Christian apologist who in his 1933 book The Pilgrim's Regress had mocked atheist Freudianism and every other sort of godless trendiness?Anthony Hopkins plays Freud at the very end of his life in exile in London in 1939 as war breaks out, in agony from mouth cancer. Matthew Goode is Lewis (also once famously played by Hopkins himself, of course, in the film Shadowlands), for whom fame through the wartime broadcasts and Narnia bestsellers was still in the future. Hopkins' Freud is querulous, cantankerous and bad-tempered; Goode's Lewis is diffident and supercilious. Lewis says Freud's worldview is morally evasive; Freud smirkingly suggests that Lewis's emotional relationship with the mother of his fallen first world war comrade is classic neurosis.

Why do women outlive men? Cells that develop into sperm and eggs could give the answer
Japanese scientists find blocking production in killifish of germ cells closes lifespan gap between males and femalesThe enduring mystery of why women outlive men may come down to the smallest and the largest cells in the body: the sperm and eggs that are central to human reproduction.Scientists in Japan have shown for the first time in vertebrates that cells that develop into eggs in females and sperm in males drive sex differences in lifespan, and that removing the cells leads to animals with the same life expectancy.

‘We’ve talked for hundreds of hours’: the joy of volunteering as a telephone friend
We're 50 years apart and have never met, but my connection with Pauline is deeper than I could have imaginedAll best friends were strangers once. Why, then, does reaching out to someone you don't know, making platonic connections in the modern world, feel like such a bold, even brave thing to do?Let me tell you about my friend, Pauline. Like all good friends, we make a point of catching up at least once a week, talking for hours about everything and nothing at all. But Pauline and I, while always there for each other, are unlike more conventional companions because, as well as being born 50-odd years apart, and living several hundred miles from each other, we've never actually met.

William Anders obituary
American astronaut who took the celebrated 1968 Earthrise photograph during the Apollo 8 mission to orbit the moonIt may be that the most famous picture from the US space programme is not the shot of Neil Armstrong landing on the moon, but the image of Earth, seen rising above the moon's horizon, an image relayed from space on 24 December 1968 by the crew of Apollo 8 - Frank Borman, Jim Lovell and Bill Anders.It was Anders, who has died aged 90, who snapped the Earthrise" photograph, which was not part of the mission's scheduled protocol. And it was he who read first from the Book of Genesis during their live transmission from lunar orbit that Christmas Eve. Continue reading...
‘The only limit is our imagination’: Tim Peake on what living in space taught him about life on Earth
Nine years after his first trip to outer space, Tim Peake is ready to blast off once again. He talks about preparing for the first all-British space mission - and setting his sights on MarsThe astronaut Tim Peake is tracking his cab driver on his phone. The car that will deliver him from our meeting to his next appointment (on a day packed with radio commitments) is late and Peake is calculating the most time-efficient route for us to meander through Soho's traffic, on foot, to reach it. Peake is the seventh UK-born astronaut in space and the first Briton to spacewalk - an unfathomable feat for us, but not for him. Space, he agrees, casting a glance at a printout of the schedule he keeps in his jacket pocket, might be easier to navigate than rush hour on Earth.We have already been chatting for an hour, in a snug above his agent's office. He announced his retirement as a European Space Agency (ESA) astronaut in January 2023, but we're meeting in the wake of news that he is preparing for a return to orbit on the first ever all-British space mission. That mission is due to launch next year and Peake is expected to be announced as the flight's commander within the coming weeks. The radio interviews he's conducting today coincide with a deadline for British businesses to make a case for their science to be included onboard, to be tested in microgravity as a priority for the mission: a strident bid to showcase Britain's Stem capabilities on an outer-world stage.

‘We’re trying to find the shape of space’: scientists wonder if the universe is like a doughnut
Rather than stretching to infinity and beyond, the universe may have a topology that can eventually be mappedWe may be living in a doughnut. It sounds like Homer Simpson's fever dream, but that could be the shape of the entire universe - to be exact, a hyperdimensional doughnut that mathematicians call a 3-torus.This is just one of the many possibilities for the topology of the cosmos. We're trying to find the shape of space," says Yashar Akrami of the Institute for Theoretical Physics in Madrid, a member of an international partnership called Compact (Collaboration for Observations, Models and Predictions of Anomalies and Cosmic Topology). In May, the Compact team explained that the question of the shape of the universe remains wide open and surveyed the future prospects for pinning it down. Continue reading...
