A return to nuclear power is at the heart of Japan's energy policy but, in the wake of the 2011 disaster, residents' fears about tsunamis, earthquakes and evacuation plans remainThe activity around the Kashiwazaki-Kariwa nuclear power plant is reaching its peak: workers remove earth to expand the width of a main road, while lorries arrive at its heavily guarded entrance. A long perimeter fence is lined with countless coils of razor wire, and in a layby, a police patrol car monitors visitors to the beach - one of the few locations with a clear view of the reactors, framed by a snowy Mount Yoneyama.When all seven of its reactors are working, Kashiwazaki-Kariwa generates 8.2 gigawatts of electricity, enough to power millions of households. Occupying 4.2 sq km of land in Niigata prefecture on the Japan Sea coast, it is the biggest nuclear power plant in the world. Continue reading...

These microscopic mites, which burrow under your skin and cause ferocious itching, are incredibly hard to get rid of - and cases in the UK have soared. What is causing the outbreak, and is there anything we can do about it?Louise (not her real name) is listing the contents of a bin liner she has packed with fresh essentials in case of emergency. Clothes, toothbrushes, hairbrushes, a teddy ... Although it should be two teddies," she re-evaluates, quickly. I can hear her trying to quell her panic.A diehard survivalist preparing for catastrophe? Actually, a beleaguered 44-year-old mother recovering from scabies - an itchy rash caused by microscopic mites that burrow under human skin.

She is now on tenterhooks in case they return. Continue reading...

The food, beauty and pharmaceutical industries poison our self-image. GLP-1 drugs will only make them richer - and strengthen the hold they have over usFifty years ago, I started thinking about the demand for women to look a certain way and the rebellions against the narrow ways in which we were supposed to display (and not display) our bodies. For a while, there was a conversation about the strictures. Some young women refused to conform. Some women risked being in the bodies they had rather than embodying the dominant images of being Madonna or the whore. But troubled eating abounded, even if it wasn't always visible, stoked by the food and diet industries and their bedfellows in the beauty and fashion industries. These industries targeted appearance as crucial to girls' and women's identity and their place in the world.Today, a new kind of troubled eating is stalking the land, entirely induced by the new GLP-1 weight-loss drugs produced by pharmaceutical companies and promoted by their willing agents on social media. It is totally understandable that people want relief from obsessive and invasive thoughts about their bodies and food. The explosion of GLP-1 drugs has provided a kind of psychological peace for many who feel less frightened of their appetites.Susie Orbach is a psychotherapist, psychoanalyst and social critic. She is the author of many books, including Bodies and Fat Is a Feminist Issue Continue reading...

This is the moment a SpaceX capsule left the International Space Station on an emergency return flight to Earth prompted by a medical issue afflicting one of the astronauts. It is Nasa's first medical evacuation, with the mission being cut a month short. Onboard were American astronauts Mike Fincke and Zena Cardman, a Russian cosmonaut Oleg Platonov, and a Japanese astronaut Kimiya Yui. Computer modelling predicted a medical evacuation from the space station every three years but Nasa has not had one before in its 65 years of human spaceflight

Exclusive: Some scientists say many detections are most likely error, with one high-profile study called a joke'High-profile studies reporting the presence of microplastics throughout the human body have been thrown into doubt by scientists who say the discoveries are probably the result of contamination and false positives. One chemist called the concerns a bombshell".Studies claiming to have revealed micro and nanoplastics in the brain, testes, placentas, arteries and elsewhere were reported by media across the world, including the Guardian. There is no doubt that plastic pollution of the natural world is ubiquitous, and present in the food and drink we consume and the air we breathe. But the health damage potentially caused by microplastics and the chemicals they contain is unclear, and an explosion of research has taken off in this area in recent years. Continue reading...

It is the most essential thing we do - yet many of us arguably breathe badly. The author of Breath explains how that can be changedIn the last stages of writing his book, Breath, James Nestor was stressed. Which was ironic when writing a book about breathing patterns and mellowing out," he says. The book was late; he'd spent his advance and was haemorrhaging even more money on extra research that was taking him off in new, potentially interesting, directions - was it really necessary, he wondered, to go to Paris to look at old skulls buried in catacombs beneath the city? (It was.)Then a couple of months before the book's May 2020 publication date, the Covid pandemic hit, and Nestor was advised to wait it out. He couldn't afford to. One of the main motivations for releasing it at that time was to get that [on-publication] advance," he says. But I'll be honest, I didn't want to release it. I said: How are you going to promote a book that can't be sold in stores, that I can't tour for?'" He expected, he says, absolutely zero to happen". Continue reading...

Behaviour among non-human species could help keep groups together in face of social challenges, says studySame-sex sexual behaviour among non-human primates may arise as a way to reinforce bonds and keep societies together in the face of environmental or social challenges, researchers have suggested.Prof Vincent Savolainen, a co-author of the paper from Imperial College London, added that while the work focused on our living evolutionary cousins, early human species probably experienced similar challenges, raising the likelihood they, too, showed such behaviour.

Recorded in cave drawings as far back as 1000BC, this is one of the oldest zodiacal constellations to be recognised in its modern formTaurus, the bull, is our focus this week. One of the oldest constellations to be recognised in its modern form, it was recorded as the bull of heaven in Babylonian records from about 1000BC, but cave drawings from Lascaux, France, suggest that humans may already have associated the stars with a bull approximately 14,000 years earlier.Taurus sits on the ecliptic, the path that the Sun follows around the sky throughout the year, so it is known as a zodiacal constellation. The brightest star in the constellation is the red giant star Aldebaran. In Arabic, its name means eye of the bull". Continue reading...

Neuroscientist Ben Rein is on a mission to show that being around others not only feels good, but can even improve recovery from strokes, cancer and heart attacks. So why are so many of us isolated and glued to our phones?I hate it." I've asked the neuroscientist Ben Rein how he feels about the online sea of junk neuroscience we swim in - the dopamine fasts", serotonin boosts" and people regulating" their nervous system" - and this is his kneejerk response. He was up early with his newborn daughter at his home in Buffalo, New York, but he's fresh-faced and full of beans on a video call, swiftly qualifying that heartfelt statement. Let me clarify my position: I don't hate it when it's accurate, but it's rarely accurate."He draws my attention to a reel he saw recently on social media of a man explaining that reframing pain as neurofeedback, not punishment" activates the anterior cingulate cortex (a part of the brain involved in registering pain). That's genuinely never been studied; you are just making this up," he says. He posted a pithy response on Instagram, pleading with content creators to leave neuroscience out of it". That's why I think it's especially important for real scientists to be on the internet," he says. We need to show the public what it looks like to speak responsibly and accurately about science."

We must not let geoengineering be shaped behind closed doors. Climate justice demands an inclusive approachAs the world faces the challenges of the climate crisis and critical threshold levels or tipping points may be reached soon, a disputable idea is gaining momentum as a potential solution: solar geoengineering - the deliberate reflection of sunlight to cool the planet. Advocates argue it could buy us time. Critics warn of unknown risks. Some see it as a possible emergency break if temperatures spiral out of control. Others call it a dangerous distraction that undermines meaningful climate action.Research into solar geoengineering is advancing, including exploration of techniques such as stratospheric aerosol injection, which would involve spraying tiny reflective particles into the upper atmosphere to mimic the cooling effect of volcanic eruptions, and marine cloud brightening, which aims to enhance the reflectivity of low-lying marine clouds. While stratospheric aerosol injection is not being conducted, these technologies are being studied with increasing urgency in the global north. In the global south, however, they remain largely invisible to public discourse and policymaking. Continue reading...
