Hackers got nearly 7 million people’s data from 23andMe. The firm blamed users in ‘very dumb’ move
The company pointed at people who failed to update their passwords' as sensitive data was offered for sale on forumsThree years ago, a man in Florida named JL decided, on a whim, to send a tube of his spit to the genetic testing site 23andMe in exchange for an ancestry report. JL, like millions of other 23andMe participants before him, says he was often asked about his ethnicity and craved a deeper insight into his identity. He said he was surprised by the diversity of his test results, which showed he had some Ashkenazi Jewish heritage.JL said he didn't think much about the results until he learned of a huge breach at the company that exposed the data of nearly 7 million people, about half of the company's customers. Worse, he later learned of a hacker going by the pseudonym Golem" who had offered to sell the names, addresses and genetic heritage reportedly belonging to 1 million 23andMe customers with similar Ashkenazi Jewish heritage on a shadowy dark web forum. Suddenly, JL worried his own flippant decision to catalog his genes could put him and his family at risk. Continue reading...

Genetics may help explain Black men’s high prostate cancer risk, say scientists
Exclusive: Researchers find mutations that are more common in men with African ancestry after DNA analysisScientists have discovered genetic mutations that could help explain why Black men are at higher risk of developing prostate cancer than those of other ethnicities. The findings could lead to a test to identify those at greatest risk of developing the disease, enhancing survival rates.Prostate cancer is the most common cancer among British men, with about 52,300 new cases and 12,000 deaths recorded in the UK each year. Black men are twice as likely to be diagnosed and 2.5 times more likely to die from the disease compared with white men. Continue reading...

Adam Sillito obituary
Visual neuroscientist who transformed the Institute of Ophthalmology in London into a world-class centre of excellenceAdam Sillito, emeritus professor of visual science at the Institute of Ophthalmology in London, who has died aged 79, described one of his recreations in Who's Who as dreaming of better things". A lateral thinker who grasped the bigger picture, he carried out research into the mechanics of visual perception that yielded vital knowledge for future treatments. As director of the institute from 1991 until 2006, he transformed it from a backwater on the verge of closure to a world-class centre of excellence, partnering with Moorfields eye hospital and attracting top scientists from all over the world.In the 1970s, Sillito was a lecturer at the University of Birmingham and exploring an aspect of the intricate process of visual perception. In order to see", neurons must relay information from the eyes to the visual cortex in the brain, where it is interpreted as images. At the time researchers were mostly interested in how neurotransmitters have an excitatory" effect on neurons, causing them to fire and transmit information to the next cell. Continue reading...

Young great apes tease and annoy their elders in playful behaviour – video
Footage of great apes has revealed that humans are not the only ones to endure seemingly endless bouts of teasing dished out by their young ones who appear intent on pushing their luck.Recordings of chimps, orangutans, bonobos and gorillas found the animals to be masters of the dubious art, embarking on an impressive range of playful and occasionally somewhat aggressive acts ranging from the cheeky and plain silly to the fabulously irritating.From 75 hours of footage taken at San Diego and Leipzig zoos, scientists documented 142 clear instances of great apes teasing their compadres, with most instigated by juveniles aged three to five years old
True romance: how to keep the love alive when your partner has been unfaithful
Being cheated on feels like the end of the world. It takes hard work, but relationships can surviveThe trouble with romantic betrayal - apart from the obvious pain - is that it is the salacious lifeblood of everything from tabloid headlines and box sets to true crime podcasts. Because of this, there is a tendency to view it in highly dramatic terms. That is fine when we are snuggled up on the sofa watching other people's heartbreak at a distance, but less helpful when it arrives closer to home.He's a cheater," gossiped one friend recently about a mutual acquaintance's partner. She needs to throw him out and change the locks." Well, maybe. But the man in question is a mild-mannered accountant who had, in the space of six months, lost his mother and his job. Could this have been a temporary blip? Continue reading...

The Space Shuttle That Fell to Earth review – the finest possible tribute to the astronauts who lost their lives
This moving, thorough analysis of what went wrong when seven Nasa crew members died 20 years ago doesn't waste a moment. It's a full, fitting memorial that's not a minute too longThe three-part documentary The Space Shuttle That Fell to Earth marks the 20th anniversary of the Columbia disaster, when one of the most complex machines ever built by the human race" disintegrated on the return journey of its 28th mission, killing all seven astronauts on board.It is a commemoration, in the fullest sense, of the men and women who died. Contemporary footage of press interviews, tapes made during their training and recordings created while they carried out their 16-day mission in space (including chats to their families back on Earth) show them as living, breathing human beings, almost until the very moment that the shuttle failed. They are interwoven with current-day interviews of surviving members of their families, notably commander Richard Husband's wife, Evelyn, mission specialist Michael P Anderson's wife, Sandy, and daughter, Kaycee, payload specialist Ilan Ramon's son, Tal, and mission specialist Laurel Clark's husband, Jon, and son, Iain. The other astronauts who lost their lives were pilot William C McCool and mission specialists Kalpana Chawla and David M Brown. Everyone remembering them is thoughtful, articulate, gentle and clearly shaped by the losses they have been carrying for 20 years.The Space Shuttle That Fell to Earth aired on BBC Two and is available on BBC iPlayer.

Atmospheric river storms are getting stronger, and deadlier. The race to understand them is on
As the climate crisis supercharges storms over the Pacific, scientists are creating tools that can measure them from the insideThe storm raged over California for more than five days. As the powerful atmospheric river made landfall, furious winds and torrential downpours ripped trees from their roots, turned streets into rivers and sent mud cascading into homes.Along with chaos, the storm brought opportunity. Scientists were ready, on land and in-flight, to deploy instruments that measure atmospheric rivers like this one. They released tools from planes, equipped with small parachutes, or floated them up from the ground attached to balloons, directly into the storm's path. Continue reading...

I felt lost in early adulthood, so coined the term ‘quarterlife’ as a focus for study
Adrift after leaving university, Satya Doyle Byock turned to psychology to bridge the journey to adulthoodWhen Satya Doyle Byock finished her studies after nearly 20 years, she felt like she was stepping off a cliff. Adulthood seemed perilously unclear. I was in my 20s and in crisis, looking around myself at friends in crisis," says Byock, now 40. Only a few of her fellow graduates seemed clear-eyed about the future, with jobs or further study lined up. The rest had absolutely no idea".After graduating, Byock volunteered abroad, at a prison in Colombia, in tsunami relief in Sri Lanka, before landing a job as a project manager at a software startup in Portland. It was a good job", in a buzzy sector, with a decent salary. But Byock's disorientation persisted. In her journals she wondered if she was on the right path and why she didn't feel satisfied.

‘Cosmic time machines’: how space telescopes transformed our ability to understand the universe
The launch of Hubble in 1990 marked a turning point in our quest to unravel the mysteries of deep spaceIf you've ever been blown away by an image of outer space, it's a pretty safe bet it was taken by a spacecraft. That's no surprise if we're talking about the planets of our own solar system, where probes have been sending back spectacular closeups since the 1960s. But what about all those nebulae, star clusters and galaxies that are much farther away? For stunning astrophotography, nothing can beat Nasa's Hubble space telescope, or its huge new successor, the James Webb space telescope (JWST). They're called space telescopes not just because they observe space, but because they're located in space.The JWST, for example, is about 930,000 miles (1.5m kilometres) away - approximately four times as far as the moon and far enough that radio signals sent from Earth, travelling at the speed of light, take about five seconds to reach it. In other words, the JWST is about five light seconds away from Earth. But many of the galaxies it has photographed are hundreds of millions, or even billions, of light years away. Clearly, the reason for locating the JWST, and Hubble before it, in space has nothing to do with getting closeup pictures. They're no nearer to the objects they're viewing than telescopes here on Earth. So why do astronomers go to all the trouble and expense of putting telescopes in space? Continue reading...
Breaking Through: My Life in Science by Katalin Karikó review – real-life lessons in chemistry
This vivid account of the Hungarian biochemist who endured decades of derision before pioneering Pfizer's Covid vaccine is a tribute to her tenacity and self-beliefIn May 2013, Katalin Kariko turned up for work at her laboratory at the University of Pennsylvania and found her belongings piled in the hallway. There were my binders, my posters, my boxes of test tubes," she recalls. Nearby a lab technician was shoving things into a trash bin. My things!" Kariko realised.Despite having worked at the tiny lab for years, the scientist - then in her 50s - was cast out, without notice, for failing to bring in sufficient dollars per net square footage". In short, she had not attracted enough grants to justify the meagre space she occupied. Continue reading...
Power tools at the ready! The life-changing science behind hip and knee replacements
Thousands of people are given new joints each year in the UK. But can robots and smart tech soon make it a smoother procedure?Ian Doncaster is remarkably chipper for a man about to undergo major surgery. I have a busy life. So it's nice to have a break," he jokes. It is 8.30am on a chilly December morning and here at Warwick hospital he is about to receive a new knee - or part of one.At 62, Doncaster has always been active: he played rugby when young, until a knee injury and subsequent operation meant he had to trade that in for a host of other sports. But now the knee is causing problems again. As a self-employed chartered engineer, he needs to be able to get up and down tower blocks. Even going hiking with his wife seems a wistful dream. Going forward, it's only going to get worse," he says. Continue reading...

Asthma of the oesophagus: the alarming rise of a rare inflammatory condition
The little-known digestive disease is hard to diagnose but can affect swallowing and require emergency treatmentLisa Thornton was heavily pregnant and in her early 30s when she noticed the feeling of a blockage in her oesophagus, the muscular food pipe that connects the mouth to the stomach. At the time, I just thought it was just the pregnancy," says Thornton, now 50, who lives in the New Forest in Hampshire. I thought it was everything pushing up. But a few years later, things started to get worse."During a Sunday roast with her family, a chunk of broccoli suddenly lodged in her throat, causing spasms that persisted for hours. Any attempts to wash it down with water failed as the fluid simply came straight back up. Thornton drove to a nearby drop-in centre, where doctors tried, without success, to free the blockage with muscle relaxants. Continue reading...

‘The self is suppressed’: psychologists explore the minds of the mafiosi
Italian researchers say that joining the mafia is like entering a cult in which members must leave behind their own identityLeonardo Vitale made his way into the Sicilian mafia at age 19 by killing a boss from a rival clan. He continued his violent career as a mafioso for the next 12 years until his arrest in 1972 and transfer to a maximum-security prison when, after a week of isolation, he began to self-harm and show signs of depression.Overwhelmed by remorse for the criminal acts he had committed, Vitale suffered a nervous breakdown. The former boss felt guilty" and impure" to the point that, upon his release from prison a year later, he voluntarily went to the police station in Palermo to confess to two murders. He also provided the names of dozens of other bosses involved in criminal activities. Diagnosed with diminished capacity and schizophrenia by doctors, he was placed in a psychiatric hospital. When he was released, the mafia had already condemned him to death. Vitale was killed with two gunshots to the head on 2 December 1984. Continue reading...

Do I really look like Ukraine’s top general? I have a much nicer forehead | Adrian Chiles
Valerii Zaluzhnyi and I both have deeply furrowed brows. Should one or both of us be thinking about Botox?About 15 years ago, an Australian woman I worked with took me to one side and told me I should get Botox. I was busy building a career as a television presenter and she felt very strongly that, if I wasn't careful, something would hold me back. It's that frown line across the middle of your forehead. It's kind of distracting," she said. It'll only get worse," she added. Her tone was neither kind nor unkind. No particular offence was taken.She was right about one thing: it has got worse. I was barely in my 40s then. The line has since deepened, into first a crevice and then a canyon. Around the time of my 50th birthday, the tops of the canyon sides closed up, turning it into a kind of tunnel, I suppose you'd have to call it. No daylight gets in there unless I physically pull my forehead back. Or I'm very astonished by something. These days - I'm 57 next month - it's so deep that to clean it properly I need to use a small toothbrush. You'd be amazed what turns up in there.Adrian Chiles is a broadcaster, writer and Guardian columnistDo you have an opinion on the issues raised in this article?

Fungi: Web of Life review – Björk and Merlin Sheldrake guide trippy mushroom doc
Beginner's guide to the wrap-your-brain-around-them facts of mycological science boosts the wonder with 3D time-lapse photographyIf you've got face of fungi" biologist Merlin Sheldrake's global bestseller Entangled Life on your bookshelf, unbattered and spine uncracked, this documentary might feel like an easier option. A beginner's guide to fungi, just 40 minutes long, it is narrated by Bjork and presented by the gently eccentric Sheldrake (imagine Timothee Chalamet playing a Cambridge academic, with a mop of unruly curls). It's being released in 3D on the giant screen at London's BFI Imax - all the better to gawp at Steve Axford's trippy time-lapse photography of strange, wondrous and beautiful fungi.Like Sheldrake's book, the film is on a mission to change the way we look at fungi - and the world. Fungi made life possible on Earth, and virtually all trees - and 90% of plants - rely on fungus to survive. The vast underground networks of fungi that provide trees with nutrients - the wood wide web" - are dazzlingly visualised here. Fungus is a miracle worker too: giving us life-saving medicines and decomposing organic matter. (Without fungi, forests would be tree-deep in animal carcasses.) Continue reading...
Weatherwatch: How rain erodes high-speed aircraft
Aerospace industry has researched extensively into how raindrops affect planes and spacecraft travelling at high velocityRain blown by the wind batters your face. Driving on a motorway, it smashes into your car windscreen with even greater force. At high speeds raindrops can wear away solid materials, which is a serious concern in the aerospace industry.For propeller aircraft, rain was mainly a vision problem, but in the jet age planes were vulnerable to raindrops eroding paint coatings and damaging plastic, ceramic and even metal components. The problem was even more acute with rockets; to a spacecraft re-entering the atmosphere at high velocity, every droplet is a liquid bullet. Continue reading...
