Decoded genome of meat in pup's stomach helps scientists build picture of what caused extinction of speciesResearchers have shed light on the final centuries of the woolly rhinoceros after studying a hairy lump of meat from the stomach of an ancient wolf cub that became mummified in the Siberian permafrost.The beautifully preserved remains of a two-month-old female wolf cub were discovered in 2011 near the village of Tumat in northeastern Siberia. The animal is thought to have died 14,400 years ago when a landslide collapsed its den, trapping the cub and others inside. Continue reading...

Society should only eject fellows for fraud or other defects in their research, says Paul NurseThe president of the Royal Society has reignited a row over Elon Musk's association with the body by arguing that fellows should only be ejected for fraud or other defects in their research.In an interview with the Guardian, Paul Nurse defended the academy's decision not to take action against Musk - who was elected a fellow in 2018 - despite claims the tech billionaire had violated its code of conduct, including by his role in slashing US research funding as part of the US department of government efficiency".

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."

Ynys Mon (Anglesey): The wolf moon is spectacular enough, but look east and you'll see a celestial titan the size of a pinprickAs unmissable as new year's fireworks, the wolf moon held theheavens for the first few nights of January, casting an unearthly radiance over everything, night almost as bright as day. Now, as that moon wanes, prepare to be wowed by a true planetary A-lister: Jupiter.Named after the king of the sky gods in Roman mythology, Jupiter rises each evening in the east, unmatched by any star save Sirius. Tonight, however, it will be at its biggest and brightest, having reached opposition", meaning we on Earth are directly between Jupiter and the sun. If you have never tried star" gazing before, tonight's the night to start. Continue reading...

Scientists at UCL say drug developers should focus on two risk-raising variants of the Apoe geneNew therapies for Alzheimer's disease should target a particular gene linked to the condition, according to researchers who said most cases would never arise if its harmful effects were neutralised.The call to action follows the arrival of the first wave of drugs that aim to treat Alzheimer's patients by removing toxic proteins from the brain. While the drugs slow the disease down, the benefits are minor, and they have been rejected for widespread use by the UK's National Institute for Health and Care Excellence (Nice).

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...

Reflecting a small fraction of incoming sunlight to reduce global heating is not a new idea. It is time to safely experimentThe world is warming fast - and our options to avoid catastrophic harm are narrowing. 2024 was the first full year more than 1.5C hotter than the 19th-century average. Emissions are still rising, with fossil fuel use expected to hit a new high in 2025. Permanent carbon removal technologies - often cited as a fix - are removing just tens of thousands of tonnes annually, almost nothing relative to the 5-10bn tonnes needed. Cutting emissions and scaling carbon removal remain essential. But they may not be enough.As suffering grows and ecosystems unravel, more people will ask: is there anything we can do to prevent these harms? The idea of reflecting a small fraction of incoming sunlight to reduce warming is not a new idea. In 1965, Lyndon B Johnson's science advisers proposed it as the only way to cool the planet. Earth already reflects about 30% of incoming sunlight; raising that fraction slightly - say, to 31% - could strengthen the planet's natural heat shield. But how? Continue reading...

There's nothing more uplifting than hearing about a world-shaking, life-enhancing new development. But science shouldn't overlook the small stuff, or stop looking for new species of cute, fluffy mammals ...People who greet the new year with hope, ambitious plans and optimised gut microbiomes might be obnoxiously apparent at the moment, but we all know they're a minority. Most of us lurched into 2026 catastrophically depleted and grey-faced, juggling deep Lemsip dependency with a deeper overdraft and a sense of ever-deepening global geopolitical foreboding. There is, however, one thing that fills me with buoyant optimism now and always: science. I don't understand it, but I'm delighted it's out there, making things better.I was booted out of my leaden year-end listlessness by The Atlantic's list of 55 Facts That Blew Our Minds in 2025. Did you know, for example, that scientists at UC Berkeley created a new colour? (It's called olo" and it's sort of teal.) Or that doctors treated a baby with a rare genetic disorder with custom gene editing? There were more wonders in the Smithsonian's list of last year's fascinating scientific discoveries: ichthyosaurs, extinct marine reptiles, had stealth flippers", snails can regrow eyes within a month, and flamingos form tornado-like vortices as they probe for prey", which is pure poetry (it looks pretty cool too, I watched one do it on YouTube). Still on an animal theme, entomologists discovered a bone collector" caterpillar that conceals itself in the body parts of its prey (I'm sure he's lovely when you get to know him). 2025 was also the year science made oyster mushrooms play keyboards (sort of), astronomers discovered more than 100 moons in our solar system and medical researchers created replica womb lining and made astonishing progress towards lab-grown teeth.

Solar system's biggest planet will be close enough to reveal its largest moons through a pair of modest binocularsThe giant planet Jupiter reaches its closest approach to the Earth in 2026 this week. It is extremely well placed for observation and so bright that it is impossible to miss.Jupiter - the largest planet in the solar system - will be unmistakable in Gemini, the twins, forming a lopsided triangle with the constellation's two brightest stars, Castor and Pollux. Its diameter is more than 11 times that of the Earth, and its cloud decks are highly reflective, making it the brightest planet in the night sky apart from Venus, despite it being so much further away. It will be visible from northern and southern hemispheres. Continue reading...

Three decades after its modest beginnings on Channel 4, the TV juggernaut now has its own channel and global subscribersThirty-two years ago, a small group of archaeologists gathered for a weekend in Somerset to make a TV programme about a field in Athelney, the site where once, 1,200 years ago, King Alfred the Great rallied resistance to the invading Viking army.There weren't many concessions to showbiz glitz. Instead, a group of blokes with unruly hair and a couple of women walked across a field, talked things over in the pub and, at one point, gathered around a dot matrix printer to watch it slowly disgorging some results. The most exciting artefact they found was a lump of iron slag. No soil was overturned. Continue reading...

Scientists argue ape-like Sahelanthropus tchadensis that lived in Africa 7m years ago is best contender but more fossils are neededIn the murky first chapters of the human story is an unknown ancestor that made the profound transition from walking on all fours to standing up tall, an act that came to define us.The odds of stumbling on the fossilised evidence of such an evolutionary prize are slim, but in new research, scientists argue that an ape-like animal that lived in Africa 7m years ago is the best contender yet.

Over the holiday period, the Guardian leader column is looking ahead at the themes of 2026. Today we examine how the White House's war on vaccines has left the future of a key technology uncertain and up for grabsThe late scientist and thinker Donald Braben argued that 20th-century breakthroughs arose from scientists being free to pursue bold ideas without pressure for quick results or rigid peer review. The rapid development of Covid-19 vaccines seemed to validate his claim: emergency conditions sped up trials, relaxed regulatory sequencing and encouragedscientists to share findings before peer review. Out of that sprang one of the great scientific success stories of our age: mRNA vaccines. These use synthetic genetic code to train the immune system to defend itself against viruses. Katalin Kariko and Drew Weissman, whose work enabled the mRNACovid vaccine, went on to win the Nobel prize. Theirbreakthrough suggests that loosening traditionalconstraints could accelerate major scientific advances.The extensive scientific and logistic infrastructure built during that period is now occupied with turning the technology towards other diseases: flu, HIV and even cancer. Until very recently, the US, which put more than $10bn into mRNA development, appeared primed to reap the scientific and commercial rewards. Despite the deregulatory zeal that birthed mRNA, the second Trump administration has rejected it. Instead, it has been remarkably steady in its commitment to the radical anti-science and anti-vaccine agenda of the US health secretary, Robert F Kennedy Jr. He has spent the past year undermining and outright sabotaging the US's own success. Over the summer, the US Department of Health and Human Services announced a coordinated wind-down" of federal funding for mRNA research, cancelling an additional $500m in funding for 22 projects.Do you have an opinion on the issues raised in this article?
