A complex ecosystem of woolly mammoths, bison, horses and big cats has been elucidated by studying the faeces of small rodents that probably ate the bigger animals
Bleaching has devastated reefs around the world, raising fears of an irreversible shift. Yet new interventions have revealed that corals can be remarkably resilient if we can give them enough help to recover
Drill cores at the impact site of the Chicxulub asteroid show evidence that, alongside widespread destruction, the collision created a vast underground ecosystem filled with hot water that sheltered microbial life
Brown dwarfs are somewhere between the size of a planet and a star, so how could we have potentially mistaken two of them for distant galaxies? Columnist Chanda Prescod-Weinstein argues that solving this cosmic mix-up is particularly possible now,...
Physics is considered a cold, hard science – but it will transform your life if you view it with a bit more subjectivity, says Karmela Padavic-Callaghan
Anthropic has warned that recursive-self-improving AI could be on the horizon, but the truth is the company is more immediately concerned with marketing itself for a blockbuster initial public offering on the stock market, says Matthew Sparkes
The out-of-Africa migration, in which ancient humans went on to inhabit every other continent except Antarctica, may not have been one moment in time, but a long and slow process. Columnist Michael Marshall examines how archaeologists are rethinking...
Lapses in memory are a normal part of ageing but can also be signs of dementia. Here’s how to distinguish between typical brain ageing and cognitive decline
A diverse range of bird species has been recorded at a solar park on rewetted peatland in Germany, suggesting that combining energy generation with habitat restoration could benefit biodiversity, the climate and the economy
UK Prime Minister Keir Starmer has warned tech firms, including Apple and Google, that they must voluntarily implement tools to stop children sharing explicit images, but experts warn this is easier said than done
Each decade the world is losing over 7 per cent of its freshwater storage capacity to sediment build-up, according to an analysis of over half a million reservoirs
One-third of people with anorexia nervosa don’t recover and treatment has remained stagnant for years. Now we’re beginning to understand how the condition takes over the mind
Endometriosis is usually thought of as a gynaecological condition, but a huge study shows it has links with cholesterol levels, inflammation and an altered microbiome
Mice seemed to reap some of the benefits of sleep by having their brain activity stimulated while they were awake, and the researchers plan to test the approach on people
A team in the US has reported promising results after using an improved form of CRISPR to gene-edit human embryos, but a major issue remains unsolved
Scientists warn that the Trump administration's push to dismantle a vital network of ocean-sensing instruments will stymie crucial weather and climate monitoring in the Pacific and Atlantic
The modern world depends on open-source software maintained by volunteers, but the added demands of checking and fixing AI-written submissions are causing some to burn out and quit
Mice that contain cells with an added rat chromosome have been created by scientists. The next step is to try this with frozen elephant tissue – and if that works, the team will try it with frozen mammoths
A seemingly simple set of rules kicks off a kind of mathematical magic trick, which has kept great minds busy since the 1930s. Columnist Jacob Aron explores the origins of the Collatz conjecture, why it is so addictive to mathematicians and whether...
Parents report loving their partners less within the first year of having a child, but that doesn't mean the feeling is permanent or inevitable
A patch of ocean south-east of Greenland is the only place on Earth that is cooling, and it could be a sign that the warm water "conveyor belt" in the Atlantic is slowing down
Rachel Carson’s look at the dire effects of industrial and agricultural pollution birthed the modern environmental movement when it was first published – and remains as crucial a read today, finds Rowan Hooper
A glacier could have carried the giant sandstone at the centre of Stonehenge southwards from north-east Scotland, but this scenario appears unlikely
Global warming will amplify the impacts of El Niño events, and could also make them much stronger and more far-reaching
Actor Ben McKenzie explores the world of crypto in an entertaining documentary that doesn't shy away from calling out those who have promoted the currency
A new retrospective of M.C. Escher’s work opens this week. Explore some of his most mind-bending, mathematically inspired works here
Despite AI's dizzying improvements in mathematical ability, its successes show just how integral human mathematicians are to the scientific process
Giulia Enders made her name with Gut, an exploration of our intestines. Now, in the compelling follow-up Organ Speak, she’s listening to what our other organs are telling us
Why do we have big brains? Or walk on two legs? Biological anthropologist and broadcaster Alice Roberts talks human exceptionalism, evolution and her new book Humans with Michael Marshall
A circle running along the 27° east and 153° west meridians divides the globe into two halves with equal reflectivity – and this may have implications for solar geoengineering schemes
A UN report warns of the rapid growth in AI energy consumption, but suggests users can improve efficiency by making prompts more concise
A quantum computer made from extremely cold atoms can correct its own errors during long computations, an important prerequisite for becoming truly useful
Restricting carbohydrates may sound like an unlikely approach to treating anorexia, but following a ketogenic diet was linked to recovery in nearly 75 per cent of people with the eating disorder in a small trial
Researchers studying a 5300-year-old mummified man have identified bacteria that lived in his gut when he was alive, as well as cold-tolerant fungi that colonised his body after death
Ages 40 to 65 see a period of turmoil in the brain that has previously been overlooked. But identifying problems during this time can protect your cognitive health for decades to come
