For decades physicists have been puzzling over the enigma of dark matter. We think it makes up 85% of the matter in the universe, but the mysterious substance cannot be seen or detected, and we know about it mainly through observations of the gravitational effects it has on other things. But now scientists believe they may be a step closer to detecting it. Science editor Ian Sample explains to Ma

Analysis of two skeletons reveals tooth wear and traces of psychoactive substance in what may be earliest known evidence for human drug taking What may be the earliest known evidence for human drug taking has been traced to ancient Indonesian foragers who sucked on mind-altering nuts as long as 25,000 years ago. Analysis of two exceptionally rare skeletons from the Indonesian island of Sulawesi r

CEOs may like to get up at the crack of dawn and go for a run, but I prefer optimising my life with lie-ins, trashy films, swearing and coffee This evening I’m going to tuck my five-year-old into bed and read her a chapter from one of her princess books, followed by a summary of research recently presented at the annual congress of the European Society of Cardiology. Once upon a time, I’ll tell h

Research finds temperature and amount of hot drinks consumed heightens possibility of developing disease Drinking very hot tea and coffee triples the risk of developing cancer of the gullet, the world’s largest study of the link between them has found. The findings show that people should let very hot cups of tea and coffee cool down until they are comfortable to drink, in order to reduce their r
Company behind ChatGPT says 10,000 of its AI systems cracked the Navier-Stokes problem in 88 hours OpenAI claims to have solved a major mathematics problem that has stumped humans for nearly a century after spending millions of dollars on the artificial intelligence-led endeavour. The company behind ChatGPT said it had cracked the Navier-Stokes problem, one of seven Millennium Prize Problems publ
Key regions of the brain linked to movement, learning and emotions were affected and may lead to cognitive problems Babies born to mothers with anaemia have smaller brains, particularly in key regions linked to movement, learning and the regulation of emotion, according to a study. Researchers said the differences, first detected at the age of one, could lead to cognitive problems when children s
Who’s more likely to steal sweets from a child? According to science, it’s the rich. A study seemingly confirming our suspicions about the moral behaviour of the wealthy was one of the winners of the 2026 Ig Nobel prizes, which honour research that makes you laugh and then think. Science editor Ian Sample tells Madeleine Finlay what the researchers think could be behind the phenomenon, and they e
Experts helped guide weather scenes in Pressure – a film depicting dramatic buildup to 1944’s D-day landings Dressed in a Royal Air Force uniform and sporting a trim moustache, Andrew Scott looks slightly queasy – as well he might. Behind him is a huge map of the Channel, and in front of him is Brendan Fraser, looming with a request: “I need a forecast,” he says. Starring in the film Pressure, ba
Scientists are battling over whether supposedly simple organisms should be considered ‘intelligent’. The outcome could reshape our understanding of the natural world – and our own place within it Forty years ago, as an undergraduate in Hokkaido, Toshiyuki Nakagaki came upon a lemon-yellow stain in a petri dish. That encounter turned him into a doyen of slime mould research – and fed a storm of bi

GLP-1 medications have been a gamechanger in the fight against obesity. But for a minority of patients, their impact is negligible. Why? When Mercedes was told by her doctor that she could be prescribed GLP-1 weight loss jabs in 2024, she broke down. “[When] she said yes, I cried in her office. And I didn’t really stop crying for a week,” she said. “Finally, after being overweight my entire life,

Volunteer ‘glow-getters’ overseeing reintroduction of endangered beetles at Nosterfield nature reserve The bioluminescent beams of “fairy folk” are shining again from a nature reserve in North Yorkshire for the first time in a century after the successful reintroduction of endangered glowworms. Female glowworms were spotted over multiple weeks at Nosterfield nature reserve this summer following a

From the Guardian Investigates team: Across the world, hundreds of people have come to believe they have made extraordinary scientific discoveries with AI chatbots such as ChatGPT, Claude and Gemini. Others say their AI has ‘awakened’ or is leading them to a higher spiritual realm. The Guardian journalist Michael Safi begins investigating a phenomenon labelled ‘AI psychosis’, travelling to the US
The moon will pass less than a degree north of the giant planet and will be on its other side the next morning Those already out and about at 5am this week will be rewarded with a beautiful waning crescent moon approaching Jupiter, while Mars watches on from a little further away.

A biography of the physicist recognises his achievements, but also reveals the selfish narcissist underneath When I wrote an unadoring review of Stephen Hawking’s final book, a collection of essays published posthumously in 2018, New Scientist suppressed some of my criticisms on the grounds that it was “too early” to voice anything other than praise for the physicist who died, aged 76, that March
