A study led by Jenny Frediani at Stockholm University has revealed a planet-forming disk with a strikingly unusual chemical composition: an unexpectedly high abundance of carbon dioxide (CO2) in regions where Earth-like planets may one day form. The discovery, made using the James Webb Space Telescope (JWST), challenges long-standing assumptions about the chemistry of planetary…
In a new study, scientists at the University of Missouri looked deep into the universe and found something unexpected. Using infrared images taken from NASA’s powerful James Webb Space Telescope (JWST), they identified 300 objects that were brighter than they should be. “These mysterious objects are candidate galaxies in the early universe, meaning they could…
Conservative leader Kemi Badenoch has said her party will remove all net zero requirements on oil and gas companies drilling in the North Sea if elected. Badenoch is to formally announce the plan to focus solely on “maximising extraction” and to get “all our oil and gas out of the North Sea” in a speech…
Esme Stallard and Justin RowlattClimate and science team Sean Gallup/Getty Images It is smaller than your fingernail, but this hairy beetle is one of the biggest single threats to the UK’s forests. The bark beetle has been the scourge of Europe, killing millions of spruce trees, yet the government thought it could halt its spread…
Stethoscopes powered by artificial intelligence (AI) could help detect three different heart conditions in seconds, researchers say. The original stethoscope, invented in 1816, allows doctors to listen to the internal sounds of a patient’s body. But now a British team have designed one that can spot heart failure, heart valve disease and abnormal heart rhythms…
When genetic testing reveals a rare DNA mutation, doctors and patients are frequently left in the dark about what it actually means. Now, researchers at the Icahn School of Medicine at Mount Sinai have developed a powerful new way to determine whether a patient with a mutation is likely to actually develop disease, a concept…
A team of computer scientists led by the University of Colorado Boulder has developed a new artificial intelligence platform that automatically seeks out “questionable” scientific journals. The study, published Aug. 27 in the journal “Science Advances,” tackles an alarming trend in the world of research. Daniel Acuña, lead author of the study and associate professor…
The world’s most unusual dinosaur is even stranger than first realized… Research published in Nature on August 27 reports that Spicomellus afer had a tail weapon more than 30 million years before any other ankylosaur, as well as a unique bony collar ringed with meter-long spikes sticking out from either side of its neck. Spicomellus…
For the first time, researchers have uncovered direct genomic evidence of the bacterium behind the Plague of Justinian — the world’s first recorded pandemic — in the Eastern Mediterranean, where the outbreak was first described nearly 1,500 years ago. The landmark discovery, led by an interdisciplinary team at the University of South Florida and Florida…
Over the past 50 years, rates of obesity and type-2 diabetes have soared, while sperm quality has plummeted. Driving these changes could be the increasing popularity of ultra-processed foods, which have been linked to a range of poor health outcomes. However, scientists still aren’t sure whether it’s the industrial nature of the ingredients themselves, the…
