Astronomers may be closing in on a long-standing cosmic mystery: why some of the universe’s biggest galaxies seem to have far fewer stars than expected。 Using NASA- and JAXA-supported XRISM observations of a galaxy called NGC 4151, researchers found strong evidence that supermassive black holes can unleash powerful winds that blow away the raw mate
Plague was already a deadly killer 5,500 years ago, long before cities, farming, or the rat-infested conditions usually linked to historic outbreaks。 By analyzing ancient DNA from hunter-gatherer cemeteries in Siberia, researchers discovered early plague strains in nearly 40% of the individuals studied and found evidence of rapid family-based outbr
Parrots may be doing more than just repeating words—they may actually use names。 By analyzing hundreds of recordings from pet parrots, researchers found evidence that many birds use specific names to identify particular people, animals, and even individual companions。 Some parrots appeared to refer to someone who wasn’t present, while others used n
One of the most celebrated claims about Yellowstone’s wolves is facing a major challenge。 Scientists say the study behind the famous trophic cascade story relied on flawed methods that overstated the ecological impact of wolf recovery。 Their reanalysis found no evidence for a dramatic, park-wide surge in willow growth
A bold claim that the universe’s accelerating expansion was an illusion has been put to the test—and failed。 Researchers found that the study behind the controversy made key mistakes when analyzing supernova data。 After revisiting the evidence, astronomers concluded that cosmic acceleration remains as strong as ever
Scientists found that transfer learning can make the search for new physics in the universe much faster, slashing the need for expensive simulations。 Yet the approach can backfire when AI relies too heavily on familiar patterns, potentially missing evidence of something truly new
The private events group, cofounded by Peter Thiel, says a “criminal” hacker is behind a breach that exposed members’ personal details。 WIRED found no evidence a break-in was needed to access the files
A rare meteorite has revealed evidence of a massive lost world that once orbited the young Sun before being destroyed in a catastrophic collision。 The discovery suggests some early planets formed from dramatically different materials than Earth and Mars, rewriting part of the solar system’s origin story
Scientists have developed an artificial photosynthesis system that essentially regulates itself, eliminating the need for batteries used in many current designs。 The key innovation is an electrolyzer that automatically adapts to changing sunlight by altering its electrical properties as it heats up。 This keeps solar fuel production more stable whil
