NASA’s Artemis I mission reveals surprising radiation levels near the Moon

NASA’s Artemis I mission has provided new insights into how much cosmic radiation astronauts may encounter near the Moon compared with low Earth orbit. Using experimental detectors made from lithium fluoride crystals aboard the Orion spacecraft, researchers have obtained preliminary measurements that reveal unexpected differences in radiation exposure between the…

Antarctica’s “Doomsday Glacier” could raise sea levels twice as much as predicted

A new computer model suggests that Antarctica’s Thwaites Glacier, often called the “Doomsday Glacier,” could contribute far more to rising sea levels than scientists previously estimated. Developed by researchers at the University of California, Irvine, and NASA’s Jet Propulsion Laboratory, the model predicts that melting from the massive West Antarctic…

A simple daily fiber supplement reduced arthritis pain and improved strength

A simple daily fiber supplement may offer a surprising new way to relieve knee arthritis pain while improving muscle strength. In a clinical trial led by researchers at the University of Nottingham, people with knee osteoarthritis (OA) who took a prebiotic fiber called inulin experienced significant reductions in pain, improved…

The autistic brain processes faces differently than scientists thought

A major new study has uncovered important differences in how the brains of autistic children respond to human faces. Published in Nature Mental Health, the research is among the most extensive investigations yet into how face perception works in autism. Some autistic people tend to look at faces less frequently…

The asteroid that killed the dinosaurs may have helped ants conquer the world

Around 66 million years ago, an asteroid struck Earth and brought the age of the dinosaurs to an end. The mass extinction that followed created opportunities for countless other animals to evolve and spread. Ants were among the groups that eventually became remarkably successful, and scientists have now identified a…

Scientists discover the immune system’s hidden sense of touch

Scientists at McGill University have discovered a surprising ability in immune cells that could reshape our understanding of how the body develops lasting protection against infections.
