Scientists reconstructed videos from the brain activity of mice, producing 10-second clips based only on signals from neurons in the visual cortex. The breakthrough could help reveal how the brain reshapes what we see before it becomes our perception ...

Venus may have once had a moon, but new research suggests the planet's incredibly slow rotation could have doomed it. Computer simulations showed that instead of gradually drifting away like Earth's moon, a Venusian moon would likely spiral inward .. ...

U.S. irrigation produces some greenhouse gas emissions, but new research suggests it prevents vastly more by allowing farmers to grow more food on less land. Without irrigation, replacing lost crop yields could require converting natural ecosystems . ...

A new study suggests Earth formed almost entirely from material in the inner Solar System, challenging the idea that water-rich material from beyond Jupiter played a major role. If correct, Earth's water may have been present much closer to the young ...

The James Webb Space Telescope has revealed surprising changes in the rings around Chariklo, a small object orbiting between Saturn and Uranus. Over just a few years, its inner ring became more opaque while its outer ring became less opaque. The ...

Eating more ultra-processed foods was linked to greater fat buildup inside thigh muscles, according to MRI scans of 615 adults at risk for knee osteoarthritis. Surprisingly, the association remained even after researchers accounted for calorie intake ...

A naturally occurring molecule called erucamide may help the retina fight back against diseases that cause progressive vision loss. Restoring the molecule activated protective immune responses that helped stabilize retinal tissue and slow aspects of ...

Older adults who changed the balance of fat, carbohydrates, and animal protein in their diets showed signs of reduced biological age after just four weeks. The strongest result appeared in participants eating an omnivorous, lower-fat, higher ...

The Hunga Tonga eruption may have triggered a surprising chemical reaction that destroyed some of the methane released into the atmosphere. Scientists say the discovery could reshape estimates of methane pollution and inspire new methods for slowing ...

Simply smelling chocolate helped men complete more leg extension repetitions without making the workout feel harder, with dark chocolate producing the strongest effect. The researchers think familiar food aromas may influence appetite and motivation ...
