Scientists have developed a solar-powered desalination system that turns seawater into fresh water while removing nearly all of the leftover salt as a solid instead of producing harmful brine. The self-cleaning technology could also recover valuable mi…

Scientists have discovered that some severe genetic disorders linked to rapid aging may be driven not just by damaged DNA, but by the body’s overreaction to that damage. When broken DNA fragments leak into the wrong part of a cell, an immune sensor cal…

A newly identified 240-million-year-old animal from Tanzania is forcing scientists to rethink the early dinosaur timeline. Dinodontosaurus isiyavamanda belongs to a group previously known only from South America, linking fossil deposits on the two cont…

Eating four to six servings of whole grains a day may deliver meaningful benefits for heart health, according to a large review of 87 clinical trials. Researchers found improvements in body weight, waist size, blood pressure, cholesterol, blood sugar, …

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 o…

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 unti…

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 int…

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 S…

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 result…

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 de…

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-carbohydra…
