NASA's Suni Williams—one of two astronauts stuck for months at the International Space Station—has retired.
Solar Orbiter has captured the clearest evidence yet that a solar flare grows through a cascading “magnetic avalanche.” Small, weak magnetic disturbances rapidly multiplied, triggering stronger and stronger explosions that accelerated particles to extreme speeds. The process
A new building material developed by engineers at Worcester Polytechnic Institute could change how the world builds. Made using an enzyme that turns carbon dioxide into solid minerals, the material cures in hours and locks away carbon instead of releasing it. It’s strong,
Just as avalanches on snowy mountains start with the movement of a small quantity of snow, the ESA-led Solar Orbiter spacecraft has discovered that a solar flare is triggered by initially weak disturbances that quickly become more violent. This rapidly evolving process creates
Scientists have discovered that the human brain understands spoken language in a way that closely resembles how advanced AI language models work. By tracking brain activity as people listened to a long podcast, researchers found that meaning unfolds step by step—much like the
A new study suggests that micro-doses of THC could help counter many long-term side effects of HIV treatment without causing intoxication. In animal models, low-dose THC reduced inflammation, improved gut bacteria, boosted serotonin, and lowered harmful cholesterol and bile
Mountain regions around the world are heating up faster than the lands below them, triggering dramatic shifts in snow, rain, and water supply that could affect over a billion people. A major global review finds that rising temperatures are turning snowfall into rain, shrinking
In the icy waters of Alaska's Bristol Bay, a new study reveals how a small population of beluga whales (Delphinapterus leucas) survive the long haul through a surprising strategy: they mate with multiple partners over several years. The combination of long-term genetics,
Scientists at Stanford Medicine have discovered a treatment that can reverse cartilage loss in aging joints and even prevent arthritis after knee injuries. By blocking a protein linked to aging, the therapy restored healthy, shock-absorbing cartilage in old mice and injured
Researchers report that vagus nerve stimulation helped many people with long-standing, treatment-resistant depression feel better—and stay better—for at least two years. Most participants had lived with depression for decades and had exhausted nearly every other option. Those
China's economy met the government's official growth target in 2025, with official figures showing real gross domestic product (GDP) expanded by 5%.
As the US administration led by Donald Trump has continued to reassert its interest in owning Greenland, Europe has become more and more concerned about the security situation in the Arctic.
Look down at the rainforest floor. Rotting flowers shift under the assault of tiny petal-eating beetles. Vividly colored fungi pop up everywhere like the strange sculptures of a madly productive ceramicist.
Our planet has experienced dramatic climate shifts throughout its history, oscillating between freezing "icehouse" periods and warm "greenhouse" states.
Repairs to a collapsed wastewater pipe in Tijuana have been completed, with flows to the Tijuana River now stopped, the U.S. International Boundary and Water Commission announced on Jan. 19.
