Epaulette sharks can reproduce without any measurable increase in energy use, stunning researchers who expected egg-laying to be costly. Scientists tracked metabolism, blood, and hormone levels through the entire reproductive cycle and found ...

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 .. ...

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 ...

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 ...

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 ...

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 .. ...

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 ...

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 ...

Scientists have uncovered why people with chronic kidney disease so often die from heart problems: damaged kidneys release tiny particles into the bloodstream that actively poison the heart. These particles, produced only by diseased kidneys, carry . ...

Researchers have identified a key molecular interaction that accelerates Parkinson's disease by damaging the brain's energy systems. They designed a new treatment that intercepts this harmful process, protecting brain cells and restoring their ...
