Ozempic may work in the brain in almost the opposite way scientists expected, activating hunger-linked neurons that appear essential for sustaining fat loss. The surprising discovery in mice could reveal new targets for developing even more effective o…

Knee osteoarthritis can seriously affect mobility and quality of life, but its progression isn’t completely out of your control. Exercise, stronger leg muscles, a healthier diet, and even modest weight loss can dramatically reduce stress on the knees a…

Specialized brain scans reveal that schizophrenia is linked to widespread loss of the synapses that connect brain cells, with the left side of the brain hit especially hard. The damage follows a surprisingly organized pattern tied to the brain’s chemis…

The human family tree may be due for a major rewrite. Researchers argue that Australopithecus and Paranthropus should be folded into the genus Homo because new fossils have blurred many of the traits once used to separate them. The proposed shake-up co…

The “Asian Water Tower” is losing roughly 24.2 billion tonnes of groundwater every year, with some of the worst declines hitting densely populated farming regions. Glacier melt may temporarily soften the crisis around the 2060s, but without changes in …

Extreme experiments have revealed how diamond behaves at crushing pressures beyond those inside Neptune and Uranus, resolving a decades-old conflict between theory and observation. The results could help scientists boost fusion energy output while reve…

A discarded SpaceX Falcon 9 stage crashed into the Moon on Aug. 5, leaving behind a newly formed crater about 60 feet wide. NASA’s Lunar Reconnaissance Orbiter captured detailed images showing bright and dark streaks of debris blasted across the surrou…

Spain’s total solar eclipse delivered an unexpected sight: a corona glowing gold instead of its usual pearly white. Because the Sun was setting, its light passed through more atmosphere, while smoke from nearby wildfires filtered out even more blue lig…

More than 1,000 genetic switches behave differently in male and female immune cells, helping explain why women are much more vulnerable to autoimmune diseases such as lupus. Female immune systems appear genetically tuned for stronger inflammatory respo…

Researchers have developed a new way to turn ordinary antibodies into tiny disease-fighting molecules that can work inside human cells, potentially opening new paths for treating Alzheimer’s, Parkinson’s, Huntington’s disease, and motor neurone disease…

MIT physicists found that two electronic phases inside the same quantum material emerge through surprisingly different mechanisms—one smoothly and the other in expanding pockets resembling growing ice crystals. The discovery could help explain how exot…

The brain has a remarkably flexible system for handling uncertainty and changing situations. Researchers found that the frontoparietal cortex constantly shifts how it communicates with other brain regions depending on what information is needed to make…
