A surprising stress-related signal may help the brain repair itself after injury. Researchers found that myelin-producing precursor cells rapidly release the stress hormone CRH near damaged brain ...

Scientists have found that the AMOC may be far more vulnerable to rapid warming than to temperature alone. When warming happens slowly, the ocean can adapt, but at faster rates similar to today’s, the ...

Astronomers have released more than three million new spectra in a sweeping expansion that, for the first time, brings SDSS-V optical observations to the Southern Hemisphere. The data reveal ...

Orange juice may have a much bigger effect on the body than scientists once realized. Drinking it regularly appears to influence genes tied to inflammation, blood pressure, metabolism, and blood sugar ...

Ancient remains from Vietnam suggest diseases like yaws may have been passed from mother to child thousands of years ago, a ...

Scientists probing life’s deepest origins have uncovered evidence that the first free-living cells may have emerged not once, but twice. The findings suggest a striking possibility: life may share one ...

Ordinary WiFi networks could quietly become powerful surveillance tools, allowing people to be identified without cameras, special sensors, or even carrying a connected device. Researchers showed that ...
