People with Alzheimer’s disease have lower levels of lithium in their brains than those without cognitive impairment, and a deficiency of the metal appears to accelerate the accumulation of amyloid plaques and memory loss – but it could possibly be reversed with a small dose of lithium

Unexpected archaeological discoveries are rewriting the story of how the big, bad wolf became our first and most beloved pet

If the EPA abdicates its responsibility to address climate change, it will harm health and the planet in exchange for pandering to fossil fuel interests

Thanks to groundbreaking models and the James Webb Space Telescope, scientists are poised to explore their mysterious evolution and reveal clues about planetary formation across the galaxy.

International oversight would reduce risks, but could be "a politically sensitive and contentious matter."

Thirteen years into its mission, NASA's Curiosity rover is still uncovering Martian mysteries while learning to do more with less.

ESA’s Hera mission has captured images of asteroids (1126) Otero and (18805) Kellyday. Though distant and faint, the early observations serve as both a successful instrument test and a demonstration of agile spacecraft operations that could prove useful for planetary defence.

Hera is currently travelling through space on its way to a binary asteroid system. In 2022, NASA’s DART spacecraft impacted the asteroid Dimorphos, changing its orbit around the larger asteroid Didymos. Now, Hera is returning to the system to help turn asteroid deflection into a reliable technique for planetary defence.

The shooting star was part of the Perseid and Alpha Capricornids meteor showers.

The M4.4 solar flare unleashed a coronal mass ejection (CME) into space — and Earth might just receive a glancing blow.
