Scientists may be able to reliably forecast Antarctic ice loss through the middle of this century, offering governments a vital head start on sea level rise. After that, unstable ice retreat could accelerate dramatically, making the future much ...

NASA is preparing for future astronaut landings on the Moon with an unusually ambitious orbital rehearsal. During Artemis III in 2027, Orion astronauts will rendezvous and dock separately with prototype lunar landers from Blue Origin and SpaceX, ...

A giant planet had been hiding inside one of astronomy's most closely studied planetary systems, concealed by a bright disk of cosmic dust. Webb revealed Beta Pictoris d through atmospheric traces of carbon monoxide, water vapor, and methane, ...

Researchers have developed a fluoride-free gel that could help rebuild damaged tooth enamel, something the body cannot naturally replace once it is lost. Inspired by the proteins that guide enamel formation in infancy, the gel fills microscopic ...

A plant-derived compound reduced swelling, inflammation, and joint damage in rats with rheumatoid arthritis. It also helped rebalance immune activity and improve the way certain fats were processed in the body. Researchers say the findings could lead ...

Researchers found that specific brain circuits help decide which jobs bees perform as they age. When those circuits were switched off, older worker bees began caring for the queen again instead of carrying out their normal later-life duties. The ...

Ancient fern savannahs may have transformed parts of Europe into a wildfire-prone inferno during the end-Triassic mass extinction. New fossil evidence suggests the ferns repeatedly regrew after fires, creating fresh fuel that helped prolong the ...

Colorectal cancer is now the leading cause of cancer death among people under 50, and cases in younger adults continue to rise. Warning signs can include persistent bowel changes, recurring rectal bleeding, dark or narrow stools, unexplained weight . ...

Miniature brain models grown from patients' cells revealed striking differences in how Alzheimer's-related tissue responds to an antidepressant. The organoids and the particles they release could eventually guide more personalized treatments and ...

Researchers discovered a proton-assisted mechanism that greatly improves how triplet energy moves between quantum dots and nearby molecules. The proton briefly shifts position, helps coordinate electron movement, and then returns to where it started. ...
