The longevity-linked APOE2 gene appears to protect brain cells by reducing DNA damage and helping neurons recover from stress. The finding could open a new path toward treatments that mimic APOE2's defenses in people at higher genetic risk for ...

A large study suggests that GLP-1 drugs including Ozempic and Mounjaro may slightly increase the risk of hair loss in people with type 2 diabetes. Compared with two other common classes of diabetes medications, GLP-1 users had a significantly higher ...

A massive genetic study has identified nine new genes linked to hyperemesis gravidarum, the most severe form of pregnancy sickness, bringing the total number of known risk genes to ten. The discoveries provide fresh insight into why some women ...

A global shift toward healthier diets could sharply reduce livestock farming, free up agricultural land, and cut emissions from land-use change by 85% by 2050. At the same time, fruit, vegetable, nut, and legume production could soar, creating a ...

A 25-year study found that frequent consumption of soda, sports drinks, and fruit juice beginning in childhood was linked to a higher risk of high blood pressure in adulthood. Swapping one daily drink for whole fruit, milk, or water could ...

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 ...

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 ...
