A drug combo widely explored for anti-aging may actually damage the brain, according to new mouse research showing severe loss of myelin and changes linked to "chemo brain." Surprisingly, the damaged cells resembled those seen in multiple sclerosis, ...

A new experimental treatment could finally offer hope for millions of people with dry age-related macular degeneration -- one of the leading causes of blindness in older adults. Researchers at Aalto University discovered a way to gently heat tissue . ...

A giant planet nearly 700 light-years away has a bizarre daily weather cycle where mineral clouds appear every morning and vanish by nightfall. Using the James Webb Space Telescope, astronomers discovered that WASP-94A b's mornings are filled with .. ...

NASA's Fermi telescope has detected what may be the first confirmed gamma-ray signal from a superluminous supernova -- one of the most extreme explosions in the universe. Scientists believe the blast was powered by a rapidly spinning magnetar, an ...

Researchers found that drinking guava juice may significantly improve anemia by helping the body absorb iron more efficiently. In a review of 17 studies, women and teenage girls who consumed guava juice -- especially with iron supplements -- ...
