Your brain's "stop eating" signal may come from an unexpected source. Researchers found that astrocytes--once thought to just support neurons--actually play a key role in controlling appetite. After a meal, glucose triggers tanycytes, which send ...

Scientists have identified a little-known receptor, GPR133, as a powerful regulator of bone strength. By activating it with a newly discovered compound called AP503, they were able to boost bone density in mice and counteract osteoporosis-like damage ...

Scientists have identified a potential new weapon against hepatitis E, a virus with no approved treatment and tens of thousands of deaths each year. The drug bemnifosbuvir, currently in trials for hepatitis C, was found to block the virus from ...

Scientists in Canada have uncovered a surprising weakness in glioblastoma, one of the deadliest brain cancers. They found that certain brain cells--once believed to only support healthy nerves--can actually help tumors grow by sending signals that .. ...

Scientists have uncovered a powerful new clue in the mystery of brain aging: a single protein called FTL1. In aging mice, higher levels of this protein weakened connections between brain cells and led to memory decline. But when researchers reduced . ...

Scientists have created an artificial saliva using a sugarcane protein that can protect teeth and fight bacteria. The key ingredient, CANECPI-5, binds directly to enamel, forming a shield against acids that cause decay. Early tests show it works even ...

A new study reveals that gut bacteria and metabolites may hold the key to detecting serious digestive diseases earlier and more easily. Using AI, scientists found that biomarkers linked to one condition can often predict others, showing these ...

Many people think that occasional binge drinking is harmless if they otherwise drink in moderation, but new research suggests that assumption may be dangerously wrong. A large U.S. study found that people with metabolic dysfunction-associated ...

Warming across the U.S. is far more uneven than it looks at first glance. While only about half of states show rising average temperatures, most are heating up in specific ways--like hotter highs or warmer lows. These hidden shifts vary by region, .. ...

Astrocytes, once thought to be mere brain "support cells," are now revealed to be key players in fear memory. Researchers found they actively help form, recall, and weaken fear responses by interacting with neurons in real time. Changing astrocyte .. ...
