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 sen…

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 FTL…

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 …

A newly identified gene mutation may help explain why schizophrenia patients struggle to update their understanding of reality. The mutation disrupts a brain circuit involved in flexible decision-making, causing mice to stick with outdated choices even…

Deep sleep does far more than rest the body — it activates a powerful brain-driven system that controls growth hormone, fueling muscle and bone strength, metabolism, and even mental performance. Scientists have now mapped the neural circuits behind t…

After a stroke, the brain may do something surprisingly hopeful—it can “refresh” parts of itself. Researchers analyzing brain scans from over 500 stroke survivors found that while the damaged side of the brain appears to age faster, the opposite,…
