A new study reveals that astrocytes, once dismissed as mere support cells, play a central role in fear memory.

Picture a star-shaped cell in the brain, stretching its spindly arms out to cradle the neurons around it. That's an astrocyte, and for a long time, scientists thought its job was caretaking the brain, ...
