Anxiety is often described as a whole‑brain problem, but a series of mouse experiments suggests that, in some cases, a single misfiring circuit can tip the balance between calm and fear. By nudging ...

Research in mice identifies brain circuitry that supports certain reward-based decisions. Every day, our brain makes thousands of decisions, big and small. Any of these decisions -- from the least ...

In a lab far from the woolly mammoth’s icy plains, researchers from Colossal Biosciences have successfully brought a tiny “woolly mouse” to life. Here’s what it could mean for de-extinction. A tiny, ...

Every day, our brain makes thousands of decisions, big and small. Any of these decisions - from the least consequential such as picking a restaurant to the more important such as pursuing a different ...

A small brown mouse has just done something no mammal has ever done before: give birth on Earth after spending part of its reproductive cycle in orbit. It sounds like a quirky space trivia item, but ...

Aubrey de Grey describes his plan to get combinations of promising aging damage-repair approaches. Aging is accumulated molecular and cellular damage from metabolism, leading to pathology. He ...

Study in mice offers insights into the brain circuitry underlying certain types of reward-based choices. Researchers identified distinct groups of brain cells activated when animals anticipate a ...
