For decades, Alzheimer’s disease has been framed as a one‑way slide, with treatments aiming only to slow the descent. Now a cluster of animal studies is challenging that assumption, showing that ...

Capitalizing on the flexibility of tiny cells inside the body's smallest blood vessels may be a powerful spinal cord repair strategy, new research suggests. In mouse experiments, scientists introduced ...

Endogenous lithium levels were lower in the prefrontal cortex of people with Alzheimer's and mild cognitive impairment. Lithium depletion in mouse models led to increased amyloid and accelerated ...

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, ...

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 ...

A female mouse from China's Tiangong Space Station has given birth to 28 pups across three healthy litters since her return, each exceeding normal sizes and adapting faster to Earth.

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 ...
