During the early stages of a pandemic, viruses tend to evolve in ways that enhance their ability to reproduce and spread, ...

Brain tissue is an optical mess. Water, lipids, and tangled cellular membranes all bend light in different directions. If ...

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, ...

A team of researchers in Germany has frozen adult mouse brain tissue at cryogenic temperatures and, after thawing it, recorded electrical activity that closely resembled normal function. The work, ...

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 ...

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 ...

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 ...
