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

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, ...

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, ...

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 ...
