In mice, a kind of immune memory appears to protect the cells against future harm, a finding that could provide insight into treatments for irritable bowel syndrome and other inflammatory digestive conditions.

A polymer tube regenerates damaged nerves in monkeys, restoring near full functionality.

The silicon chips receive and send electrical signals, recreating activity from neurons in the rat brain that play a role in breathing and thinking.

The treatment will be tested in a handful of patients who suffered nerve damage in sports or traffic accidents.

When peripheral nerves are severed, Schwann cells at the injury site begin to proliferate and exhibit stem cell-like gene expression patterns.

Using diffusion-weighted tractography, scientists can produce a detailed image of the minute neural fibers within a mouse brain.  

A combination of visual stimulation and chemical growth promotion leads damaged retinal nerves to regenerate in mice.

Developing nonaddictive drugs to combat pain

Scientists hope an understanding of nerve fibers responsive only to gentle touch will give insight into the role the sense plays in social bonding.

A honeycomb-shaped scaffold helps damaged nerves reconnect, providing hope that a similar scaffold could someday enable nerves repair in vivo.
