When a nerve is injured, it's often hard to get it to regrow fast enough to restore function.

But now researchers say they can speed up that process, so that damaged nerves can be healed in days instead of months — at least in rats.

"People like me, that the State Department no longer wants, but for some reason can't or won't fire, are assigned to what we call 'hallwalking,'" says author Peter Van Buren.
