First aider mice seen trying to bring their 'freshly deceased' friends back to life

Mice appear to administer first -aid if they find a fellow mouse unconscious, scientists have discovered.

They attempt to revive companions by licking at their faces, or even by pulling at their mouths or tongues.

Mice spent an average of 47% of the 13-minute test interacting with an unconscious partner.

The more intense grooming behaviors were correlated with better recovery.
