Mice Display CPR-Like Behavior to Aid Unconscious Peers

Scientists document instinctive first-aid behaviors in rodents, resembling human emergency responses.

Researchers observed mice attempting to revive unconscious companions through actions like tongue-pulling and airway clearing.
The study, published in *Science*, found these behaviors to be reminiscent of human CPR techniques and likely instinctive rather than learned.
Mice were more likely to aid familiar peers than strangers, suggesting social recognition influences their behavior.
The actions were linked to oxytocin release in the brain, a hormone associated with social bonding and emotional responses.
This is the first documented evidence of such detailed emergency responses in animals as small as mice, adding to research on altruistic behaviors across species.
