Sun et al. show that mice exhibit reviving-like behaviors toward unconscious or dead conspecifics, escalating from sniffing to licking and tongue-pulling, which can aid recovery and are driven by oxytocin. Open-access paper here: doi.org/10.1126/scie...

Reviving-like prosocial behavior in response to unconscious or dead conspecifics in rodents
Whereas humans exhibit emergency responses to assist unconscious individuals, how nonhuman animals react to unresponsive conspecifics is less well understood. We report that mice exhibit stereotypic b...
