Tears for fears: Juvenile mice secrete a protective pheromone in their tears, blocking adult mating

While looking for novel pheromones that can control different instinctive mouse behaviors, researchers have discovered a pheromone found only in the tears of young mice. Their experiments showed that this molecule protects prepubescent mice from mating activity by adult male mice. The research provides the first step toward a detailed understanding of how a sensory system can regulate social behavior.
