Hormones, Not Just Love, Make Moms Tough Well, that's not all of the story. It turns out that the fierce behavior that compels a mother to risk her own life in defense of her young may depend as much on chemistry and biology as on a mother's love. Researchers at the University of Wisconsin-Madison have found evidence that a mother's protective behavior is regulated somewhat by the presence of a peptide hormone that is present in nearly all animals, including humans and mice. http://tinyurl.com/4trgs _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
