Ah, the Happy Face. That ubiquitous circle with the wide smile that is so irritating when used to dot i's, end sentences, punctuate instant messages or stand in for greetings in email. And yet, something about that silly grin also makes us a bit cheered up, even as we roll our eyes. Along those lines, Adam Guastella and colleagues at the Brain & Mind Research Institute, University of Sydney, Australia, have recently discovered that our responses to happy faces can be...

Oxytocin was originally studied as the "milk let-down factor," i.e., a hormone that was necessary for breast-feeding. However, there is increasing evidence that this hormone also plays an important role in social bonding and maternal behaviors. A new study scheduled for publication in the August 1st issue of Biological Psychiatry now shows that one way oxytocin promotes social affiliation in humans is by enhancing the encoding of positive social memories. Adam J. Guastella, Ph.D. and his...

New research at UT Southwestern Medical Center has found that high levels of ghrelin, a "hunger hormone", may have an antidepressant effect. The study may explain why some people overeat when they are stressed or depressed.An empty stomach releases ghrelin into the bloodstream, where it then moves to the brain triggering feelings of hunger. Researchers believe treatment with either ghrelin, or a drug intended to cancel its effects, may be able to help both people who eat too much and those...

The researchers hope this discovery will change in the way we think about and treat abdominal obesity.Yang identified that the hormone Neuropeptide Y...

Forgetful Casanovas are lucky in love. At least that's how University of Florida researchers interpret the results of new research on the mating habits and nervous systems of prairie voles.

Prairie voles, aka Microtus ochrogaster, are common native rodents in the central U.S. and southern Canada. Because they mate for...

The American College of Obstetricians and Gynecologists, however, say that labor should only be induced when it is more risky...

Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
