The hormone oxytocin has come under intensive study in light of emerging evidence that its release contributes to the social bonding that occurs between lovers, friends, and colleagues. Oxytocin also plays an important role in birth and maternal behavior, but until now, research had never addressed the involvement of oxytocin in the transition to fatherhood.

The more economically dependent a man is on his female partner, the more likely he is to cheat on her, according to research to be presented at the 105th Annual Meeting of the American Sociological Association.

Aggressive and hyperactive boys with low parental monitoring are more likely to befriend deviant peers and become heavy drug users as teens, according to a new study published in the journal Addictive Behaviors. Yet the investigation by scientists from the Université de Montréal and Sainte-Justine University Hospital Research Center found that bad boys can be protected from heavy substance use as teenagers if they are highly monitored and befriend good boys as children.

A large prospective study of 5033 men and women in the Tromsø Study in northern Norway has reported that moderate wine consumption is independently associated with better performance on cognitive tests. The subjects (average age 58 and free of stroke) were followed over 7 years during which they were tested with a range of cognitive function tests. Among women, there was a lower risk of a poor testing score for those who consumed wine at least 4 or more times over two weeks in comparison with those who drink < 1 time during this period The expected associations between other risk factors for poor cognitive functioning were seen, i.e. lower testing scores among people who were older, less educated, smokers, and those with depression, diabetes, or hypertension.

Keep your heart healthy and you may slow down the aging of your brain, according to a new study reported in Circulation: Journal of the American Heart Association.

By stimulating certain areas of the brain, scientists can alleviate the effects of disorders such as depression or Parkinson's disease. That's the good news. But because controlling that stimulation currently lacks precision, over-stimulation is a serious concern — losing some of its therapeutic benefits for the patient over time.

A new study shows that a sleep disorder may be a sign of dementia or Parkinson's disease up to 50 years before the disorders are diagnosed. The research is published in the July 28, 2010, online issue of Neurology®, the medical journal of the American Academy of Neurology.

A new study from researchers at the Harvard School of Public Health (HSPH) and Children's Hospital Boston has found that gay men, lesbians, bisexuals, and heterosexuals who have ever had a same-sex sex partner are one-and-a-half to two times as likely to experience violent events, especially in childhood, than the general population and have double the risk of experiencing posttraumatic stress disorder (PTSD) as a consequence of these events. It is the first study to directly link higher rates of PTSD in those four groups (classified as sexual minorities) to greater violence exposure.

Gay men can recall familiar faces faster and more accurately than their heterosexual counterparts because, like women, they use both sides of their brains, according to a new study by York University researchers.

A new Brigham Young University study adds our social relationships to the "short list" of factors that predict a person's odds of living or dying.
