Intelligence Is in the Genes, but Where?
You can thank your parents for your smarts—or at least some of them. Psychologists have long known that intelligence, like most other traits, is partly genetic. But a new study led by psychological scientist Christopher Chabris of Union College reveals the surprising fact that most of the specific genes long thought to be linked to intelligence probably have no bearing on one’s IQ. And it may be some time before researchers can identify intelligence’s specific genetic roots. Chabris and David Laibson, a Harvard economist, led an international team of researchers that analyzed a dozen genes using large data sets that included both intelligence testing and genetic data.

Craving an Ice-Cream Fix
The New York Times: The notion that food can be addictive has been debated for some time and largely rejected by both nutrition and addiction researchers. But this spring, the secretary of health, Kathleen Sebelius, said that for some, obesity is “an addiction like smoking.” One month earlier, Dr. Nora Volkow, director of the National Institute on Drug Abuse, gave a lecture at Rockefeller University, making the case that food and drug addictions have much in common, particularly in the way that both disrupt the parts of the brain involved in pleasure and self-control.

Study: Oxytocin (‘The Hormone of Love’) Also Makes Us Conformists
The Atlantic: PROBLEM: Oxytocin, which you may also know as "the hormone of love," is the driving force behind sociability, trust, and generosity. It enables everything from mother-child bonding to orgasms, and it's one of the main things that sociopaths lack. The catch is that it strictly promotes in-group love -- and so it can't be used to kumbaya away cultural and political conflicts. Since oxytocin causes favoritism, might it also contribute to group conformity? METHODOLOGY: You can get oxytocin release by shaking someone's hand or hugging a loved one.

Failure Is an Option
Parents Magazine: Whenever Helena Bogosian takes her daughters, Margot, 5, and Nina, 4, out to eat, she asks if they can have the same toy in their kids' meal so neither feels slighted. But one time the girls got different things because the restaurant had run out of the plastic grasshoppers they both wanted. Margot started crying hysterically, so the Tenafly, New Jersey, mom drove to four more franchises in fruitless pursuit of matching toys. By the time she gave up, it was dark, the kids were fast asleep in their car seats, and she felt foolish. "I learned that avoiding a child's disappointment can be harder than helping her deal with it," she says.

Study: More women winemakers are making names for themselves
The Washington Post: In 1978, the first vintage that Cathy Corison made wine, she could count on one hand the number of women she knew of doing the same kind of work in the cellars of the Napa Valley. Without using all her fingers. Nearly 35 years later, Corison needs a lot more fingers. Winemaking remains primarily a man’s world, but research by Santa Clara University professors Lucia Albino Gilbert and John Gilbert has found that nearly 10 percent of California wineries now have women as the main or lead winemaker. Their second finding: Women winemakers tend to be more highly acclaimed than their male counterparts. Why?

Why Misinformation Sticks and Corrections Can Backfire
TIME: At the height of campaign season in any presidential election year, voters will be inundated with all kinds of information of dubious accuracy, from misleading claims about candidates’ personal lives to exaggerations about their policy differences. Unfortunately, it’s precisely this type of misinformation — the kind that hews to people’s preexisting political, religious or social ideology — that sticks. As a new review of past research concludes, “mud” sticks — and, worse, attempts to correct erroneous beliefs can backfire, reinforcing the very misrepresentations they aim to erase.
