Research Behind the News: Is Marriage Good for Your Health?

The News: In 1858, a British epidemiologist named William Farr set out to study what he called the “conjugal condition” of the people of France... Using birth, death and marriage records, Farr analyzed the relative mortality rates of the three groups at various ages. The work, a groundbreaking study that helped establish the field of medical statistics, showed that the unmarried died from disease “in undue proportion” to their married counterparts.

Research news: You are what your mother ate

The News: The placentas of female fetuses proved most sensitive to maternal diet, producing more of a protein that responds to estrogen, say researchers led by Cheryl Rosenfeld, a reproductive biologist at the University of Missouri in Columbia. The extra sensitivity could make female offspring more susceptible to estrogen-mimicking chemicals in the environment. More from a March 8, 2010 article in Science News by Tina Hesman Saey.

Research News: Global Warming & Arctic Sea Methane?

The News: Scientists studying global warming in the Arctic have discovered a previously unknown source of methane working its way into the atmosphere, a source that is releasing large amounts of the gas each year. Methane is, molecule for molecule, a far more potent global-warming gas than carbon dioxide. The newly discovered emissions are welling up from the continental shelf off Siberia's northern coast.

Research News: Alcohol and aggression in large men

The News:

As St. Patrick’s Day approaches, it may pay to keep in mind that there is a kernel of truth to the stereotype that large men are especially prone to being DWI — dangerous while intoxicated.
When they were drunk, bigger men became especially aggressive when given the opportunity to administer electric shocks to a fictitious opponent in a laboratory contest, say psychologist Nathan DeWall of the University of Kentucky in Lexington and his colleagues. Yet larger men showed no aggression increases after downing a nonalcoholic placebo drink. More in Science News, by Bruce Bower.
