The News: Scientists have long known what psychopaths lack: emotions like empathy, fear and remorse. Now, a new study focuses on what they may have, a brain abnormality that may lead them to seek rewards like money, sex or fame at any cost. More from NPR, All Things Considered, 3/27/2010.

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: Dog Origins Tracked to Middle East
The News: Borrowing methods developed to study the genetics of human disease, researchers have concluded that dogs were probably first domesticated from wolves somewhere in the Middle East, in contrast to an earlier survey suggesting dogs originated in East Asia.

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.

Research News: Faster internet possibilities, among other things
The News: A new, more efficient low-cost microring resonator for high speed telecommunications systems has been developed and tested by Professor Roberto Morandotti's INRS team in collaboration with Canadian, American, and Australian researchers. This technological advance capitalizes on the benefits of optical fibers to transmit large quantities of data at ultra-fast speeds. Read more in ScienceDaily.
