New research shows young women are less likely than young men ever to have considered running for office, to express interest in a candidacy at some point in the future, or to consider elective office a desirable profession. Fuente : http://www.eurekalert.org/pub_releases/2013-03/au-...

Researchers at The Ohio State University have uncovered an obstacle to the cone-guided approach to fast-ignition fusion energy through simulations at the Ohio Supercomputer Center and experiments at the National Ignition Facility. Chris Orban, Ph.D., a researcher at Ohio State and the lead theorist...

The nation's 40 federally-funded research and development centers spent $17.8 billion on research and development in fiscal year 2011, according to a recent report from the National Science Foundation. More than $850 million of the total was supplied by funds from the American Recovery and...

In a National Science Foundation funded study, Kathleen Alexander, an associate professor of wildlife at Virginia Tech, found that climate drives a large part of diarrheal disease and increases the threat that climate change poses on vulnerable communities.The only study of its kind in Sub-Saharan...

A psychological experiment known as "the marshmallow test" has captured the public's imagination as a marker of self control. This test shows how well children can delay gratification, a trait that has been shown to be as important to scholastic performance as traditional IQ.New research from...

Existing Lyme disease tests assess the presence of antibodies, which take weeks to form after the initial infection and persist after the infection is gone. Now, a nanotechnology-inspired technique developed by researchers at the University of Pennsylvania may lead to diagnostics that can detect...

Biologists have found that neural-crest stem cells--multipotent, migratory cells unique to vertebrates that give rise to facial bones, smooth muscle, and other structures -- also play a key role in building the nose's olfactory sensory neurons, the only neurons that regenerate throughout adult...

Solutions that meet the broad, varied, and often competing priorities of conservation are difficult to come by. New research takes a hard look at why, in an effort to find ways to resolve the issue. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/-...

For the first time, the complete genomes of three separate populations of aye-ayes -- a type of lemur -- have been sequenced and analyzed in an effort to characterize patterns of genetic diversity and help guide conservation efforts for the species. The aye-aye species is found only on the island...
