Substantially more men than women favor routine paternity testing when a baby is born, according to a recent University of Washington survey, but the surprise to researchers is that the percentage of men favoring such testing wasn't higher.

Researchers find signs of grain milling, baking 23,000 years ago
Archaeologists have found strong evidence that wheat and barley were refined into cereals 23,000 years ago, suggesting that humans were processing grains long before hunter-gatherer societies developed agriculture.

Gene clusters predict atherosclerosis severity, susceptibility
Duke University Medical Center researchers have identified specific clusters of genes within human aortas that appear to predict with great specificity which patients may be at highest risk for developing atherosclerosis, as well as the severity of the disease.

Study: Emission of smog ingredients from trees is increasing rapidly
Changes in U.S. forests caused by shifts in land use practices may have inadvertently worsened ozone pollution, according to a study led by Princeton University scientists.

Mathematical analysis: It may not be possible to create 'perfect lens'
Researchers at Purdue University and the Massachusetts Institute of Technology have completed a mathematical analysis showing that it isn't quite possible to build a so-called

Giving computers the jitters helps explain human behavior
Penn State researchers have developed a computer program that mimics the results when a human appraises a task as threatening and feels worried before starting.

Climate change a focus of new NSF-supported research on how decisions are made in a world
Five interdisciplinary research teams will share some $25 million from the National Science Foundation (NSF) over the next five years to study important aspects of problems associated with understanding climate-related decisions under uncertainty.

Winning combination to build bone density in children
Few studies have examined the interactive effects of calcium intake and activity, especially ones that differentiate between the types of activity that most positively affect bone density.

Supernova warning system will give astronomers earlier notice
A Supernova Early Warning System (SNEWS) that detects ghostlike neutrino particles that are the earliest emanations from the immense, explosive death throes of large stars will alert astronomers of the blasts before they can see the flash.

Good vibrations in the nanoworld
Accessing vibrational modes of molecular chains at the site of a specific atom in molecules is no longer a dream.

Depression also a problem in patients with Parkinson's
While Parkinson's disease typically brings to mind symptoms such as tremors and slow movement, researchers have found that nearly half of all Parkinson's patients also suffer from depression.

High resolution satellite imagery assists hunt for infectious 'kissing bugs'
In the midst of crammed slums in the Nicaraguan district of Matagalpa, aid workers are hunting house-to-house for hidden killers, their search guided by high-resolution satellite imagery supplied through an ESA-backed project.

MR imaging during brain surgery improves tumor removal
A specially adapted magnetic resonance imaging (MRI) scanner can help physicians remove brain tumors and all of the residual cancer during one surgical procedure, according to a study published in the October issue of the journal Radiology. Using intraoperative MR-guidance, surgical strategy was changed in one out of four cases.
