A discovery in molecular chemistry may help remove a barrier to widespread use of diesel and other fuel-efficient "lean burn" vehicle engines. Researchers at the Department of Energy's Pacific Northwest National Laboratory have recorded the first observations of how certain catalyst materials used in emission control devices are constructed.
Wellcome Trust Sanger Institute scientists have developed a new large-scale method to identify the interactions between proteins that are a major target for therapeutic intervention. The novel method can identify the weak, short-lived interactions that are characteristic of cell responses to cues from the environment or from within the body.
American adults have a higher prevalence of stroke than their European counterparts, due in part to a higher rate of stroke risk factors among Americans and barriers to care in the United States, according to a study presented at the American Stroke Associations International Stroke Conference 2008.
Compared to European men, U.S. men had 61 percent higher odds of having a stroke and U.S. women had almost twice the odds of stroke as European women.
New York, February 21, 2008 Premature birth can have serious effects on the development and growth of children. In many parts of the world, preterm deliveries are increasing in frequency. In a study published in the February 2008 issue of the American Journal of Obstetrics & Gynecology, researchers from the University of Porto Medical School and the Hospital S. João, Porto, Portugal, found that there was a strong link between physical abuse during pregnancy and premature births.
The finding, appearing online in the journal Circulation, is the first to document a genetic mutation linked to PAD. Although the work was done in mice, researchers say it is likely to give them new insight into how PAD develops and progresses in humans.
Expressive writing --writing about ones deepest thoughts and feelings—may help change the way cancer patients think and feel about their disease. In one of the first studies published in an oncology journal about the benefits of writing therapy, researchers say those who immediately reported changes in thoughts about their illness also reported a better physical quality of life three weeks later.
DENVER-A University of Denver study shows a curriculum-based bullying prevention program reduced incidents of bullying by 20 percent, twice as much as in the study control group.
Jeffrey M. Jenson and William A. Dieterich of the University of Denvers Graduate School of Social Work studied more than 1,100 students in 28 elementary schools in Denver public schools. One group was exposed to a bullying prevention program called Youth Matters (YM). A second control group of students was not.

Outer space will rocket into reality as the getaway of this century, according to researchers at the University of Delaware and the University of Rome La Sapienza.
COLUMBIA, Mo. University of Missouri scientist Ray Semlitsch studies creatures most people dont ever see. These creatures are active only at night and thrive in the shallow, cool, wet surroundings of headwater streams, an oft-overlooked biological environment.
