A high-mileage, low-pollution car built by students at the University of California, Davis, will drive from Hockenheim, Germany to Paris, France between Sept. 22 and 25 as part of the Challenge Bibendum, a competition run by tire manufacturer Michelin to promote new technology in automobiles.
UC Davis is the only university represented among 70 participants including auto industry giants Ford, DaimlerChryser and Honda. Graduate students Eric Chattot, Thomas Dreumont and Charnjiv Bangar from the
Driven by precise new satellite measurements and sophisticated new computer models, a team of NASA researchers is now routinely producing the first global maps of fine aerosols that distinguish plumes of human-produced particulate pollution from natural aerosols.
In the current issue of the journal Nature, atmospheric scientists Yoram Kaufman, at NASAs Goddard Space Flight Center, Greenbelt, Md., Didier Tanré and Olivier Boucher from CNRS (Centre National de la Recherche Scientifique)
Study shows antioxidant takes no bite out of atherosclerosis in healthy people
LOS ANGELES, Sept. 17-Despite its early promise, taking vitamin E does not appear to slow the progression of atherosclerosis in healthy people, according to researchers from the USC Atherosclerosis Research Unit and colleagues.
Many believe that atherosclerosis, the thickening of artery walls that can lead to heart attack and stroke, results from oxidative damage to tissue in the artery wall cause
Folic acid is not only a safeguard against spina bifida and other birth defects in babies – it can also prevent heart disease and strokes, two of Northern Ireland’s biggest killers, according to research from the University of Ulster.
Research at the University has shown and folic acid and three other related B-vitamins can prevent the accumulation of a high blood level of homocysteine, a risk factor in heart disease and strokes.
The risk of high homocysteine is similar to the risk
Changes in the brains white matter may play a major role in the onset of Alzheimers disease, whose baffling origin has traditionally been blamed on the gray matter. The new findings could provide a fresh direction for Alzheimers research in this neglected part of the brain, offering the potential for early diagnosis and enhanced therapies.
The results are reported in the Sept. 17 print edition of Biochemistry, a peer-reviewed journal of the American Chemical Society, the w
Frustrated by the limitations of present numerical models that simulate how Earths climate will be altered by factors such as pollution and landscape modification, Duke University engineers are creating a new model incorporating previously-missing regional and local processes.
“The model we are developing is much more refined,” said the projects leader, Roni Avissar, chairman of the Department of Civil and Environmental Engineering at Dukes Pratt School of Engineering.
