Scientists are addressing the threat of antimicrobial drug resistance by launching two new clinical trials aimed at prolonging the effectiveness of currently available antibacterial drugs. The concept underlying both studies: Less is more.
The U.S. has taken the next step toward construction of the revolutionary Ocean Observatories Initiative (OOI): a network of ocean observing components, and their associated cyberinfrastructure, that will allow scientists to examine ocean processes on global, regional and coastal scales.
Genes that regulate the energy consumption of cells have a different structure and expression in type II diabetics than they do in healthy people, according to a new study from the Swedish medical university Karolinska Institutet published in
Blacksburg, Va. — Virginia Tech’s nuclear engineering program will receive 0,000 for faculty development and 9,948 for fellowships from the Nuclear Regulatory Commission (NRC).
Analysis of ancient DNA from skeletons suggests that Europe’s first farmers were not the descendants of the people who settled the area after the retreat of the ice sheets. Instead, the early farmers probably migrated into major areas of central and eastern Europe about 7,500 years ago, bringing domesticated plants and animals with them, says Barbara Bramanti from Mainz University in Germany and colleagues. The researchers analyzed DNA from hunter-gatherer and early farmer burials, and compared those to each other and to the DNA of modern Europeans. They conclude that there is little evidence of a direct genetic link between the hunter-gatherers and the early farmers, and 82 percent of the types of mtDNA found in the hunter-gatherers are relatively rare in central Europeans today.
An innovative collaboration among UC Davis engineers, physicists and radiologists has resulted in the first-ever fully 3-D breast imaging technique that uses both high-resolution PET and CT scanning.
A harmless shard from the shell of a common childhood virus may halt a biological process that kills a significant percentage of battlefield casualties, heart attack victims and oxygen-deprived newborns, according to research presented Sunday, September 6, 2009, at the 12th European meeting on complement in human disease in Budapest, Hungary.
Drug treatment options for depression can take weeks for the beneficial effects to emerge, which is clearly inadequate for those at immediate risk of suicide. However, intravenous (IV) ketamine, a drug previously used as an anesthetic, has shown rapid antidepressant effects in early trials.
As public health experts warn of potential widespread outbreaks of H1N1 flu this school year, a new study from North Carolina State University shows that students do not comply with basic preventative measures as much as they think do. In other words, the kids aren’t washing their hands.
People with mental illnesses such as depression and anxiety are the heaviest smokers in the country, but their doctors are afraid to ask them to quit. They assume that if their patients try to quit smoking, their mental disorders will get worse.
