A new technique for printing extraordinarily thin lines quickly over wide areas could lead to larger, less expensive and more versatile electronic displays as well new medical devices, sensors and other technologies.
Geologists from the University of Leicester propose that humankind has so altered the Earth that it has brought about an end to one epoch of Earth’s history and marked the start of a new epoch.
Jan Zalasiewicz and Mark Williams at the University of Leicester and their colleagues on the Stratigraphy Commission of the Geological Society of London have presented their research in the journal GSA Today.
In it, they suggest humans have so changed the Earth that on the planet the Holocene epoch has ended and we have entered a new epoch - the Anthropocene.
About nine percent of teenagers may have metabolic syndrome, a clustering of risk factors that put them on the path toward heart disease and diabetes in adulthood. This shocking statistic represents some of the first concentrated efforts to define and measure metabolic syndrome in children and adolescents – a necessary starting point for combating the problem, but one that has proven even trickier in youth than it has been in adults.
CHICAGO (January 25, 2008) Research in the January issue of the Journal of the American College of Surgeons (JACS) shows that many patients with minimal injuries are being transferred from community hospitals to Level I and II trauma centers, despite the ability of the community hospitals to treat such injuries. The study concludes that overuse of trauma centers threatens to limit the availability of resources to injured patients truly in need; increase overall system costs; and burden higher-level trauma centers with the routine care of minor injuries.
Blacksburg, Va. -- A group of computational biologists at Virginia Tech have created a mathematical model of the process that regulates cell division in a common bacterium, confirming hypotheses, providing new insights, identifying gaps in what is understood so far, and demonstrating the role of computation in biology.
Rapid evolution of a protein produced by an immunity gene is associated with increased antiviral activity in humans, a finding that suggests evolutionary biology and virology together can accelerate the discovery of viral-defense mechanisms, according to researchers at Fred Hutchinson Cancer Research Center in Seattle, Washington.
These findings, published January 25 in the open-access journal PLoS Genetics, present a striking example by which evolutionary studies can directly lead to biomedically important discoveries in the field of infectious diseases.
A group of Australian researchers at the Universities of Melbourne and New South Wales have developed new tools and paradigms to understand immune evasion from HIV. The study, published Friday, January 25 in PLoS Pathogens, shows that both prior vaccination and timing influence the rates of immune escape, providing further insight into the effectiveness of T cell immunity to HIV.
CAMBRIDGE, Mass. - For years, scientists have been trying to teach computers how to see like humans, and recent research has seemed to show computers making progress in recognizing visual objects. A new MIT study, however, cautions that this apparent success may be misleading because the tests being used are inadvertently stacked in favor of computers.
SEATTLE Rapid evolution of a protein produced by an immunity gene is associated with increased antiviral activity in humans, a finding that suggests evolutionary biology and virology together can accelerate the discovery of viral-defense mechanisms, according to researchers at Fred Hutchinson Cancer Research Center.
