MBL, WOODS HOLE, MA -- Scientists have discovered that cells use a very simple phase transition -- similar to water vapor condensing into dew -- to assemble and localize subcellular structures that are involved in formation of the embryo.
A team of researchers, led by the University of Minnesota, addressing long-standing conflicts in ecology and evolutionary science, has provided key directions for the future of community ecology.
A new species of yeast has been discovered deep in the Amazon jungle. In a paper published on-line in FEMS Yeast Research, IFR scientists and colleagues from Pontificia Universidad Católica del Ecuador describe the novel characteristics of Candida carvajalis sp. nov.
New recommendations to limit the work hours of medical residents could cost the nation's teaching hospitals about $1.6 billion annually to hire substitute workers, according to a new report from the RAND Corporation and UCLA.
Those travelling abroad should take seriously advice to pack their condoms and keep their needles to themselves: research published today in the open access journal Retrovirology shows that tourists, travellers and migrants from Greece, Portugal, Serbia and Spain actively export HIV-1 subtype B to other European nations.
PROVIDENCE, RI ? Individuals with heart disease are twice as likely to suffer from depression as the general population, an association the medical community has largely been unable to explain.
Santa Barbara, California ? A team of researchers, addressing long-standing conflicts in ecology and evolutionary science, has provided key directions for the future of community ecology.
Four major US national laboratories have worked together to develop a computer model to help airport authorities screen passengers for pandemic influenza. The tool can help estimate false negatives, people with influenza who slip through the screening process, and so assess the risk of infected passengers unknowingly spreading disease across the nation.
For the first time UK scientists have shown what the food poisoning bug Salmonella feeds on to survive as it causes infection: glucose.
Their discovery of Salmonella's weakness for sugar could provide a new way to vaccinate against it. The discovery could also lead to vaccine strains to protect against other disease-causing bacteria, including superbugs.
Researchers have successfully tested first the first time a computer simulation of major portions of the body's immune reaction to influenza type A, with implications for treatment design and preparation ahead of future pandemics, according to work accepted for publication, and posted online, by the Journal of Virology.
AUSTIN, Texas?Scientists struggling to understand how Earth's climate will change in the next few decades have neglected a potential treasure trove of information?sediments deposited in the ocean by major Arctic rivers such as the Colville and Mackenzie rivers?according to geoscientists at The University of Texas at Austin and Texas A&M University.
BOSTON (May 18, 2009) Curcumin, the major polyphenol found in turmeric, appears to reduce weight gain in mice and suppress the growth of fat tissue in mice and cell models. Researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University (USDA HNRCA) studied mice fed high fat diets supplemented with curcumin and cell cultures incubated with curcumin.
ATS 2009, SAN DIEGO?Healthcare workers in South Africa are at a significantly increased risk of developing drug-resistant tuberculosis, or XDR-TB, in a trend which threatens to further exacerbate the already beleaguered healthcare systems in sub-Saharan countries, according to results of a new study.
ATS 2009, SAN DIEGO?Aside from the obvious and immediate health problems that patients undergoing mechanical ventilation face, those who recover often do so with profound loss of strength and mobility that can impair their daily functioning and even lead to increased risk of morbidity and mortality down the line.
Individuals suffering from chronic obstructive pulmonary disorder (COPD) can experience significant savings in healthcare costs by employing a self-treatment program with the judicious use of medications, according to the results of a new study. The self-treatment program achieves these savings by reducing the duration of flare-ups.
