(CHICAGO) ?Simvastatin, a commonly used, cholesterol-lowering drug, may prevent Parkinson's disease from progressing further.
Australian scientists have found that the bacterium Cupriavidus metallidurans catalyses the biomineralisation of gold by transforming toxic gold compounds to their metallic form using active cellular mechanism.
When it comes to the two basic types of cells, prokaryotes and eukaryotes, compartmentalization is everything. Prokaryotes are evolutionarily ancient cells that only have a membrane surrounding their outer boundary, while the more complex eukaryotes have an outer membrane and membrane bound compartments within the cell.
BATON ROUGE -- For Sophie Warny, LSU assistant professor of geology and geophysics and curator at the LSU Museum of Natural Science, years of patience in analyzing Antarctic samples with low fossil recovery finally led to a scientific breakthrough.
Scientists have found the "Rosetta Stone" of supervolcanoes, those giant pockmarks in the Earth's surface produced by rare and massive explosive eruptions that rank among nature's most violent events. The eruptions produce devastation on a regional scale -- and possibly trigger climatic and environmental effects at a global scale.
LINCOLN, NE -- Just like the rest of us, golf courses show their age -- especially on putting greens, which experience more foot traffic than anywhere else on golf courses. Putting greens, which comprise only about 1.6% of the total area on most courses, require more intensive management than any other part of the course.
ROCHESTER, Minn. -- A national team of researchers led by scientists at Mayo Clinic has found that a common treatment for primary sclerosing cholangitis, a chronic liver disease, is not helpful for patients, according to a study published this month in the journal Hepatology.
Scientists at Scripps Institution of Oceanography at UC San Diego and their colleagues at Creighton University have deciphered the highly unusual molecular structure of a naturally produced, ocean-based compound that is giving new understanding of the function of mammalian nerve cells.
CAMBRIDGE, Mass. -- In a vivid illustration of natural selection at work, scientists at Harvard University have found that deer mice living in Nebraska's Sand Hills quickly evolved lighter coloration after glaciers deposited sand dunes atop what had been much darker soil. The work is described this week in the journal Science.
LAWRENCE, KAN. -- A new candidate gene for Specific Language Impairment has been identified by a research team directed by Mabel Rice at the University of Kansas, in collaboration with Shelley Smith, University of Nebraska Medical Center, and Javier Gayán of Neocodex, Seville, Spain.
Today's youngsters are buried under homework, which gobbles up free time that could be spent with family or friends. Parents, puzzled whether to help their children dig out from a pile of books or allow them to carry on alone, are frustrated by the take-home workload.

WASHINGTON, DC (August 11, 2009) - As flu season draws nearer along with the potential for resurgence in H1N1, leading infectious diseases doctors, hospital epidemiologists, and infection preventionists urge officials to base recommendations for the public and healthcare workers on scientific knowledge and frontline experience gained from the outbreak this summer.
Biologists have long known how adaptive evolution works. New mutations arise within a population and those that confer some benefits to the organism increase in frequency and eventually become fixed in the population.
Alexandria, VA -- Restraining the use of some patients' unaffected upper limb during the subacute phase following stroke does not appear to generate greater improvements in motor impairment and capacity than standard rehabilitation alone, according to a pilot study published in the June issue of Physical Therapy, the scientific journal of the American Physical Therapy Association (APTA)
CHICAGO -- The American Dietetic Association has released an updated position paper on food and water safety that reviews the current situation in this country, identifies new tools that can help decrease illness and encourages continued research, education and technological advances to keep the food and water supply safe.
