Researchers at Mount Sinai School of Medicine set out to address a question that has been challenging scientists for years: How do dietary restriction -- and the reverse, overconsumption -- produce protective effects against aging and disease?
College Park, Md -- As rates of obesity, diabetes, and related disorders have reached epidemic proportions in the US in recent years, scientists are working from many angles to pinpoint the causes
With technology similar to that used by physicians to perform magnetic resonance imaging (MRI) scans, researchers from six institutions -- including the National Institute of Standards and Technology (NIST) -- working at the Hollings Marine Laboratory (HML) in Charleston, S.C., are studying the metabolic activity of a pathogen shown to cause coral bleaching, a serious threat to undersea reef ec
Jerusalem, Sept. 14, 2009 -- A new understanding of how anesthesia and anesthesia-like states are controlled in the brain opens the door to possible new future treatments of various states of loss of consciousness, such as reversible coma, according to Hebrew University of Jerusalem scientists.
SEATTLE -- Scientific dogma has long asserted that females are born with their entire lifetime's supply of eggs, and once they're gone, they're gone. New findings by researchers at Fred Hutchinson Cancer Research Center, published online Aug.
Scientists at the Johns Hopkins Kimmel Cancer Center have discovered how two cancer-promoting genes enhance a tumor's capacity to grow and survive under conditions where normal cells die. The knowledge, they say, may offer new treatments that starve cancer cells of a key nutrient - sugar.
DALLAS -- Aug. 3, 2009 -- Infectious-disease specialists at UT Southwestern Medical Center have demonstrated that a cannibalistic process in cells plays a key role in limiting Salmonella infection.
New imaging technology provides insight into abnormalities in the brain circuitry of patients with anorexia nervosa (commonly known as anorexia) that may contribute to the puzzling symptoms found in people with the eating disorder.
Wolves have caused elk in the Greater Yellowstone Ecosystem to change their behavior and foraging habits so much so that herds are having fewer calves, mainly due to changes in their nutrition, according to a study published this week by Montana State University researchers.
Mycobacterium tuberculosis is arguably the world's most successful infectious agent because it knows how to avoid elimination by slowing its own growth to a crawl. Now, a report in the July 10 issue of the journal Cell, a Cell Press publication, offers new insight into the bugs' talent for meager living.
A drug derived from the hydrangea root, used for centuries in traditional Chinese medicine, shows promise in treating autoimmune disorders, report researchers from the Program in Cellular and Molecular Medicine and the Immune Disease Institute at Children's Hospital Boston (PCMM/IDI), along with the Harvard School of Dental Medicine.
Warm summers are dramatically reducing populations of daddy long legs, which in turn is having a severe impact on the bird populations which rely on them for food.
New research by a team of UK scientists spells out for the first time how climate change may affect upland bird species like the golden plover - perhaps pushing it towards local extinction by the end of the century.
In times of starvation, cells tighten their belts: they start to digest their own proteins and cellular organs. The process - known as autophagy - takes place in special organelles called autophagosomes. It is a strategy that simple yeast cells have developed as a means of survival when times get tough, and in the course of evolution, it has become a kind of self-cleaning process.
Research by kinesiology investigator Dustin Hittel, PhD, has proven that muscle in extremely obese individuals produces large amounts of a protein called myostatin, which normally inhibits muscle growth?suggesting that for Type 2 diabetics, and the very obese, the task of getting healthy may be more difficult than initially thought.
Only two years after launching an ambitious effort to save endangered crop species, the Global Crop Diversity Trust announced today it is on track to save from extinction 100,000 different varieties of food crops from 46 countries.
