Progress using induced pluripotent stem cells to reverse blindness (June 18, 2011) -- Researchers have used cutting-edge stem cell technology to correct a genetic defect present in a rare blinding disorder, another step on a promising path that may one day lead to therapies to reverse blindness caused by common retinal diseases. ... > full story

More evidence vitamin D boosts immune response (June 18, 2011) -- Laboratory-grown gingival cells treated with vitamin D boosted their production of an endogenous antibiotic, and killed more bacteria than untreated cells, according to a new study. The research suggests that vitamin D can help protect the gums from bacterial infections that lead to gingivitis and periodontitis. Periodontitis affects up to 50 percent of the US population, is a major cause of tooth loss, and can also contribute to heart disease. Most Americans are deficient in vitamin D. ... > full story

New clues about protein linked to Parkinson's disease: Structural biologists measure energy difference between protein variants (June 18, 2011) -- Researchers have uncovered structural clues about the protein linked to Parkinson's disease, which ultimately could lead to finding a cure for the degenerative neurological disorder. ... > full story

'Ultrawideband' could be future of medical monitoring (June 18, 2011) -- New research has confirmed that an electronic technology called "ultrawideband" could hold part of the solution to an ambitious goal in the future of medicine -- health monitoring with sophisticated "body-area networks." Such networks would offer continuous, real-time health diagnosis to reduce the onset of degenerative diseases, save lives and cut health care costs. ... > full story

How many US deaths are caused by poverty and other social factors? About the same as deaths from heart attacks and stroke, study finds (June 18, 2011) -- In the first comprehensive analysis of the contribution of social factors to US mortality, researchers found that poverty, low levels of education, poor social support and other social factors contribute about as many deaths in the US as such familiar causes as heart attacks, strokes and lung cancer. ... > full story

Dawn of agriculture took toll on health (June 18, 2011) -- When populations around the globe started turning to agriculture around 10,000 years ago, regardless of their locations and type of crops, a similar trend occurred: the height and health of the people declined. The pattern holds up across standardized studies of whole skeletons in populations, say researchers in the first comprehensive, global review of the literature regarding stature and health during the agriculture transition. ... > full story

A better way to remember (June 18, 2011) -- Scientists and educators alike have long known that cramming is not an effective way to remember things. With their latest findings, researchers studying eye movement response in trained mice, have elucidated the neurological mechanism explaining why this is so. Their results suggest that protein synthesis in the cerebellum plays a key role in memory consolidation, shedding light on the fundamental neurological processes governing how we remember. ... > full story

American Cancer Society report finds continued progress in reducing cancer mortality (June 18, 2011) -- A steady reduction in overall cancer death rates translates to the avoidance of about 898,000 deaths from cancer between 1990 and 2007, according to the latest statistics from the American Cancer Society. However, progress has not benefited all segments of the population equally. ... > full story

The way you relate to your partner can affect your long-term mental and physical health, study shows (June 18, 2011) -- The potentially lasting implications of day-to-day couple conflict on physical and mental well-being are revealed in a new study. ... > full story

Tapeworm drug inhibits colon cancer metastasis (June 17, 2011) -- A compound that for about 60 years has been used as a drug against tapeworm infection is also apparently effective against colon cancer metastasis, as studies using mice have shown. The compound silences a gene that triggers the formation of metastases in colon cancer. Researchers in Germany made this discovery in collaboration with researchers in the U.S. Plans are already underway to conduct a clinical trial. ... > full story

Size matters -- in virulent fungal spores -- and suggests ways to stop a killer (June 17, 2011) -- Scientists have found that larger fungal spores can be more lethal. Their findings about two different spore sizes of the fungus Mucor circinelloides, a pathogen that kills half or more of its victims, could help to develop new treatments and fight other types of fungal infections. Mucor infection is in the news as an environmental fungus contracted by people who had trauma in the wake of tornadoes in Joplin, Mo. ... > full story

Surgeons perform first prosthetic bypass graft with patient's stem cells at point-of-care (June 17, 2011) -- The first three patients to undergo an investigational surgical procedure for peripheral vascular disease that involves the patient's own stem cells continue to do well, say doctors . The "TGI-PVG IDE" clinical trial initiated at the University of Louisville involves using a patient's own stem cells to line artificial bypass grafts to better the chances at saving the limbs of patients with peripheral artery disease. ... > full story
