People at genetic risk for Alzheimer's age mentally just like noncarriers
The Food and Drug Administration (FDA) has proposed an amended health claim that would communicate to consumers the value of foods high in calcium and vitamin D for reducing the risk of osteoporosis. The National Dairy Council (NDC) acknowledges and supports the body of scientific evidence that backs the proposed claim, which indicates that a lifestyle that includes a well-balanced diet with adequate calcium and vitamin D, and physical activity, helps reduce the risk of osteoporosis.
Scientists discover new, readily available source of stem cells
Scientists have discovered a new source of stems cells and have used them to create muscle, bone, fat, blood vessel, nerve and liver cells in the laboratory. The first report showing the isolation of broad potential stem cells from the amniotic fluid that surrounds developing embryos was published today in Nature Biotechnology. more
Rapid, low-cost DNA testing: Improving health and catching criminals
Professor Lewis Rothberg of the University of Rochester Chemistry Department received a NYSTAR grant in August 2006 to continue working on a recent discovery by Huixiang Li, a research associate in his group: how to rapidly test DNA to improve our health and make sure we're drinking clean water and eating uncontaminated food. In fact, his new method can be used to help forensics labs identify criminals, test ponds and pools before children swim in them, and identify harmful genetic sequences in medical research, to name only a few applications. Rothberg's innovative procedure quickly and inexpensively identifies genetic sequences in any sample of DNA. more
Getting to the bottom of memory
Phone numbers, the way to work, granny's birthday -- our brain with its finite number of nerve cells can store incredible amounts of information. At the bottom of memory lies a complex network of molecules. To understand how this network brings about one of the most remarkable capacities of our brain we need to identify its components and their interactions. Researchers from the European Molecular Biology Laboratory's (EMBL) Mouse Biology Unit in Monterotondo, Italy, and the Universidad Pablo de Olavide in Sevilla, Spain, now for the first time investigate the molecular basis of memory in living mice. The study, which appears in the current issue of Learning and Memory, identified a molecule that is crucially involved in learning and singled out the signaling pathway through which it affects memory. more
Glaucoma: Silently stealing sight from millions
As you read this sentence, you could be going blind and not know it. Silently, without symptoms, Glaucoma could be stealing your sight, and there is no cure.
New HIV test may predict drug resistance
Researchers at Duke University Medical Center have developed a highly sensitive test for identifying which drug-resistant strains of HIV are harbored in a patient's bloodstream. more
Fast-multiplying lawsuits can stymie medical science
Class-action lawsuits can significantly slow or halt science's ability to establish links between neurological illness and environmental factors produced by industry, a team of scientists and lawyers warns in the journal Neurology. more
