Function found for Alzheimer's protein (September 10, 2010) -- In people with Alzheimer's, the brain becomes riddled with clumps of protein, forming what are known as amyloid plaques. Now, new research appears to have found a function for the amyloid precursor protein (APP for short) that yields the prime ingredient in those plaques. ... > full story
Neurons: Faster than thought and able to multiply (September 10, 2010) -- Using computer simulations of brain-like networks, researchers from Germany and Japan have discovered why nerve cells transmit information through small electrical pulses. The process not only allows the brain to process information much faster than previously thought, but also single neurons are already able to multiply, opening the door to more complex forms of computing. ... > full story
A smart use for wisdom teeth: Making stem cells (September 10, 2010) -- A new study shows that wisdom teeth contain a valuable reservoir of tissue for the creation of stem cells; thus, everyone might be carrying around his or her own personal stem-cell repository should he or she ever need some. ... > full story
Perceived life-threat affects mental health, Swedish research finds finds (September 10, 2010) -- Feeling like your life is in danger during an accident or disaster can have long-term negative effects on health -- whether or not the threat to your life was real, according to research on the experiences and mental health of Stockholm residents who survived the 2004 Tsunami in the Indian Ocean. A few simple questions to survivors early on could help health care personnel identify those in need of extra support and follow-up, according to the researcher behind the thesis. ... > full story
New neurological deficit behind lazy eye identified (September 10, 2010) -- Researchers have identified a new neurological deficit behind amblyopia, or "lazy eye." Their findings shed additional light on how amblyopia results from disrupted links between the brain and normal visual processing. ... > full story
World's first transcontinental anesthesia: Researchers pioneer anesthetics via videoconferencing (September 10, 2010) -- Videoconferences may be known for putting people to sleep, but never like this. A team from McGill University's Department of Anesthesia achieved a world first on August 30, 2010, when they treated patients undergoing thyroid gland surgery in Italy remotely from Montreal, Canada. ... > full story
Researchers analyze impact of chemical BPA in dental sealants used in children (September 10, 2010) -- Researchers have found that bisphenol A (BPA) released from some plastic resins used in pediatric dentistry is detectable in the saliva after placement in children's mouths. ... > full story
Music on prescription could help treat emotional and physical pain (September 10, 2010) -- New research into how music conveys emotion could benefit the treatment of depression and the management of physical pain. Using an innovative combination of music psychology and leading-edge audio engineering the project is looking in more detail than ever before at how music conveys emotion. ... > full story
Diet-induced obesity accelerates leukemia, study shows (September 10, 2010) -- The first study to demonstrate that obesity can directly accelerate the progression of acute lymphoblastic leukemia has been conducted. ... > full story
Conditional small RNA molecules can kill cancer cells and leave healthy cells alone (September 10, 2010) -- In a recent study, researchers demonstrated that conditional small RNA molecules can effectively kill lab-grown human brain, prostate and bone cancer cells in a mutation-specific manner. The treatment separates the "diagnosis" and "treatment" aspects of chemotherapy, so a cell is killed if -- and only if -- it is diagnosed with a mutation. ... > full story
Use of medication for insomnia or anxiety may increase mortality risk, study suggests (September 10, 2010) -- Taking medications to treat insomnia and anxiety increases mortality risk by 36 percent, according to a new study. ... > full story
Effects of population aging have been exaggerated, new analysis suggests: More appropriate retirement ages? (September 10, 2010) -- Due to increasing life-spans and improving health many populations are "aging" more slowly than conventional measures indicate. Scientists have developed new measures of aging that take disability and longevity into account. Their results give policymakers new tools to better determine the economic cost of an aging population and set more appropriate retirement ages. ... > full story
