Acupuncture can prevent radiation-induced chronic dry mouth, study finds (November 11, 2011) -- When given alongside radiation therapy for head and neck cancer, acupuncture has shown for the first time to reduce the debilitating side effect of xerostomia, according to new research. ... > full story

Kawasaki disease linked to wind currents: First evidence that long-range wind transport of an infectious agent might result in human disease (November 11, 2011) -- Kawasaki Disease (KD) is a severe childhood disease that many parents, even some doctors, mistake for an inconsequential viral infection. In fact, if not diagnosed or treated in time, it can lead to irreversible heart damage. After 50 years of research, including genetic studies, scientists have been unable to pinpoint the cause of the disease. Now, surprising findings suggest that KD cases are linked to large-scale wind currents that track from Asia to Japan and also traverse the North Pacific. ... > full story

Parkinsonian worms may hold the key to identifying drugs for Parkinson's disease (November 11, 2011) -- Researchers have devised a simple test, using dopamine-deficient worms, for identifying drugs that may help people with Parkinson's disease. ... > full story

Dead of winter is tough on arthritis sufferers (November 11, 2011) -- As cold winter weather sets in and daylight hours dwindle, many older Chicagoans with arthritis tend to sit idle, missing out on the daily dose of physical activity they need to improve their health, according to a new study. ... > full story

Woodsmoke from cooking fires linked to pneumonia, cognitive impacts (November 11, 2011) -- Researchers have found a dramatic one-third reduction in severe pneumonia diagnoses among children in homes with smoke-reducing chimneys on their cookstoves. Reducing wood smoke could have a major impact on the burden of pneumonia, the leading cause of child mortality in the world, the researchers said. A separate pilot study also found a link between prenatal maternal exposure to woodsmoke and poorer performance in markers for IQ at ages six and seven. ... > full story

Attention and awareness uncoupled: Brain imaging experiments uncouple two apparently intimately connected mental processes (November 11, 2011) -- In everyday life, attention and awareness appear tightly interwoven. Attending to the scissors on the right side of your desk, you become aware of their attributes, for example the red handles. Vice versa, the red handles could attract your attention to the scissors. However, a number of behavioural observations have recently led scientists to postulate that attention and awareness are fundamentally different processes and not necessarily connected. A new study provides the first experimental evidence that the primary visual cortex, the entrance stage to cortical visual processing, is modulated only by attention and not by awareness. ... > full story
