Mitochondrial DNA Mutations Play Significant Role In Prostate Cancer Mutations in mitochondrial DNA (mtDNA) play an important role in the development of prostate cancer, according to research by scientists at Emory University School of Medicine and the University of California, Irvine. Conceptualizing A Cyborg: New Ideas On Developing Thought-Controlled A Investigators at the University of Pennsylvania School of Medicine describe the basis for developing a biological interface that could link a patient's nervous system to a thought-driven artificial limb. Their conceptual framework brings together years of spinal-cord injury research. New Target Found To Fight, Treat Parkinson's Neuroscientists from the University at Buffalo have described for the first time how rotenone, an environmental toxin linked specifically to Parkinson's disease, selectively destroys the neurons that produce dopamine, the neurotransmitter critical to body movement and muscle control. Ibuprofen Can Slow Lung Disease In Children With Cystic Fibrosis, Stud The results of a clinical trial indicates that, when used as part of routine therapy, high-dose ibuprofen is safe and effective in slowing down lung disease in children with cystic fibrosis (CF). Long-sought Maya City -- Site Q -- found in Guatemala A team of scientists including Marcello Canuto, assistant professor of anthropology at Yale, has found incontrovertible proof of Site Q, a long-speculated Mayan city, during a mission to the northwest Peten region of Guatemala. Ozone Pollution: Often, But Not Always, Caused By Humans Depending on its altitude, ozone can be either friend or foe. Ozone moves through our skies naturally, and so-called 'ozone intrusions'can be monitored using a relatively simple radar instrument. Although low-level ozone, ozone pollution, is frequently caused by humans, sudden natural changes in the altitude of the upper boundary of the troposphere can also play a role in the distribution of ozone. Study Looks At Benefits Of Two Cochlear Implants In Deaf Children Nature has outfitted us with a pair of ears for good reason: having two ears enhances hearing. University of Wisconsin-Madison scientists are now examining whether this is also true for the growing numbers of deaf children who've received not one, but two, cochlear implants to help them hear. Floating Effective For Stress And Pain, Research Suggests Relaxation in large, sound- and light-proof tanks with high-salt water -- floating -- is an effective way to alleviate long-term stress-related pain. Sleep was improved, patients felt more optimistic, and the content of the vitalizing hormone prolactin increased. Anxiety, stress, depression, and perception of pain declined. MIDI Ironing Boards, Theremin Crutches Squeal at Handmade Music Event Tweakers make a racket when they unveil electro-musical oddities at Brooklyn gathering. Seepage Of Drugs From Hog Farms Not An Environmental Problem, Study Su Environmental activists have long criticized pharmaceutical use by hog farmers and veterinarians in treating swine disease, saying pharmaceuticals are being overused and errantly contaminating the environment. But new research suggests that environmental contamination from antibiotics does not pose appreciable risks to soil and aquatic organisms. The scientists have determined that pharmaceuticals represent negligible environmental risk if used as instructed.
