Advanced Technologies Reveal New Knowledge About The Lives And Deaths Using genetics, Navy sonar, deep-sea submersibles, and toxicology, scientists are peering into the lives of whales -- past and present -- in ways never before possible. What Makes The Brain Tick, Tick, Tick: Researchers Gaining New Insight The brain is a "time machine,"assert Duke neuroscientists Catalin Buhusi and Warren Meck. And understanding how the brain tracks time is essential to understanding all its functions. The brain's internal clocks coordinate a vast array of activities from communicating, to orchestrating movement, to getting food, they said. The Children's Television Rules This document explains the Children's Television Act of 1990 (CTA), which "established a specific programming obligation for each television licensee to serve the 'educational and informational needs' of children,"and the changes to the act effective January 2006. Discusses core programming and the "three hour rule,"commercial limits (including display of website addresses), penalties, and related material. From the legal department of the National Association of Broadcasters (NAB). Brain Wave Changes In Adolescence Signal Reorganization Of The Brain Brain wave changes in adolescence are related to age, but not sexual maturation, occur earlier in girls than boys and may be associated with one of the brain's major reorganization projects: synaptic pruning, a new study finds. During adolescence, the brain reorganizes and eliminates many synaptic connections, making the brain's information processing more efficient and powerful while consuming less energy. Little Evidence Behind Bronchodilator Therapy For Cystic Fibrosis Little evidence exists to support the widespread use of bronchodilators to treat children and adults with cystic fibrosis, according to a new systematic review of published research. Passive Smoke In Workplace Increases Lung Cancer Risk, Report Says An analysis of nearly two dozen studies confirms the association between passive smoke in the workplace and an increased risk of lung cancer, according to a report in the American Journal of Public Health. Brain Injury Association of Washington Publications and resources from this Washington state organization that provides education, information, and advocacy for survivors of brain injuries and their families. Features a brain injury fact sheet, prevention tips, events calendar, a list of support groups in the state, links to other resources (including rehabilitation centers in Washington), and related material. Cryoablation Treatment Helps Diminish Pain Of Bone Cancer Pain from cancer that has spread to the bone can be effectively diminished with a new treatment that freezes the cancerous areas, Mayo Clinic researchers reported today at the 30th Annual Scientific Meeting of the Society of Interventional Radiology in New Orleans. Adventures in the Past: Discovering the Public Lands' Archaeological. This site provides links to lesson plans and articles for teaching and learning about history, archeology, and paleontology on public land in the western U.S. Also features an interactive map with links to material about vacation opportunities at BLM-administered sites, and selected research publications on topics such as Native Americans, the Oregon Trail, and the Iditarod. From the U.S. Bureau of Land Management (BLM). Paralyzed People Using Computers, Amputees Controlling Bionic Limbs, W Experimental devices that read brain signals have helped paralyzed people use computers and may let amputees control bionic limbs. But existing devices use tiny electrodes that poke into the brain. A new study shows that brain signals controlling arm movements can be detected accurately using new microelectrodes that sit on the brain but don't penetrate it.
