NASA launches new CARBON OBSERVATORY
A rocket carrying a NASA satellite launched Wednesday on a mission to track atmospheric carbon dioxide, the chief culprit behind global warming. The Delta 2 rocket blasted off from California at 2:56 a.m. and released the Orbiting Carbon Observatory-2 satellite in low-Earth orbit 56 minutes later. Initial checks showed the spacecraft was healthy and two-way communications were established, officials said. NASA tried in 2009 to launch a satellite to study carbon dioxide, but it plunged into the ocean off Antarctica after a hardware failure with the Taurus XL rocket. NASA has spent years and millions of dollars to build a near-identical twin.
Walking may help for Parkinson's
In yet another endorsement for walking, researchers said Wednesday that people with mild to moderate Parkinson's disease may improve their motor function, mood, fatigue levels and more with regular aerobic walks. "The results of our study suggest that walking may provide a safe and easily accessible way of improving the symptoms of Parkinson's disease and improve quality of life," said the lead author. Dr. Ergun Uc of the University of Iowa and the Veterans Affairs Medical Center in Iowa City and colleagues published their findings in the journal Neurology. Federal guidelines recommend 150 minutes a week of moderate aerobic activity for adults 18 to 65.
