| Woman with quadriplegia feeds herself chocolate using mind-controlled robot arm Posted: 17 Dec 2012 12:09 AM PST Reaching out to "high five" someone, grasping and moving objects of different shapes and sizes, feeding herself dark chocolate. For Jan Scheuermann and a team of researchers, accomplishing these seemingly ordinary tasks demonstrated for the first time that a person with longstanding quadriplegia can maneuver a mind-controlled, human-like robot arm in seven dimensions (7D) to consistently perform many of the natural and complex motions of everyday life.  |
| Scientists discover evidence of giant panda's population history and local adaptation Posted: 16 Dec 2012 10:25 AM PST A research team has successfully reconstructed a continuous population history of the giant panda from its origin to the present.  |
| Ordinary heart cells become 'biological pacemakers' with injection of single gene Posted: 16 Dec 2012 10:25 AM PST Researchers have reprogrammed ordinary heart cells to become exact replicas of highly specialized pacemaker cells by injecting a single gene -- a major step forward in the decade-long search for a biological therapy to correct erratic and failing heartbeats.  |
| 'Missing' polar weather systems could impact climate predictions Posted: 16 Dec 2012 10:25 AM PST Intense but small-scale polar storms could make a big difference to climate predictions, according to new research. Difficult-to-forecast polar mesoscale storms occur frequently over the polar seas; however, they are missing in most climate models. New research shows that their inclusion could paint a different picture of climate change in years to come.  |
