| Paralyzed man uses thoughts alone to control robot arm, touch friend's hand, after seven years Posted: 08 Feb 2013 09:48 AM PST Researchers have described how an electrode array on top of the brain enabled a 30-year-old man to control the movement of a character on a computer screen in three dimensions with just his thoughts. It also enabled him to reach out with a robot arm to touch a friend's hand for the first time in the seven years since he was paralyzed.  |
| Posted: 08 Feb 2013 09:47 AM PST Scientists have demonstrated a new strategy for treating autoimmune disease that successfully blocked the development of rheumatoid arthritis in a mouse model. They say it holds promise for improved treatment of arthritis and other autoimmune disorders in people.  |
| 3-D printing on the micrometer scale Posted: 08 Feb 2013 07:59 AM PST Scientists have developed the world's fastest 3D printer of micro- and nanostructures. With this printer, smallest three-dimensional objects, often smaller than the diameter of a human hair, can be manufactured with minimum time consumption and maximum resolution. The printer is based on a novel laser lithography method.  |
| Putting our heads together: Canines may hold clues to human skull development Posted: 08 Feb 2013 07:53 AM PST Researchers have reviewed research on dog cranium development, suggest future research and how it may inform human skull development.  |
| Scientists find key to growth of 'bad' bacteria in inflammatory bowel disease Posted: 07 Feb 2013 02:21 PM PST Scientists have long puzzled over why "bad" bacteria such as E. coli can thrive in the guts of those with inflammatory bowel disease (IBD), causing serious diarrhea. Now researchers have discovered the answer -- one that may be the first step toward finding new and better treatments for IBD.  |
| Type 1 diabetes cured in dogs, study suggests Posted: 07 Feb 2013 08:44 AM PST Researchers have shown for the first time that it is possible to cure diabetes in large animals with a single session of gene therapy. After a single gene therapy session, the dogs recover their health and no longer show symptoms of the disease. In some cases, monitoring continued for over four years, with no recurrence of symptoms.  |
