| 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.  |
| Researchers explore quantum entanglement Posted: 08 Feb 2013 08:02 AM PST Researchers propose a way in which "spooky action at a distance" can be shown experimentally.  |
| 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.  |
| Implants make light work of fixing broken bones Posted: 08 Feb 2013 07:58 AM PST Artificial bone, created using stem cells and a new lightweight plastic, could soon be used to heal shattered limbs. The use of bone stem cells combined with a degradable rigid material that inserts into broken bones encourages real bone to re-grow. Researchers have developed the material with a honeycomb scaffold structure that allows blood to flow through it, enabling stem cells from the patient's bone marrow to attach to the material and grow new bone. Over time, the plastic slowly degrades as the implant is replaced by newly grown bone.  |
| Innovative water purification tablet for developing world Posted: 08 Feb 2013 07:53 AM PST Scientists have invented a simple ceramic water purification tablet. Called MadiDrop, the tablet is impregnated with silver or copper nanoparticles. It can repeatedly disinfect water for up to six months simply by resting in a vessel where water is poured.  |
| Satellite navigation system avoids traffic jams Posted: 07 Feb 2013 08:49 AM PST Endlessly frustrated by congested roads, computer scientists have developed a satellite navigation system, GeoTNavi, which hooks into historical traffic data and current vehicle movements to find the shortest commute and avoid the traffic jams.  |
