| Lessons from cockroaches could inform robotics Posted: 22 Feb 2013 11:32 AM PST Running cockroaches start to recover from being shoved sideways before their dawdling nervous system kicks in to tell their legs what to do, researchers have found. These new insights on how biological systems stabilize could one day help engineers design steadier robots and improve doctors' understanding of human gait abnormalities.  |
| Watching molecules grow into microtubes Posted: 22 Feb 2013 09:07 AM PST Sometimes the best discoveries come by accident. A team of researchers unexpectedly found the mechanism by which tiny single molecules spontaneously grow into centimeter-long microtubes by leaving a dish for a different experiment in the refrigerator.  |
| Posted: 22 Feb 2013 07:26 AM PST Tiny molecular tweezers have a remarkable impact on bustling proteins: Scientists have found that molecular tweezers can be used to regulate protein-protein interactions by selectively trapping certain residues of the protein -- and stick like a clothespin.  |
| Light from silicon nanocrystal LEDs: Scientists develop multicolor LEDs without heavy metals Posted: 22 Feb 2013 04:57 AM PST Silicon nanocrystals have a size of a few nanometers and possess a high luminous potential. Scientists have now succeeded in manufacturing silicon-based light-emitting diodes (SiLEDs). They are free of heavy metals and can emit light in various colors.  |
| World premiere of muscle and nerve controlled arm prosthesis Posted: 22 Feb 2013 04:57 AM PST Electrodes have been permanently implanted in nerves and muscles of an amputee to directly control an arm prosthesis, for the first time. The result allows natural control of an advanced robotic prosthesis, similarly to the motions of a natural limb.  |
| Posted: 21 Feb 2013 08:57 AM PST Tiny particles of titanium dioxide are found as key ingredients in wall paints, sunscreens, and toothpaste; they act as reflectors of light or as abrasives. However with decreasing particle size and a corresponding change in their surface-to-volume ratio, their properties change so that crystalline titanium dioxide nanoparticles acquire catalytic ability: Activated by the UV component in sunlight, they break down toxins or catalyze other relevant reactions. Now, chemists have developed a synthesis to produce nanoparticles at room temperature in a polymer network.  |
