| NASA studying ways to make 'tractor beams' a reality Posted: 03 Nov 2011 12:08 AM PDT Tractor beams -- the ability to trap and move objects using laser light -- are the stuff of science fiction, but a team of NASA scientists has won funding to study the concept for remotely capturing planetary or atmospheric particles and delivering them to a robotic rover or orbiting spacecraft for analysis.  |
| Astrobiologists discover 'sweet spots' for the formation of complex organic molecules in the galaxy Posted: 02 Nov 2011 04:00 PM PDT Scientists have compiled years of research to help locate areas in outer space that have extreme potential for complex organic molecule formation. The scientists searched for methanol, a key ingredient in the synthesis of organic molecules that could lead to life. Their results have implications for determining the origins of molecules that spark life in the cosmos.  |
| Physicists identify room temperature quantum bits in widely used semiconductor Posted: 02 Nov 2011 01:12 PM PDT Physicists may have earned silicon carbide –– a semiconductor commonly used by the electronics industry –– a role at the center of a new generation of information technologies designed to exploit quantum physics for tasks such as ultrafast computing and nanoscale sensing.  |
| Posted: 02 Nov 2011 01:11 PM PDT The discovery of 13 diffuse interstellar bands with the longest wavelengths to date could someday solve a 90-year-old mystery. Astronomers have now discovered new bands using data collected by the Gemini North telescope of stars in the center of the Milky Way. The new findings support recent ideas about the presence of large, possibly carbon-based organic molecules -— "carriers" —- hidden in interstellar dust clouds.  |
| Did life once exist below Red Planet's surface? NASA study of clays suggests watery Mars underground Posted: 02 Nov 2011 11:57 AM PDT A new NASA study suggests if life ever existed on Mars, the longest lasting habitats were most likely below the Red Planet's surface. A new interpretation of years of mineral-mapping data, from more than 350 sites on Mars examined by European and NASA orbiters, suggests Martian environments with abundant liquid water on the surface existed only during short episodes. These episodes occurred toward the end of a period of hundreds of millions of years during which warm water interacted with subsurface rocks. This has implications about whether life existed on Mars and how the Martian atmosphere has changed.  |
| Solar power could get boost from new light absorption design Posted: 02 Nov 2011 09:55 AM PDT Researchers have developed a new material that absorbs a wide range of wavelengths and could lead to more efficient and less expensive solar technology.  |
| Solar energy: Solar concentrator increases collection with less loss Posted: 02 Nov 2011 09:55 AM PDT Converting sunlight into electricity is not economically attractive because of the high cost of solar cells, but a recent, purely optical approach to improving luminescent solar concentrators may ease the problem, according to researchers.  |
