| Swiss scientist prove durability of quantum network Posted: 01 Dec 2011 05:02 PM PST Scientists and engineers have proven the worth of quantum cryptography in telecommunication networks by demonstrating its long-term effectiveness in a real-time network. Their international network, created in collaboration with ID Quantique and installed in the Geneva metropolitan area and crossing over to the site of CERN in France, ran for more than one-and-a-half years from the end of March 2009 to the beginning of January 2011. |
| China's demand for oil will equal US demand by 2040, study predicts Posted: 01 Dec 2011 10:25 AM PST Despite aggressive demand-management policies announced in recent years, China's oil use could easily reach levels comparable to today's US levels by 2040, according to a new energy study. |
| New switch could improve electronics Posted: 01 Dec 2011 09:54 AM PST Researchers have invented a new type of electronic switch that performs electronic logic functions within a single molecule. The incorporation of such single-molecule elements could enable smaller, faster, and more energy-efficient electronics. |
| Strange new 'species' of ultra-red galaxy discovered Posted: 01 Dec 2011 09:53 AM PST In the distant reaches of the universe, almost 13 billion light-years from Earth, a strange species of galaxy lay hidden. Cloaked in dust and dimmed by the intervening distance, even the Hubble Space Telescope couldn't spy it. It took the revealing power of NASA's Spitzer Space Telescope to uncover not one, but four remarkably red galaxies. And while astronomers can describe the members of this new "species," they can't explain what makes them so ruddy. |
| Bobsled runs -- fast and yet safe Posted: 01 Dec 2011 08:26 AM PST They should prove a challenge for the athletes, but not put them in danger: bobsled runs have to be simulated before being built. This simulation is based on the friction levels of the runners on the ice. Now it has become possible to measure these levels accurately. These results will help build the run for the 2014 Olympic Winter Games. |
