| Asteroid lutetia: Primitive body from solar system's planet-forming period Posted: 28 Oct 2011 11:40 AM PDT The European Space Agency's Rosetta spacecraft has revealed asteroid Lutetia to be a primitive body, left over as the planets were forming in our Solar System. Results from Rosetta's fleeting flyby also suggest that this mini-world tried to grow a metal heart.  |
| New hybrid technology could bring 'quantum information systems' Posted: 28 Oct 2011 11:25 AM PDT The merging of two technologies under development - plasmonics and nanophotonics - is promising the emergence of new "quantum information systems" far more powerful than today's computers.  |
| Posted: 28 Oct 2011 07:50 AM PDT A team of researchers has found one of the most effective catalysts ever discovered for splitting oxygen atoms from water molecules -- a key reaction for advanced energy-storage systems, including electrolyzers, to produce hydrogen fuel and rechargeable batteries. This new catalyst liberates oxygen at more than 10 times the rate of the best previously known catalyst of its type.  |
| New method in spectral analysis: Measuring the distance of processes Posted: 28 Oct 2011 07:32 AM PDT A milestone in the description of complex processes -- for example the ups and downs of share prices -- has been reached by mathematicians. Researchers have developed a new method in spectral analysis, which allows a classical mathematical model assumption, so-called stationarity, to be precisely measured and determined for the first time. The approach also makes it possible to construct statistical tests that are considerably better and more accurate than previous methods.  |
| Planets smashed into dust near supermassive black holes Posted: 28 Oct 2011 05:20 AM PDT Fat doughnut-shaped dust shrouds that obscure about half of supermassive black holes could be the result of high speed crashes between planets and asteroids, according to a new theory from an international team of astronomers.  |
| Printed protection: Low-cost paper-based wireless sensor could help detect explosive devices Posted: 27 Oct 2011 10:25 AM PDT Researchers have developed a prototype wireless sensor capable of detecting trace amounts of a key ingredient found in many explosives. The device, which employs carbon nanotubes, is printed on paper or paper-like material.  |
