| New spin on computing: Toward a new breed of computers that can process data using less power Posted: 21 Jun 2011 02:35 PM PDT Harnessing the magnetic moment, or spin, of electrons rather than their electric charge, physicists have achieved a breakthrough toward the development of a new breed of computing devices that can process data using less power.  |
| Acrobatics for anyons: New test for elusive fundamental particle proposed Posted: 21 Jun 2011 10:13 AM PDT Anyons are hypothetical particles that have been postulated to represent a third class of fundamental particles alongside the known bosons and fermions. Physicists in Germany have now proposed a novel experimental design that should make it possible to create and detect them for the first time.  |
| Self-cleaning anodes could facilitate cost-effective coal-powered fuel cells Posted: 21 Jun 2011 08:41 AM PDT Using barium oxide nanoparticles, researchers have developed a self-cleaning technique that could allow solid oxide fuel cells to be powered directly by coal gas at operating temperatures as low as 750 degrees Celsius. The technique could provide an alternative for generating electricity from the nation's vast coal reserves.  |
| Quantum leap: Magnetic properties of a single proton directly observed for the first time Posted: 21 Jun 2011 07:13 AM PDT An important milestone in the direct measurement of the magnetic moment of the proton and its anti-particle has been achieved. Researchers have observed spin quantum-jumps with a single trapped proton for the first time. The result is a pioneering step forward in the endeavor to directly measure the magnetic properties of the proton with high precision.  |
| Astronomers discover that galaxies are either asleep or awake Posted: 21 Jun 2011 07:11 AM PDT Astronomers have probed into the distant universe and discovered that galaxies display one of two distinct behaviors: they are either awake or asleep, actively forming stars or are not forming any new stars at all. A new survey shows that even very young galaxies as far away as 12 billion light years display one of these two states, meaning galaxies have behaved this way for more than 85 percent of the history of the universe.  |
