ALPHA Stores Antimatter Atoms Over a Quarter of an Hour – and Still Counting. News Release An artistic representation of the ALPHA neutral antimatter trap, suggesting the nature of the ALPHA apparatus as a container for antihydrogen.

The ALPHA Collaboration, an international team of scientists working at CERN in Geneva, Switzerland, has reported storing a total of 309 atoms of antihydrogen, some for up to 1,000 seconds (almost 17 minutes), with an indication of much longer storage time as well. ALPHA announced in November, 2010, that they had succeeded in storing antimatter atoms for the first time ever, having captured 38 atoms of antihydrogen and storing each for a sixth of a second.
Scientists at the U.S. Says Fajans, “Perhaps the most important aspect of this result is that after just one second the antihydrogen atoms had surely already decayed to ground state. “So far, the only way we know whether we’ve caught an anti-atom is to turn off the magnet,” says Fajans.

News Release Imagine charging your phone as you walk, thanks to a paper-thin generator embedded in the sole of your shoe. This futuristic scenario is now a little closer to reality. Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a way to generate power using harmless viruses that convert mechanical energy into electricity. The scientists tested their approach by creating a generator that produces enough current to operate a small liquid-crystal display.
It works by tapping a finger on a postage stamp-sized electrode coated with specially engineered viruses. The viruses convert the force of the tap into an electric charge. Their generator is the first to produce electricity by harnessing the piezoelectric properties of a biological material. The milestone could lead to tiny devices that harvest electrical energy from the vibrations of everyday tasks such as shutting a door or climbing stairs. Additional information:
