Unraveling the Secrets of an Atomic Switch 24 August 2006 |
|
|
Scientists at the Commerce Department’s National Institute of Standards and Technology (NIST) have used a beam of electrons to move a single atom in a small molecule back and forth between two positions on a crystal surface, a significant step toward learning how to build an “atomic switch” that turns electrical signals on and off in nanoscale devices |

Particle physicists measure matter-antimatter flip July 2006 |
|
|
A subatomic particle called the strange neutral B-meson has been found to spontaneously flip into its own antiparticle and back again three trillion times per second, explains Joseph Kroll. |

New Technique for Manipulation of Light Beams Demonstrated 8 August 2006 |
|
|
It may be surprising that a laser beam, when shot to the moon and returned by one of the mirrors the Apollo astronauts left behind, is a couple of miles in diameter at the end of its half-million-mile round trip. This spread is mostly due to atmospheric distortions, but it nonetheless underscores the problems posed to those who wish to keep laser beams from diverging or focusing to a point as light travels through a medium. |
