Electron bell probes 'house of mirrors.' (particle behavior in electric and magnetic fields)(Research News: Physics)

Article Abstract:

Researchers have developed a method to determine the source of the discrepancy between their predictions of how particle behavior in electric and magnetic fields and actual measurements of particle behavior. A 'superelectron' magnified the differences, which appear due to 'image charges' in nearby conductors.

Switching on a brilliant light

Article Abstract:

Use of the Advanced Photon Source (APS) is likely to advance materials sciences, solid-state physics and crystallography. The $811 million APS will have a radiation brilliance that is thousands of times greater than earlier synchrotrons.

Strings unknot problems in particle theory, black holes: physics

Article Abstract:

The 30-year question of string theory has produced several interesting and useful applications outside of physics, including helping unravel field theories, and the entropy of black holes.
