Physics world buzzing over faster-than-ever particles

Layman's article from the CanWest News Service
Fermilab physics lab in the U.S. has found a particle, far smaller than any atom, that switches itself back and forth between being a piece of matter and a piece of anti-matter 17 trillion times each second.

Fermilab's Press Release: for the more technically minded
BATAVIA, Illinois-Scientists of the DZero collider detector collaboration at the Department of Energy's Fermi National Accelerator Laboratory have announced that their data on the properties of a subatomic particle, the B_s meson ("B sub s"), suggest that the particle oscillates between matter and antimatter in one of nature's fastest rapid-fire processes-more than 17 trillion times per second. Their findings may affect the current view of matter-antimatter asymmetry, and might also offer a first glimpse of the contributions of new physics, such as supersymmetry, to particle physics.
