Scientists at the High Energy Accellerator Research Organization in
Tsukuba have discovered a new subatomic particle that can't be explained
under current theories.  It has about the same mass as a helium atom,
and is known as X(3872) or the "mystery meson."  Its existance has been
confirmed at the Fermi National Accelerator Laboratory.
