  Dramatic differences found in matter and antimatter (Aug 3)
   The international BaBar collaboration working at the Stanford Linear
   Accelerator Center (SLAC) in the US has found the most dramatic evidence
   to date for the difference between matter and antimatter. The experiment
   has found that the number of decays observed for a class of particles
   known as B mesons is 13% higher than for their antiparticle equivalents
   -- anti-B mesons (arXiv.org/abs/hep-ex/0407057). The results could help
   explain why the universe is dominated by matter, rather than
   anti-matter, or why it does not contain equal amounts of both.
