Main Question or Discussion Point

Nature may have handed scientists a new clue in a longstanding mystery: how matter beat out antimatter for dominance of the universe. Early data from twin experiments at the Tevatron, the world's reigning particle accelerator at Fermi National Accelerator Laboratory (Fermilab) in Batavia, Ill., suggest an unexpected cool person in the hugely successful standard model of particle physics.

The twist comes from odd behavior in a particle called the BS (pronounced "B-sub-S"), which flips back and forth between its matter and antimatter forms three trillions times per second.
