Scientists discover how matter kicked antimatter's ass in the ancient universe

Science FTW:

Using the Tevatron Collider in Batavia, Illinois, scientists discovered that B mesons, a type of subatomic particle, do not decay into equal amounts of matter and antimatter, as previously thought. Rather, they produce about one percent more muons (a heavier counterpart of electrons) than antimuons, resulting in a net gain of positive matter.

Next question: is the B meson a mutation that allowed this universe to survive where others did not?
