Summary

An understanding of why the universe is biased in favor of matter may have come a step closer with a burst of collisions in an accelerator called the Asymmetric B Factory. Based at the Stanford Linear Accelerator Center, the machine collides beams of electrons with positrons to make B mesons, which offer insights into a fundamental asymmetry between matter and antimatter. On 23 July, the two rings collided particles for the first time--a critical step in the long process of getting this novel facility up and running, which should be completed early next year.
