Physicists have measured and controlled seemingly forbidden collisions between neutral strontium atoms--a class of antisocial atoms known as fermions that are not supposed to collide when in identical energy states. The advance makes possible a significant boost in the accuracy of atomic clocks based on hundreds or thousands of neutral atoms.
