LIFETIME ACHIEVEMENT To make a new measurement of the neutron’s lifetime, physicists confined neutrons within a chamber and counted the number that remained using an apparatus (shown) located at Los Alamos National Laboratory in New Mexico.

A genie in a bottle might grant you a wish, but neutrons trapped in a bottle aren’t so accommodating.

Outside of an atomic nucleus, the neutral particles eventually decay into other particles. But scientists aren’t sure exactly how long neutrons stick around for before their demise:
