Researchers in Dr. Young’s group have successfully measured the lifetime of the neutron in a magnetic trap. Their results were published recently in Science. This unique method allowed them to store neutrons to measure their lifetime while removing any complications from them interacting with the walls of the trap. The necessary corrections using this method are thus smaller than the uncertainties in the measurement, in contrast to previous trap measurements of the neutron lifetime.
