In nuclear beta decay an up quark ‘u’ in a proton converts into an up down quark ‘d,’ turning the proton into a neutron and emitting a positron and a neutrino. This work affects interpretation of beta ...

Particle and nuclear physics evokes evokes images of huge accelerators probing the extremes of matter. But in this round-up ...

Almost exactly 200 years ago, French physicist Sadi Carnot determined the maximum efficiency of heat engines. The Carnot ...

Researchers have combined theory and experiments to show that nuclear polarization does not limit studies of muonic atoms, clearing the way for new nuclear physics experiments. University of ...

The NPL has developed a miniaturised Atomic Fountain Clock that promises to make accurate timekeeping technology smaller.

The nucleus of an atom is now the modern version of sand flowing through an hourglass. Researchers have spent 15 years trying to increase accuracy in timekeeping. The U.S. standard currently relies on ...
