Quarks are the reason protons have a positive charge. Each quark has a fraction of an electric charge. A proton has two up ...

In just the first 259 days of data collection, KATRIN, a beta-decay-based detector in Germany, has set the smallest upper ...

A team of Rice University researchers reported the first direct observation of a surprising quantum phenomenon predicted over ...

Neutrinos are among the most enigmatic particles in the universe. They are omnipresent yet interact extremely rarely with ...

New data establish an upper limit of 0.45 eV/c2 (equivalent to 8 x 10-37 kilograms) for the neutrino mass. KATRIN measures neutrino mass in the laboratory using a model-independent method.
