A new estimate of the ghostly particle’s maximum possible mass brings physicists a tad closer to understanding the universe.

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.

Now head of Cambridge University's nuclear physics lab, Rutherford oversaw ... was less than the atomic mass (average mass of the atom). For example, a helium atom has an atomic mass of 4, but ...
