We choose to go to the muon Chemists Mohammad Goli and Shant Shahbazian posit two new light elements. They are muonium (Mu), in which an electron orbits a positively charged muon ( +), and muonic helium (He ), in which an electron orbits a 'nucleus' consisting of an alpha particle and a negative muon. |

Quantum timepiece ticks the right boxes In a remarkable feat of quantum horology, scientists in the US have created a clock that derives its timing mechanism from nothing more complicated than the mass of an atom. The new clock could prove to be a new way to make highly accurate measurements of atomic mass. |
