Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

Physicists at the National Institute of Standards and Technology (NIST) and partners have demonstrated an experimental, next-generation atomic clock--ticking at high "optical" frequencies--that is ...

Scientists have generated a real-time signal of an accurate time scale by combining an optical lattice clock and a hydrogen maser. The signal generated in this optical-microwave hybrid system ...
