Scientists are exploring a new type of optical atomic clock based on ytterbium-173 ions that could help define the future ...

This breakthrough in precision timing is about the size of your fingernail and only loses one second every 30,000 years.

Researchers at Wuhan University (WHU) in China have produced a commercially manufacturable atomic clock less than one-seventh ...

China has built a tiny, highly accurate atomic clock that could boost drones, missiles and satellite navigation, highlighting ...

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...

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 ...
