The way the world measures time could be heading for a rare and significant overhaul. Advances in precision technology are ...

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

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

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

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 ...

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

Physicists are getting closer to creating a long-sought ‘nuclear clock’. This device would keep time by measuring energy ...

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 ...

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world measures one second in the near future. Researchers from Adelaide University ...

To find out how clock accuracy is verified and which reference is used for comparison, we visited the Belarusian State Institute of Metrology (BelGIM), where most of the national standards are kept.

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years’ time, they could ...
