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

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

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 ...

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 ...

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 ...

Atomic clocks will only see a loss of 1 second in accuracy over a period of 10 million years. They are used in multiple ways, including the GPS in your car. Now researchers have found a way to bypass ...

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 ...

For centuries, time was tied to Earth’s rotation, with a second defined as a fraction of a full day. But inconsistencies in the planet’s spin made that system unreliable for scientific use. Since 1967 ...

A sudden atomic clock failure on March 13, 2026, disabled a key NavIC satellite within minutes, prompting concerns over India ...
