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 ...

To find out how clock accuracy is verified and which reference is used for comparison, we visited the Belarusian State ...

By Will Dunham WASHINGTON, Jan 27 (Reuters) - Atomic scientists set their "Doomsday Clock" on Tuesday closer than ever to midnight, citing aggressive behavior by nuclear powers Russia, China and the ...

The Bulletin of the Atomic Scientists announced on Jan. 27 that the hands of the Doomsday Clock moved forward four seconds and now sits at 85 seconds to midnight—the closest the symbolic clock has ...

Scientists have taken another giant step towards building the most precise clock ever imagined—one that could display not only the passage of time, but shifting rules of nature itself. An ...

Scientists cited artificial intelligence and how it’s used to supercharge disinformation as a new risk.

A Chicago-based group of scientists have once again warned the world is closer than ever to human-made destruction by moving ...

Scientists are close to creating a nuclear clock—an ultra-accurate clock that uses a low-energy transition in the nucleus of a thorium-229 atom to keep time. Electrical interference makes atomic ...

The field of optical atomic clocks, in combination with ultracold atoms, has transformed precision timekeeping and metrology. By utilising laser-cooled atoms confined in optical lattices, researchers ...

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 ...
