Scientists propose a new atomic clock experiment that could reveal whether time itself follows the strange rules of quantum ...

The Bulletin of Atomic Scientists. is set to release a new setting for the Doomsday Clock on January 27. Perhaps we will be a bit safer from nuclear catastrophe, perhaps a bit closer. Somehow, though, ...

For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ytterbium to create a new type of atomic clock that is both highly precise and ...

Adelaide University researchers have successfully tested a new type of portable atomic clock at sea for the first time, using technology that could help power the next generation of navigation, ...

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.

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 ...
