A clock built by a team led by researchers at the National Institute of Standards and Technology (NIST) has been estimated to be 41 percent more accurate than the previous timekeeping record holder.

Improvements in clocks are setting the stage for a redefinition of the second. This is an Inside Science story. (Inside Science) -- Earlier this year, in a nondescript lab at the National Institute of ...

There's a new record holder for the most accurate clock in the world. Researchers at the National Institute of Standards and Technology (NIST) have improved their atomic clock based on a trapped ...

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 ...

The most accurate clock in space launches within days and will begin building a highly synchronised network out of the best clocks on Earth. But the project, decades in preparation, will only operate ...

Researchers in Boulder built a new clock that is more precise and accurate than any clock in the world. The discovery has implications for exploring fundamental physics questions, propelling new ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...

An extremely cold gas of strontium atoms is trapped in a web of light known as an optical lattice. The atoms are held in an ultrahigh-vacuum environment, which means there is almost no air or other ...

With shrinking process nodes and increasing operating frequencies, designers face the challenges of managing noise caused by signal crosstalk and dynamic voltage drop to meet their timing requirements ...

This short video, made at the UK’s National Physical Laboratory, proudly explains the science behind the world’s first accurate atomic clock. It was designed by Louis Essen and built at the National ...
