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 ...

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 ...

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.

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 ...

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 ...

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 ...

If, like me, you can't go a day without making sure your watch is synced to the second, you'll be delighted to learn that a new atomic clock has broken the record with an accuracy of 5.5 x 10⁻¹⁹ – ...

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 ...

Jun Ye spends most of his days in the basement of a research building at the University of Colorado, Boulder. There, spread across several stainless steel tables, is a nearly half-ton machine that ...

The most accurate timekeepers in the world just got a new use. It turns out they can double up as simulators to help us better understand the deepest mysteries of the quantum world. Many problems in ...

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 ...
