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.

Now, physicists at the US National Institute of Standards and Technology (NIST) and the University of Delaware have developed the most accurate and precise atomic clock yet, using a 'web' of light to ...

Accuracy may come at a cost. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. What’s the price of an accurate clock? Entropy, a new study has ...

An experimental atomic clock based on a single mercury atom is now at least five times more precise than the national standard clock based on a “fountain” of cesium atoms, according to a paper by ...

Here’s what you’ll learn when you read this story: Timekeeping has evolved greatly during humanity’s short time on Earth, and that legacy of metrological innovation is far from over. A new study from ...

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 ...

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 ...
