The National Institute of Standards and Technology recently warned that an atomic clock device installed at its Boulder campus had failed due to a prolonged power ...

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with ...

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.

An NIST physicist holds the newly modified ion trap for the aluminum ion clock. By modifying the trap, the aluminum ion and its magnesium ion partner could 'tick' unperturbed. Optical atomic clocks ...

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 ...

Atomic clocks have long been the gold standard for measuring time and frequency. Among them, optical clocks—using atoms like strontium or aluminum—have reached staggering levels of accuracy, with ...

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 ...

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 ...

As if timekeeping in the U.S. wasn’t already pretty accurate, the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) just declared a new atomic clock, the NIST-F2, to ...

In a first, researchers from the U.S. and Germany excite Thorium-229 in opaque material, advancing optical nuclear clocks.

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. The ongoing race to create the next generation of hyperaccurate ...
