The advantage of a radio-controlled clock that receives the time signal from WWVB is that you never have to set it again. Whether it’s a little digital job on your desk, or some big analog wall clock ...

Keeping time is easy, keeping precise time is hard, but a new type of clock based on atomic nuclei has pushed time-keeping precision to new levels.

World's first thorium-229 nuclear clock shows potential for ultra-precise timekeeping and fundamental physics tests.

Atomic clocks are a class of clocks that leverage resonance frequencies of atoms to keep time with high precision. While these clocks have become increasingly advanced and accurate over the years, ...

Yuan-Yu Jau is on a quest to build the world's smallest atomic clock, a device that measures time with extreme accuracy. If successful, he and his team at Sandia will have made one smaller than a ...

For decades, scientists have tried to build a device even more precise than an atomic clock, which keeps time using electrons, the negatively charged particles that whiz around in an atom. Now, two ...

Atomic clocks have been around for nearly 80 years, but their successors—nuclear clocks—are ready to take the stage. Two independent studies, both uploaded as preprints, report reliable timekeeping ...

Researchers from the University of Amsterdam and the University of New South Wales have answered a question that has been ...

The device, which traps thousands of atoms to keep time, is "pushing the boundaries of what's possible with timekeeping." Reading time 2 minutes New clock just dropped, but it’ll only drop a second ...

Researchers demonstrated a new optical atomic clock that uses a single laser and doesn't require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks without ...

For decades, physicists have pursued a goal that sounds nearly impossible: to build a clock that keeps time using an atom's nucleus rather than the electrons orbiting it. "Having worked in this field ...

An atomic clock that could pave the way for autonomous deep space travel was successfully activated last week and is ready to begin its year-long tech demo, the mission team confirmed on Friday, Aug.
