Nuclear clocks are a technology researchers have been working toward for decades. New research in theoretical physics brings them closer to reality.

A recent study published in Nature details a significant advancement in the creation of practical nuclear clocks.

Scientists have taken another giant step towards building the most precise clock ever imagined—one that could display not only the passage of time, but shifting rules of nature itself. An ...

Time is relative. The ticking of the clock, even of the most precise clocks we can make, does not exist in an absolute. It ...

In 2008, a team of UCLA-led scientists proposed a scheme to use a laser to excite the nucleus of thorium atoms to realize extremely accurate, portable clocks. Last year, they realized this ...

Scientists have made a major step towards building the world’s first practical nuclear clock.In a study published today in Nature, the team demonstrate a completely new way of probing the tiny ...

Atomic clocks will only see a loss of 1 second in accuracy over a period of 10 million years. They are used in multiple ways, including the GPS in your car. Now researchers have found a way to bypass ...

Researchers are looking for new ways to improve timekeeping because even small gains in stability can help physicists discover subtle physical effects. The thorium-229 nuclear clock is a newer venture ...

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 ...

Last year, a UCLA-led team accomplished something scientists have been trying to do for 50 years. They made radioactive thorium nuclei absorb and ...

A revolutionary achievement could pave the way for smaller, more efficient nuclear clocks. Last year, a research team led by UCLA achieved a milestone scientists had pursued for half a century. They s ...
