Time appeared to skip a beat last week when some of the world’s most accurate clocks were affected by a wind-induced power ...

A destructive windstorm disrupted the power supply to more than a dozen atomic clocks that keep official time in the United ...

Due to the power outage, time (very) briefly stood still at the NIST Internet Time Service facility in Boulder.

Officials said the error is likely too minute for the general public to clock it, but it could affect applications such as critical infrastructure, telecommunications and GPS signals.

Researchers develop a method to count thorium-229 nuclear ticks, paving the way for high-precision nuclear clocks and sensors.

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

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 ...

A research team from the University of California Los Angeles (UCLA), Ludwig Maximilian University of Munich (LMU), and Johannes Gutenberg University Mainz (JGU) has succeeded in exciting the atomic ...

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

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 ...

The National Institute of Standards and Technology’s Internet Time Service Facility in Boulder lost power Wednesday afternoon ...
