NIST restored the precision of its atomic clocks after a power outage caused by a power outage disrupted operations. Discover ...

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

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 ...

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.

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

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

Scientists create a record 19.2-attosecond soft X-ray pulse, capturing electron motion in real time for the first time.
