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 ...

NIST traced the problem to its Boulder, Colorado campus, where a prolonged utility power outage disrupted operations. The ...

The emission of photons by excited nuclei has been explored for timekeeping and sensing, but nuclear processes that eject electrons offer practical advantages. Electrons in atoms can exist only in ...

Atomic clocks went out of sync after a severe windstorm knocked out power at a Denver laboratory and a backup generator ...
