JILA researchers are pioneering a nuclear clock using thorium-229, which offers unprecedented stability compared to atomic ...

With access to a 10-MHz timebase from a cesium fountain atomic clock — no less a clock than the one that’s used to define the SI second, by the way — [Daniel] looked for ways to sync the ...

The clock hands are set by the Bulletin of the Atomic Scientists, a group formed by Manhattan Project scientists at the University of Chicago who helped build the atomic bomb but protested using it ...

Even your Macbook or smartphone displays time which is synchronized to the NIST-F1 clock, a cesium fountain atomic clock (aka the ‘Atomic Clock’) that is part of a global consortium of atomic ...

This scene is rendered unforgettable by a depiction of the Doomsday Clock with its minute hand pointing at 15 seconds to midnight. In real life, the U.S. Bulletin of the Atomic Scientists reset ...

For decades, atomic clocks have been the pinnacle of precision timekeeping, enabling GPS navigation, cutting-edge physics research, and tests of fundamental theories. But researchers are now pushing ...

A new study investigated the mortality and mental health correlates of the iconic Bulletin of the Atomic Scientists' Doomsday Clock.

Results indicate the closer the Doomsday Clock ticks to midnight, the higher the rates are for mortality specific to Alzheimer's disease, suicide ...

The scientists confirmed the phenomenon caused by differing gravity levels at different altitudes using Katori's compact atomic lattice clock, which is still about the size of a household fridge.
