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

The threat of GPS jamming extends beyond aviation. Without GPS, our lives would grind to a halt: in 2017, a government report ...

These optical atomic clocks have broken record after ... This was the first actual demonstration of clock operation with such uncertainty. The system still has a lot more potential.

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 ...

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

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 at JILA ...

This 20 GHz offset frequency will serve as the clock signal that is electronically detectable. In this way, we could get the system to transfer the exact time signal from an atomic clock to a more ...

They may also set themselves according to atomic clocks. They even adjust when we travel into different time zones if they are taken out of airplane mode upon arrival. A radio-controlled clock ...
