A team of physicists has discovered a surprisingly simple way to build nuclear clocks using tiny amounts of rare thorium. By ...

A collaboration between researchers in the US and Germany has made a major breakthrough in optical nuclear clocks, achieving laser-based excitation of Thoria-229 in a non-transparent host material.

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

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

The goal of the Defense Advanced Research Projects Agency’s (DARPA’s) Chip-Scale Atomic Clock (CSAC) program is to provide warfighters with enhanced radio communications and jam-resistant navigation ...

Atomic clocks are the most accurate timekeepers we have, losing only seconds across billions of years. But apparently that’s not accurate enough – nuclear clocks could steal their thunder, speeding up ...

Atomic clocks and frequency standards represent the pinnacle of precision timekeeping technology. By harnessing the natural oscillatory behaviour of atoms, these devices deliver unparalleled accuracy ...

Since 1947 -- after the end of World War II and at the beginning of the Cold War -- the Science and Security Board of the ...

This is an atomic clock that uses the predictable frequency of ytterbium atoms absorbing and emitting light to tell time. A new experiment paired a ytterbium-based atomic clock with two others that ...

From freeze-dried strawberries to memory foam and scratch-resistant glasses, space exploration is the force behind a myriad of life-changing innovations. Now it’s time for a terrestrial innovation to ...

It was 2:30 in the morning when astronautical engineer Todd Ely watched as a little atomic clock—the size of a four-slice toaster—was launched into space on a satellite attached to one of the most ...

NTP is one of the most interesting and important, but all to forgotten, protocols that makes the internet tick. Accurate ...
