The study shows that in quantum devices, reading a clock consumes far more energy than running it. This insight will help ...

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world ...

Determining the passage of time in our world of ticking clocks and oscillating pendulums is a simple case of counting the seconds between 'then' and 'now'. Down at the quantum scale of buzzing ...

The new Doomsday Clock time has been set by the Bulletin of the Atomic Scientists. Here’s what it means.

Did you know that one of the most common tests of cognitive function is asking the patient to draw a clock? Whether or not they mess it up, and in what way, can be indicative of any number of ...

Atomic clocks will only see a loss of 1 second in accuracy over a period of 10 million years. They are used in multiple ways, including the GPS in your car. Now researchers have found a way to bypass ...

Researchers at the UK’s National Physical Laboratory (NPL) have created a tiny atomic fountain ...

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could ...
