Keeping time is easy, keeping precise time is hard, but a new type of clock based on atomic nuclei has pushed time-keeping ...

By using a rare thorium nucleus as a timekeeper, physicists have demonstrated the first working nuclear clock, a device that ...

First dreamed up decades ago, the world's first nuclear clocks are set to improve quickly, becoming more precise and aiding the hunt for dark matter.

These radical new devices keep time using fluctuations in the energy states of an atom’s nucleus, rather than those of its ...

But physicists have long dreamt of even better clocks that run on atomic nuclei, which are less sensitive to environmental disturbances. According to new research, that dream might soon become reality ...

Atomic scientists set their "Doomsday Clock" on Tuesday closer than ever to midnight, citing aggressive behavior by nuclear powers Russia, China, and the United States, fraying nuclear arms control, ...

To find out how clock accuracy is verified and which reference is used for comparison, we visited the Belarusian State Institute of Metrology (BelGIM), where most of the national standards are kept.

Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a smartphone screen. Yet despite its constant presence, time remains one of the ...

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.
