Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock. The devices, ...

But physicists have long dreamt of even better clocks that run on atomic nuclei, which are less sensitive to environmental ...

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

A clock based on radioactive thorium atoms realises a long-held ambition, demonstrating a technology that could eventually ...

Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a ...

The world’s first nuclear clocks have ticked. A team of physicists has demonstrated a ...

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.

Physicists have demonstrated all the ingredients of a nuclear clock — a device that keeps time by measuring tiny energy shifts inside an atomic nucleus. Such clocks could lead to vast improvements in ...

Researchers have demonstrated a new optical atomic clock that uses a single laser and doesn't require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks without ...
