Researchers 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 ...

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 ...

An international research team has taken a decisive step toward a new generation of atomic clocks. At the European XFEL X-ray laser, the researchers have created a much more precise pulse generator ...

Some alarm clocks do a lot more than tell the time and wake you up. Oregon Scientific, for example, makes a line of self-setting clocks that let you project an image of the digital clock face and ...

Have you ever thought to use a clock to identify mineral deposits or concealed water resources within the Earth? An international team headed by astrophysicists Philippe Jetzer and Ruxandra Bondarescu ...

Atomic clocks. They almost sound like something out of science fiction, or an experiment confined to some elite physics lab, but in reality, they’ve been around since the 1950s in one form or another.
