The technology, enabled by thorium atoms, could keep time more accurately than atomic clocks and enable new discoveries about ...

Atomic clocks are very stable over long periods of time, meaning they are reliable for some of the most careful measurements scientists have to make. Ordinary clocks like those in your wristwatch ...

Here on Earth, it might not matter if your wristwatch runs a few seconds slow. But crucial spacecraft functions need accuracy down to one billionth of a second or less. Navigating with GPS, for ...

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 ...

Researchers have demonstrated a new optical atomic clock that uses a single laser and doesn't require cryogenic temperatures.

For decades, the world has kept time with the ticks of atomic clocks. But they could soon be a thing of the past, thanks to the introduction of a nuclear clock that could revolutionise how we ...

Such a device would greatly surpass the capabilities of atomic clocks, which define the span of a second through controlled energy jumps in atoms’ electrons and are currently the pinnacle of ...

The world keeps time with the ticks of atomic clocks, but a new type of clock under development—a nuclear clock—could revolutionize how we measure time and probe fundamental physics.

Atomic clocks have served as the world’s most precise means of measuring time for over 70 years, but their reign may be finally coming to an end. According to an announcement from the National ...

One example of this type of sensor is an atomic clock, which goes inside electronic devices to provide the same sort of precision referencing as wireless GPS. They could eliminate the need for the ...

Nuclear clocks would measure time based on changes inside an atom's nucleus, which would make them less sensitive to external disturbances and potentially more accurate than atomic clocks.
