Atomic clocks leveraged the atom to keep time, but new innovations will use the nucleus itself.

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.

Add Yahoo as a preferred source to see more of our stories on Google. A new study suggests trapped-ion atomic clocks could detect quantum superpositions of time, opening a path toward uniting quantum ...

For decades, scientists have tried to build a device even more precise than an atomic clock, which keeps time using electrons ...

World's first thorium-229 nuclear clock shows potential for ultra-precise timekeeping and fundamental physics tests.

Two teams of physicists have made the world’s first nuclear clocks. These radical new devices use fluctuations in the energy ...

Every time you check the time on your phone, make an online transaction, or use a navigation app, you are depending on the precision of atomic clocks. Scientists are developing next-generation atomic ...

Is Einstein's assumption about gravity and time correct? Researchers want to find out with the help of two clocks. And send ...

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.

Atomic clocks are established as the most precise timekeepers created. Atomic clocks work by deploying lasers to measure the vibrations of atoms (electromagnetic signals). By atoms oscillating at a ...

Without precise time, the modern world collapses - from GPS to the electricity grid. And Switzerland is one of the clock ...
