Two independent teams of scientists have created the first functional clocks that can keep ultraprecise time using the nuclei of a radioactive element ...

By using a rare thorium nucleus as a timekeeper, physicists have demonstrated the first working nuclear clock, a device that could lead to even more precise clocks and new ways to search for dark ...

For the first time, scientists used an atomic nucleus as a clock. The world’s most precise timepieces are made using atoms, specifically their electrons. But clocks based on atomic nuclei — protons ...

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.
