The advantage of a radio-controlled clock that receives the time signal from WWVB is that you never have to set it again. Whether it’s a little digital job on your desk, or some big analog wall clock ...

Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock. The devices, developed by Beichen Huang and colleagues at Tsinghua University and by Luca ...

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 ...

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 ...

Atomic clocks have been around for nearly 80 years, but their successors—nuclear clocks—are ready to take the stage. Two independent studies, both uploaded as preprints, report reliable timekeeping ...
