Perfect timekeeping is more complicated than you think. Most clocks slow down over time (not that many people notice), and tiny imperfections in the manufacturing process ensure that no two timepieces ...

For decades, scientists have tried to build a device even more precise than an atomic clock, which keeps time using electrons, the negatively charged particles that whiz around in an atom. Now, two ...

Two teams of physicists have made the world’s first nuclear clocks. These radical new devices keep time using fluctuations in the energy states of an atom’s nucleus, rather than those of its electrons ...

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 ...

The world's first nuclear clocks have ticked. A team of physicists has demonstrated a working timekeeping device regulated not by orbiting electrons — as in conventional atomic clocks — but by ...

Scientists have built the first working nuclear clock, which uses the vibrations of atomic nuclei to keep time. Nuclear clocks have been sought after for more than two decades and could eventually ...

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 ...

Humanity has used clocks since we became aware of the concept of time. And as technology has improved, so have our time-keeping methods. Today, many people rely on digital clocks to track the hours ...

Microchip Technology has expanded its Tuscaloosa plant to meet growing demand for its precision timing systems. The facility produces hydrogen masers, which are atomic clocks used in cell networks, ...

Adelaide University researchers have successfully tested a new type of portable atomic clock at sea for the first time, using technology that could help power the next generation of navigation, ...
