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 ...

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 ...

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 ...

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 ...

Here’s what you’ll learn when you read this story: Atomic clocks have been around for nearly 80 years, but their successors—nuclear clocks—are ready to take the stage. Two independent studies, both ...

Sunderland striker William Isidor scored a stunning goal to give Haiti a 2-1 lead over Morocco and real hope of a first World Cup point on Wednesday, but they ultimately fell short in a 4-2 defeat by ...

Physicists at Paderborn University have, for the first time, experimentally demonstrated the so-called "return" of Rabi oscillations in semiconductor quantum dots. The phenomenon, which was first ...
