MIT researchers double the accuracy of optical atomic clocks by reducing quantum noise with an innovative laser technique.

An orange tabby cat has officially earned the title of "cutest alarm clock," but her owner has forgiven her for her early-morning antics. A 6 a.m. wake-up call might not be the most convenient, but ...

Physicists have demonstrated all the ingredients of a nuclear clock — a device that keeps time by measuring tiny energy shifts inside an atomic nucleus. Such clocks could lead to vast improvements in ...

To say “I’m not a morning person” would be an understatement. Not only is it hard for me to be useful in the first hour (or so) of being awake, but it’s hard for me to wake up. I mean, really hard.

Scientific clockmakers have crafted a prototype of a nuclear clock, hinting at future possibilities for using atomic nuclei to perform precise measurements of time and make new tests of fundamental ...
