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

Every second of modern life runs on precision — from GPS navigation to the time signals that keep the internet in sync. But ...

(TNS) — In 2003, engineers from Germany and Switzerland began building a bridge across the Rhine River simultaneously from both sides. Months into construction, they found that the two sides did not ...

A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time. Known as NIST-F4, ...

"In setting the clock closer to midnight, we send a stark signal. Because the world is already perilously close to the precipice, any move towards midnight should be taken as an indication of extreme ...
