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

A tomic clocks, which power GPS, online transactions, and data networks, just became more precise. MIT physicists have developed a technique that doubles the accuracy of optical atomic clocks by ...

MIT physicists improved the stability of optical atomic clocks by reducing “quantum noise” — a fundamental measurement ...

Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical ...

CHICAGO -- The Doomsday Clock has been set to its closest time to midnight in its history, the Bulletin of the Atomic Scientists announced Tuesday. The clock has now been set to 90 seconds to midnight ...

For the first time, scientists have dated dinosaur eggs that lay buried in rock for millions of years, using a groundbreaking new ‘atomic clock for fossils’ method. During the Cretaceous period, Earth ...

DENVER (KDVR) — It is said that time is relative and passes differently depending on an observer’s relative motion and gravitational potential. Although some would argue time is a construct, it does ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block, the ...

NIST scientists have published results establishing a new atomic clock, NIST-F4, as one of the world’s most accurate timekeepers, priming the clock to be recognized as a primary frequency standard — ...

In a video demonstration, Microchip Technology’s chip-scale atomic clocks reveal their low phase noise and application ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...
