On a campus in Boulder, Colorado, time just became a little more exact. Inside the National Institute of Standards and Technology, or NIST, a new atomic clock named NIST-F4 has begun to tick — not ...

The National Institute of Standards and Technology (NIST) U.S. has set a new world record for the most accurate aluminum ion-based optical atomic clock. This clock sets a new time-keeping benchmark, ...

Caesium atomic clock made by Louis Essen and J.V.L. Parry at the National Physical Laboratory, Teddington, London, 1955. Caesium atomic clock made by Louis Essen and J.V.L. Parry at the National ...

National timekeeping institution sought to enhance stability and precision to support critical national and international scientific work Adtran’s industry-first OSA 3300 SHP with optical pumping ...

The NPL has developed a miniaturised Atomic Fountain Clock that promises to make accurate timekeeping technology smaller.

Atomic clocks are the most accurate timekeepers we have, losing only seconds across billions of years. But apparently that’s not accurate enough – nuclear clocks could steal their thunder, speeding up ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...

The heart of a minuscule atomic clock—believed to be 100 times smaller than any other atomic clock—has been demonstrated by scientists at the Commerce Department’s National Institute of Standards and ...

A $5.5 billion upgrade to the Global Positioning System moved a step closer to launch this week when a prototype arrived at a Lockheed Martin complex in Colorado to begin months of tests.
