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

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

“Humanity Edging Closer To Catastrophe”: Iconic Doomsday Clock moves one second closer to midnight as global existential threats rage. Clock factors include nuclear weapons, climate crisis, artificial ...

The Doomsday clock was set at 89 seconds to midnight on Tuesday morning, putting it the closest the world has ever been to what scientists deem "global catastrophe." The decades-old international ...

Every single day, humans rely on hundreds of hidden clocks. GPS location, Internet stability, stock trading, power grid management ... all rely on atomic clocks in order to work. Many of those clocks ...

The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these measurements far more accurate. In 2003, engineers from Germany and ...

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, ...

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 ...

An Arizona-based company has launched its next generation of low-noise Chip-Scale Atomic Clock (CSAC). Microchip's model SA65-LN is designed to operate in a wider temperature range, enabling low-phase ...

Based on the rising and falling of cesium atoms under a microwave beam, the NIST-F4 atomic clock is so reliable that if it had started to run when dinosaurs existed 100 million years ago it would be ...
