The National Institute of Standards and Technology (NIST) has dramatically enhanced the precision of time measurement with ...

At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could become 1,000 times more accurate than today's standards.

Whether you find yourself glancing at a clock on the wall or checking your phone, the time you constantly see is the product of a meticulous system upheld by the world’s timekeepers. In the U.S., a ...

Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards and Technology (NIST) campus in Boulder, Colorado. NIST-F4 measures an ...

This technology, called the 'microcomb chip,' could make optical atomic clocks, the most precise timekeepers in the world, compact enough for everyday use. Credit: Kaiyi Wu This breakthrough could ...

NPL's atomic clock, alongside clocks from around 80 labs worldwide, helps set Universal Coordinated Time (UTC), the official global time standard To pinpoint our exact location, we need to know ...

Humanity is closer to destroying itself, according to atomic scientists who revealed on Tuesday that the famous “Doomsday Clock” was set to 89 seconds to midnight — the closest it has ever been.

The Bulletin of the Atomic Scientists set the clock to 89 seconds before midnight – the theoretical point of annihilation. That is one second closer than it was set last year. The Chicago-based ...

WASHINGTON, Jan 28 (Reuters) - Atomic scientists on Tuesday moved their "Doomsday Clock" closer to midnight than ever before, citing Russian nuclear threats amid its invasion of Ukraine ...

The next generation of atomic clocks “ticks” at the frequency of a laser. That is around 100,000 times faster than the microwave frequencies of the caesium clocks that currently generate the second.
