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 ...

Scientists have taken another giant step towards building the most precise clock ever imagined—one that could display not only the passage of time, but shifting rules of nature itself. An ...

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 — ...

On January 27th, the Bulletin of the Atomic Scientists will reveal the 2026 Doomsday Clock time. The announcement will occur ...

The Bulletin of the Atomic Scientists will be meeting in the new year to decide how close to 'midnight' we are at the present moment. This is going to be a much anticipated unveiling of the Doomsday ...

Researchers at the ArQuS Laboratory of the University of Trieste (Italy) and the National Institute of Optics of the Italian National Research Council (CNR-INO) have achieved the first imaging of ...
