Do moon phases really affect fishing success? Explore the history of Solunar theory and see how the Citizen Tsuki-yomi A-T ...

The watch on your wrist might seem pretty accurate on a day-to-day basis but it’s got nothing when compared to atomic clocks. Scientists use atomic clocks for a variety of purposes, and the more ...

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 ...

The Doomsday Clock was moved forward on Tuesday to 90 seconds to midnight due in part to worries over Russian's veiled threats of nuclear warfare.

The resulting atomic clocks that set official international times today are astonishingly robust, losing only about one second every 100 million years.

Scientists have developed the most precise and accurate atomic clock to date – if you ran it for twice the current age of the universe, it would only be off by one second. This could not only ...

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 ...

Atomic clocks use these frequencies — specifically, absorbing and emitting photons at regular intervals to keep time. They are the most accurate clock we have to measure time in seconds.

According to scientists at NIST in Boulder, their newest atomic clock, the NIST-F4, will help track time more precisely and help put global time on a more accurate frequency.

The First Nuclear Clock Will Test if Fundamental Constants Change An ultra-precise measurement of a transition in the hearts of thorium atoms gives physicists a tool to probe the forces that bind the ...

Several manufacturers already offer affordable watches that synchronise to the radio signals transmitted from atomic clocks around the world, but Hoptroff's 'No.10' movement is different because it ...

The Bulletin of the Atomic Scientists unveiled its latest reading of the Doomsday clock on Tuesday morning, signaling how close humanity is to global catastrophe.
