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 improve ...

Atomic clocks have long been the gold standard for measuring time and frequency. Among them, optical clocks—using atoms like strontium or aluminum—have reached staggering levels of accuracy, with ...

Improvements in clocks are setting the stage for a redefinition of the second. This is an Inside Science story. (Inside Science) -- Earlier this year, in a nondescript lab at the National Institute of ...

Time zones are a complicated but necessary evil. Humans like the numbers on the clock to vaguely match up with what the sun is doing in the sky outside. To that end, different places in the world keep ...

The world’s most accurate clock now belongs to researchers at the National Institute of Standards and Technology (NIST). Its new optical atomic clock, built around a single trapped aluminum ion, can ...

The experts who maintain the ominous Doomsday Clock said Tuesday that humanity is still as close as ever to global catastrophe, which could involve nuclear war, climate change, or maybe even ...

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 world is closer than ever to destruction, according to the Doomsday Clock, an attempt by the Chicago-based Bulletin of the Atomic Scientists to warn world leaders and civilians of man-made global ...

Each year for the past 78 years, the Bulletin of the Atomic Scientists has published a new Doomsday Clock, suggesting just how close – or far – humanity is to destroying itself. The next edition of ...

LANCASTER COUNTY, Pa. (WHTM) — A Guinness World Record-winning clock is now on display at the National Watch and Clock Museum in Lancaster County. According to the museum, the Burgess Clock B received ...
