"In setting the clock closer to midnight, we send a stark signal. Because the world is already perilously close to the precipice, any move towards midnight should be taken as an indication of extreme ...

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 ...

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 ...

The Bulletin of the Atomic Scientists set the Doomsday Clock to 89 seconds to midnight, one second more than the last two years, attributed to threats posed by climate change and artificial ...

The nucleus of an atom is now the modern version of sand flowing through an hourglass. Researchers have spent 15 years trying to increase accuracy in timekeeping. The U.S. standard currently relies on ...

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 ...

Ekkehard Peik is a clock-maker. But instead of spending his days looking at tiny cogs and springs through a magnifying glass, the tools of his trade are powerful lasers, wires and, occasionally, ...

Atomic clocks and frequency standards represent the pinnacle of precision timekeeping technology. By harnessing the natural oscillatory behaviour of atoms, these devices deliver unparalleled accuracy ...

The heart of a minuscule atomic clock—believed to be 100 times smaller than any other atomic clock—has been demonstrated by scientists at the Commerce Department’s National Institute of Standards and ...

For more than a century, dinosaur eggs have offered haunting snapshots of ancient life, from curled embryos to trampled nests ...
