"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 ...

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 ...

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 next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second at ...

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, ...

STATEN ISLAND, N.Y. — When Daylight Saving Time arrives next month, we have to set our clocks ahead one hour. But do we, really? Many of the clocks we rely on daily actually do the resetting all by ...

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 ...

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 National Institute of Standards and Technology recently warned that an atomic clock device installed at its Boulder campus had failed due to a prolonged power ...
