Eighty years after the first atomic bombs fell on Hiroshima and Nagasaki, experts and survivors warn that the risk of a new ...

For decades, the world has kept time with the ticks of atomic clocks. But they could soon be a thing of the past, thanks to the introduction of a nuclear clock that could revolutionise how we ...

The HP 115BR is not one of the most well-known products from Hewlett-Packard. And yet, it was remarkably important ...

The Doomsday Clock at the U.S. Institute of Peace in Washington is seen at 89 seconds to midnight on Jan. 28, the closest the clock has ever been to midnight in its 78-year history, to signal that ...

In atomic clocks, an atom’s electrons are pinged with electromagnetic radiation at specific frequencies. Bursts of energy excite the electrons, pushing them into a higher orbit around the atom.

Ekkehard Peik, one of the field’s pioneers, says such a clock could be a factor of 1,000 times better than today’s standard atomic clocks.

Scientists have developed the most accurate atomic clock – 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 services like ...

Nuclear clocks would keep time using a variety of the element thorium, called thorium-229. Most atomic nuclei make energy leaps that are too large to be triggered by a tabletop laser.

Forget the atomic clock! World's first NUCLEAR clock is unveiled – paving the way for ultraprecise timekeeping READ MORE: Scientist says a 'negative leap second' will be needed in 2029 ...

Atomic scientists on Tuesday moved their "Doomsday Clock" closer to midnight than ever before, citing Russian nuclear threats amid its invasion of Ukraine, tensions in other world hot spots, military ...
