A collaboration between researchers in the US and Germany has made a major breakthrough in optical nuclear clocks, achieving laser-based excitation of Thoria-229 in a non-transparent host material.

Familiar risks to human existence such as nuclear weapons and climate change were cited by the scientists, along with new ...

A Chicago-based group of scientists have once again warned the world is closer than ever to human-made destruction by moving the symbolic “Doomsday Clock” up to 85 seconds to midnight.

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

In 2008, a team of UCLA-led scientists proposed a scheme to use a laser to excite the nucleus of thorium atoms to realize extremely accurate, portable clocks. Last year, they realized this ...

WASHINGTON (TNND) — The Bulletin of the Atomic Scientists set the Doomsday Clock to 85 seconds to midnight for 2026. The Doomsday Clock is a design that warns the public about how close we are to ...

Researchers from Los Angeles, Munich, and Mainz open new avenues for nucleus-based quantum technologies A research team from the University of California Los Angeles (UCLA), Ludwig Maximilian ...

To find out how clock accuracy is verified and which reference is used for comparison, we visited the Belarusian State Institute of Metrology (BelGIM), where most of the national standards are kept.

Chinese research team achieved a major breakthrough in continuous-wave vacuum ultraviolet (VUV) light sources, a longstanding bottleneck in the development of the nuclear clock, Science and Technology ...
