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.

The Doomsday Clock was set closer to midnight than it’s ever been before on Jan. 27. The Doomsday Clock is a symbol created by the Bulletin of the Atomic Scientists in June 1947 to show how close ...

This is the third time that the clock has been moved closer to midnight in the past five years. “Every second counts, and we are running out of time. It is a hard truth, but this is our reality,” ...

Complacency about the serious challenges the world is facing is not an option. But the idea that we are almost at the point ...

WASHINGTON — Atomic scientists set their "Doomsday Clock" on Tuesday closer than ever to midnight, citing aggressive behavior by nuclear powers Russia, China and the United States, fraying nuclear ...

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 ...

What if the key to unlocking new physics lies in keeping better time? Inside the quiet journey to build a nuclear clock so precise, it could redefine our understanding of reality. Researchers are ...

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world measures one second in the near future. Researchers from Adelaide University ...

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.
