Scientists are exploring a new type of optical atomic clock based on ytterbium-173 ions that could help define the future standard for measuring time.

This breakthrough in precision timing is about the size of your fingernail and only loses one second every 30,000 years.

The "Doomsday Clock" which represents how near humanity is to catastrophe moved closer than ever to midnight on Tuesday as concerns grow over nuclear weapons, climate change and disinformation. The ...

Earlier on Jan. 26, the hands of the Doomsday Clock were set closer to midnight than they've ever been in its history. Citing a worldwide "failure of leadership," the Bulletin of the Atomic Scientists ...

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,” ...

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.

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 ...
