On January 27th, the Bulletin of the Atomic Scientists will reveal the 2026 Doomsday Clock time. The announcement will occur ...

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...

The NPL has developed a miniaturised Atomic Fountain Clock that promises to make accurate timekeeping technology smaller.

A team of physicists has discovered a surprisingly simple way to build nuclear clocks using tiny amounts of rare thorium. By ...

Time dilation, a captivating concept embedded in Einstein’s theory of relativity, has been experimentally validated on Earth. With the use of ultra-precise clocks, scientists have been able to ...

Researchers at the ArQuS Laboratory of the University of Trieste (Italy) and the National Institute of Optics of the Italian National Research Council (CNR-INO) have achieved the first imaging of ...

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 ...

Dinosaur eggs laid 85 million years ago have been accurately dated using a new "atomic clock for fossils" method. The eggs could improve understanding of Earth's climate when dinosaurs roamed the ...

Physicists at the National Institute of Standards and Technology (NIST) have "entangled" or linked together the properties of up to 219 beryllium ions (charged atoms) to create a quantum simulator.
