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

Since 1947 -- after the end of World War II and at the beginning of the Cold War -- the Science and Security Board of the ...

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.

At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...

Atomic clocks will only see a loss of 1 second in accuracy over a period of 10 million years. They are used in multiple ways, including the GPS in your car. Now researchers have found a way to bypass ...

A destructive windstorm disrupted the power supply to more than a dozen atomic clocks that keep official time in the United States.

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 ...
