The Doomsday Clock is a symbolic measure of how close scientists believe humanity is to global catastrophe ...

The 'Doomsday Clock' explained as the countdown shows it's the closest it has ever been to midnight with the 2026 ...

The Bulletin of Atomic Scientists have unveiled their update on the Doomsday Clock to signal how close we are to 'the end of civilization'.

The Bulletin of the Atomic Scientists announced on Jan. 27 that the hands of the Doomsday Clock moved forward four seconds ...

The Doomsday Clock has been moved to 85 seconds before midnight, the closest to global catastrophe. Nuclear escalation, ...

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could ...

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 ...

The European Space Agency (ESA) has launched one of its most precise science experiments to date — the Atomic Clock Ensemble in Space (ACES)—to the International Space Station (ISS). This is no ...

As well as being useful for creating an optical ion clock, this multi-ion capability could also be exploited to create quantum-computing architectures based on multiple trapped ions. And because the ...

Unlike other atoms (left), ytterbium-173 (right) has a large nuclear spin and a strongly deformed nucleus whose strong fields interact with the electron shell. This turns forbidden quantum jumps into ...

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 ...
