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

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

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 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 ...

“Atomic clocks and our computer networks are the new, far superior form of time measurement, but we’re forcing them to keep in sync with this older form of measurement,” remarks Dr. David Gozzard, an ...

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 ...

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 ...
