On Jan. 27, the Bulletin's Science and Security Board will reveal the 2026 Doomsday Clock time during a live, in-person news ...
The symbolic Doomsday Clock has been maintained by the Bulletin of the Atomic Scientists since 1947.
Since 1947 -- after the end of World War II and at the beginning of the Cold War -- the Science and Security Board of the Bulletin of Atomic Scientists have kept what they call a "Doomsday Clock." ...
For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more ...
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 ...
Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical lattice (i.e., a grid of laser light). By oscillating between two distinct ...
