A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time. Known ...

At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could become 1,000 times more accurate than today's standards.

The size of this setup makes the optical atomic clock impractical for widespread use in applications like smartphones, ...

Picture a clock ticking so steadily that it doesn’t lose a second, even after running for 1 billion years. Scientists are now closer than ever to realizing that level of timekeeping precision ...

On Tuesday, the clock was set at 89 seconds to midnight — the closest the world has ever been to that marker, according to the Bulletin of the Atomic Scientists, which established the clock in 1947.

If an atomic clock fell out of sync with a nuclear clock, for example, some change in the underlying physics might be responsible. Only time will tell. Curious about the world?

Atomic scientists moved their "Doomsday Clock" closer to midnight than ever before, citing Russian nuclear threats amid its invasion of Ukraine and other factors underlying the risks of global ...

Each year for the past 78 years, the Bulletin of the Atomic Scientists has published a new Doomsday Clock, suggesting just how close – or far – humanity is to destroying itself. The next ...
