Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world measures one second in the near future. Researchers from Adelaide University ...

In the quest for ultra-precise timekeeping, scientists have turned to nuclear clocks. Unlike optical atomic clocks—which rely on electronic transitions—nuclear clocks utilize the energy transitions in ...

For the first time, scientists used an atomic nucleus as a clock. The world’s most precise timepieces are made using atoms, specifically their electrons. But clocks based on atomic nuclei — protons ...

The 2026 Doomsday Clock is ticking closer to midnight, signaling humanity edging to the "closest it has ever been to catastrophe" according to the Atomic Scientists, and the human race destroying ...

The Bulletin of Atomic Scientists has set the Doomsday Clock to 85 seconds to midnight. It is the closest the clock has ever been to midnight in its history. The Bulletin of Atomic Scientists said ...

The most precise clocks ever built can now detect gravity’s warping of time across a distance shorter than a pencil tip. That achievement, remarkable on its own, has physicists asking a deeper ...

The world is closer to destruction than ever before, the Bulletin of the Atomic Scientists, the group behind the "Doomsday Clock," argued. It added that the infamous clock is set at 85 seconds to ...

For decades, physicists have pursued a goal that sounds nearly impossible: to build a clock that keeps time using an atom's nucleus rather than the electrons orbiting it. "Having worked in this field ...

On January 28 th, the Bulletin of the Atomic Scientists will reveal the 2025 Doomsday Clock time at the United States Institute of Peace in Washington, DC. The announcement will occur during a live, ...
