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 ...

On Tuesday, the Bulletin of the Atomic Scientists set the clock at 85 seconds to midnight, the closest it has ever been to the symbolic point representing the destruction of human civilisation ...

Atomic clocks, which power GPS, online transactions, and data networks, just became more precise. MIT physicists have developed a technique that doubles the accuracy of optical atomic clocks by ...

The most precise clocks ever built are now testing Einstein, hunting dark matter, and reshaping how we define time itself. The world’s most precise clocks are changing how we understand time itself: ...

A nuclear transition such as that in thorium-229 will be much less disturbed in the solid state, and its clock transition will be mostly preserved even in a crystal environment. The solid-state ...

How some of the world’s most precise clocks missed a very small beat. By Mike Ives and Adeel Hassan Time appeared to skip a beat last week when some of the world’s most accurate clocks were affected ...

The new Doomsday Clock time has been set by the Bulletin of the Atomic Scientists. Here’s what it means.

At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...

The geospatial sector, and the wider community, relies on precise timekeeping based on microwave atomic clocks. Is that about ...
