For decades, scientists have tried to build a device even more precise than an atomic clock, which keeps time using electrons, the negatively charged particles that whiz around in an atom. Now, two ...
Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock. The devices, developed by Beichen Huang and colleagues at Tsinghua University and by Luca ...
All it takes is one scroll through X or TikTok, or a conversation with a group of Gen Z friends spilling the tea, to hear the phrase "clock it!" At first, it sounds like someone is asking you for the ...
Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.

Clocks "spring forward" in the U.S. and Canada on March 8 and in the U.K. and Europe on March 29. Here's exactly when — and why — we have daylight saving time. It’s almost time to change the ...
All living creatures are affected by the cycles of celestial objects. Humans have always been locked into the rhythms of sunrise and sunset, the phases of the Moon, and the seasons. We left some of ...
The Bulletin of the Atomic Scientists announced on Jan. 27 that the hands of the Doomsday Clock moved forward four seconds and now sits at 85 seconds to midnight—the closest the symbolic clock has ...
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 ...
Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...
Many people in the United States may have their circadian rhythm thrown off come Sunday morning, Nov. 2, due to daylight saving time ending. Clocks will "fall back" to standard time this year at 2 a.m ...
Daylight saving time ends this Sunday at 2:00 a.m. It was introduced in 1918 as a way to conserve energy by making the most of summer’s daylight hours. But some people say that shifting our clocks is ...
