The heart of a minuscule atomic clock—believed to be 100 times smaller than any other atomic clock—has been demonstrated by scientists at the Commerce Department’s National Institute of Standards and ...

World's first thorium-229 nuclear clock shows potential for ultra-precise timekeeping and fundamental physics tests.

A new type of miniature atomic clock could provide better timing over the span of weeks and months compared with current systems. Researchers at the National Institute of Standards and Technology ...

Atomic clocks leveraged the atom to keep time, but new innovations will use the nucleus itself.

Researchers in the Neutral Atom Optical Clocks Group at the National Institute of Standards and Technology (NIST), University of Colorado and Pennsylvania State University recently devised a new ...

DENVER (KDVR) — It is said that time is relative and passes differently depending on an observer’s relative motion and gravitational potential. Although some would argue time is a construct, it does ...

The device, which traps thousands of atoms to keep time, is "pushing the boundaries of what's possible with timekeeping." Reading time 2 minutes New clock just dropped, but it’ll only drop a second ...

As explained in a mailing list post by Jeffrey Sherman, a NIST supervisory physicist who maintains the institute’s atomic clocks, “The atomic ensemble time scale at our Boulder campus has failed due ...
