Gaby and Alex’s team developed a chip-scale atomic clock (CSAC) that is a little larger than a peanut. Rubidium atoms in the atomic beam provide the microwave quantum transition that is used by the ...

Officials said the error is likely too minute for the general public to clock it, but it could affect applications such as ...

NIST restored the precision of its atomic clocks after a power outage caused by a power outage disrupted operations. Discover how this crucial recovery ensures the accuracy of global timekeeping.

On a campus in Boulder, Colorado, time just became a little more exact. Inside the National Institute of Standards and Technology, or NIST, a new atomic clock named NIST-F4 has begun to tick — not ...
