There's a new record holder for the most accurate clock in the world. Researchers at the National Institute of Standards and Technology (NIST) have improved their atomic clock based on a trapped ...

This particular clock is technically an ion clock, which is different from the more common atomic clocks that are based on measuring the resonant frequencies of a single cesium atom to regulate time ...

Researchers from six countries conducted the largest coordinated comparison of optical clocks to date. The measurements amount to the largest coordinated comparison of optical clocks to date, and ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. The ongoing race to create the next generation of hyperaccurate ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...

Improvements in clocks are setting the stage for a redefinition of the second. This is an Inside Science story. (Inside Science) -- Earlier this year, in a nondescript lab at the National Institute of ...

Inside a laboratory nestled in the foothills of the Rocky Mountains, amid a labyrinth of lenses, mirrors, and other optical machinery bolted to a vibration-resistant table, an apparatus resembling a ...

The next generation of atomic clocks “ticks” at the frequency of a laser. That is around 100,000 times faster than the microwave frequencies of the caesium clocks that currently generate the second.
