Atomic clocks are the most accurate timekeepers we have, losing only seconds across billions of years. But apparently that’s not accurate enough – nuclear clocks could steal their thunder, speeding up ...

The best timepieces tend to be fragile, but a device based on iodine threads the needle between precision and practicality. Atomic clocks are usually either ultra-precise or sturdy, but not both. Now, ...

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 timekeeping device is made with atomic nuclei of thorium, although it is not yet more precise than standard atomic clocks. Reading time 2 minutes Meet the “nuclear” clock: a device that marks the ...

NIST scientists have published results establishing a new atomic clock, NIST-F4, as one of the world’s most accurate timekeepers, priming the clock to be recognized as a primary frequency standard — ...
