Scientists are exploring a new type of optical atomic clock based on ytterbium-173 ions that could help define the future standard for measuring time.

Will birthdays go the way of the Betamax and Blackberry? Our culture is always eager to move away from old things toward new things and these days if you want to know how old you are, the number of ...

I have appraised all types of clocks — tallcase clocks, carriage clocks, mantel clocks and more — for clients in all parts of the world. These clock collectors have been surprised, or even stunned, ...

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 ...

Hickory dickory dock, this nucleus could make a great clock. A special variety of the element thorium hosts an atomic nucleus that could be used to keep time, scientists say. In a first, researchers ...

The world keeps time with the ticks of atomic clocks, but a new type of clock under development—a nuclear clock—could revolutionize how we measure time and probe fundamental physics. An international ...
