Chinese scientists have engineered a clock so accurate it could lead to a redefinition of the second and an ultraprecise global time standard. The new optical clock is so accurate that it loses or ...

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 ...

Adelaide University researchers have successfully tested a new type of portable atomic clock at sea for the first time, using ...

What a makes a good clock? Andrew Ludlow, a physicist at the National Institute of Standards and Technology, says one of the most important criteria is stability. "If you could imagine a grandfather ...
