For decades, nuclear clocks have existed as one of physics’ most tempting promises. A ...

Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a ...

World's first thorium-229 nuclear clock shows potential for ultra-precise timekeeping and fundamental physics tests.

A clock based on radioactive thorium atoms realises a long-held ambition, demonstrating a technology that could eventually ...

But physicists have long dreamt of even better clocks that run on atomic nuclei, which are less sensitive to environmental ...

Adelaide University researchers have successfully tested a new type of portable atomic clock at sea for the first time, using technology that could help power the next generation of navigation, ...

When it comes to navigation in outer space, keeping precise time is incredibly important, that's why NASA needs to use ...

For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ytterbium to create a new type of atomic clock that is both highly precise and ...

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 ...
