A collaboration between researchers in the US and Germany has made a major breakthrough in optical nuclear clocks, achieving laser-based excitation of Thoria-229 in a non-transparent host material.

Familiar risks to human existence such as nuclear weapons and climate change were cited by the scientists, along with new ...

A nuclear transition such as that in thorium-229 will be much less disturbed in the solid state, and its clock transition will be mostly preserved even in a crystal environment. The solid-state ...

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 ...

A Chicago-based group of scientists have once again warned the world is closer than ever to human-made destruction by moving the symbolic “Doomsday Clock” up to 85 seconds to midnight.

In 2008, a team of UCLA-led scientists proposed a scheme to use a laser to excite the nucleus of thorium atoms to realize extremely accurate, portable clocks. Last year, they realized this ...
