A team of physicists has discovered a surprisingly simple way to build nuclear clocks using tiny amounts of rare thorium. By ...

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 ...

Since 1947 -- after the end of World War II and at the beginning of the Cold War -- the Science and Security Board of the ...

The emission of photons by excited nuclei has been explored for timekeeping and sensing, but nuclear processes that eject electrons offer practical advantages. Electrons in atoms can exist only in ...

The NPL has developed a miniaturised Atomic Fountain Clock that promises to make accurate timekeeping technology smaller.

Researchers at the ArQuS Laboratory of the University of Trieste (Italy) and the National Institute of Optics of the Italian National Research Council (CNR-INO) have achieved the first imaging of ...
