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 ...

Denver, Colorado | Physicists are getting closer to creating a long-sought ‘nuclear clock’. This device would keep time by measuring energy transitions in the nuclei of atoms and could become the most ...

Researchers at Wuhan University (WHU) in China have produced a commercially manufacturable atomic clock less than one-seventh the size of its smallest US counterpart for use in satellites, drones and ...

Ludovica Castelli (Ph.D.) is Project Manager of the EU Non-Proliferation and Disarmament Consortium Project at the Istituto Affari Internazionali (IAI). She holds a Ph.D. from the University of ...

You can buy all kinds of conventional clocks that have hands and numbers for easy reading. Or, like [Fabio Ricci], you could build yourself something a little more esoteric, like this neat shadow ...

Satellite imagery shows that Iran could have transferred to Isfahan up to 540 kilograms—possibly all—of its highly-enriched uranium inventory before the June strikes last year. The International ...

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world measures one second in the near future. Researchers from Adelaide University ...
