"As the typical uncertainty of time transfer over the public Internet is on the order of one millisecond (1/1000th of a ...

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 ...

Time on Mars does not match time on Earth, and the difference is no longer a thought experiment. Precision calculations now show that clocks on the red planet tick measurably faster, confirming a ...

A revolutionary achievement could pave the way for smaller, more efficient nuclear clocks. Last year, a research team led by UCLA achieved a milestone scientists had pursued for half a century. They s ...

Last year, a UCLA-led team accomplished something scientists have been trying to do for 50 years. They made radioactive thorium nuclei absorb and ...

Even as quantum navigation emerges as a legitimate alternative to satellite-based navigation, the satellites themselves are ...

In the 80th year of the nuclear age, with just 89 seconds left on the Doomsday Clock, every nuclear challenge is trending in ...

A small group of scientists and policy experts meet behind closed doors in Chicago to decide how close humanity is to ...

AI is already sufficiently robust that it introduces new global risks and exacerbates existing threats. Its development is ...

Advances in precision, new levels of resistance to shocks or magnetism: innovation remains a driving force for the watch ...

A research team at VTT MIKES has set a new record in optical-clock absolute frequency measurements using a strontium single-ion clock with exceptionally low uncertainty and high uptime.

Power Metals entered into a cesium concentrate offtake agreement with Albemarle Corporation, a US$16 billion global critical ...
