How some of the world’s most precise clocks missed a very small beat. By Mike Ives and Adeel Hassan Time appeared to skip a beat last week when some of the world’s most accurate clocks were affected ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? Researchers recently announced a big step forward in the development of a nuclear ...

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 ...

We are all familiar enough by now with the succession of boards that have come from Raspberry Pi in Cambridge over the years, ...

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 ...

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 ...

NIST confirmed several public time servers lost their atomic reference signal A generator failure interrupted the distribution of America’s primary atomic time scale Some NIST servers responded ...

Have you heard the saying “the problem is the solution”? It seems to originate in the permaculture movement, but it can apply equally well to electronics. Take the problem [shiura] ...

The Bulletin of the Atomic Scientists is little more than a decade older than the field of artificial intelligence, whose birth can arguably be traced back to the Dartmouth Summer Research Project on ...

Eighty years after the founding of the Bulletin of the Atomic Scientists, and 55 years after the first Earth Day, humanity faces a growing profusion of existential threats. Most people—including ...

The U.S. government calculates the country's official time using more than a dozen atomic clocks at a federal facility northwest of Denver. But when a destructive windstorm knocked out power to the ...
