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 ...

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

Scientists have made a major step towards building the world's first practical nuclear clock.In a study published today in Nature, the team ...

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

Summary: Time doesn’t flow uniformly across the solar system, and new research reveals just how differently it unfolds on Mars compared with Earth. By tracing subtle gravitational and orbital ...

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 ...

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 ...

Physicist Heinz von Foerster predicted back in 1960 that the world would end in 2026. von Foerster stated in his prediction ...

Scientists have made a major step towards building the world’s first practical nuclear clock.In a study published today in Nature, the team demonstrate a completely new way of probing the tiny ...

Whilst early trials can lay the foundations, full scale deployment of quantum technologies for financial services will only ...

Physicists found that clocks on Mars will tick 477 microseconds (millionths of a second) faster than on Earth per day, on ...

The classic 1950s living room was more than a place to sit, it was a carefully arranged stage for family life, television ...
