A powerful laser generates ultraviolet light as it shines into a jet of gas. For a nuclear clock to work in a new study, scientists used UV light to excite nuclear particles in an atom of thorium-229.

Using thin-film technology in nuclear clocks is commensurate with semiconductors and photonic integrated circuits, suggesting that future nuclear clocks could be more accessible and scalable.

A clock that ticks at the nuclear level. At the heart of this effort lies thorium-229, a rare isotope with a one-of-a-kind feature: it has a nuclear state that can be triggered using laser light.

Trump was quite clear: Tehran tyrants need to offer up fully-verifiable proof that their nuke quest is stopped, or Washington (and Jerusalem) will stop it for them — and the clock is ticking ...

Mideast envoy Steve Witkoff is holding a sixth round of talks with Tehran Sunday as Israel considers strikes against Iran.

Nuclear clocks, however, would apply these concepts at exponentially more fine-tuned parameters. As its name implies, these devices focus on the vibrations from a single nucleus as opposed to ...

Atomic clocks are our most accurate timekeepers, losing only seconds across billions of years. But nuclear clocks could steal their thunder, speeding up GPS and the internet. Now, scientists have ...

After Israel's strikes, Iran retains its scientific expertise, and now has a stronger incentive to bury its program even ...

The main risk inside the storage facility is the chemical toxicity of uranium hexafluoride gas and fluoride compounds ...

A wake-up call is sounded in the latest reports on the extent of damage America meted out to Iran’s nuclear program.
