Scientists are developing nuclear clocks using thin films of thorium tetrafluoride, which could revolutionize precision ...

At the cutting-edge Facility for Rare Isotope Beams, researchers have precisely measured the mass of aluminum-22, revealing ...

A nuclear-powered car sounds like something straight out of science fiction, but it was actually something people were ...

Unlike optical atomic clocks—which rely on electronic transitions—nuclear clocks utilize the energy transitions in the atom's ...

Atomic clocks that excite the nucleus of thorium-229 embedded in a transparent crystal when hit by a laser beam could yield the most accurate measurements ever of time and gravity, and even rewrite ...

As a warning about how close we are to atomic holocaust, the Doomsday Clock stands at 90 seconds to midnight, the closest it has ever been since its invention in 1947. After creating the world's first ...

John Ferguson, a military veteran with over 25 years of experience in the drone technology field, said the only reason for ...

The new age began on a chill, grey afternoon 20 years ago. The site was a laboratory in a squash court beneath the stands of the University of Chicago's old Stagg Field Stadium. Gathered ...

In a sense, U.S. nuclear weapons exist not to be used. And while nuclear threats seem far away, a tool from one group brings the scenario close to home.

Scientists have taken a big step forward in precision timekeeping by developing a safer and more affordable way to build ...

But uranium enriched to 5 percent is used to fuel most civilian nuclear reactors, while the purity level must be raised to roughly 90 percent for atom bombs. Iran agreed to give up much of its ...
