Global phase spectroscopy' makes ultraprecise optical timekeepers even more precise Researchers at MIT say they have ...

Every second of modern life runs on precision — from GPS navigation to the time signals that keep the internet in sync. But ...

In a groundbreaking study, physicists have developed a new method for detecting dark matter, an invisible substance believed to account for around 80% of the universe’s mass. Using thorium-229, a ...

Scientists are close to creating a nuclear clock—an ultra-accurate clock that uses a low-energy transition in the nucleus of a thorium-229 atom to keep time. Electrical interference makes atomic ...

Optical clocks are highly precise timekeeping devices that measure time by tracking the oscillations of light, as opposed to microwaves, like conventional atomic clocks. The accuracy of these clocks ...

CHICAGO -- The Doomsday Clock has been set to its closest time to midnight in its history, the Bulletin of the Atomic Scientists announced Tuesday. The clock has now been set to 90 seconds to midnight ...

For nearly a century, scientists around the world have been searching for dark matter – an invisible substance believed to make up about 80 percent of the universe’s mass and needed to explain a ...

For the first time, scientists have dated dinosaur eggs that lay buried in rock for millions of years, using a groundbreaking new ‘atomic clock for fossils’ method. During the Cretaceous period, Earth ...
