MIT researchers double the accuracy of optical atomic clocks by reducing quantum noise with an innovative laser technique.

For the first time, scientists have dated dinosaur eggs that lay buried in rock for millions of years, using a groundbreaking ...

Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical lattice (i.e., a grid of laser light). By oscillating between two distinct ...

Every time you check the time on your phone, make an online transaction, or use a navigation app, you are depending on the precision of atomic clocks. Scientists are developing next-generation atomic ...

MIT physicists improved the stability of optical atomic clocks by reducing “quantum noise” — a fundamental measurement ...

Gov. Polis and others celebrated the Navy's 250th birthday at the Capitol Tuesday. D'Angelo, Grammy-winning R&B singer, dies ...

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 ...

Michigan is seeing shorter days, and in less than a month it will be dark much earlier when it's time to turn the clocks back an hour. Days will gradually get shorter leading up to the end of Daylight ...

Daylight saving time is coming to an end right after Halloween, despite sleep experts continually pushing to eliminate time changes.

British clockmaker Ian Westworth is bracing for a wave of concern this weekend from Londoners convinced the country's most ...
