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

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 ...

STATEN ISLAND, N.Y. — Daylight Saving Time ends a bit earlier than it has in recent years. We’ll “fall back” to Standard Time on Sunday, Nov. 2, at 2 a.m., making the Daylight Saving Time period one ...

This weekend, Daylight Saving Time will end and clocks will move by an hour. Which way to I change it? Here's what to know in ...

Scientists have taken another giant step towards building the most precise clock ever imagined—one that could display not only the passage of time, but shifting rules of nature itself. An ...

While the rest of nature rises and slumbers to lunar and solar cycles, humans work and sleep to the resetting of their artificial clocks.

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 ...

On May 2, 2011, a US Navy SEAL helicopter soft-crashed into the side of Osama bin Laden’s compound in Abbottabad, Pakistan. Within the hour, bin Laden was identified and assassinated. The world’s most ...

Your body may have gotten used to the sunsets before 6 p.m. But come these weekend, they'll be even earlier -- by about 60 ...

The days of mid-afternoon sunsets are almost upon us as winter draws nearer. A few days after Halloween, most of the US will be moving the clocks backward one hour. Daylight saving time ends on Nov. 2 ...

Throughout history, humans have always searched for ways to predict the future. AI is just the latest tool to try to predict how humans will behave. While some believe that predictive tools can be ...
