Cherry blossom season is a magical time everyone should experience. Don't know where to start? We've highlighted lovely spots ...

The challenge here is to shrink these systems down enough, so they actually fit in applications where they'd be most useful.

Researchers have explored the interplay between gravitational effects and quantum interactions in optical atomic clocks, revealing more about quantum entanglement in precision timekeeping.

The strontium optical lattice clock is the first of its kind to be commercially available and will cost about 500 million yen ($3.3 million).

The growing vulnerability of GPS not only threatens our daily conveniences but also compels us to counter signal manipulation ...

In less than a month, most Americans will lose an hour of sleep as clocks will shift ahead by one hour. Daylight saving time will begin, delaying the moment day becomes night more than four months ...

That means it will remain in effect through the first Sunday of November in most of the U.S. The clocks were last changed Nov. 3 at the end of daylight saving in 2024, "falling back" an hour.

Optical atomic clocks can be built by locking a microcomb tooth to a ultranarrow-linewidth laser, which in turn locks to an atomic transition with extremely high frequency stability. That way ...

They may also set themselves according to atomic clocks. They even adjust when we travel into different time zones if they are taken out of airplane mode upon arrival. A radio-controlled clock ...
