A research team led by Prof. Chang Hong from the National Time Service Center (NTSC) of the Chinese Academy of Sciences (CAS) has developed a strontium optical lattice clock with both frequency ...

BOULDER, Colo -- Heralding a new age of terrific timekeeping, a research group led by a National Institute of Standards and Technology (NIST) physicist has unveiled an experimental strontium atomic ...

In another advance at the far frontiers of timekeeping , the latest modification of a record-setting strontium atomic clock has achieved precision and stability levels that now mean the clock would ...

A University of Tokyo and RIKEN research group has developed a mercury-based optical lattice clock and measured the mercury clock frequency using the same group's recently developed strontium-based ...

BOULDER, Colo.- A next-generation atomic clock that tops previous records for accuracy in clocks based on neutral atoms has been demonstrated by physicists at JILA, a joint institute of the Commerce ...

Scientists have created a clock so precise it could redefine the second. The strontium optical lattice clock is one of the most accurate timepieces ever made, capable of measuring seconds to 19 ...

PORTLAND, Ore. — A candidate to be the next-generation atomic clock is based on the heavy metal strontium and uses a laser lattice to suspend super-cooled atoms. The result was a 430-THz time ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The First Church of Christ, Scientist, and we’ve always been transparent about that. The church publishes the ...

Pairs of extremely cold strontium atoms have been used to make the most accurate molecular clock yet. It could be used to detect new forces and test some of Albert Einstein’s ideas about gravity.

Atomic clocks. They almost sound like something out of science fiction, or an experiment confined to some elite physics lab, but in reality, they’ve been around since the 1950s in one form or another.

Scientists have a set a new record in accurate timekeeping, creating an atomic clock that won’t lose or gain a second in 15 billion years — a time span greater than the estimated age of the Universe.

Scientists have developed a mercury-based optical lattice clock and measured the mercury clock frequency using the same group's recently developed strontium-based optical lattice clock as a reference.
