A revolutionary achievement could pave the way for smaller, more efficient nuclear clocks. Last year, a research team led by UCLA achieved a milestone scientists had pursued for half a century. They s ...

Nuclear clocks are a technology researchers have been working toward for decades. New research in theoretical physics brings them closer to reality.

Atomic clocks are the most accurate timekeepers we have, losing only seconds across billions of years. But apparently that’s not accurate enough – nuclear clocks could steal their thunder, speeding up ...

Researchers demonstrated a new optical atomic clock that uses a single laser and doesn't require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks without ...

Next-generation atomic timekeeping techniques could push new frontiers in quantum physics, according to a new study. Atomic clocks are essential elements in GPS and other navigation systems — and a ...

EUROPE — Every clock in your house probably tells a slightly different time. Now picture those clocks as the most precise instruments humanity has ever built, so accurate that they wouldn’t lose or ...

Which atomic clocks are best? The first time zone, Greenwich Mean Time, was established in the late 1600s to assist sailors before the invention of the train and railway in the mid-1800s expanded the ...

Have you ever thought to use a clock to identify mineral deposits or concealed water resources within the Earth? An international team headed by astrophysicists Philippe Jetzer and Ruxandra Bondarescu ...

The reconciliation of general relativity and quantum mechanics is one of the biggest challenges in science, one that continues to elude us. Now, a new study by Anjun Chu and colleagues has examined ...

In 2008, a team of UCLA-led scientists proposed a scheme to use a laser to excite the nucleus of thorium atoms to realize extremely accurate, portable clocks. Last year, they realized this ...
