Picture a clock ticking so steadily that it doesn’t lose a second, even after running for 1 billion years. Scientists are now closer than ever to realizing that level of timekeeping precision, new ...

Physicists have made one of the highest performance atomic clocks ever. ­­ Their instrument, known as an optical lattice atomic clock, can measure differences in time to a precision equivalent to ...

A team of researchers in Austria has recently demonstrated that the world’s first nuclear clock could help answer whether the fine-structure constant changes over time. The scientists from the Vienna ...

For the first lecture in the Fall Physics Colloquium Series, Chuankun Zhang, a graduate student from the University of Colorado Boulder's physics department and a researcher at JILA, delivered an ...

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 ...

The nucleus of an atom is now the modern version of sand flowing through an hourglass. Researchers have spent 15 years trying to increase accuracy in timekeeping. The U.S. standard currently relies on ...
