Now researchers have found a way to bypass the laws of quantum physics and create a vastly more stable and accurate atomic ...

In fusion, hydrogen isotopes are heated to extremely high temperatures until they form plasma – superheated, electrically ...

For the first time, a research team from the University of Cologne has observed the electron capture decay of technetium-98, ...

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 ...

A millimeter might not seem like much. But even a distance that small can alter the flow of time. “This is fantastic,” says theoretical physicist Marianna Safronova of the University of Delaware in ...

Even if you’re one of the most precise physicists on the planet — as University of Delaware Professor Marianna Safronova is — you still will need collaborators whose skills complement your own and ...

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.

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 ...
