In a single experiment, physicists have measured the "excess" emission of high-energy gamma rays from more than a dozen heavy ...

Griffith University researchers are conducting an experiment at ANSTO that will test a revolutionary physics theory that time reversal symmetry-breaking by neutrinos might cause a time dilation at the ...

A photon enters a cloud of atoms and emerges on the other side. When physicists calculate how long the atoms remained excited ...

The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce ...

Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies required. The authors of a new, non-peer reviewed study detail how the a ...

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

To be useful, clocks need to be consistent. Imagine two spies who synchronize their watches; they rely on them agreeing days or months later, even if one of them must take a frigid hike through arctic ...

Yuri Ralchenko led one of the oldest teams at the National Institute of Standards and Technology. The fate of some experiments hangs in the air. Lost Science Yuri Ralchenko led one of the oldest teams ...

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.
