Particle physics: 'Honey, I shrunk the proton'

Scientists lobbed a bombshell into the world of sub-atomic theory on Wednesday by reporting that a primary building block of the visible Universe, the proton, is smaller than previously thought.

New shapes of photons open doors to advanced optical technologies

Researchers from the University of Twente in the Netherlands have gained important insights into photons, the elementary particles that make up light. They 'behave' in an amazingly greater variety than electrons surrounding ...

Neutron star's X-rays reveal 'photon metamorphosis'

A "beautiful effect" predicted by quantum electrodynamics (QED) can explain the puzzling first observations of polarized X-rays emitted by a magnetar—a neutron star featuring a powerful magnetic field, according to a Cornell ...

World's first optical atomic clock with highly charged ions

Highly charged ions are a common form of matter in the cosmos, where they are found, for example, in the sun or other stars. They are so called because they have lost many electrons and therefore have a high positive charge. ...
