New phenomenon could lead to novel types of lasers and sensors

There are several ways to "trap" a beam of light—usually with mirrors, other reflective surfaces, or high-tech materials such as photonic crystals. But now researchers at MIT have discovered a new method to trap light that ...

First-ever hyperspectral images of Earth's auroras

Hoping to expand our understanding of auroras and other fleeting atmospheric events, a team of space-weather researchers designed and built NORUSCA II, a new camera with unprecedented capabilities that can simultaneously ...

A quantum network of entangled atomic clocks

For the first time, scientists at the University of Oxford have been able to demonstrate a network of two entangled optical atomic clocks and show how the entanglement between the remote clocks can be used to improve their ...

Exotic quantum states: A new research approach

(PhysOrg.com) -- Theoretical physicists of the University of Innsbruck have formulated a new concept to engineer exotic, so-called topological states of matter in quantum mechanical many-body systems. They linked concepts ...

Image: A rare optical phenomenon spotted from orbit

Despite humankind's scientific prowess there are still many phenomena that defy explanation or a common agreement on why something happens. A 'glory' is a rare optical phenomenon that is mostly seen by pilots and mountain ...
