'Super atoms': Rydberg excitations form ordered structures in a quantum gas due to long-range interactions
(Phys.org)—Future computers are expected to use the laws of quantum physics to accomplish certain tasks in the blink of an eye that require decades for present-day computers. Physicists at the Max Planck ...
Tabletop laser-like device creates coherent multicolor beams of ultraviolet, T- and X-rays
For the first time, researchers have produced a coherent, laser-like, directed beam of light that simultaneously streams ultraviolet light, X-rays, and all wavelengths in between.
Chandra finds nearest pair of supermassive black holes
(PhysOrg.com) -- Astronomers have used NASA's Chandra X-ray Observatory to discover the first pair of supermassive black holes in a spiral galaxy similar to the Milky Way. At a distance of 160 million light ...
Nano antenna concentrates light: Intensity increases 1,000-fold
(PhysOrg.com) -- Everybody who's ever used a TV, radio or cell phone knows what an antenna does: It captures the aerial signals that make those devices practical. A lab at Rice University has built an antenna ...
Engineers find a way to win in laser performance by losing
Energy loss in optical systems, such as lasers, is a chief hindrance to their performance and efficiency, and it occurs on an ongoing, frustrating basis.
Astronomers measure nearby Universe's 'cosmic fog'
Researchers from the Laboratoire Leprince-Ringuet (CNRS/École Polytechnique) have carried out the first measurement of the intensity of the diffuse extragalactic background light in the nearby Universe, ...
Switching on a dime: How plants function in shade and light
Photosynthesis is the process by which plants convert energy from the sunlight into chemical energy in the form of sugars. These sugars are used by plants to grow and function, as well as food for animals ...

Hubble tells a tale of galactic collisions
(Phys.org) —When we look into the distant cosmos, the great majority of the objects we see are galaxies: immense gatherings of stars, planets, gas, dust, and dark matter, showing up in all kind of shapes. ...
Pink diamond 'behaviour' solved but colour still a mystery
UWA scientists have explained the photochromic behaviour of the pink diamond in an attempt to uncover why they possess their pink colouration.
