Einstein-Podolsky-Rosen (EPR) quantum mechanics paradox

Extending Einstein's Spooky Actions for Use in Quantum Networks

January 26, 2015 4:18 pm | by Swinburne University of Technology | News | Comments

Researchers have demonstrated that the 1935 Einstein-Podolsky-Rosen quantum mechanics paradox may be extended to more than two optical systems, paving the way for exploration of larger quantum networks. The experiment also identified properties that may be useful in establishing secure quantum communication networks where shared sequences of numbers created between two parties need to be kept secret from a third party.

Magic Numbers of Quantum Matter Revealed by Cold Atoms

January 13, 2015 11:19 am | by Max Planck Institute of Quantum Optics | News | Comments

Topology, a branch of mathematics classifying geometric objects, has been exploited by physicists to predict and describe unusual quantum phases: the topological states of matter. These intriguing phases, generally accessible at very low temperature, exhibit unique conductivity properties, which are particularly robust against external perturbations, suggesting promising technological applications.

How many stars like our sun host planets like our Earth? NASA’s Kepler Space Telescope continuously monitored more than 150,000 stars beyond our solar system and, to date, has offered scientists an assortment of more than 4,000 candidate planets for further study — the 1,000th of which was recently verified.

Evocative New High-Def Views of Iconic Pillars of Creation

January 6, 2015 1:50 pm | by NASA | News | Comments

Although Hubble has taken many breathtaking images of the universe, one snapshot stands out from the rest: the iconic view of the so-called Pillars of Creation. The jaw-dropping 1995 photo revealed never-before-seen details of giant columns of cold gas bathed in the scorching UV light from a cluster of young, massive stars. In celebration of its 25th anniversary, Hubble has revisited the pillars, providing a sharper, wider view.

Perfect Storm Quenching Star Formation around Supermassive Black Hole

January 5, 2015 11:49 am | by National Radio Astronomy Observatory | News | Comments

High-energy jets powered by supermassive black holes can blast away a galaxy’s star-forming fuel, resulting in so-called "red and dead" galaxies: those brimming with ancient red stars yet containing little or no hydrogen gas to create new ones. However, astronomers using ALMA have discovered that black holes don’t have to be nearly so powerful to shut down star formation. They have detected a “perfect storm” of turbulence ...

Besides being a fundamental breakthrough, this discovery opens up the possibility of making devices which take the benefits of both light and matter.

Half-Light, Half-Matter Quantum Particles a Step toward Practical Quantum Computing Platforms

January 5, 2015 11:36 am | by City College of New York | News | Comments

Prospects of developing computing and communication technologies based on quantum properties of light and matter may have taken a major step forward. In a pioneering study, researchers were able to discover half-light, half-matter particles in atomically thin semiconductors consisting of a 2-D layer of molybdenum and sulfur atoms arranged similar to graphene.

NASA's planet-hunting Kepler spacecraft makes a comeback with the discovery of the first exoplanet found using its new mission — K2. The discovery was made when astronomers and engineers devised an ingenious way to repurpose Kepler for the K2 mission and continue its search of the cosmos for other worlds.

Engineers have invented a revolutionary coating material that can help cool buildings, even on sunny days, by radiating heat away from the buildings and sending it directly into space. The heart of the invention is an ultrathin, multilayered material that deals with light, both invisible and visible, in a new way.

Rocket Experiment Finds Surprising Cosmic Light

November 7, 2014 3:37 pm | by Kathy Svitil, Caltech | News | Comments

Using an experiment carried into space on a NASA suborbital rocket, astronomers have detected a diffuse cosmic glow that appears to represent more light than that produced by known galaxies in the universe. The researchers say the best explanation is that the cosmic light originates from stars that were stripped away from their parent galaxies and flung out into space as those galaxies collided and merged with other galaxies.

Researchers Project a Million Dazzlingly Sharp Images per Second on Curved Screens

October 27, 2014 5:38 am | by Fraunhofer | News | Comments

Projecting images on curved screens poses a dilemma. The sharper the image, the darker it is. A novel optical approach brings brightness and sharpness together for the first time on screens of any curvature — and additionally allows about 10,000-times faster projection rates. Researchers have applied a proven approach used with cameras.

Pesky Insect Inspires Practical Technology

In our vain struggle to kill flies, hands and swatters often come up lacking. This is due to no fault of our own, but rather to flies’ compound eyes. Arranged in a hexagonal, convex pattern, compound eyes consist of hundreds of optical units called ommatidia, which together bestow upon flies a nearly 360-degree field of vision. With this capability in mind, researchers are drawing on this structure to create miniature light-emitting devices

NASA's Voyager 2 spacecraft gave humanity its first glimpse of Neptune and its moon Triton in the summer of 1989. This picture of Neptune was produced from the last whole planet images taken through the green and orange filters on the Voyager 2 narrow angle camera. The images were taken on August  20, 1989, at a range of 4.4 million miles from the planet, 4 days and 20 hours before closest approach on August 25.

Astronomers announced that they have discovered a new type of planet — a rocky world weighing 17 times as much as Earth. Theorists believed such a world couldn't form because anything so hefty would grab hydrogen gas as it grew and become a Jupiter-like gas giant. This planet, though, is all solids and much bigger than previously discovered "super-Earths," making it a "mega-Earth."
