New window into quantum physics opened with superconductivity in LEDs Posted: 18 Mar 2014 11:05 AM PDT Physicists hae proposed a novel and efficient way to leverage the strange quantum physics phenomenon known as entanglement. The approach would involve combining light-emitting diodes with a superconductor to generate entangled photons and could open up a rich spectrum of new physics as well as devices for quantum technologies, including quantum computers and quantum communication.

Follow the ant trail for drug design: Ant behavior inspires software design Posted: 18 Mar 2014 08:20 AM PDT New drugs often fail because they cause undesirable side effects. Researchers have now developed simulation software that predicts the properties of active agents and virtually builds new ones. The software's search process is modeled after the behavior of ants. In order to allow the software to search for new composite agents, the research team uses an ant algorithm. Like an ant colony on the search for food, the algorithm screens through the molecular building blocks for components with the desired properties. Depending on the strength of the desirable and undesirable effects of the virtual products, the building blocks receive a 'grade'. In the ant world, this would equate to marking the trail to food with pheromones.
