Laser mastery narrows down sources of superconductivity Posted: 24 Feb 2013 11:29 AM PST Uncovering the mechanism behind high-temperature superconductivity -- a phenomenon with tremendous value to advances in energy efficiency and sustainability -- remains one of the greatest and most pressing puzzles in physics. Now, using precise laser pulses and atomically perfect 2-D materials, scientists have ruled out one possible source of HTS: Fleeting fluctuations called charge-density waves.

Graphene: A material that multiplies the power of light Posted: 24 Feb 2013 11:28 AM PST Researchers have demonstrated that graphene is able to convert a single photon that it absorbs into multiple electrons that could drive electric current -- a very promising discovery that makes graphene an important alternative material for light detection and harvesting technologies, now based on conventional semiconductors like silicon.

Quantum algorithm breakthrough: Performs a true calculation for the first time Posted: 24 Feb 2013 11:28 AM PST Scientists have demonstrated a quantum algorithm that performs a true calculation for the first time. Quantum algorithms could one day enable the design of new materials, pharmaceuticals or clean energy devices.

Taking the gamble out of DNA sequencing: How much can be learned in a large-scale experiment Posted: 24 Feb 2013 11:28 AM PST Scientists have developed an algorithm to predict how much can be learned in a large-scale DNA sequencing experiment -- with potential applications in every field of science.

Hubble sees a glowing jet from a young star Posted: 24 Feb 2013 05:21 AM PST The Hubble Space Telescope has captured a new image showing an object known as HH 151, a bright jet of glowing material trailed by an intricate, orange-hued plume of gas and dust.
