Speeding Up Electronics to Light Frequencies
December 5, 2012 — New results on the interaction of femto- and attosecond light pulses with a solid insulator hold promise for reaching electronic switching rates up to the petahertz ... > full storyMore: -
Switching With a Few Photons for Quantum Computing
December 5, 2012 — Quantum computing, where bits of information, or "qubits," are represented by the state of single atomic particles or photons of light, won't be of much use unless we can read the results. ... > full story -
Fire and Ice: Wildfires Darkening Greenland Snowpack, Increasing Melting
December 5, 2012 — Satellite observations have revealed the first direct evidence of smoke from Arctic wildfires drifting over the Greenland ice sheet, tarnishing the ice with soot and making it more likely to melt ... > full story -
Oceanography Student Uses Crashing Waves on Shorelines to Study Earth's Interior
December 5, 2012 — Scientists have long used the speed of seismic waves traveling through the Earth as a means of learning about the geologic structure beneath the Earth's surface, but the seismic waves they use have ... > full story -
Breakthrough in Augmented Reality Contact Lens
December 5, 2012 — Scientists have developed an innovative spherical curved LCD display, which can be embedded in contact lenses. The first step toward fully pixilated contact lens displays, this achievement has ... > full story -
Galaxy-Wide Echoes from the Past: VLT Observations Identify Very Rare New Kind of Galaxy
December 5, 2012 — A new galaxy class has been identified using observations from ESO’s Very Large Telescope (VLT), the Gemini South telescope, and the Canada-France-Hawaii Telescope (CFHT). Nicknamed ... > full story -
Crag Keeps the Light 'Fantastic' for Photoreceptors
December 4, 2012 — The ability of the eye of a fruit fly to respond to light depends on a delicate ballet that keeps the supply of light sensors called rhodopsin constant as photoreceptors turn on and off in response ... > full story -
New Optical Tweezers Trap Specimens Just a Few Nanometers Across
December 4, 2012 — A microscale technique known as optical trapping uses beams of light as tweezers to hold and manipulate tiny particles. Researchers have found a new way to trap particles smaller than 10 nanometers ... > full story -
Quantum Thermodynamics: A Better Understanding of How Atoms Soak Up Their Surroundings
December 4, 2012 — The best yet calculations of the effect of blackbody radiation on the wavefunction of ytterbium atoms, should help produce a better atomic ... > full story -
Dance of Quantum Tornadoes: Quantum Fluid Trapped on Top of Semiconductor Chip
December 4, 2012 — Tornado-like vortexes can be produced in bizarre fluids which are controlled by quantum mechanics, completely unlike normal liquids. New research demonstrates how massed ranks of these quantum ... > full story
