GAITHERSBURG, Md., June 18, 2012 — Software that calibrates hyperspectral imagers could ensure that their performance is optimized for medical applications, such as determining diseased tissue margins during surgery.
Attopulses of Light Generated on Glass
GARCHING, Germany, June 15, 2012 — A new method that generates ultrashort attosecond bursts of light on a glass target will permit the highest resolution to date.
Frequency Combs Advance Biomedicine
DENVER, June 15, 2012 — Laser frequency combs, first a curiosity but now a practical research tool, are moving beyond physics and optics to advance biomedicine by helping evalulate a novel instrument that kills harmful bacteria without liquid chemicals or high...
NASA’s Black-Hole Hunter Begins Mission
WASHINGTON, June 15, 2012 — The first telescope capable of focusing high-energy x-rays to image black holes and other celestial phenomena in never-before-seen ways was launched Wednesday, NASA officials said.
Nanoplasmonics Drives Technique for Next-Gen Lenses
SAN DIEGO, June 14, 2012 — A new technique that enables metallic cube-shaped nanocrystals to spontaneously self-assemble into larger, complex materials could pave the way for the next generation of antennas and lenses.
Relocating LEDs Enhances Efficiency
GUANGZHOU, China, June 14, 2012 — Gallium nitride (GaN) LEDs grown on a layer of silicon were successfully transferred to a layer of copper, enhancing efficiency by 122 percent, say Chinese researchers.
Dual-Purpose Neural Probe Enables New Capabilities
HOUSTON, June 13, 2012 — A new device that combines light delivery with a tetrode into a single neural probe may offer new ways of studying small clusters of brain cells.
ESO Approves Extremely Large Telescope
GARCHING, Germany, June 13, 2012 — The world’s biggest eye in the sky is a step closer to becoming reality. Plans for the European Extremely Large Telescope (E-ELT) were approved by the ESO Council pending confirmation of four ad referendum votes. The project is set to commence early...
Laser Theoretically Forms Corkscrews of Light
HERTFORDSHIRE, England, June 12, 2012 — Laser beams formed into dark helices, or corkscrews of light, have considerable advantages over their commonly considered bright cousins for applications such as lithography, particle trapping and particle transport, a theoretical investigation...
Largest Flexible Color OLED Display Produced
TEMPE, Ariz., June 11, 2012 — A prototype of the largest flexible color organic LED display was developed using advanced mixed-oxide thin-film transistors.
Lidar Reveals Ruins of Lost City
HOUSTON, June 11, 2012 — An airborne laser mapping project involving billions of laser shots has unveiled archaeological ruins in a remote region of Honduras that may contain the legendary lost city of Ciudad Blanca, or White City.
Studies Boost Quantum Memory Storage
BURNABY, British Columbia, CAMBRIDGE, Mass., GARCHING, Germany, & ASCOT, England, June 11, 2012 — Two independent studies have stretched the manipulation times of quantum bits (qubits) of information, and these longer lifetimes suggest that spin-based qubit systems are a feasible foundation for realizing a practical quantum computer. Despite the...
Nondistorting Mirror Receives Patent
PHILADELPHIA, June 8, 2012 — A subtly curved side mirror that eliminates dangerous blind spots for drivers has been patented.
Smallest Possible Five-Ringed Structure Created
LONDON, June 7, 2012 — In honor of the upcoming Summer Olympics, the smallest possible five-ringed structure – just 1.2 nm in width and about 100,000 times thinner than a human hair – has been created and imaged using a combination of synthetic chemistry and...
Tabletop Device Creates All Wavelengths in 1 Beam
ARLINGTON, Va., June 7, 2012 — More than 5000 low-energy photons have been converted into one high-energy x-ray photon. The coherent, directed light beam was generated for the first time using a device small enough to fit on a single laboratory table.
Exotic Particles, Chilled and Trapped, Form Giant Matter Wave
SAN DIEGO, June 6, 2012 — Excitons were trapped and cooled so effectively that they condensed and cohered to form a giant matter wave, a feat that will enable scientists to study the physical properties of excitons, which exist only fleetingly yet offer promising...
2013 Prism Awards Open for Entries
PITTSFIELD, Mass. – Photonics industry heavyweights and budding spinoffs alike are poised to compete for this year’s Prism Awards for Photonics Innovation. Dubbed the “Oscars of Photonics,” the Prism Awards is an international competition that...
From Embryo to Larva: Microscope Observes Fly Growth
HEIDELBERG, Germany, June 5, 2012 — For the first time, a two-and-a-half-hour-old fruit fly embryo was filmed in 3 D using a new microscope that rapidly images biological processes in thick samples at unprecedented detail.
FEL Reveals Detailed Architecture of Proteins
HAMBURG, Germany, June 4, 2012 — A novel free-electron laser (FEL) x-ray technique that obtains high-resolution structural insight into biomolecules can deliver structural data that could be used to design tailor-made medications.
Laser ARPES Helps Explain Superconductivity
BERKELEY, Calif., June 4, 2012 — A new ultrafast laser angle-resolved photoemission spectroscopy (ARPES) technique may soon help scientists realize some of the biggest obstacles to the electronic states of high-temperatures superconductors so that they may one day put these...
Planet-Hunting with Laser Rulers
GARCHING, Germany, June 1, 2012 — Astronomers searching for extrasolar planets may be a step closer to finding other Earthlike places in the universe around sunlike stars, thanks to a new tool that promises to increase the accuracy of planet-hunting devices by tenfold.
Cold atoms in an optical lattice simulate graphene
ZURICH – The creation of a tunable system of ultracold atoms within a honeycomblike structure similar to that found in graphene may help identify the electronic properties of materials that have yet to be discovered. Professor Tilman Esslinger of the...
