Algorithm Adds 3rd Dimension to Standard Video
CAMBRIDGE, Mass., Nov. 6, 2015 — By exploiting the graphics-rendering software that powers sports video games, researchers at the Massachusetts Institute of Technology (MIT) and the Qatar Computing Research Institute (QCRI) have developed a system that automatically converts 2D video of soccer games into a 3D version that can be played on commercial 3D televisions and other special-purpose displays. Today's video games generally store very detailed 3D maps of the virtual environment that players navigate. When the player
Lotus Leaf-Based Metamaterial Capable of Near-Total Light Absorption
TOKYO, Nov. 5, 2015 — An experimental biometamaterial fabricated using a lotus leaf as a template is capable of almost total absorption of light across the entire visible spectrum. Researchers from the Tokyo and Shibaura institutes of technology in Japan hypothesized...
Changing Frequency Speeds Phosphor Light Emission
PROVIDENCE, R.I., Nov. 4, 2015 — A technique for controlling light from phosphors at very high speeds could overcome the materials' slow optical performance, potentially enabling their use in optical communications. Phosphors are common light emitters used in light bulbs, LEDs and...

German Partnership to Modify Laser Welding for Shipbuilding
HANNOVER, Germany, Nov. 3, 2015 — The nonprofit research institute Lazer Zentrum Hannover eV (LZH) will work with industry partners and scientists to solve the challenges of joining steel and aluminum in maritime construction. To that end, the Laser Welding of Steel to Aluminum for...
Efficient Spectroscopic Imaging Demonstrated In Vivo
WEST LAFAYETTE, Ind., Nov. 2, 2015 — Although optical spectroscopy is routinely used study molecules in cell samples, it is currently not practical to perform in vivo. Now, a converted Raman spectroscopy system has been used to reveal the chemical composition of living tissues in...
Optogenetics Probes Create Their Own Light
ATLANTA, Nov. 2, 2015 — A novel class of proteins that create their own light could improve the versatility, scalability and practicality of optogenetics. Researchers at Emory University and the Georgia Institute of Technology have developed inhibitory luminopsins (short...
Study: NIR Light Effective in Treating Traumatic Brain Injury
DENVER, Nov. 2, 2015 — A longitudinal study has revealed near-infrared light to be an effective treatment for traumatic brain injury, a condition which brings over 2.5 million individuals to the emergency room each year. Carried out from 2011 to 2013, the study involved...
Lasercom System Also Measures Distance, Speed
GREENBELT, Md., Oct. 30, 2015 — Lasers used in space communications could also be used to make precise distance and speed measurements, benefitting spacecraft navigation. Called the Space Optical Communication and Navigation System, the breadboard technology is made up of...
Entanglement Effect Doubles Laser Beam Data Capacity
NEW YORK, Oct. 29, 2015 — Beams from ordinary laser pointers can be made to mimic the phenomenon of quantum entanglement, potentially doubling the amount of data they can carry. Physicists from The City College of New York, Herriot-Watt University in Scotland and Corning...
Spectroscopy Elucidates Solar Singlet Fission
CAMBRIDGE, England, Oct. 28, 2015 — Better understanding of singlet fission, an electrical process triggered by light in some materials, could enable solar cells twice as efficient as those used today. An international team led by researchers at the University of Cambridge, used...
Metamaterial Detects Circularly Polarized Light
NASHVILLE, Tenn., Oct. 27, 2015 — A metamaterial detector for circularly polarized light may open the door for development of small, portable sensors for applications from drug screening to communications and beyond. "Although it is largely invisible to human vision, the...
Dye Endures Repeated STED Irradiation
NAGOYA, Japan, Oct. 27, 2015 — Photostable fluorescent dye for superresolution microscopy could serve as a powerful tool to visualize biological events and structural details in living cells for prolonged periods. Researchers at Nagoya University have developed a new fluorescent...
Light-Sheet Microscope Pushes Resolution Limits
ASHBURN, Va., Oct. 26, 2015 — With resolution seven times greater than conventional light-sheet microscopes, a new device can capture cell-level 3D images across entire small organisms. Developed at the Howard Hughes Medical Institute's Janelia Research Campus, the microscope...
Attosecond Observations Probe Chemical Reactions
ZURICH, Oct. 23, 2015 — Laser pulses have been used to track the movements of electrons in molecules with a time resolution of 100 attoseconds — and even to alter their behavior. Demonstrated by researchers at the Swiss Federal Institute of Technology (ETH Zurich)...
Prisms, Masks Recreate Color Images from White Light
ZURICH, Oct. 23, 2015 — Full-color images can be projected using only two gray scale masks printed on transparencies affixed to a prism. A team from Disney Research Zurich demonstrated the effect and presented their findings recently at the Pacific Conference on Computer...
Spanish University to Honor Fiber Innovator Philip Russell
SANTANDER, Spain, Oct. 23, 2015 — Philip Russell, the inventor of photonic crystal fiber (PCF), will receive an honorary doctorate from Menéndez Pelayo International University next summer. Originally from Northern Ireland, Russell is director of the Max Planck Institute for...
Driver Creates Short, Powerful Pulses with LEDs
LIVERMORE, Calif., Oct. 22, 2015 — Providing high-brightness, rapidly pulsed, multicolor light, a new LED driver could displace more expensive lasers and other light sources in scientific, industrial and commercial uses. Researchers at Sandia National Laboratories have already used...
UCF to Explore Fiber Lasers under $5.9M Air Force Contract
ORLANDO, Fla., Oct. 21, 2015 — Researchers at the University of Central Florida (UCF) will develop new concepts for high-power fiber lasers under a five-year, $5.87 million contract from the U.S. Air Force. "We need to redesign the fiber from a simple communications fiber to one...
Quantitative Bioimaging Possible with Brightness-Equalized QDs
CHAMPAIGN, Ill., Oct. 20, 2015 — Quantum dots that emit light at the same brightness regardless of color could help bring fluorescence imaging into the realm of quantifiable data. Researchers at the University of Illinois at Urbana-Champaign engineered the quantum dots (QDs) to...
