Thousands of Cells Tracked Via Lensless Imaging
LOS ANGELES, Sept. 18, 2012 — A novel lensless computational imaging platform is being touted as a new way to observe and track large numbers of rapidly moving objects under a microscope, capturing precise motion paths in three dimensions. For the first time, the 3-D helical swimming patterns of more than 24,000 individual human sperm cells were directly recorded for as long as 20 seconds over wide fields of view and through large sample volumes. The work was done by a team at the UCLA Henry Samueli School of Engineerin...
Dark Energy Camera Records First Images
CERRO TOLOLO, Chile, Sept. 17, 2012 — After eight years of planning and construction, the most powerful sky-mapping machine ever created, the 570-megapixel Dark Energy Camera (DECam), achieved first light on Sept. 12. The camera was constructed at Fermi National Accelerator Laboratory...

Laser ‘Needle’ Could Take the Ouch Out of Shots
SEOUL, South Korea, Sept. 14, 2012 — Children (and even adults) who dread facing needles at the doctor’s office can find hope in a new laser-based system that shoots microscopic jets of drugs into the skin. To test the effectiveness of the drug delivery system, a special gel is...
University Spinoff to Advance Optical Integration
VALENCIA, Spain, Sept. 13, 2012 — A recent spinoff from the Technical University of Valencia is looking to further optical integration by increasing the complexity of chip designs and improving fabrication processes. Optical integration has followed the steps of microelectronic...
Laser Stability Improved by an Order of Magnitude
BOULDER, Colo., Sept. 12, 2012 — A laser so stable that its frequency varies by no more than two parts in 10,000 trillion represents an approach for constructing high-quality optical cavities that improve prior designs by more than an order of magnitude. The laser was developed and...
Muscles Get a ‘Light’ Workout
CAMBRIDGE, Mass., Sept. 12, 2012 — Genetically engineered muscle cells have been made to flex in response to light, a step toward using such light-sensitive tissue to build highly articulated robots.
Prism Awards Deadline Nears
PITTSFIELD, Mass., and BELLINGHAM, Wash., Sept. 12, 2012 — The entry deadline is fast approaching for the prestigious 2012-13 Prism Awards. The international competition, sponsored by Photonics Media and SPIE, the international society for optics and photonics, honors new technology and product inventions...
$1M Donation Supports Online Laser Eye Surgery Education
SAN FRANCISCO, Sept. 10, 2012 — Laser vision correction pioneer Dr. Charles R. Munnerlyn and his wife have donated $1 million to advance Web-based laser surgery education for ophthalmologists, the American Academy of Ophthalmology announced recently. The academy said the gift...
All-Optical Nanoswitch Promises Faster Computers
PHILADELPHIA, Sept. 10, 2012 — The first all-optical photonic switch made of cadmium sulfide nanowires has not only been produced but combined with others into a logic gate for on-chip information processing, which could help bring quantum computing a step closer.
Plasmon Wave Propagates for 80 µm with No Diffraction
CAMBRIDGE, Mass., Sept. 7, 2012 — A needle-like beam of light that propagates for an unprecedented distance of 80 µm without spreading could greatly reduce signal loss for on-chip optical systems. The cosine-Gauss plasmon beam, caused by quasiparticles called surface plasmons,...
Spectroscopy Optimizes Fluorescent Probes for DNA Study
HOUSTON, Sept. 7, 2012 — Time-resolved spectroscopy plus careful calculations can optimize photoluminescent probes for studying DNA, with results nearly twice as good as standard fluorescence spectroscopy for specific sequences, according to a new paper from Rice...
‘Magic Carpet’ Maps Mobility
MANCHESTER, England, Sept. 6, 2012 — Fiber optics could be the key to keeping people with mobility problems on their feet. A new "smart" carpet has an underlay of plastic optical fibers that bend when walked upon; it can immediately detect when someone has fallen and can help to...
A Silicon-Based Approach to Quantum Computing
BRISTOL, England, Sept. 6, 2012 — A new silicon-based approach to quantum computing could make the technology easier to mass-produce. Scientists at the University of Bristol’s Centre for Quantum Photonics, leading an international collaboration, made the leap from glass-based...
Optogenetics Pioneers Win Zülch
COLOGNE, Germany, Sept. 6, 2012 — Four scientists who initiated and were instrumental in promoting optogenetics will be recognized Sept. 7 with the K.J. Zülch Prize 2012 from the Gertrud Reemtsma Foundation. In announcing the prize recipients — Ernst Bamberg of Max Planck...
Lasers Map Hurricane Isaac Flooding
NEW ORLEANS, Sept. 5, 2012 — US Geological Survey scientists used a lidar technique called terrestrial lidar over the weekend to map urban flooding caused by Hurricane Isaac. “T-lidar” will enable them to collect highly detailed information in select population areas in...
Spinach Power Boosts Si Solar Cells
NASHVILLE, Tenn., Sept. 5, 2012 — Popeye’s not the only one who can get a big power boost from spinach: Combining the vegetable’s photosynthetic protein with silicon produces significantly higher current levels than can be achieved by other such "biohybrid" cells...
Record Laser Pulse the Key to Hidden Quantum World
ORLANDO, Fla., Sept. 4, 2012 — The most significant breakthrough in the laser pulse field in four years provides scientists with a new tool to watch quantum mechanics in action — a world hidden from view until now. The work was also accomplished without using specialized...
Wireless Optical Networks Eyed for Vehicles
CONVENTRY, England, Sept. 4, 2012 — LED-based wireless optical networks in vehicles could significantly cut the weight of wiring under the hood, not only saving on fuel, but also allowing passengers to tap into visible or infrared spectrum bands in overhead lighting to watch movies or...
“Spintronic” OLED promises brighter displays
SALT LAKE CITY – A new “spintronic” OLED that produces an orange color holds promise for brighter, cheaper and more environmentally friendly LEDs than the ones typically used in television and computer displays, lighting and electronic devices. ...
