Platinum, Blue Light Combine to Combat Cancer
COVENTRY, England, Dec. 14, 2010 — Research led by the University of Warwick has found a way to use blue light to activate what could be a highly potent platinum-based cancer treatment. The team, also consisting of researchers from Ninewells Hospital Dundee and the University of Edinburgh, have found a new light-activated platinum-based compound that is up to 80 times more powerful than other platinum-based anticancer drugs and which can use “light activation” to kill cancer cells in a much more targeted way...
Doped Nanotubes Shine Brighter for Months
HOUSTON, Dec. 13, 2010 — Rice University researchers have discovered a simple way to make carbon nanotubes shine brighter. Bruce Weisman, a pioneer in nanotube spectroscopy and a researcher at Rice, found that adding tiny amounts of ozone to batches of single-walled...
Laser-made ‘Blast Badge’ Detects Explosion Intensity

TEDDINGTON, England, Dec. 9, 2010 — A European consortium comprising the National Physical Laboratory, ST Microelectronics, the University of Edinburgh and TU Delft has been involved in the development and application of the Megaframe Imager - an ultrafast camera capable of recording...
Light Absorption Boosted in Polymer Solar Cells
AMES, Iowa, Dec. 9, 2010 — Researchers from Iowa State University and the Ames Laboratory have developed a process capable of producing a thin and uniform light-absorbing layer on textured substrates that improves the efficiency of polymer solar cells by increasing light...
Materials Mystery in VO2 Cracked
OAK RIDGE, Tenn., Dec. 9, 2010 — A systematic study of phase changes in vanadium dioxide has solved a mystery that has puzzled scientists for decades, said researchers at the Department of Energy's (DoE) Oak Ridge National Laboratory (ORNL). Scientists have known that...
The Best of 2010
Dec 9, 2010 — We divided the most popular stories for 2010 by subject (Lasers, Optics and Imaging). These are the top five stories for the year in each category, as chosen by our readers.
Tiny Laser Show Lights Up Quantum Computing
WASHINGTON, Dec. 9, 2010 — A new laser-beam steering system that aims and focuses bursts of light onto single atoms for use in quantum computers has been demonstrated by collaborating researchers from Duke University and the University of Wisconsin-Madison. Described in the...
Europe Focuses on Bioimaging
BRUSSELS, Belgium, Dec. 8, 2010 — From microscopy to computer tomography (CT) scans, imaging plays an important role in biological and biomedical research, but obtaining high-quality images often requires advanced technology and expertise, and it can be costly. Euro-BioImaging, a...
Laser Technique Images Cancer Quickly and Clearly
CHAMPAIGN, Ill., Dec. 8, 2010 — The long, anxious wait for biopsy results could soon be over, thanks to a tissue-imaging technique developed at the University of Illinois. The research team demonstrated the novel microscopy technique, called nonlinear interferometric...
Material Senses, Terminates Damage
TEMPE, Ariz., Dec. 8, 2010 — A novel autonomous material that uses "shape-memory" polymers with an embedded fiber optic network may be able to not only sense damage in structural materials, its creators say, but even make repairs. The technology brings to mind the...
Four-fold Quantum Memory Demonstrated
PASADENA, Calif., Dec. 3, 2010 — Researchers at the California Institute of Technology (Caltech) have demonstrated quantum entanglement for a quantum state stored in four spatially distinct atomic memories. Their work also demonstrated a quantum interface between the atomic...
Glass Lens Arrays That Can Be Mass Produced
CHEMNITZ, Germany, Dec. 3, 2010 — Fraunhofer researchers have developed a process that allows lens arrays to be made from glass, making them able to be mass produced with extreme accuracy and could make more conveniently sized projectors possible. Projectors contain lenses...
3-D Laser Scanner Images Dinosaur Footprints
TRENTO, Italy, Dec. 2, 2010 — Throughout Trentino, Italy, many signs have been left by the dinosaur giants that trod the beaches and dominated the landscape millions of years ago, even before the valleys were formed. Icnologists – scientists who study the traces of animal...
Camera Images Invisible Blood
COLUMBIA, S.C., Dec. 2, 2010 — Chemists at the University of South Carolina have developed a camera that can image blood that is otherwise unseen by the naked eye, which could significantly impact forensic science. The new technology, called multimode imaging in the thermal...
A nanoscale look at how lithium batteries work
OAK RIDGE, Tenn. – A new type of scanning probe microscopy that can visualize electrochemical strain has enabled scientists to study the movement of ions in the cathode material of lithium-ion batteries, an approach that not only offers a better understanding of the...
Edible optical tags make a stand against counterfeit drugs
HONOLULU – The global pharmaceutical market is worth $800 billion annually, and approximately 10 percent of this is thought to be counterfeit. Most drug manufacturers employ printed codes or serial numbers, bar codes or hologram stickers on packaging to...
Hearing Is Believing
Dec 1, 2010 — Exhibitors at Frontiers in Optics (FiO) 2010, held Oct. 24-28 in Rochester, N.Y., were a pretty bullish bunch, sharing news about hirings, product innovations, facility expansions and other positive developments with the kind of optimism you have to...
Lighting the Path to Exascale Computing
YORKTOWN HEIGHTS, N.Y., Dec. 1, 2010 — New chip technology unveiled today by IBM integrates electrical and optical devices on the same piece of silicon, enabling computer chips to communicate using light pulses instead of electrical signals. The advance could bring exascale computers —...
Plasmonic antenna enhances spectroscopic studies
HOUSTON – The need for technologies that can detect molecules with high sensitivity is important in many fields. For applications ranging from industrial safety to homeland security, single-molecule sensitivity would be a highly valuable tool. Now an optical...
