Brain Wave Control Could Improve Vision
URBANA, Ill., April 25, 2014 — The brain's preparation state -- whether it's focused or unconscious -- can have a significant impact on vision. Alpha waves, which characterize the brain’s electrical activity while at rest, can influence vision, a team of researchers from...
Femtosecond Lasers Control Chemical Reactions
VIENNA, April 25, 2014 — Hitting molecules with ultrafast lasers can affect electrons and trigger unaccustomed chemical reactions. Researchers at the Photonics Institute of the Vienna University of Technology, succeeded in directly inducing the splitting of hydrocarbons...
Plasmonic Probes Help Quantify Breast Cancer Gene Segments
WEST LAFAYETTE, Ind., April 25, 2014 — Hyperspectral imaging using plasmonic probes can ferret out a specific genetic telltale for breast cancer within individual cells, according to recent research from Purdue University. That genetic telltale is BRCA1, a tumor suppressor gene....
Simple Lens-Making Method Turns Phones into Dermascopes
CANBERRA, Austalia, April 25, 2014 — High-resolution silicon polymer lenses can be baked in conventional ovens and attached to smartphones to make an inexpensive microscope.
Ballato Recognized for Work on Optical Materials
CHARLESTON, S.C., April 23, 2014 — John Ballato is one of three people to receive the 2014 Governor's Award for Excellence in Scientific Research. This recognizes his work in optical materials science.
Dual-Catalyst Technique Allows Better Control of Molecules
MADISON, Wis., April 24, 2014 — Chemical reactions usually happen on their own terms. But now, researchers from the University of Wisconsin-Madison have discovered a way to create molecules with controlled chirality using sunlight as one of two catalysts.
Optogenetic Switch Now Works Both Ways: On and Off
STANFORD, Calif., April 24, 2014 — Since the beginning of optogenetics, the technique has been more effective at switching neurons on than off -- but not anymore. Building from Dr. Karl Deisseroth’s discovery about a decade ago of optogenetics — in which light-activated...
Blue LEDs Fail Color Differentiation Test
STATE COLLEGE, Pa., and FREMONT, Calif., April 23, 2014 — Not all shades of white are identical, although traditional and some LED lighting can make this difficult to prove. A study by researchers from Pennsylvania State University and Soraa Inc. focused on various combinations of light sources and white...
Noninvasive Imaging Method Promising for Skin Assessment
LEICESTER, England, April 23, 2014 — The complex biological process of skin aging can now be studied more extensively and efficiently, thanks to a new low-cost laser-based technique.
Stress Activates Light-Emitting Nanowires
ZURICH, April 23, 2014 — Stretching gallium arsenide nanowires makes them better light emitters, while compression makes them better light absorbers.
Electricity Changes Polymer’s Optical Properties
MILAN, WARSAW, Poland and DRESDEN, Germany, April 22, 2014 — A newly developed polymer is said to be the first of its kind to combine optical and electrical properties. This could mean new manufacturing possibilities for glass, polarization filters and sensors capable of detecting single molecules of a given...
Adaptive Optics Detect Early Diabetes Eye Damage
BLOOMINGTON, Ind., April 21, 2014 — Vision loss is a threat for millions of those suffering from diabetes. The earlier it can be detected, the sooner and potentially more effectively it can be treated.
Carbon Spaser Could Zap Cancer Cells
MELBOURNE, Australia, April 21, 2014 — A carbon-based nanolaser could be used to zap cancer cells, or enable electronics small and flexible enough to be printed on clothing.
Mid-IR Lens Incorporates Waste Sulfur
TUCSON, Ariz., April 21, 2014 — Thin, inexpensive plastic lenses for IR imaging devices can be manufactured from waste sulfur generated by refining fossil fuels.
Flir, ING to Create Aerial IR Inspection Methods
OTTAWA, Ontario, Canada April 18, 2014 — Flir Systems Canada is partnering with ING Robotic Aviation to develop robotic aircraft and new techniques for infrared inspections.
Long-Range 3-D Lidar May Enhance Military Operations
ESSEX, England, April 18, 2014 — Advancement of 3-D imaging and lidar technologies could spell significant enhancement for target identification, tracking and surveillance, namely in military operations. A team at Selex ES has developed a lidar system that uses a Geiger-mode (GM)...
Optical Society Names New Executive Editor
WASHINGTON, April 18, 2014 — Dr. Alison Taylor has joined The Optical Society (OSA) as executive editor.
Panels Redirect Sunlight into Shadowy Urban Areas
CAIRO, April 18, 2014 — Corrugated, translucent panels mounted on rooftops could be used to bend sunlight into places it normally doesn't reach.
Two-Stage Laser Could Make Rain, Lightning
UNION PARK, Fla., and TUCSON, Ariz., April 18, 2014 — Weather is beyond human control -- or is it? A team from the University of Central Florida (UCF) College of Optics & Photonics and the University of Arizona are developing a technique to trigger rain and lightning in clouds with a high-energy laser...
Exciton Movement Observed Directly
CAMBRIDGE, Mass., and NEW YORK, April 17, 2014 — For decades, scientists' understanding of excitons has been theoretical at best. However, a recent breakthrough has changed the game.
Hyperspectral Analysis Distinguishes Cells
SYDNEY, April 17, 2014 — Hyperspectral imaging (HSI) may soon expand its portfolio beyond mineralogy and food safety testing.
Laser Process Allows Precision Design of Nanospheres
HANNOVER, Germany, April 17, 2014 — A laser-based technique for creating light-scattering silicon nanospheres could have applications in medicine and sensor technology.
Technique Allows Whole-Brain Imaging with Single-Cell Resolution
SAITAMA, Japan, April 17, 2014 — Understanding the relationship between cellular phenomena and activity at the organism level has been difficult, particularly where the brain is concerned. Whole-brain imaging at single-cell resolution could help.
