How to Tell Real Scotch Whisky from Fake — Faster
GLASGOW, SCOTLAND, July 28, 2011 — Scientists at the University of Strathclyde have developed a method for distinguishing authentic from counterfeit Scotch whisky brands. The group used mid-IR spectrometry with attenuated total reflectance (ATR) to differentiate types of the drink...
Five Bucks and a Cell Phone Builds a Flow Cytometer
LOS ANGELES, July 27, 2011 — At the University of California, researchers from the Henry Samueli School of Engineering and Applied Science have developed a compact, lightweight and cost-effective optofluidic platform that integrates imaging cytometry and fluorescent microscopy...
Max Planck Physicist Honored for Attosecond Imaging
GIESSEN, Germany, July 27, 2011 — Matthias Kling, head of the attosecond imaging research group at the Max Planck Institute of Quantum Optics in Garching, Germany, is to receive this year’s Röntgen Prize from the Justus-Liebig-University in recognition of his...
Metamaterial Engineers Blackbody Radiation
CHESTNUT HILL, Mass., July 27, 2011 — Thermophotovoltaics may get a boost from a new designer metamaterial that can engineer emitted blackbody radiation with an efficiency beyond the natural limits imposed by the material's temperature. A blackbody object represents a theorized...
Laser Surgery Promising as Epilepsy Cure
HOUSTON, July 26, 2011 — To most parents, a child’s laughter is music to their ears, but when 8-year-old Keagan Dysart laughed, it meant he was having a gelastic seizure — a rare convulsion that caused him to laugh uncontrollably two to three times an hour. But...
Laser Therapy May Help Snake-Bitten Dogs
FORT COLLINS, Colo., July 26, 2011 — A new study is testing the effectiveness of laser light therapy as a low-cost alternative to antivenom for dogs that have been bitten by a rattlesnake. Dogs are commonly bit in the face, which may balloon from swelling. Rattlesnake venom...
Physicist Decides to Build Own Microscope inSTED
DENVER, July 26, 2011 — Physicist Stephanie Meyer is bringing new capabilities to the University of Colorado Denver Anschutz Medical Campus by building an advanced, superresolution microscope that can see some of the innermost workings of neurons and other cells. ...
Study Shows That Volvo Laser Sensor Prevents Crashes
ROCKLEIGH, N.J., July 26, 2011 — A midsize Volvo SUV equipped with collision-avoidance laser sensor technology gets into fewer low-speed crashes than comparable vehicles, according to a study conducted by two institutes concerned with highway safety.
First Optoelectronic 3-D Photonic Crystal Developed
CHAMPAIGN, Ill., July 25, 2011 — Using an epitaxial approach, the first optoelectronically active 3-D photonic crystal has been demonstrated – an advance that could open new avenues for solar cells, lasers, LEDs, metamaterials and more. "We’ve discovered a way to change...
Hitachi Electron Microscopy Products Centre Opens
EDMONTON, Alberta, Canada, July 21, 2011 — The official opening of the Hitachi Electron Microscopy Products Centre (HEMiC) is providing access to a uniquely configured transmission electron microscope, the first of its kind outside of Japan. Installed at the National Institute for...
Holographic Material Stores 20 Blu-rays on 1 Disc
NISKAYUNA, N.Y., July 20, 2011 — A new microholographic material can support data recording at the same speed as Blu-ray discs but with 10 times their typical storage capacity.
Unassuming Pluto Caught Harboring Another Moon
MOUNTAIN VIEW, Calif., July 21, 2011 — Astronomers using the Hubble Space Telescope have discovered a fourth moon orbiting the icy dwarf planet Pluto. The tiny satellite — temporarily designated P4 — was uncovered in a survey searching for rings around the dwarf planet. ...
Hot Tip Leads to Nifty Lithography Technique
ATLANTA, July 20, 2011 — Writing circuits and other tiny structures onto flexible plastic substrates could become more practical with a technique developed by researchers at Georgia Institute of Technology. The method could facilitate high-density, low-cost production of...
In Soil, Quantum Dots Spill Their Toxic Guts
BUFFALO, N.Y., July 20, 2011 — Within 15 days of entering soil, discarded cadmium and selenium quantum dots — even those with a protective shell — begin to leak toxic elements.
Optical Router Chip Is 100 Times Faster
VALENCIA, Spain, July 20, 2011 — An optical router chip that operates up to 100 times faster than those currently available is being called a scientific milestone in the field of optical communications by its international team of developers. The first monolithically...
THz Laser Power Detector Is a Piece of Cake
GAITHERSBURG, Md., July 20, 2011— Dense arrays of extra-long carbon nanotubes absorb nearly all light of long wavelengths and are promising coatings for prototype detectors intended to measure terahertz laser power. This type of radiation can penetrate numerous materials, making it...
Diamonds Aren’t Forever
SYDNEY, Australia, July 18, 2011 — Diamond may be the hardest naturally occurring material on Earth, but admire a sparkler in unfiltered sunlight and it will start shedding atoms. The discovery shows that diamond can be etched gently instead of through the more damaging process of...
