‘Hidden Treasure’ Reveals Reflected Glory
MUNICH, Germany, Feb. 15, 2011 — Messier 78 is a fine example of a reflection nebula. The ultraviolet radiation from the stars that illuminate it is not intense enough to ionize the gas to make it glow — its dust particles simply reflect the starlight that falls on them. Despite this, Messier 78 can be observed easily with a small telescope because it is one of the brightest reflection nebulas in the sky. It lies about 1350 light-years away in the constellation of Orion and can be found northeast of the easternmost star...
It’s High ’Noon’ for Microwave Photons
SANTA BARBARA, Calif., Feb. 15, 2011 — An important milestone toward the realization of a large-scale quantum computer — and further demonstration of a new level of the quantum control of light — was accomplished by a team of scientists at UC Santa Barbara and China and Japan.
Jewel-toned Organic Phosphorescent Crystals
ANN ARBOR, Mich., Feb. 15, 2011 — A new class of pure organic compounds that glow in jewel tones could potentially lead to cheaper, more efficient and flexible display screens, among other applications. University of Michigan researcher Jinsang Kim and his colleagues have developed...
Weighing the Benefits of New Imaging Tech

Guide Star Sees Deep into Human Tissue
ST. LOUIS, Feb. 14, 2011 — Astronomers have a neat trick they sometimes use to compensate for the turbulence of the atmosphere that blurs images made by ground-based telescopes. They create an artificial star called a guide star and use its twinkling to compensate for the...
Plasmonics to Yield Thinner, Cheaper Solar Cells
STANFORD, Calif., Feb. 14, 2011 — A multidisciplinary team of Stanford engineers led by Mike McGehee, Yi Cui and Mark Brongersma, and joined by Michael Graetzel at the École Polytechnique Fédérale de Lausanne (EPFL) announced a new technology using plasmonics to...
Luciferase Aids Blood Clot Detection
NEW LONDON, Conn., Feb. 11, 2011 — The enzyme that makes fireflies glow is lighting up the scientific path toward a long-sought new medical imaging agent to better monitor treatment with heparin, the blood thinner that millions of people take to prevent or treat blood clots. In a...
NASA Extends LROC Contract
GREENBELT, Md., Feb. 11, 2011 — NASA has extended Phase E of its contract with Arizona State University for the Lunar Reconnaissance Orbiter Camera (LROC) instrument aboard the Lunar Reconnaissance Orbiter spacecraft. This cost-no-fee extension is for $11,368,735 and will be for a...
Breakthrough Reported in Visible Light-based ICs
COLLEGE PARK, Md., Feb. 10 , 2011 — University of Maryland researchers have made a breakthrough in the use of visible light for making tiny integrated circuits. Though their advance is probably at least a decade from commercial use, they say it could one day make it possible for...
High-efficiency PV Cells Developed in Spain
CATALUNYA, Spain, Feb. 10, 2011 — The Micro- and Nanotechnology Research Group of the Universitat Politècnica de Catalunya (UPC) has produced silicon photovoltaic cells with a conversion efficiency of 20.5 percent, the highest level achieved in Spain using this material. This...
Imaging, Genetics May Help ID Alzheimer's Risk
TORONTO, Feb. 9, 2011 — A new study from the Centre for Addiction and Mental Health (CAMH) has found evidence suggesting that a variation of a specific gene may play a role in late-onset Alzheimer's, the disease which accounts for over 90 percent of Alzheimer's cases. This...
BC Receives Funding for Novel Microscope
CHESTNUT HILL, Mass., Feb. 9, 2011 — Boston College has been awarded a $1 million grant from the W.M. Keck Foundation to help develop a new microscope that uses a light-guiding "metamedium" to create images that reveal micro- and macroscopic matter with significantly improved clarity....
Nanolasers Grown on Silicon Surface
BERKELEY, Calif., Feb. 9, 2011 — Nanolasers have been grown directly onto a silicon surface, an achievement that could lead to a new class of faster, more efficient microprocessors, as well as to powerful biochemical sensors that use optoelectronic chips. "Our results impact a...
BaySpec, Goodrich Deliver OCT Spectral Engine
SAN JOSE, Calif., Feb. 8, 2011 — BaySpec Inc. and Goodrich Corp,'s ISR Systems' Princeton team (formerly Sensors Unlimited Inc.) have announced that their recent collaboration has delivered a new optical coherence tomography (OCT) spectral engine with breakthrough speed, compact...
JDSU Optical Coating Improves Light Sensing in Consumer Electronics
MILPITAS, Calif., Feb. 8, 2011 — New microlithography, or patterning processes, were developed for JDSU’s optical coatings to improve light sensing intelligence in a variety of consumer electronic products, the company said. Coatings patterned with the new processes are...
Packed Atoms Boost Atomic Clock Performance
BOULDER, Colo., Feb. 7, 2011 — JILA scientists have eliminated collisions between atoms in an atomic clock by packing the atoms closer together. The discovery can boost the performance of experimental atomic clocks made of thousands or tens of thousands of neutral atoms trapped...
Sharp Images from a Tiny Cube
TOKYO, Feb. 7, 2011 — Microscopically small nanostructured arrays of lenses that can record or project amazingly sharp images in brilliant colors are being demonstrated by Fraunhofer research scientists at the nano tech 2011 trade show in Tokyo from February 16-18. ...
Si Alternative is Better Than Graphene
LAUSANNE, Switzerland, Feb. 7, 2011 — Smaller and more energy-efficient electronic chips could be made using molybdenite, a material developed in Switzerland. EPFL's Laboratory of Nanoscale Electronics and Structures (LANES) published a study showing that this material has distinct...
Laser Welding Process Fuses Plastics
AACHEN, Germany, Feb. 4, 2011 — A new laser welding process that emits light at the specific wavelengths at which plastic absorbs laser radiation makes it possible to fuse two transparent plastic components together for the first time. This advance could revolutionize...
FluxData Camera Heads to Space
ROCHESTER, N.Y., Feb. 3, 2011 — On Jan. 22, 2011, a multispectral imager built by FluxData Inc. was launched into space aboard the Japanese HTV-2 mission heading to the International Space Station (ISS). In the upcoming months after arrival, the imager, a key component of the...
Physicist Play ‘Hide-and-Seek’ with Photons
SANTA BARBARA, Calif., Feb. 3,2011 — Inspired by a trick known as "shell game," researchers at UC Santa Barbara have demonstrated the ability to hide and shuffle "quantum-mechanical peas" — microwave single photons — under and between three microwave resonators, or...
