Light Squeezed Even Tighter
ADELAIDE, Australia, Nov. 13, 2009 – Scientists at the University of Adelaide proved that light can be squeezed into much tighter spaces than previously thought, thanks to new breakthroughs in the theoretical understanding of how light behaves at the nanoscale.
Laser Charts Green Protein
BERKELEY, Calif., Nov. 12, 2009 – Chemists at the University of California, Berkeley, discovered the secret to the structural changes that green fluorescent proteins (GFPs), used in biological studies, undergoe when they fluoresce.
Capsules Mock Photosynthesis
WURZBURG, Germany, Nov. 11, 2009 – German chemists report progress toward achieving artificial photosynthesis by packing thousands of similar molecules together to create a tiny capsule, then using a different kind of molecule as a light absorbing and emitting “filling.”
Finding Life in Martian Ice
PASADENA, Calif., Nov. 11, 2009 – Doctors with the Kinohi Institute and the University of Innsbruck in Austria devised an imaging technique to detect bacteria in frozen Antarctic lakes, with the ultimate goal of using the technology to identify microbial life in the extreme...
Senate Confirms 14th NIST Director
Nov 9, 2009 — The US Senate recently confirmed Dr. Patrick D. Gallagher as the 14th director of the Commerce Department’s National Institute of Standards and Technology (NIST) by unanimous consent. Gallagher has worked at NIST since 1993 as a scientist and...
Show Plans Laser Tribute
SAN FRANCISCO, Nov. 6, 2009 – Special events celebrating the 50th anniversary of the invention of the laser, including a “Cirque du Lasaire” reception, will mark SPIE Photonics West’s first year in San Francisco. The primary photonics technical symposium and exhibition in North...
3-D PV Cell Folds, Travels
ATLANTA, Nov. 5, 2009 – A new technology for growing nanostructures on optical fibers can be used to make 3-D photovoltaic systems foldable and portable, no longer confined to traditional locations such as rooftops.
Atom Imaged in Ultracold Gas
CAMBRIDGE, Mass., Nov. 5, 2009 – A high-resolution microscope was developed to image individual atoms in an ultracold quantum gas, marking the first time scientists detected single atoms in a crystalline structure made solely of light called a Bose Hubbard optical lattice.
Flir Delivers 100,000th IR Camera
Nov 5, 2009 — Camera maker Flir Systems Inc. of Wilsonville, Ore., said it will deliver its 100,000th commercial-use infrared camera this week. The Flir thermal imager, used for building inspection, was sold by Tucson, Ariz.-based Professional Equipment to Bob...
T-ray Tool Up and Running
AMES, Iowa, Nov. 5, 2009 – A new terahertz ray (T-ray) instrument installed at Iowa State University will allow scientists to take a unique look at material reliability, biofuel combustion, cancer screening, and other science and engineering research fields by reading...
Scope-Headed Rats Roam Free
TÜBINGEN, Germany, Nov. 4, 2009 – By building a tiny laser microscope small enough to mount on a rat’s head, researchers found a way to solve the puzzle of recording meaningful signals from brain cells that calculate perception and attention while the subject is in motion.
Flipping Photonic Shock Waves
COLLEGE PARK, Md., Nov. 3, 2009 – Speedy electrons or other charged particles can briefly outrun light in matter, producing a shock wave in the form of a cone of light known as Cerenkov radiation. For the first time, physicists have experimental verification of reversed Cerenkov...
Momentive Awarded $4.5M
ALBANY, N.Y., Nov. 3, 2009 – Momentive Performance Materials was awarded $4.5 million by the US Department of Energy to develop crystal growth technology aimed at accelerating low cost mass production of LED-based solid-state lighting.
T Cell Trigger: Sheer Force
BOSTON, Nov. 3, 2009 – An array of techniques including optical tweezers were used to find the "switch" that can swiftly change a T cell – a white blood cell that patrols the bloodstream and organs for signs of disease – from jury to executioner. Revealing this "missing...
Frequency Comb Shows Teeth
GAITHERSBURG, Md., & KONSTANZ, Germany, Nov. 2, 2009 – The first optical frequency comb that actually looks like a comb has been built and demonstrated by scientists in the US and Germany. The "teeth" of the new comb – a tool for precisely measuring different frequencies of visible light – are separated...
Diamonds sparkle in Raman application
SYDNEY, Australia – Researchers from Macquarie University and from the Defence Science and Technology Organisation (DSTO) in Edinburgh have developed a diamond Raman laser with 63.5 percent efficiency, taking diamond into the same conversion league as other Raman laser...
Dimple lens goes beyond the diffraction limit
LOS ANGELES – University of California scientists have created a new type of lens that can focus light down to a sub-100-nm spot. This record-breaking focusing power could open up new areas of research in biological sciences, nonlinear optics and near-field...
Going negative for a fast switch
LOS ALAMOS, N.M. – The days of high-speed, all-optical communication are literally a bit closer. Researchers at Los Alamos National Laboratory and at the University of New Mexico in Albuquerque have demonstrated a nanoscale negative-index metamaterial device that can...
Letters to the Editor
Nov 1, 2009 — The science sex gap I read Gary Boas’ article (“Understanding the ‘sex gap’ in science and math,” September, p. 45) with interest. I have been interested in science since I was a child. While in middle school, I remember my math instructor teaching...
Lighting the way to ultrafast microprocessors
MUNICH, Germany – The first milestone toward lightwave electronics has been achieved, thanks to a collaboration among physicists at Max Planck Institute of Quantum Optics in Garching, FOM Institute AMOLF (Institute for Atomic and Molecular Physics) in Amsterdam, the...
The art of SERS
CHICAGO – Surface-enhanced Raman spectroscopy (SERS) could help identify forged artworks. Researchers are using it to analyze paintings by 19th-century artist Mary Cassatt and the pastels she used to identify whether the materials were natural, synthetic or...
Photon Race Ends in Dead Heat
STANFORD, Calif., Oct. 29, 2009 – Racing across the universe for the last 7.3 billion years, two gamma-ray photons arrived at NASA’s orbiting Fermi Gamma-ray Space Telescope within nine-tenths of a second of one another. The dead-heat finish may stoke the fires of debate among...
PerkinElmer, Corning Partner
Oct 28, 2009 — PerkinElmer and Corning will partner to develop next-generation detection technologies for life sciences research, the businesses announced today. The agreement brings together Corning’s optical label-free detection technology with PerkinElmer’s...
Spintronics Go All-Electric
CINCINNATI, Oct. 28, 2009 – An innovative and novel way to control an electron's spin orientation using purely electrical means has been created for the first time. A multidisciplinary team of University of Cincinnati researchers created the all-electric spin electronics, or...
