Research & Technology News
LHC Smashes Speed Record
GENEVA, Nov. 30, 2009 – CERN’s Large Hadron Collider (LHC) outside Geneva became the world’s highest-energy particle accelerator by accelerating its twin beams of protons to an energy of 1.18 TeV, breaking the previous record of 0.98 TeV held by Fermi Lab’s Tevatron collider in Batavia, Ill., since 2001.
Multibeam Lasers Emit in IR
CAMBRIDGE, Mass., Nov. 30, 2009 – An international team of applied scientists demonstrated compact, multibeam and multiwavelength lasers emitting in the infrared. Typically, lasers emit a single light beam of a well-defined wavelength; with their multibeam abilities, the new lasers...
Nanowire Transistors Realized
WEST LAFAYETTE, Ind., Nov. 30, 2009 – A new generation of ultrasmall transistors and more powerful computer chips using semiconducting nanowires are closer to reality after researchers at IBM, Purdue and UCLA learned how to make them with layers of materials that are sharply defined at...
Telling Tom Turkey from Tina
DRESDEN, Germany, Nov. 25, 2009 – A novel approach to classifying the gender of 6-week-old turkey poults could save millions of male chicks from being killed shortly after birth, according to Dr. Gerald Steiner and his team from the Dresden University of Technology. Their use of...
Virtual Brain Surgery
BALTIMORE, Nov. 24, 2009 – Jin U. Kang, an electrical engineer at Johns Hopkins University, has spent years tinkering with lasers and optical fiber – studying what happens when light strikes matter. Now, he has built a tool to help brain surgeons locate and get a clear look...
LHC: The Beams are Back
GENEVA, Nov. 23, 2009 – Particle beams are once again circulating in the Large Hadron Collider (LHC), 14 months after an electrical failure caused serious damage to the world’s most powerful particle accelerator, which straddles the borders of France and Switzerland and is...
Photoswitch Paralyzes Animals
WASHINGTON, D.C., Nov. 23, 2009 – An internal on-off “switch” that paralyzes animals when exposed to a beam of ultraviolet light has been developed by a team of scientists in Canada. The animals stay paralyzed even when the light is turned off. When exposed to ordinary light, the...
Opportunity in the Indian RE sector
Nov 20, 2009 — Now then, let's look at one other opportunity story in the Indian renewable energy (RE) sector. This time, it is Sunil Jain, COO of Greeninfra Ltd., who said that the total RE capacity was only 9 percent of the total Indian capacity. The race to...
QDs Improve Medical Imaging
GAITHERSBURG, Md., Nov. 19, 2009 – Changes in a living cell that take place over a long period of time are difficult to scrutinize and require high-spatial-resolution imaging. But new research now makes it possible to analyze activities that occur over hours or even days inside...
Light Moves Nanostructures
ITHACA, N.Y., Nov. 18, 2009 – With a bit of leverage, Cornell researchers have used a very tiny beam of light with as little as 1 mW of power to move a silicon structure up to 12 nm. That’s enough to completely switch the optical properties of the structure from opaque to...
Complex Solar Surface Imaged
KATLENBURG-LINDAU, Germany, Nov. 17, 2009 – The most detailed images to date of the sun's grainy-looking surface were produced by the Sunrise balloon-borne telescope, a collaboration between the Max Planck Institute for Solar System Research (MPS) in Katlenburg-Lindau, Germany, and partners...
Mess-Free Graphene Growth
ITHACA, N.Y., Nov. 16, 2009 – A research team at Cornell University invented a simple, less expensive way to make graphene electrical devices by growing graphene -- one-atom-thick layers of carbon -- directly onto a silicon wafer.
Virtual Cloaking Unveiled
WASHINGTON, Nov. 16, 2009 – Researchers at Germany’s Karlsruhe Institute of Technology created a virtual visualization tool that shows what a partially or completely cloaked object would really look like. Even as an invisibility cloak hides an object, the cloak itself is...
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...
