Weak Laser Ignites Nanoparticles
GAINESVILLE, Fla., April 6, 2010 — Using a low-power laser engineering researchers have found they can ignite certain nanoparticles, a development they say opens the door to a wave of new technologies in health care, computing and automotive design. University of Florida’s Vijay Krishna, Nathanael Stevens, Ben Koopman and Brij Moudgil used lasers not much more intense than those found in laser pointers to light up, heat or ignite manufactured carbon molecules, known as fullerenes, whose soccer-ball-like shapes had...
Creating Bonds with Lasers
MUNICH, Germany, April 5, 2010 – In what was once considered a complicated and cost-intensive process, fiber-reinforced composites are now being crafted and bonded with lasers, eliminating the need for matting and resins. Fiber-reinforced thermosplastics, for example, are ideal...

INNSBRUCK, Austria, March 31, 2010 — Researchers in Austria have successfully realized a single-atom laser, an important step toward a fundamental understanding of laser operation in the few-atom limit, including syst...
1st Sub-10GHz Minispectrometer Made
TSUKUBA, Japan, March 30, 2010 — AiDi Corp. has developed a Fourier-transform, integrated-optic spatial heterodyne (FISH) spectrometer with an ability to correct interferometer defects using electrical data postprocessing at the highest level of resolution available — less than 10...
Microvision Completes New PicoP Design
REDMOND, Wash., March 30, 2010 — Microvision has completed the design of its ultraminiature PicoP laser projection display engine and has begun shipping evaluation samples to prospective customers, the company announced this week. The new device’s proprietary ASIC...
4-Molecule Nanowire Superconducts
ATHENS, Ohio, March 29, 2010 — A sheet of four pairs of molecules less than one nanometer wide can be superconducting, scientists have found. The Ohio University-led study provides the first evidence that nanoscale molecular superconducting wires can be fabricated, which could be...
Laser Light Controls X-Rays
BERKELEY, Calif., March 29, 2010 — By changing the material medium through which x-rays pass, scientists are using laser light to control x-ray beams. The team of scientists was led by Thornton E. Glover of Lawrence Berkeley National Laboratory’s Advanced Light Source (ALS),...
Nanogenerators Power New Sensors
ATLANTA, Ga., March 29, 2010 — By combining a new generation of piezoelectric nanogenerators with two types of nanowire sensors, researchers have created what are believed to be the first self-powered nanometer-scale sensing devices that draw power from the conversion of...
Resolving Individual Light Atoms
OAK RIDGE, Tenn., March 29, 2010 – Using the latest in aberration-corrected electron microscopy, researchers at the US Department of Energy’s Oak Ridge National Laboratory and their colleagues have obtained the first i...
Stretchable Electronics — Good for the Heart
EVANSTON, Ill., March 26, 2010 — Flexible and stretchable electronics that can map waves of electrical activity in the heart with better resolution and speed than that of conventional cardiac monitoring technology have been demonstrated. Researchers from Northwestern University,...
Laser Security Halts Hackers
TEL AVIV, Israel, March 25, 2010 – Computer hackers are getting smarter, which not only puts our national security at risk, but also compromises our personal and financial information. Now, a new invention is promis...
Light Twists Rigid Structures
ANN ARBOR, Mich., March 25, 2010 — While light has been known to affect matter on the molecular scale, it has not been observed causing such drastic mechanical twisting to larger particles – until now. After mor...
New Alloys Promise Better PV Cells, LEDs
TEMPE, Ariz., March 25, 2010 — A recent advance by Arizona State University researchers in developing nanowires could lead to more efficient photovoltaic cells for generating energy from sunlight and to better LEDs. Electrical engineers Cun-Zheng Ning and Alian Pan are...
Touchless Sensors on the Horizon
WÜRZBURG, Germany, March 25, 2010 — The cell phone is switched off but immediately springs into action at the point of a finger. It is not necessary to touch the display. This touchless control is made possible by a polymer sensor affixed to the phone which, like human skin, reacts to...
‘Microscope’ to Examine Glass Phase
ST. LOUIS, March 24, 2010 – The National Science Foundation has awarded $1.65 million to a project led by physicist Ken Kelton of Washington University in St. Louis to build an electrostatic levitation chambe...
Century-Old Calculations Prove True
HOUSTON, March 24, 2010 — In 1908, the German physicist Gustav Mie came up with an elegant set of equations to describe the interaction of electromagnetic waves with a spherical metal particle. The theory h...
Dark Matter Measures Age of Universe
DAVIS, Calif., March 23, 2010 — Astronomers from the United States and Europe have used a gravitational lens – a distant, light-bending clump of dark matter – to make a new estimate of the Hubble constant, which determines the size and age of the universe. The Hubble constant...
Film Scanner Captures Academy Award
WEITERSTADT, Germany, March 23, 2010 — Volker Massmann, Markus Hasenzahl, Klaus Anderle and Andreas Loew of the Germany-based company Digital Film Technology Holding GmbH won this year’s Academy Award for the company’s Spirit 4K/2K film scanner, which has become the industry standard for...
Latest Laser Developments in Berlin
BERLIN, Germany, March 23, 2010 — The focus is on semiconductor lasers at this year’s Laser Optics Berlin, held from March 22 to 24, 2010. The Ferdinand-Braun-Institut (FBH) will present the latest developments in laser technology at the event, as well as during the accompanying...
Raman/LIBS Aid Explosives Detection
MÁLAGA, Spain, March 23, 2010 — Using a novel hybrid sensor system, Spanish scientists have used both Raman and laser-induced breakdown spectroscopy (LIBS) simultaneously for the instant, remote standoff analysis...
Ross to Lead US-Scotland Photonics Project
GLASGOW, Scotland, March 23, 2010 – Iain Ross was named director at SU2P, a £2.4 million initiative between universities in Scotland and California which will enhance the economic impact of their research in photonic...
The Year in Stimulus Funding: The impact of the American Recovery and Reinvestment Act on biomedical research
Mar 23, 2010 — Dr. Francis S. Collins had, as they say, his work cut out for him. In early August 2009, the former head of the Human Genome Project was sworn in as the 16th director of the NIH and thus was charged with overseeing what President Obama would later...
