Sound helps make a better optical clock
BRAUNSCHWEIG,Germany – Optical fibers are commonly used to transmit information and data via modulated light pulses. Now, however, three researchers at Physikalisch-Technische Bundesanstalt (PTB), working with optical frequencies rather than voice or data, are seeking to build a better optical clock. As signals travel along optical fibers, they become weaker because of optical attenuation and must be amplified. This presents a problem because the demand for extreme precision in transmitting the optical frequency...
US Distribution
Sep 1, 2010 — Precision Solutions of Stevenage, UK, has appointed Metrology Concepts LLC as its US distributor for the Interfire II family of infrared interferometers. Based in Rochester, N.Y., the latter company specializes in surface and wavefront measurement...
Using Reverse Engineering to Discover Patent Infringement
Sep 1, 2010 — Fundamental to building and executing any successful patent licensing program is the ability to find and prove evidence of infringement, often through reverse engineering methods. This article explores the role of reverse engineering in identifying...
Self-Cleaning Solar Cells
BOSTON, Aug. 30, 2010 — Large-scale solar installations are most efficient in desert regions where the sun is the strongest. Unfortunately those regions are also clouded with dust that gets into, and onto, everything — including solar panels. Now, based on technology...
‘Spintronics’ Breakthrough Promising for Computers
LAWRENCE, Kan. Aug, 27, 2010 — Using powerful lasers, researchers have now discovered a way to recognize currents of spinning electrons within a semiconductor. The discovery, dubbed “spintronics,” could lead the way to development of superior computers and...
Revealing How Cells Die
BUFFALO, N.Y., Aug. 27, 2010 — Apoptosis, or programmed cell death, is essential to normal development, healthy immune system function and cancer prevention. The process dramatically transforms cellular structures, but the limitations of conventional microscopy methods have kept...
Bright Boost for Fluorescent Probes
PITTSBURGH, Aug. 26, 2010 – Researchers from Carnegie Mellon University’s Molecular Biosensor and Imaging Center (MBIC) are turning up the brightness on a group of fluorescent probes called fluoromodules that are used to monitor biological activities of individual...
DNA Helps Chemists Build Artificial Nose
STANFORD, Calif., Aug. 25, 2010 — A new approach to building an artificial nose – using fluorescent compounds and DNA – could accelerate the use of sniffing sensors into the realm of mass production and widespread use, say Stanford University chemists. If their method...
Nova Explosion Reveals Gamma Rays
WASHINGTON, Aug. 25, 2010 — Using the Large Area Telescope (LAT) onboard NASA's Fermi Gamma-ray Space Telescope satellite, astronomers have detected gamma rays from a nova for the first time, a finding that surprises both observers and theorists. The discovery dispels the...
Ocean Optics LIBS IDs Fake Antiques
DUNEDIN, Fla., Aug. 25, 2010 — To separate authentic ceramic antiques from fakes, nationally recognized antiques appraiser Guan Haisen has employed an Ocean Optics LIBS system, with QE65000 spectrometer, to help him identify artificially aged ceramics and artifacts. Using...
Olympus Scanner Wins 2 Awards
HAMBURG, Germany, August 25, 2010 — Olympus won a pair of awards at the first European Scanner Contest, which took place May 25-29 in Berlin, running parallel to the 94th annual meeting of the German Society of Pathology. With categories in quality, mass scanning and cytology,...
Bright Future for Solar in India
Aug 24, 2010 — Hello friends, how have you been this past week? I'm back, and here's one more from the recently held Solarcon India 2010 in Hyderabad, India. Following the aggressive announcements made by the Ministry of New and Renewable Energy (MNRE),...
Multispectral Endoscopes on Horizon
BEVERLY HILLS, Calif., Aug. 24, 2010 – Spectral Molecular Imaging Inc. is to receive National Institutes of Health research funding via a collaboration with Omega Optical Inc. of Brattleboro, Vt. This effort will accelerate development of a new class of medical endoscopes enhanced with...
Pulsed Light Paces Embryonic Heart
CLEVELAND, Ohio, Aug. 23, 2010 — Scientists at Case Western Reserve University and Vanderbilt University found that pulsed light can pace contractions in an avian embryonic heart, with no apparent damage to the tissue. According to the scientists, this non-invasive device may...
Solar Process Gives Oil a Run for its Money
STANFORD, Calif., Aug. 23, 2010 — Stanford engineers have figured out how to simultaneously use the light and heat of the sun to generate electricity in a way that could make solar power production more than twice as efficient as existing methods and potentially cheap enough to...
The Quantum Leap: Researchers Explore the Clinical Potential of Quantum Dots
Aug 23, 2010 — Researchers have made tremendous progress in recent years in developing optical imaging for the study and management of disease. By taking advantage of the near-infrared window — the wavelength range where scattering and absorption of light...
Quantum Particles in Perfect Order
GARCHING, Germany, Aug. 20, 2010 — For the first time a team around Stefan Kuhr and Immanuel Bloch at Max Planck Institute of Quantum (MPQ) has now succeeded in observing — atom by atom, lattice site by lattice site — single-atom resolved images of a highly correlated...
Atom-Photon Pairs Key to Quantum Computers
MUNICH, Germany, Aug. 19, 2010 — In the quest for developing quantum computers that will be vastly superior to present-day computers, physicists have found that strong coupling of quantum bits with light quanta play a pivotal role. An electron microscopical picture of the...
Nanotubes Cover Ultradark Detector
GAITHERSBURG, Md., Aug. 19, 2010 — Harnessing darkness for practical use, researchers at NIST have developed a laser power detector coated with the world’s darkest material — a forest of carbon nanotubes that reflects almost no light across the visible and part of the...
Glass Target Measures Laser Weapon’s Power
ATLANTA, Aug. 18, 2010 — Technologies for using laser energy to destroy threats at a distance have been in development for many years. Today, these technologies — known as directed energy weapons — are maturing to the point of becoming deployable. High-energy...
Laser Technology Complements Radiation Therapy
DRESDEN, Germany, Aug. 17, 2010 — A new laser technology using accelerated ion beams to irradiate cancer cells while sparing more of the surrounding healthy tissue has been developed. Researchers at the OncoRay center and the Forschungszentrum Dresden-Rossendorf (FZD) research...
