New Microscopy Technique Measures Properties of Biocircuits
PHILADELPHIA, June 10, 2011 — University of Pennsylvania researchers have developed a way to form biological molecules that can be directly integrated into electronic circuits, and they have developed a new microscopy technique that can measure the electrical properties of these and similar devices. The development involves bundles of peptide helices with a photoactive molecule inside. These artificial proteins are arranged on electrodes that transmit electrical charges between metallic and nonmetallic elements. When...
Rods Directly Imaged in Living Eye
WASHINGTON, June 10, 2011 — The tiny light-sensing cells known as rods have been clearly and directly imaged in the living eye for the first time. The innovation in adaptive optics will help doctors diagnose degenerative eye disorders sooner, leading to quicker intervention...
Stamping Out Low-Cost Nanodevices

Early Light Refines Brain’s Circuitry for Vision
PROVIDENCE, R.I., June 9, 2011 — Two new studies from Brown University on different species and using different techniques show how nascent animal brains use light to construct their central vision system. Creatures are not born hard-wired to see. Instead, they depend on...
NASA Awards Contracts to Boston Micromachines
CAMBRIDGE, Mass., June 9, 2011 — Boston Micromachines Corp. has been awarded $1.2 million by NASA to develop compact, ultralow-power, high-voltage multiplexed drive electronics suitable for integration with the company’s deformable mirrors in space-based wavefront control...
Plasmonics May Hold Key to All-Optical Chips
Jun 9, 2011 — A rapidly growing branch of physics promises all-optical computer chips and ultrafast computing speeds. Plasmonics, also called “light on a wire,” exploits the nanoscale interaction of light and metal and is a focus of research in the...
Two-Slit Interferometer Experiment Gets Makeover
TORONTO, June 9, 2011 — By applying a modern measurement technique to the historic two-slit interferometer experiment, scientists soon may be able to measure reality without distorting it. Quantum mechanics tells us that a tree falling in a forest with no one there...
First Images from VLT Survey Telescope Revealed
PARANAL, Chile, June 8, 2011 — With a startling portrait of the Swan Nebula, images acquired at the VLT Survey Telescope (VST) have begun to reveal the universe in more detail than ever before from a terrestrial site. The latest telescope to be added to the Paranal Observatory...
Global Fluorescence Map Offers New View Of Plants
GREENBELT, Md., June 8, 2011 — Groundbreaking maps of land-based plant fluorescence are revealing new information for the first time regarding vegetation spanning the entire globe. To date, most satellite-derived information related to the health of vegetation has come from...
Lasers Form 3-D Nanoparticle Crystals
ANN ARBOR, Mich., June 7, 2011 — Three-dimensional optically induced crystals have been created by manipulating thousands of microscopic plastic spheres trapped by laser-generated electric fields. The technique could someday be used to analyze the structure of materials of...
Upping the Anti: Antimatter Atoms Stored in Trap
BERKELEY, Calif., June 7, 2011 — A total of 309 antihydrogen atoms have been created and stored for as long as 1000 seconds (almost 17 min), with an indication of much longer storage times as well. The team involved in the collaboration said that adding lasers, which are essential...
Surface Plasmons Imaging Much Easier Than First Thought
LOUVAIN, Belgium, June 7, 2011 — An unusual observation turned into a breakthrough when researchers at Katholieke Universiteit Leuven discovered that surface plasmons leave imprints on the surface of the nanostructures. The result is expected to lead to a new type of...
Nanoantennas Used to Study Nonlinear Optical Effects
STUTTGART, Germany, June 6, 2011 — For the first time, researchers are using nanoantennas to focus laser light on oscillating nanoparticles to investigate ultrafast nonlinear optical effects. When a short laser pulse is focused on nanoparticles, they heat up very briefly and...
Solar Sheet Sucks Up Sunlight
COLUMBIA, Mo., June 6, 2011 — A flexible solar sheet that captures more than 90 percent of available light is slated to hit the consumer market within the next five years. Patrick Pinhero, an associate professor in the University of Missouri (MU) chemical engineering...
Supermicroscope Pinpoints Body’s Immunity “Switch”
SYDNEY, Australia, June 6, 2011 — Superresolution fluorescence microscopy has provided a glimpse into the inner workings of T cells, the front-line troops that alert our immune system to go on the defensive against germs and other invaders in our bloodstream. The discovery...
Flexible Films for Photovoltaics
FREISING, Germany, June 3, 2011 — Flexible plastic films are now being used to protect solar cells from the elements, a move that could significantly reduce the production cost of manufacturing a photovoltaic module. Instead of working with individual glass plates, the solar cells...
Cloaking Achieved in Visible Spectrum
KARLSRUHE, Germany, June 2, 2011 — The Karlsruhe invisibility cloak has been refined such that it is now effective in the visible spectral range. "Seeing something invisible with your own eyes is an exciting experience," say Joachim Fischer and Tolga Ergin, physicists and...
Near-IR Device Diagnoses Bladder Dysfunction
VANCOUVER, British Columbia, Canada, June 2, 2011 — A cell phone-size near-infrared device is as reliable as current invasive tests in determining bladder disease, according to a study by researchers at the University of British Columbia, Vancouver Coastal Health and the Child & Family Research...
Precision-Tinted Lenses Offer Migraine Relief
EAST LANSING, Mich., June 2, 2011 — Researchers have now shown why precision-tinted lenses reduce headaches for migraine sufferers, a finding that could help improve treatment options for patients battling the debilitating ailment. Jie Huang of Michigan State University’s...
“Sighted” wheelchair successfully test-driven
LULEÅ, Sweden – An electric wheelchair that uses a laser scanner to create a 3-D map of its surroundings and transfers the information to a haptic robot, enabling a visually impaired driver to navigate around obstacles, has been successfully tested. The...
Aircraft inspectors can turn off heaters
CAMBRIDGE, Mass. – Aircraft manufacturers soon may not need large heaters or traditional infrared thermography techniques to detect internal damage in planes and other objects, thanks to a simple handheld device and heat-sensitive camera devised by scientists at MIT....
Bilayered nanocrystals could bring cleaner energy
BERKELEY, Calif. – New bilayered nanocrystals made of metal-metal oxide that feature multiple catalytic sites on nanocrystal interfaces could mean big things for industrial catalysis and for clean green energy technologies such as artificial photosynthesis. For the...
Diamond aerogel could improve optics
LIVERMORE, Calif. – A nanocrystalline diamond aerogel could spell big improvements to optics for applications as large as telescopes or as small as eyeglass lenses. At Lawrence Livermore National Laboratory (LLNL), a laser-heated diamond anvil cell and a standard...
