De-twinkle, de-twinkle little star
MARSEILLE, France, and GARCHING, Germany – Thanks to what is being billed as the world’s fastest and most sensitive astronomical camera, the European Southern Observatory (ESO)’s Very Large Telescope might be able to spot planets orbiting another star within a few years. Nonastronomical applications for the camera might lie in ophthalmology, combustion analysis or the study of chemical reactions. Jean-Luc Gach, an instrumentation engineer at Laboratoire d’Astrophysique de Marseille, was responsible for the development of the OCAM...
Letters to the Editor
Aug 1, 2009 — Solar coffee shop? I was intrigued by your articles on solar power in the May issue and have a question I hope you can help me with. I am a member of a Hewlett-Packard survey group that discusses topics such as various aspects of technology. One...
Radios broadcast into the ultraviolet
ADELPHI, Md. – Ultraviolet communications has been on the US military’s agenda since the 1960s, but only recently has the Army been able to perform small-scale, short-range, nonline-of-sight UV radio experiments that could lead to a novel communications...
Scientists are creating unusual type of laser from a strange material
NICE, France – Just what the heck is a random laser? Because lasers are supposed to produce coherent, linear beams of light, the notion of randomness in a laser beam seems at first to be an oxymoron. As in an ordinary laser, light in a random laser is amplified...
Solution to a hairy problem
TEDDINGTON, UK – A single strand of hair can reveal much about a person, especially if you know how to look. Proper investigation can determine diet as well as any drugs or poisons the person may have been exposed to, and the hair’s growth keeps this information in...
State Department addresses delays in obtaining visas
WASHINGTON – In the past year, researchers and students hoping to enter or re-enter the US have faced sometimes months-long delays in obtaining visas. Now, however, after a chorus of complaints from university groups and scientific organizations, the US...
Diffract-and-Destroy Imaging
BERKELEY, Calif., July 30, 2009 – A particle gun that fires liquid droplets less than a millionth of a meter in diameter, faster than hundreds of thousands of times a second, is poised to revolutionize biological imaging. Tested at Berkeley Lab’s Advanced Light Source and soon to be...
Viable Organic PV Realized
GAITHERSBURG, Md., July 30, 2009 – A new class of economically viable solar power cells – cheap, flexible and easy to make – has come a step closer to reality as a result of recent work at the National Institute of Standards and Technology, where scientists have deepened their...
Eye-Catching Vision Discovery
BALTIMORE, Md., July 28, 2009 – Researchers at the Johns Hopkins School of Medicine discovered in fish yet another type of cell that can sense light and contribute to vision.
Nanolaser Size Limit Broken
TEMPE, Ariz., July 28, 2009 -- An international research collaboration is reporting advances in breaking previous limitations on how small lasers can be made. The work opens up possibilities for using nanoscale lasers to significantly improve optical communications, single...
Beetle Bares Photonic Secrets
ATLANTA, July 24, 2009 – In discovering how the jeweled beetle, Chrysina gloriosa, creates its striking colors using a unique helical structure that reflects the light of two specific colors but of only one polarization, researchers may have unlocked photonic secrets with...
Cell Interactions Revealed
EUGENE, Ore., July 23, 2009 -- New findings that suggest putting lipids and other cell membrane components on manufactured surfaces to control like-charge attraction could lead to new classes of self-assembling materials for use in precision optics, nanotechnology, electronics...
Nanoscale Mass Spectrometer
PASADENA, Calif., July 23, 2009 – Using devices millionths of a meter in size, physicists at the California Institute of Technology developed a technique to determine the mass of a single molecule in real time.
Cell Phone Fluoromicroscopy
BERKELEY, Calif., July 22, 2009 – In what is being seen as a major step forward in taking clinical microscopy out of specialized labs and into the field, UC Berkeley researchers developed the CellScope, a cell phone turned into a fluorescent microscope.
Stimulus Funds Rice Facility
HOUSTON, July 22, 2009 – Rice University physics researchers will no longer have to wait until the dead of night to conduct experiments with instruments highly sensitive to vibration, thanks to $11.1 million in federal stimulus funding from the National Institute of...
'Drops' of Gold Burn Tumors
BARCELONA, Spain, July 21, 2009 – French researcher Romain Quidant proposes applying laser light to gold nanoparticles inserted into tumor cells, heating the particles to such a degree that the damaged cells would be completely burnt.
Materials Mimic Mechanics
BERKELEY, Calif., July 21, 2009 -- Astronomical phenomena such as black holes could be studied in a tabletop laboratory setting if the nascent field of artificial optical materials is combined with celestial mechanics, researchers say. “We have introduced a new class of specially...
Storing Sunlight for Soldiers
WRIGHT-PATTERSON AIR FORCE BASE, Ohio, & ARLINGTON, Va., July 21, 2009 -- New technologies for capturing sunlight and storing it as energy in flexible and wearable solar cells are being pursued by the Air Force Research Laboratory to help soldiers on the ground and those operating unmanned aerial vehicles.
Fine-tuning Ultracold Atoms
COLLEGE PARK, Md., July 20, 2009 – Scientists at MIT devised how to relay the successful storage of light in a form of quantum memory based on a cold-atom gas, while scientists in Brazil reported the controllable formation of quantum turbulence in an ultracold atom gas.
ILX Secures Development Grant
Jul 20, 2009 — ILX Lightwave Corp., located in Bozeman, Mont., has announced it has received a grant from the Montana Board of Research and Commercialization Technology for the development of high-accuracy optical power measurement of high-power laser diodes. The...
Electronic Metamaterial Made
BASEL, Switzerland, July 17, 2009 -- Physicists and chemists in Switzerland defied the belief that electrical resistance of a material can't be adjusted by developing thin films with controllable electronic properties. The discovery could have a big impact on future applications in...
OLED Efficiency Improved
DAEJEON, South Korea, July 17, 2009 -- A research team at KAIST (Korea Advanced Institute of Science and Technology) has discovered surface plasmon-enhanced spontaneous emission based on an organic LED (OLED), a finding expected to improve the device's energy consumption, KAIST officials...
Photonics Right Technology for Government to Invest in Next Generation
Jul 17, 2009 — The Institute of Microelectronics (IME), a research institute of Singapore’s Agency for Science, Technology and Research, and Bell Labs, Alcatel-Lucent’s research arm, recently signed a research collaboration agreement to jointly develop advanced...
Microvision Awarded $1M for Eyewear
Jul 13, 2009 — Microvision Inc. of Redmond, Wash., was awarded a $1 million subcontract by Lockheed Martin Corp last week as part of DARPA’s Urban Leader Tactical Response, Awareness & Visualization (ULTRA-Vis) program, an advanced technology development...
