Research & Technology News
UV-Activated Adhesive Treats Heart Defects
BOSTON, Jan. 13, 2014 — A bio-inspired, light-activated adhesive used to treat congenital heart defects could soon replace more invasive treatments such as sutures, new research indicates.
Powerful Exoplanet Camera Unveiled
LA SERENA, Chile, Jan. 9, 2014 — After nearly a decade of development, a powerful exoplanet camera that detects IR radiation to image and analyze planets from other solar systems is now operational.
X-ray Camera Has Image Stabilizer
BERLIN, Jan. 8, 2014 — Making a firm connection between an x-ray lens and the nanoscale object to be imaged improves the imaging of low-contrast or moving nano-objects and could lead to new insights into dynamic nanoscale processes, such as the fastest magnetic switching...
Lighting Up Brain Stops Liquored-Up Rats
BUFFALO, N.Y., Jan. 7, 2014 — Stimulating brain cells with light stops binge drinking in rodents, a new study finds. The results suggest the possibility of using optogenetics to treat substance abuse, neurological diseases and mental illnesses.
With Laser-Doping, Silicon Responds to IR Light
CAMBRIDGE, Mass., Jan. 7, 2014 — New IR imaging systems could be possible now that a new method has demonstrated that silicon is more responsive to IR light when laser-doped with one of its most dangerous impurities: gold. Detectors that are responsive to a broad range of IR light...
Chemistry Advance Paves Way for Printable Photonics
SINGAPORE, Jan. 6, 2014 — A method that turns certain chalcogenide compounds into high- quality, larger exfoliated flakes than currently available can be used in printable photonics and electronics. Dr. Zheng Jian, the first author of the paper, is shown demonstrating the...
Imaging Technology Could Unlock Mysteries of a Childhood Disease
ATLANTA, Jan. 2, 2014 — A superresolution imaging technique that allows the structure of a respiratory virus to be seen in living cells could help unlock the virus’s secrets, including how it enters cells and replicates, and why certain lung cells escape relatively...
Laser-Driven Nanobubbles Noninvasively Detect Malaria
HOUSTON, Jan. 2, 2014 — A noninvasive, laser scanner “vapor nanobubble” technology using no dyes or diagnostic chemicals can detect even a single malaria-infected cell among a million normal cells, with zero false-positive readings. The transdermal diagnostic...
US Research Spending Decline Driven By Industry
ANN ARBOR, Mich., Jan. 2, 2014 — A sharp drop in US spending on biomedical research has been driven almost entirely by reduced investments from industry, not the public sector, a new study finds. The US’s global share of biomedical research spending fell from 51 percent in...
Clark Telescope, 117, Closes for Facelift
FLAGSTAFF, Ariz., Dec. 31, 2013 — The Clark Telescope, a national treasure and site of notable discoveries such as the dwarf planet Pluto, is closing Jan. 1 after 117 years of constant use for a much-needed facelift, officials at Lowell Observatory said recently. The Clark’s...
‘Warping’ Compresses Big Data
LOS ANGELES, Dec. 30, 2013 — A physics-based data compression method outperforms existing technologies, such as JPEG, for images and could eventually be adopted for the capture and analysis of massive amounts of data in real time for communication, scientific research and...
Space Lasers Have ‘Bright Future’ in Communications
GREENBELT, Md., Dec. 30, 2013 — Neither wind, nor clouds, nor even atmospheric turbulence kept NASA’s Lunar Laser Communication Demonstration (LLCD) from its mission of providing error-free communications to ground stations from lunar orbit, NASA said recently in releasing...
Ultrathin PV Device is Highly Efficient
VALENCIA, Spain, & LAUSANNE, Switzerland, Dec. 30, 2013 — A thin film of perovskite sandwiched between two very thin organic semiconductors makes for a photovoltaic device with high power conversion efficiency, researchers have discovered. The thin-film photovoltaic device. A group led by Hendrik Bolink of...
Liquid Crystal ‘Flowers’ Into Lenses
PHILADELPHIA, Dec. 24, 2013 — A 3-D, liquid-crystal array shaped like a flower can be used as a lens similar to an insect’s compound eye, a team of material scientists, chemical engineers and physicists has found. The University of Pennsylvania team has been working to use...
Handheld OCT Device Catches Eye Disease Early
CAMBRIDGE, Mass., Dec. 23, 2013 — A handheld optical device that combines ultrahigh-speed 3-D imaging with a microelectromechanical systems (MEMS) scanning mirror could make early detection of certain eye diseases as easy as scanning a bar code. Photographs of the power grip style...
Technique Stabilizes Femtosecond Pulses
MOSCOW and LAUSANNE, Switzerland, Dec. 23, 2013 — A new technique that stabilizes femtosecond (fs) pulses generated in a microresonator could improve devices dependent on such pulses for applications in telecommunications, broadband spectroscopy and astronomy, among others. Last year, a team from...
UN Proclaims 2015 ‘International Year of Light’
PARIS, Dec. 23, 2013 — 2015 was proclaimed as the International Year of Light and Light-based Technologies (IYL 2015) during the 71st Plenary Meeting of the UN General Assembly 68th Session on Friday, a move lauded by a number of scientific societies and institutes. In...
Active Cloak Most Broadband to Date
AUSTIN, Texas, Dec. 19, 2013 — An active invisibility cloak — that is, one designed to work with an external power source — could significantly broaden the device’s operation bandwidth, moving its applications beyond camouflage. A team at the University of Texas...
Biophotonics Center Established at Adelaide
ADELAIDE, Australia, Dec. 19, 2013 — The University of Adelaide has been awarded AUD23 million (about $20 million) to establish a new Center of Excellence for Nanoscale BioPhotonics, the university announced this week. The goal of the center, funded by the Australian Research Council,...
Hubble Spots Vapor Venting Off Europa
GREENBELT, Md., Dec. 18, 2013 — NASA’s Hubble Space Telescope spectroscopically detected water vapor over the frigid south pole of Jupiter’s satellite Europa, providing the first strong evidence of water plumes erupting off the moon’s surface. This is an...
Photonics Gateway Launches
SOUTHAMPTON, England, Dec. 18, 2013 — The objective of ukphotonics.org, a new national website, is mapping the UK’s photonics activity to assist industry and academia with finding resources and collaborators. Hosted by the Engineering and Physical Sciences Research Council (EPSRC)...
THz Generator Has Highest Signal Quality
MADRID, Dec. 18, 2013 — A terahertz (THz) generator currently in development improves signal quality by 1 million times as compared with the best device of its kind available on the market, opening the technology to applications in biomedicine, transportation safety,...
