Laser probes pollution particles
Sep 1, 2012 — The most detailed images to date of airborne soot particles, generated with x-rays from the Linac Coherent Light Source (LCLS), will have important implications for climate modeling and human health, among other areas. Aerosol particles such as soot are significant in fields ranging from toxicology to climate science. Despite their importance, their properties are difficult to measure: Visible light does not provide adequate resolution, x-ray sources are typically not bright enough to...
Olympus Licenses Pathology Patents to Zeiss
Sep 1, 2012 — Olympus America Inc. of Center Valley, Pa., and Carl Zeiss Microscopy GmbH of Jena, Germany, have signed a nonexclusive worldwide licensing agreement allowing the German company to access Olympus’ portfolio of digital pathology and virtual...
Robotic camera mimics eye movement
ATLANTA – Piezoelectric materials that allow a robot’s camera eye to replicate the muscle motion of a human eye could help make safer, more effective robotic tools for MRI-guided surgery and robotic rehabilitation. The biologically inspired...
Limits of Plasmonic Enhancement Measured
DURHAM, N.C., & LONDON, Aug. 31, 2012 — Photonic interactions have been measured on the scale of a single atom for the first time. The ability to quantify the unique properties of light gives physicists a "road map" for precisely controlling its scattering in metal-based devices such as...
Moore Named Interim CEO of Iridex
MOUNTAIN VIEW, Calif., Aug. 30, 2012 — Medical device industry veteran William M. Moore will serve as interim president and CEO of laser-based medical systems maker Iridex. The appointment, announced this week, takes effect immediately.
Laser Surgery Pioneer Isaac Kaplan Dies
TEL AVIV, Israel, Aug. 29, 2012 — Professor Isaac Kaplan, a pioneer in the creation of the first carbon dioxide laser for general surgery and founder of the International Society for Laser Surgery and Medicine, has died. He was 93. Kaplan was professor emeritus of surgery and past...
Survey Says: O&P Community Mostly Content
BELLINGHAM, Wash., Aug. 29, 2012 — More than 80 percent of optics and photonics professionals who responded to a new survey said they enjoy their work and find it meaningful. The survey, the largest such international study of the industry, was conducted last spring by SPIE. "Results...
Merging Microscopy Methods Sharpens Brain Imaging
SESTO FIORENTINO, Italy, Aug. 28, 2012 — Technology that combines the best features of two microscopy methods yields images 100 percent sharper than those acquired through conventional light-sheet-based microscopy (LSM).
Microscope Addresses the Need for Speed
LEICESTER, England, Aug. 28, 2012 — A technology used in projectors can create a high-resolution image 100 times faster than conventional microscopy equipment, which can be too slow to clearly document speedy biological processes.
3-D Photografting Grows Bio Tissue
VIENNA, Aug. 27, 2012 — Photografting, a new form of three-dimensional printing that uses lasers to precisely attach molecules at specific places in a material, could soon make it possible to grow biological tissue or to create microsensors.
Supersensor Detects Single Virus Samples
NEW YORK, Aug. 27, 2012 — Exploiting an odd behavior of light boosts a biosensor platform’s sensitivity by nearly 70 times, allowing it to detect a single sample of the smallest known viruses.
Nanocrystal Films Promising for Photonic Circuits
CAMBRIDGE, Mass., Aug. 24, 2012 — A new process for patterning defect-free nanocrystal films with nanometer precision could advance photonic devices and basic physics research.
Optical Microscope Exceeds Diffraction Limit
AMSTERDAM, LONDON and BARCELONA, Spain, Aug. 22, 2012 — An optical microscope that combines electronic excitation and optical detection has broken Abbe’s diffraction limit. The nanoscale imaging method offers insight into how light and complex photonic materials interact and could lead to enhanced...
Guidelines Needed to Advance Diagnostic Accuracy
NEW YORK, Aug. 21, 2012 — Tiny mechanical microscopes — those that can see inside single living cells — increasingly are being used to diagnose illness in hard-to-reach areas of the body, but specialists say they need improved, standardized guidelines to advance...
Laser’s Cousin Comes In from the Cold
TEDDINGTON, England, Aug. 21, 2012 — A new solid-state maser capable of operating at room temperature could enable more sensitive medical instruments, improved chemical sensors, and better radio telescopes, among other applications.
Method ‘Tags and Tracks’ DNA Looping
DALLAS, Aug. 20, 2012 — A “tag and track” method using fluorescent molecules not only sheds light on how DNA loops form, but also might be adapted to screen drugs for effectiveness against certain viruses that shuffle genetic material, such as HIV.
Technique Expands Range of X-ray Research
ARGONNE, Ill., Aug. 20, 2012 — A new technique takes much of the “guesswork” out of x-ray imaging by combining high-resolution and 3-D viewing, allowing the surface of materials to be viewed nondestructively for the first time. The findings expand the range of x-ray research...
Color-Coded Markers Diagnose Disease Through Eyes
SAN DIEGO, Aug. 17, 2012 — New fluorescent probes that change color when they encounter brain disease markers found in the eye could offer a simpler way to identify neurodegenerative disease and distinguish between closely related disorders such as Parkinson’s, Alzheimer’s...
Glowing Molecules Turn On, Off to Visualize Cell Activity
CORAL GABLES, Fla., Aug. 17, 2012 — Using UV light to switch fluorescent molecules on and off in aqueous environments could help scientists develop better fluorescent probes for biomedical research.
Carl Zeiss Meditec Revenue Climbs Steadily
JENA, Germany, Aug. 16, 2012 — Carl Zeiss Meditec AG saw its revenue climb to €630.8 million over the first nine months of its 2011-12 financial year, a year-over year increase of 13.6 percent.
The (Sometimes Sordid) History of X-ray Vision, Part 1
Aug 10, 2012 — The implementation of whole-body scanners in airport security lines and news about the possibility of using smartphones to detect terahertz radiation have inevitably led to talk about x-ray vision. We often use this as shorthand for “the...
Hamilton Thorne Laser Granted European Patent
BEVERLY, Mass., and TORONTO, Aug. 3, 2012 — The modular objective assembly in Hamilton Thorne Ltd.’s Lykos and Xyrcos lasers will be granted a patent, according to a notice of intention the company received from the European Patent Office. Upon approval, the patent can be filed in more than...
Making Microscale Wrinkles
CAMBRIDGE, Mass., Aug. 3, 2012 — A new method of creating microscale wrinkled surfaces with precise sizes and patterns can be compared to the way raisin skins dry, becoming stiff and wrinkly as the pulp inside dries out.
Biolase Responds to Patent Suit
Aug 1, 2012 — CAO Group Inc. of West Jordan, Utah, has filed a lawsuit against dental laser company Biolase Technology Inc. of Irvine, Calif., in US District Court, alleging patent infringement involving Biolase’s ezlase diode laser, the California company...
FEL reveals protein architecture in detail
HAMBURG, Germany – A free-electron laser (FEL) x-ray technique that obtains high-resolution structural insight into biomolecules to deliver structural data eventually could be used to design tailor-made medications. Understanding the structure of biomolecules is...
