Virtual Brain Surgery
BALTIMORE, Nov. 24, 2009 – Jin U. Kang, an electrical engineer at Johns Hopkins University, has spent years tinkering with lasers and optical fiber – studying what happens when light strikes matter. Now, he has built a tool to help brain surgeons locate and get a clear look at cancerous tissue. In some cases, this device could eliminate the need to cut into the brain for a traditional biopsy, a procedure that can pose risks to the patient.
Michelson Wins Grant for OCTs
Nov 23, 2009 — Michelson Diagnostics Ltd., the London-based manufacturer of optical coherence tomography (OCT) products, has been awarded a grant worth more than $41,500 from the UK government’s Technology Strategy Board (TSB). The funds are for a study into the...
Photoswitch Paralyzes Animals
WASHINGTON, D.C., Nov. 23, 2009 – An internal on-off “switch” that paralyzes animals when exposed to a beam of ultraviolet light has been developed by a team of scientists in Canada. The animals stay paralyzed even when the light is turned off. When exposed to ordinary light, the...
QDs Improve Medical Imaging
GAITHERSBURG, Md., Nov. 19, 2009 – Changes in a living cell that take place over a long period of time are difficult to scrutinize and require high-spatial-resolution imaging. But new research now makes it possible to analyze activities that occur over hours or even days inside...
Light Moves Nanostructures
ITHACA, N.Y., Nov. 18, 2009 – With a bit of leverage, Cornell researchers have used a very tiny beam of light with as little as 1 mW of power to move a silicon structure up to 12 nm. That’s enough to completely switch the optical properties of the structure from opaque to...
Gulf Fiberoptics Adds New Div.
Nov 16, 2009 — Gulf Fiberoptics, an Oldsmar, Fla.-based manufacturer of fiber optic products for the medical, industrial and visual illumination markets, has announced that it is adding a new photonics division. The division’s business development will be headed...
Light Squeezed Even Tighter
ADELAIDE, Australia, Nov. 13, 2009 – Scientists at the University of Adelaide proved that light can be squeezed into much tighter spaces than previously thought, thanks to new breakthroughs in the theoretical understanding of how light behaves at the nanoscale.
Laser Charts Green Protein
BERKELEY, Calif., Nov. 12, 2009 – Chemists at the University of California, Berkeley, discovered the secret to the structural changes that green fluorescent proteins (GFPs), used in biological studies, undergoe when they fluoresce.
Capsules Mock Photosynthesis
WURZBURG, Germany, Nov. 11, 2009 – German chemists report progress toward achieving artificial photosynthesis by packing thousands of similar molecules together to create a tiny capsule, then using a different kind of molecule as a light absorbing and emitting “filling.”
Finding Life in Martian Ice
PASADENA, Calif., Nov. 11, 2009 – Doctors with the Kinohi Institute and the University of Innsbruck in Austria devised an imaging technique to detect bacteria in frozen Antarctic lakes, with the ultimate goal of using the technology to identify microbial life in the extreme...
Bruker Names New Officers
Nov 9, 2009 — Bruker Corp., a provider of scientific instruments and solutions based in Billerica, Mass., announced that its board appointed Bill Knight as chief operating officer and Brian Monahan as chief financial officer (CFO), effective Feb. 1, 2010. Knight...
Senate Confirms 14th NIST Director
Nov 9, 2009 — The US Senate recently confirmed Dr. Patrick D. Gallagher as the 14th director of the Commerce Department’s National Institute of Standards and Technology (NIST) by unanimous consent. Gallagher has worked at NIST since 1993 as a scientist and...
Show Plans Laser Tribute
SAN FRANCISCO, Nov. 6, 2009 – Special events celebrating the 50th anniversary of the invention of the laser, including a “Cirque du Lasaire” reception, will mark SPIE Photonics West’s first year in San Francisco. The primary photonics technical symposium and exhibition in North...
T-ray Tool Up and Running
AMES, Iowa, Nov. 5, 2009 – A new terahertz ray (T-ray) instrument installed at Iowa State University will allow scientists to take a unique look at material reliability, biofuel combustion, cancer screening, and other science and engineering research fields by reading...
AMD Lasers Forms Alliances
Nov 4, 2009 — Indianapolis-based AMD Lasers announced strategic partnerships with 1-800-Dentist, Fortune Management and Cetylite Industries, in a move aimed at providing more value for dental professionals that purchase the Picasso diode dental laser, said AMD....

Scope-Headed Rats Roam Free
TÜBINGEN, Germany, Nov. 4, 2009 – By building a tiny laser microscope small enough to mount on a rat’s head, researchers found a way to solve the puzzle of recording meaningful signals from brain cells that calculate perception and attention while the subject is in motion.
Veridiam Names New CFO
Nov 4, 2009 — Veridiam of El Cajon, Calif., announced that Robert Mazzacavallo has been named its chief financial officer. Veridiam is a contract manufacturer of high-precision fabricated assemblies and metal components, serving primarily Fortune 500 companies in...

T Cell Trigger: Sheer Force
BOSTON, Nov. 3, 2009 – An array of techniques including optical tweezers were used to find the "switch" that can swiftly change a T cell – a white blood cell that patrols the bloodstream and organs for signs of disease – from jury to executioner. Revealing this "missing...
Getting VC Funding: Improving Your Odds
Nov 1, 2009 — There is no shortage of good advice on how to get venture capitalists (VCs) to invest in your start-up company. Out of curiosity, I Googled “get VC funding” and found almost 2 million links. One top site is an informative short video by Paul...
