With the appearance of gracefully swooping beams of light or a colorful array of feathers, a dazzling photo of Pleurosigma (marine diatoms) has won the 2008 Nikon Small World Photomicrography Competition. Michael Stringer of Westcliff-on-Sea, Essex, United Kingdom took home the top honor with this image, which was magnified 200 times and taken using darkfield and polarized light.
Charles Rosenblatt, professor of physics and macromolecular science at Case Western Reserve University, and his research group have developed a method of 3D optical imaging of anisotropic fluids such liquid crystals, with volumetric resolution one thousand times smaller than existing techniques. A research paper detailing the team's findings appeared in the September 21 advanced online publication of Nature Physics. The print version will be available soon.
A new research field called transformation optics may usher in a host of radical advances including a cloak of invisibility and ultra-powerful microscopes and computers by harnessing nanotechnology and "metamaterials."
With the Primo Star iLED, Carl Zeiss is introducing a new fluorescence microscope which enables the fast and reliable detection of tuberculosis. Together with FIND, the Foundation for Innovative New Diagnostics, which co-developed the microscope, the optics company will be presenting the system at the 39th World Union Conference on Lung Health in Paris from 17 to 20 October 2008.
Acclaimed scientists and photographers from around the world will share their scientific research, discoveries and observations of natural wonders in an international photography exhibition opening next month at Rochester Institute of Technology.
Researchers in Japan have developed a design concept for a device that allows imaging at scales previously impossible for optical instruments. Their advance is based on novel imaging techniques that allow optical imaging in the subwavelength regime, where the wavelength used is larger than the smallest features of the object being imaged.
Contrary to textbook wisdom, the unusually long illuminating wavelength of 118 µm did not at all preclude researchers from the Max-Planck-Institute of Biochemistry (MPIB) to resolve details as small as 40 nm (= 0.04 µm). This was made possible by the use of extreme THz field concentration at the sharp tip of a scanning atomic force microscope (AFM).
Researchers at NorthShore University HealthSystem (NorthShore) and Northwestern University have discovered that fiber optic technology can for the very first time effectively measure blood levels in the colonic lining (mucosa) in humans, thus having potential applications for analyzing risk of colon cancer. The study appears in the October 2008 issue of Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute.
Lucid, Inc. today announced that it has received U.S. Food and Drug Administration (FDA) 510(k) clearance to market its VivaScope® System. VivaScope confocal imagers provide noninvasive, in vivo cellular resolution images of skin and are now specifically cleared "...for review by physicians to assist in forming a clinical judgment."
For the second consecutive year, Nikon Instruments is opening up its Small World Photomicrography Competition for the public to choose its favorite image for recognition as the Popular Vote winner. Visitors to www.nikonsmallworld.com have until 5:00 pm EDT on Friday, October 10th to vote for their favorite "winning image" from among the top 115 finalists chosen by this year's panel of judges from over 2,000 entries.
