Microscopy News
Modified GFP enables in vivo imaging of cellular signaling in the heart
May 1, 2006 — The efficient functioning of the heart — an organ that begins to operate before it is fully developed — depends on the coordinated release and reuptake of calcium ions from organelles within cells. Subtle dysfunctions of this process can...
Multicolor analysis extends potential of DNA microarrays
May 1, 2006 — Microarray platforms are used everywhere — from academic research centers to public health laboratories to pharmaceutical companies. By enabling analysis of thousands of DNA sequences at a time, they have dramatically increased throughput and...
Olympus America Inc.
May 1, 2006 — Olympus America Inc. of Melville, N.Y., has combined its Scientific Equipment and Diagnostic Systems Groups and Life Science Business Development unit to create the Life Science Group. The move is designed to align the company’s organization...
Optical filters
May 1, 2006 — The updated Web site of Omega Optical Inc. features new graphics, including images of products and manufacturing, and galleries of images provided by life sciences collaborators. Among the improvements, customers can now search for products by...
Optical systems
May 1, 2006 — Optical Insights, a designer, developer and manufacturer of optical systems for a variety of spectral and polarization imaging applications, has launched a Web site geared toward researchers and OEMs. The portal details the company’s products...
Real-time imaging during centrifugation
May 1, 2006 — People who lose blood or whose bodies aren’t producing enough can receive transfusions. However, they sometimes need only certain blood components, such as red blood cells, plasma and platelets. In these cases, centrifugation is used to...
Researchers probe esophageal cancer with nine optical modalities
May 1, 2006 — For esophageal cancer, as with most cancers, early diagnosis and treatment is the most effective way to handle the disease. For this type of cancer, physicians look for lesions that could be malignant by using an endoscope to examine the lining of...
Restoring vision with light-sensitive protein
May 1, 2006 — A loss of photoreceptor cells caused by retinal degenerative diseases often results in complete blindness. Zhuo-Hua Pan of Wayne State University School of Medicine in Detroit and colleagues explored the possibility of converting nonphotosensitive...
Unexpected step in malaria invasion
May 1, 2006 — Most malaria vaccines work only between 20 and 50 percent of the time. Thus, scientists are eager to understand more about how the malaria parasites infect their host. New imaging data has revealed a previously unrecognized step on the...
Genovese Named VP at JEOL
Apr 13, 2006 — Peter Genovese was named vice president of JEOL USA, a Peabody, Mass., supplier of electron microscopes and analytical instruments. Genovese has held successive management positions since joining JEOL in 1983, most recently as sales manager for...
A Spotlight on Biophotonics in Canada
Apr 1, 2006 — Canada has demonstrated its commitment to building a sustainable future for biophotonics through education, research and industrial development. Numerous initiatives exist, at federal and provincial levels, whose mandate is to establish a firm...
Biosensing with microlenses
Apr 1, 2006 — To see something small, you need a magnifier — and that is what a group of researchers at the Georgia Institute of Technology in Atlanta turned to in developing a label-free biosensor. For their work, they used hydrogel microlenses to monitor...
Carl Zeiss MicroImaging GmbH
Apr 1, 2006 — The Microscopy Group of Carl Zeiss has been incorporated into Carl Zeiss MicroImaging GmbH. The company will expand its global activities in the fields of microscopy solutions, systems for research, spectral sensors, and laboratory applications....
Liquid crystals report cell differentiation
Apr 1, 2006 — Liquid crystals — the substance used in electronic displays — also can be used to monitor stem cell differentiation. Researchers at the University of Wisconsin-Madison have devised a liquid crystal-based cell culture system that may aid...
Mosquitoes’ hearing properties profiled
Apr 1, 2006 — Researchers from the University of Bristol in the UK have discovered that mosquitoes can respond to sound by appropriately amplifying or reducing incoming noise for optimal hearing, and they are keen to understand how the insects mechanically...
New method offers alternative to optical trapping
Apr 1, 2006 — Researchers use optical trapping to answer a variety of biological questions. However, the technique requires optical systems with high numerical apertures and short working distances and is applicable only in shallow samples of fluid with low...
Nikon Small World renews call for entries
Apr 1, 2006 — Nikon Instruments Inc. of Melville, N.Y., has renewed its call for entries for the 32nd annual Nikon Small World Competition, founded to recognize those involved with photomicrography. Participants may submit up to three images, either on 35-mm...
Second-harmonic imaging with minimal damage
Apr 1, 2006 — When researchers at Cornell University in Ithaca, N.Y., and the University of Florence in Italy set out to optimize second-harmonic-generation microscopy, they did so to improve measurements of neuronal membrane potentials. For this to work, though,...
Virtual Microscopy Slides into Place
Apr 1, 2006 — Palos Pathology Associates Ltd. provides pathology services to a 300-bed community hospital in suburban Chicago, and Dr. Stephen G. Ruby, president of the company, is thinking of expanding the geographic area that it covers. In the past, that would...
We got the (tiny) beat
Apr 1, 2006 — Researchers at the University of Illinois at Urbana-Champaign and at Howard Hughes Medical Institute, both in Urbana, have the beat — at least on the nanometer scale. They have constructed a DNA-based nanomechanical device that displays an...
