New Imaging Technology that Produces the Best 3-D Resolution Ever Seen with an Optical Microscope

The shapes of some of the tiniest cellular structures are coming into sharper focus at the Howard Hughes Medical Institute's Janelia Farm Research Campus, where scientists have developed a new imaging technology that produces the best three-dimensional resolution ever seen with an optical microscope.

Organic Electronic Devices Possible with Supercritical Carbon Dioxide Process

Someday, moving a large, flat-screen TV across the country might be as simple as taking it off the wall, rolling it up and sliding it into a study tube. That's the vision of researchers Christopher Ober and George Malliaras at Cornell University, and Andrew Holmes at the University of Melbourne, Australia, who are fabricating organic semiconducting materials with a little help from supercritical carbon dioxide, or CO2.

Pore-free Ceramics Shine New Light on Lasers

To most people, the word "ceramics," refers to opaque clay flower pots or translucent porcelain tea cups. But not all ceramics block or scatter light. Gary L. Messing, distinguished professor of ceramic science and engineering, and his group at Pennsylvania State University, are developing a brand new class of ceramics that are so pure and perfectly transparent, they can be used as a substitute for crystals in solid-state lasers.

Anisotropy Imaging Technique Now Available for LSM 710 Laser Scanning Microscope from Carl Zeiss

The anisotropy imaging technique is now available for the serial equipment of the LSM 710 laser scanning microscope from Carl Zeiss. It supplements the special imaging techniques such as RICS (Raster Image Correlation Spectroscopy) and FCS (Fluorescence Correlation Spectroscopy) already possible with the LSM 710.

UV Light-Enhanced Tooth Bleaching Not Only a Con, but Dangerous to Your Eyes and Skin

UV light-enhanced tooth bleaching is not only a con, but is dangerous to your eyes and skin, says a Royal Society of Chemistry journal.

Blue Light Destroys Antibiotic-Resistant Staph Infection

Two common strains of methicillin-resistant Staphylococcus aureus, commonly known as MRSA, were virtually eradicated in the laboratory by exposing them to a wavelength of blue light, in a process called photo-irradiation that is described in a paper published online ahead of print in Photomedicine and Laser Surgery.

New Way of Making LEDs Could See Household Lighting Bills Reduced by up to 75 Percent

A new way of making LEDs could see household lighting bills reduced by up to 75% within five years. Gallium Nitride (GaN), a man-made semiconductor used to make LEDs (light emitting diodes), emits brilliant light but uses very little electricity. Until now high production costs have made GaN lighting too expensive for wide spread use in homes and offices.

Surgeons at Northwestern Memorial Hospital Among First in the Country to Use New Micro-Laser

Surgeons at Northwestern Memorial Hospital are among the first in the country to use a new micro-laser, which uses light energy in place of a cutting tool to remove complicated brain and spine tumors. The technique offers greater precision and efficiency during surgery, reducing the incision size, surgery time and patient recovery period following surgery.
