Cause of Cataracts Pinpointed with AFM Imaging

At the Institut Curie, Simon Scheuring, beneficiary of the Inserm Avenir program and coordinator of the CNRS/Inserm "Atomic force microscopy (AFM) of proteins in native membranes" team, has for the first time observed a diseased tissue at very high resolution using atomic force microscopy (AFM).

Nanoscale Titanium Dioxide Particles Help Protect Plastics from Sun Damage

DuPont today introduced DuPont(TM) Light Stabilizer 210, a product designed as sun protection for plastics. The product uses extremely small particles of titanium dioxide to efficiently absorb ultraviolet light, protecting plastic and anything it covers from the sun's damaging rays. Because a sizeable percentage of titanium dioxide particles in the product are nanoscale, it was selected as a demonstration case for application of the Nano Risk Framework that DuPont and Environmental Defense introduced in June. The Framework is a systematic and disciplined process to evaluate and address the potential risks of nanoscale materials.

FLASH Facility Achieved World Record By Generating Flashes of Laser Light

After a successful upgrade, the FLASH facility achieved a world premiere by generating flashes of laser light at the minuscule wavelength of 6.5 nanometres (nm), thereby breaking the world record of 13.5 nm it established one year ago. The facility now provides even better research opportunities for the second measuring period, which will begin on November 19, 2007.

Laser Efficiency Increased Using Ceramic in Optical Pumping Cavities

Lasers have been used in medicine for many years, mostly as minimally invasive surgical cutting tools. However, in recent years there have been many advances in the market, and the range of applications for lasers and light-based systems continues to expand across several specialities, especially in ophthalmology and cosmetic treatments. This has created a demand for increased efficiency of lasers and high intensity pulsed lamps, while creating new systems that are more compact, gentler, quicker and more cost-effective.

Micron-Scale Metallic Marking Grid Could Improve Understanding, Diagnosis of Alzheimer's and Other Diseases

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a method for correlating the results of microscopic imaging techniques in a way that could lead to improved understanding, diagnosis, and possibly treatment of a variety of disease conditions, including Alzheimer's disease. The Laboratory has filed a U.S. provisional patent application for the invention.
