High-speed CMOS sensors provide better images Posted: 13 Jan 2012 07:20 AM PST Conventional CMOS image sensors are not suitable for low-light applications such as fluorescence, since large pixels arranged in a matrix do not support high readout speeds. A new optoelectronic component speeds up this process.

Superconducting current limiter guarantees electricity supply of the Boxberg power plant Posted: 13 Jan 2012 07:20 AM PST For the first time, a superconducting current limiter based on YBCO strip conductors has now been installed at a power plant. At the Boxberg power plant of Vattenfall, the current limiter protects the grid for own consumption that is designed for 12,000 volts and 800 amperes against damage due to short circuits and voltage peaks.

NIH study shows 32 million Americans have autoantibodies that target their own tissues Posted: 13 Jan 2012 06:38 AM PST More than 32 million people in the United States have autoantibodies, which are proteins made by the immune system that target the body's tissues and define a condition known as autoimmunity, a study shows. The first nationally representative sample looking at the prevalence of the most common type of autoantibody, known as antinuclear antibodies (ANA), found that the frequency of ANA is highest among women, older individuals, and African-Americans.

Software for analyzing digital pathology images proving its usefulness Posted: 13 Jan 2012 06:38 AM PST As tissue slides are more routinely digitized to aid interpretation, a software program is proving its utility. In bladder cancer test case, a new software tool separates malignancy from background tissue.

Dark chocolate and red wine are heart-healthy foods of love, dietitians say Posted: 13 Jan 2012 06:38 AM PST Dietitian says resveratrol which lowers blood sugar is found in red wine and also dark chocolate, making them ideal for heart holidays like Valentine's Day and year round consumption for heart health.

Particle-free silver ink prints small, high-performance electronics Posted: 13 Jan 2012 06:36 AM PST Materials scientists have developed a new reactive silver ink for printing high-performance electronics on ubiquitous, low-cost materials such as flexible plastic, paper or fabric substrates. The reactive ink has several advantages over particle-based inks: low processing temperature, high conductivity, and the ability to print very small features.

Horse fly named in honor of Beyonce Posted: 13 Jan 2012 06:36 AM PST A previously unnamed species of horse fly whose appearance is dominated by its glamorous golden lower abdomen has been named in honor of American pop diva, Beyonce -- a member of the former group Destiny's Child, that recorded the 2001 hit single, "Bootylicious."

Criegee intermediates found to have big impact on troposphere Posted: 13 Jan 2012 06:36 AM PST Scientists report direct measurements of reactions of a gas-phase Criegee intermediate using photoionization mass spectrometry. They found that oxidation of SO2 by Criegee intermediate is much faster than modelers assumed, so Criegee reactions may be a major tropospheric sulfate source, changing predictions of tropospheric aerosol formation.
