A fleet of kites could harvest enough energy from high-altitude winds to power New York City, with an average wind power density of up to 16 kilowatts per square meter, report researchers from the Carnegie Institution and California State University. Technologies proposed to harvest these high altitude winds include tethered, kite-like turbines that would be floated to the altitude of the jet streams at an altitude of 20,000-50,000 feet and transm...

Nanoparticles that can attack plaque -- a major cause of cardiovascular disease -- have been developed by UC Santa Barbara researchers.The nanoparticles are lipid-based collections of molecules that form a sphere called a micelle that has a peptide (a piece of protein) on its surface. The peptide binds to the surface of the plaque, rupturing it. (Source: http://www.sciencedaily.com/releases/2009/06/090604155619.htm)

PIKAMAB believes that it can make monoclonal antibodies (engineered to hone in on specific biological targets) more effective by grouping patients together based on their genotype and offering a customized antibody developed for that genotype. The company hopes that this "stratified" approach to drug development and treatment will help drug companies achieve better results. (Source: http://www.technologyreview.com/biomedicine/22795/)

Custom animation in PowerPoint lectures negatively impacts student learning, University of North Carolina researchers have found. Animated slides meant to present information incrementally actually require greater concentration, which makes it harder to remember content as well as reducing overall exposure time to the "complete" slide, the researchers found.
