New approach to overcome key hurdle for next-generation superconductors

ScienceDaily (Oct. 27, 2011) — Researchers from North Carolina State University have developed a new computational approach to improve the utility of superconductive materials for specific design applications -- and have used the approach to solve a key research obstacle for the next-generation superconductor material yttrium barium copper oxide (YBCO).A superconductor is a material that can carry electricity without any loss -- none of the energy is dissipated as heat, for example. Superconductive...

To diagnose heart disease, visualization experts recommend a simpler approach

ScienceDaily (Oct. 27, 2011) — A team of computer scientists, physicists, and physicians at Harvard has developed a simple yet powerful method of visualizing human arteries that may result in more accurate diagnoses of atherosclerosis and heart disease.The prototype tool, called "HemoVis," creates a 2D diagram of arteries that performs better than the traditional 3D, rainbow-colored model. In a clinical setting, the tool has been shown to increase diagnostic accuracy from 39% to 91%.Presented Oct....
