Making Discrete Carbon Nanoparticles - SpaceDaily  Carnegie Mellon University scientists have developed an attractive way to make discrete carbon nanoparticles for electrical components used in industry and research. "Our well-defined carbon nanoparticles should find a wide range of applications, especially in energy storage/conversion devices and in display technologies." The Carnegie Mellon group is currently working on using carbon nanoparticles as active materials in field emitter arrays for flat panel screen displays. This technology to produce carbon nanostructures also could be adapted to produce solar panels that convert sunlight into electrical energy. 
A Picture Is Worth A Thousand Miles - SpaceDaily  The body size of ancient creatures, bivalves and brachiopods, could tell geoscientists a lot about the creatures' life history and about the ecology of the times in which they lived. However, traveling the world to measure these creatures' fossils would take several life-times and more travel funds than scientists usually have. Changes in body size could reveal whether an organism evolved and became more efficient or whether environmental changes had an impact. "But no one has compiled a list of how body size changed for a group of animals over long time periods," Krause says.

Protein Folding On A Chip - SpaceDaily  Scientists at the U.S. Department of Energy's Brookhaven National Laboratory are proposing to use a supercomputer originally developed to simulate elementary particles in high-energy physics to help determine the structures and functions of proteins, including, for example, the 30,000 or so proteins encoded by the human genome. Unlike typical parallel processors, the 10,000 processors in this supercomputer (called Quantum Chromodynamics on a Chip, or QCDOC, for its original application in physics) each contain their own memory and the equivalent of a 24-lane superhighway for communicating with one another in six dimensions.
