New Algorithm Significantly Boosts Routing Efficiency Of Networks (August 22, 2008) -- A time-and-money-saving question shared by commuters in their cars and networks sharing ever-changing Internet resources is: "What's the best way to get from here to there?" ... > full story
Computer-generated Images: Hollywood Hair Will Be Captured At Last (August 22, 2008) -- Imagine avatars of your favorite actors wandering through 3-D virtual worlds with hair that looks almost exactly like it does in real life. This level of realism for animated hairstyles is one step closer to the silver screen, thanks to new research being presented at SIGGRAPH, one of the most competitive computer graphics conferences in the world. ... > full story
Improved Technique Determines Structure In Membrane Proteins (August 22, 2008) -- By combining custom-built spectrometers, novel probe designs and faster pulse sequences, scientists have developed unique capabilities for probing protein chemistry and structure through the use of solid-state nuclear magnetic resonance spectroscopy. ... > full story
Stellar Stillbirths: Brown Dwarfs Revealed As Third Class Of Celestial Bodies After Stars And Planets (August 22, 2008) -- Brown dwarfs need to be treated as a separate class of celestial body in addition to stars and planets, researchers have found. Until now, brown dwarfs had been merely regarded as stars which were below normal size. However, they may well be stellar 'miscarriages.' ... > full story
Radioactive Waste Recycling No Longer A Pain In The Ash (August 22, 2008) -- A new recycling plant will soon recover uranium from the ashes of radioactive garbage to be recycled back into nuclear fuel using an efficient, environmentally friendly technology inspired by decaffeinated coffee. The technique's future may even hold the key to recycling the most dangerous forms of radioactive waste. ... > full story
Mystery Of Young Stars Near Black Holes Solved (August 22, 2008) -- The mystery of how young stars can form within the deep gravity of black holes has been solved by astrophysicists. Until now, scientists have puzzled over how stars could form around a black hole, since molecular clouds - the normal birth places of stars - would be ripped apart by the black hole's immense gravitational pull. ... > full story
Coatings To Help Medical Implants Connect With Neurons (August 22, 2008) -- Plastic coatings could someday help neural implants treat conditions as diverse as Parkinson's disease and macular degeneration. The coatings encourage neurons in the body to grow and connect with the electrodes that provide treatment. ... > full story
MRI Technology Developed That Non-invasively Locates, Quantifies Specific Cells In The Body (August 22, 2008) -- MRI isn't just for capturing detailed images of the body's anatomy. Thanks to new imaging reagents and technology, MRI can be used to visualize -- with "exquisite" specificity -- cell populations in the living body. The ability to non-invasively locate and track cells, will greatly aid the study and treatment of cancer, inflammation, and autoimmune diseases, as well as provide a tool for advancing clinical translation of cellular regenerative medicine. ... > full story
Oil, Gas Seismic Work Not Affecting Gulf Sperm Whales, Study Shows (August 22, 2008) -- In recent years, there has been concern that man-made noise may be a cause of stress for dolphins, whales and other marine mammals, but the results of a five-year study show that noise pollution seems to have minimal effect on endangered sperm whales in the Gulf of Mexico, say researchers from Texas A&M University who led the project and released their 323-page report today at the Houston Museum of Natural Science. ... > full story
Space Age Engineers To Verify Control Software For Future Robotic Inter-planetary Missions (August 22, 2008) -- An international team of engineers is to develop mission-critical control software for future European robotic space missions, it has been announced. ... > full story
Optical Computing Closer To Reality (August 22, 2008) -- Scientists have theorized a way to increase the speed of pulses of light that bound across chains of tiny metal particles to past the speed of light by altering the particle shape. Application of this theory would use nanosized metal chains as building blocks for novel optoelectronic and optical devices. ... > full story
True Properties Of Carbon Nanotubes Measured (August 21, 2008) -- Carbon nanotubes' atomic structure should, in theory, give them mechanical and electrical properties far superior to most common materials. Unfortunately, theory and experiments have failed to converge on the true mechanical properties of carbon nanotubes. Researchers recently made the first experimental measurements of the mechanical properties of carbon nanotubes that directly correspond to the theoretical predictions. They used a nanoscale material testing system based on MEMS technology. ... > full story
