Three-dimensional maps of brain wiring (October 29, 2010) -- Scientists have developed a software tool that physicians can use to easily study the wiring of the brains of their patients. The tool converts MRI scans using special techniques to three-dimensional images. This now makes it possible to view a total picture of the winding roads and their contacts without having to operate. ... > full story

Researchers use math, maps to plot malaria elimination plan (October 29, 2010) -- An international team of researchers has used mathematical models and maps to estimate the feasibility of eliminating malaria from countries that have the deadliest form of the disease. ... > full story

Space radar provides a taste of Comet Hartley 2 (October 29, 2010) -- Exactly one week before the world gets a new look at comet Hartley 2 via NASA's EPOXI mission, observations of the comet by the Arecibo Planetary Radar in Puerto Rico have offered scientists a tantalizing preview. ... > full story

‘Wireless’ humans could form backbone of new mobile networks (October 29, 2010) -- Members of the public could form the backbone of powerful new mobile internet networks by carrying wearable sensors. The novel sensors could create new ultra high bandwidth mobile internet infrastructures and reduce the density of mobile phone base stations, according to researchers. ... > full story

Organic solvent system may improve catalyst recycling and create new nanomedicine uses (October 29, 2010) -- Noble metals such as platinum and palladium are becoming increasingly important because of growth in environmentally friendly applications such as fuel cells. A new solvent system could improve the recycling of these metals. ... > full story

New system for monitoring electricity use heralds greener homes and cheaper bills (October 29, 2010) -- During the winter months the days grow colder and the nights longer causing households to use more electricity, often resulting in higher bills. Most households have no way of monitoring how much electricity is being consumed; however, researchers believe a new monitoring system may soon be available for residential use. ... > full story

Earth-sized planets may be common throughout our galaxy, NASA survey suggests (October 29, 2010) -- Nearly one in four stars similar to the sun may host planets as small as Earth, according to a new study. The study is the most extensive and sensitive planetary census of its kind. Astronomers used the W.M. Keck Observatory in Hawaii for five years to search 166 sun-like stars near our solar system for planets of various sizes, ranging from three to 1,000 times the mass of Earth. All of the planets in the study orbit close to their stars. The results show more small planets than large ones, indicating small planets are more prevalent in our Milky Way galaxy. ... > full story

Better detection for diagnostics and biochemical defense (October 29, 2010) -- Current detection methods for chemical and biological molecules involve using tiny, molecular "labels," typically fluorescent or radioactive entities, which can be a time-consuming and expensive process. A research team recently developed a system for detecting chemical and biological molecules without labels, and they expect the technology to have broad applications ranging from clinical diagnostics to drug development, as well as homeland security and environmental monitoring for biological and chemical weapons. ... > full story

Brain's journey from early Internet to modern-day fiber optics: Computer program shows how brain's complex fiber tracks mature (October 29, 2010) -- The brain's inner network becomes increasingly more efficient as humans mature. Now, for the first time without invasive measures, a new study has verified these gains with a powerful new computer program. ... > full story

New strategy to kill bugs -- even those in hiding (October 29, 2010) -- New strategies to apply antibiotics more effectively to hibernating bugs have been developed by researchers in the UK. ... > full story

Making better biosensors with electron density waves (October 29, 2010) -- An emerging field with the tongue-twisting name of "optofluidic plasmonics" promises a new way to detect and analyze biological molecules for drug discovery, medical diagnostics, and the detection of biochemical weapons. Researchers have succeeded in merging a microfluidics system with plasmonics -- sometimes called "light on a wire" -- onto a single platform. Plasmonics is based on electron waves on a metal surface excited by incoming light waves. ... > full story

Emotion processing in brain is influenced by color of ambient light, study suggests (October 29, 2010) -- Researchers in Europe investigated the immediate effect of light, and of its color composition, on emotion brain processing using functional magnetic resonance imaging. The results of their study show that the color of light influences the way the brain processes emotional stimuli. ... > full story
