New insight into gaseous and dust discs around stars (October 30, 2010) -- Researchers offer new insight into the structure of the gaseous and dust disc around a so-called 'Herbig Be' star. Herbig Be stars are surrounded by a disk with gaseous and solid particles. ... > full story
New software eases analysis of insect in motion (October 30, 2010) -- Researchers are using two high-speed cameras and a computer program they developed to quickly and accurately analyze the simultaneous movement of all 26 leg joints in a walking cockroach. They have made the program free and open-source for other insect researchers to use. ... > full story
Shuttle mice to boost disease research: Experiment on last flight of Discovery will probe spaceflight-induced immune-system impairment (October 30, 2010) -- When the space shuttle Discovery lifts off on its final flight Nov. 2, its six astronauts will be joined by 16 mice -- part of a long-term NASA effort aimed at understanding why spaceflight makes humans more vulnerable to infection by viruses and bacteria. ... > full story
Study links fresh Mars gullies to carbon dioxide (October 30, 2010) -- A growing bounty of images from NASA's Mars Reconnaissance Orbiter reveals that the timing of new activity in one type of the enigmatic gullies on Mars implicates carbon-dioxide frost, rather than water, as the agent causing fresh flows of sand. ... > full story
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
