Detailed, accurate evolutionary trees that reveal the relatedness of living things can now be determined much faster and for thousands of species with a computing method developed by computer scientists and a biologist at The University of Texas at Austin…
Since the discovery of carbon nanotubes in the early 1990s, nanotubes and nanowires have been the focus of scientific and technological interest. It has since also proved possible to produce these tiny structures from materials other than carbon. Possible applications range across many areas, including microelectronic circuits, sensor technology, and special fibre optics and light-emitting nanotubes for displays. A team of researchers led by Wolfgang Tremel at Johannes Gutenberg University Mainz have now developed a new technique for producing tin disulphide nanotubes. According to the report published in the journal Angewandte Chemie, the scientists have found a way of 'growing' SnS2 tubules from a metal droplet…
NASA successfully launched the Lunar Crater Observation and Sensing Satellite, or LCROSS, Thursday on a mission to search for water ice in a permanently shadowed crater at the moon's south pole. The satellite lifted off on an Atlas V rocket from Cape Canaveral Air Force Station, Fla., at 5:32 PM EDT, with a companion mission, the Lunar Reconnaissance Orbiter, or LRO…
