Newly merged black hole eagerly shreds stars (April 9, 2011) -- A galaxy's core is a busy place, crowded with stars swarming around an enormous black hole. When galaxies collide, it gets even messier as the two black holes spiral toward each other, merging to make an even bigger gravitational monster. Once it is created, the monster goes on a rampage. The merger kicks the black hole into surrounding stars. There it finds a hearty meal, shredding and swallowing stars at a rapid clip. ... > full story
Test moves U.S. Navy a step closer to lasers for ship self-defense (April 9, 2011) -- U.S. Navy researchers have successfully tested a solid-state, high-energy laser from a surface ship, which disabled a small target vessel. ... > full story
NASA's next Mars rover nears completion (April 8, 2011) -- Assembly and testing of NASA's Mars Science Laboratory spacecraft is far enough along that the mission's rover, Curiosity, looks very much as it will when it is investigating Mars. ... > full story
NASA telescope ferrets out planet-hunting targets (April 8, 2011) -- Astronomers have come up with a new way of identifying close, faint stars with NASA's Galaxy Evolution Explorer satellite. The technique should help in the hunt for planets that lie beyond our solar system, because nearby, hard-to-see stars could very well be home to the easiest-to-see alien planets. ... > full story
Nature helps to solve a sticky problem: Beetle foot pads may inspire novel artificial adhesives (April 8, 2011) -- The arrays of fine adhesive hairs or 'setae' on the foot pads of many insects, lizards and spiders give them the ability to climb almost any natural surface. Researchers have found that the different forces required to peel away these adhesive hairs from surfaces are what allows beetles to adhere to diverse surfaces, thereby reducing the risk of detachment. Their study provides the first adhesive force measurements from single microscopic setae in a live animal. ... > full story
Quantum mapmakers complete first voyage through spin liquid (April 8, 2011) -- Scientists have mapped a state of matter called 'quantum spin liquid', whose existence was proposed in the 1970s but which has only been observed recently. ... > full story
Nanoparticles increase biofuel performance, lower emissions (April 8, 2011) -- A new study shows that the addition of alumina nanoparticles can improve the performance and combustion of biodiesel, while producing fewer emissions. ... > full story
Personal touch: Hearing a heartbeat has the same effect as looking each other in the eye (April 8, 2011) -- Hearing the heartbeat of someone you are talking to gives the same feeling of personal contact as looking each other in the eye. ... > full story
Simple chemical cocktail shows first promise for limb re-growth in mammals (April 8, 2011) -- Move over, newts and salamanders. The mouse may join you as the only animal that can re-grow their own severed limbs. Researchers are reporting that a simple chemical cocktail can coax mouse muscle fibers to become the kinds of cells found in the first stages of a regenerating limb. Their study is the first demonstration that mammal muscle can be turned into the biological raw material for a new limb. ... > full story
Mussel adhesive inspires tough coating for living cells (April 8, 2011) -- Inspired by Mother Nature, scientists are reporting development of a protective coating with the potential to enable living cells to survive in a dormant condition for long periods despite intense heat, dryness and other hostile conditions. They liken the coating to the armor that encloses the spores that protect anthrax and certain other bacterial cells, making those microbes difficult to kill. ... > full story
Chemical engineers have designed molecular probe to study disease (April 8, 2011) -- Chemical engineers expect that their new process to create molecular probes may eventually result in the development of new drugs to treat cancer and other illnesses. ... > full story
Video games effective treatment for stroke patients (April 8, 2011) -- Virtual reality and other video games can significantly improve motor function in stroke patients, according to new research. ... > full story
