The new "solar steam" method is so effective it can even produce steam from icy cold water. The technology's inventors said they expect it will first be used in sanitation and water-purification applications in the developing world.Mon, 19 Nov 2012 14:06:06 ESThttp://www.sciencedaily.com/releases/2012/11/121119140627.htmAstrophysicists identify a 'super-Jupiter' around massive starhttp://www.sciencedaily.com/releases/2012/11/121119140621.htm Astrophysicists have discovered a 'super-Jupiter' around the massive star Kappa Andromedae. It represents the first new imaged exoplanet system in almost four years, has a mass about 13 times that of Jupiter and an orbit somewhat larger than Neptune's. The star around which the planet orbits has a mass 2.5 times that of the Sun, making it the highest mass star to ever host a directly observed planet.Mon, 19 Nov 2012 14:06:06 ESThttp://www.sciencedaily.com/releases/2012/11/121119140621.htmGreenland's viking settlers gorged on sealshttp://www.sciencedaily.com/releases/2012/11/121119132311.htm Greenland's viking settlers, the Norse, disappeared suddenly and mysteriously from Greenland about 500 years ago. Natural disasters, climate change and the inability to adapt have all been proposed as theories to explain their disappearance. But now a Danish-Canadian research team has demonstrated the Norse society did not die out due to an inability to adapt to the Greenlandic diet: an isotopic analysis of their bones shows they ate plenty of seals.Mon, 19 Nov 2012 13:23:23 ESThttp://www.sciencedaily.com/releases/2012/11/121119132311.htmNeed to filter water?

Researchers found that a shortage of the genetic factor KLF4, which regulates endothelial cells lining the interior of blood vessels, makes the lining more prone to the buildup of plaque and fat deposits. Further, the deficiency made the blood vessel more susceptible to clot formation.Mon, 19 Nov 2012 11:43:43 ESThttp://www.sciencedaily.com/releases/2012/11/121119114300.htm3-D light switch for the brain: Device may help treat Parkinson's, epilepsy; aid understanding of consciousnesshttp://www.sciencedaily.com/releases/2012/11/121119114249.htm A new tool for neuroscientists delivers a thousand pinpricks of light to individual neurons in the brain.

Unlike most other cloaking techniques that rely on transformation optics, this one is based on the influence of the ocean floor?s topography on the various ?layers? of ocean water. At the American Physical Society?s (APS) Division of Fluid Dynamics (DFD) meeting, being held November 18-20, 2012, in San Diego, Calif., Reza Alam, assistant professor of mechanical engineering at the University of California, Berkeley, will describe how the variation of density in ocean water can be used to cloak floating objects against incident surface waves.Mon, 19 Nov 2012 10:45:45 ESThttp://www.sciencedaily.com/releases/2012/11/121119104529.htmSound bullets in waterhttp://www.sciencedaily.com/releases/2012/11/121119104527.htm Sound waves are commonly used in applications ranging from ultrasound imaging to hyperthermia therapy, in which high temperatures are induced, for example, in tumors to destroy them. In 2010, researchers developed a nonlinear acoustic lens that can focus high-amplitude pressure pulses into compact ?sound bullets.? In that initial work, the scientists demonstrated how sound bullets form in solids. Now, they have done themselves one better, creating a device that can form and control those bullets in water.Mon, 19 Nov 2012 10:45:45 ESThttp://www.sciencedaily.com/releases/2012/11/121119104527.htmOwls' ability to fly in acoustic stealth provides clues to mitigating conventional aircraft noisehttp://www.sciencedaily.com/releases/2012/11/121119104525.htm Owls have the uncanny ability to fly silently, relying on specialized plumage to reduce noise so they can hunt in acoustic stealth.
