(Phys.org)—The ubiquitous clouds of gas and dust found between stars provide the natal material for new stars and planets. These clouds are also dynamic factories that produce many complex molecules thanks to their rich environment of stellar radiation, dense gas, and dust grains. The grains (most of which are silicates, analogous to sand) act as miniature chemical laboratories. Atoms and molecules from the gas condense onto their surfaces and then interact with one another to form even more complex species. Water, a particularly abundant species, tends to form a layer of ice on the grain surfaces. http://phys.org/news276763040.html Space & Earth Mon, 07 Jan 2013 06:37:33 EST news276763040 A team of researchers at the Freie Universität Berlin, co-ordinated by José Ignacio Pascual, have developed a method that enables efficiently using the random movement of a molecule in order to make a macroscopic-scale lever oscillate. The research was published in Science. http://phys.org/news272819274.html Nanotechnology Thu, 22 Nov 2012 15:08:28 EST news272819274 (PhysOrg.com) -- The new and highly sensitive Cosmic Origins Spectrograph aboard the Hubble Space Telescope has discovered a strong ultraviolet-wavelength absorber on Pluto's surface, providing new evidence that points to the possibility of complex hydrocarbon and/or nitrile molecules lying on the surface, according to a paper recently published in the Astronomical Journal by researchers from Southwest Research Institute and Nebraska Wesleyan University. http://phys.org/news243603572.html Space & Earth Tue, 20 Dec 2011 11:40:03 EST news243603572 Findings by Japanese researchers at the RIKEN Advanced Science Institute and their colleagues at Tohoku University and in the Netherlands have resolved a long-standing debate over the structure of water molecules at the water surface. Published in the Journal of the American Chemical Society, the research combines theoretical and experimental techniques to pinpoint, for the first time, the origin of water's unique surface properties in the interaction of water pairs at the air-water interface. http://phys.org/news236854303.html Chemistry Mon, 03 Oct 2011 09:51:56 EST news236854303 A recently discovered form of the protein that triggers blood clotting may play a key role in the molecular mechanisms leading to the growth of certain metastatic cancers, according to new research reported by an international team of scientists. http://phys.org/news175791619.html Medicine & Health Mon, 26 Oct 2009 16:01:41 EST news175791619 To stretch a supply of salt generally means using it sparingly. http://phys.org/news165054350.html Nanotechnology Wed, 24 Jun 2009 09:26:36 EST news165054350
