Using ESO's successful HARPS spectrograph, a team of astronomers has found that Sun-like stars that host planets have destroyed their lithium much more efficiently than "planet-free" stars. This finding does not only shed light on the lack of lithium in our star, but also provides astronomers with a very efficient way of finding stars with planetary systems. http://www.physorg.com/news177168122.html Space & Earth Wed, 11 Nov 2009 13:22:39 EST news177168122 Buildings typically provide shelter from the elements, but one Ryerson University researcher thinks structures ought to relate more to the environment instead. To this end, she has created architectural "skins," which interact with the weather to ultimately create environmental structures that integrate form with function. http://www.physorg.com/news176732821.html Other Sciences Fri, 06 Nov 2009 12:27:46 EST news176732821 Those oft-maligned, and highly embellished, graphs and charts in USA Today and other media outlets may actually help people understand data more effectively than traditional graphs, according to new research from North Carolina State University. http://www.physorg.com/news176550708.html Other Sciences Wed, 04 Nov 2009 09:59:18 EST news176550708 (PhysOrg.com) -- The Orion Nebula is one of the most beautiful sights of the winter night sky, its gas and dust glowing from the intense ultraviolet radiation of a cluster of massive young stars. http://www.physorg.com/news175507575.html Space & Earth Fri, 23 Oct 2009 09:07:12 EST news175507575 (PhysOrg.com) -- A chemist at NASA's Jet Propulsion Laboratory in Pasadena, Calif., has developed a technology intended to rapidly assess any presence of microbial life on spacecraft.

Scientists at Arizona State University are studying how the distribution of these elements on Earth - or beyond - shapes the distribution of life, the state of the environment and the course of evolution. http://www.physorg.com/news147955390.html Space & Earth Mon, 08 Dec 2008 10:43:10 EST news147955390 Much of human DNA is the genetic equivalent of e-mail spam: short repeated sequences that have no obvious function other than making more of themselves. http://www.physorg.com/news143908620.html Biology Wed, 22 Oct 2008 15:37:00 EST news143908620 Our genome contains many genes encoding proteins that are similar to those of other organisms, suggesting evolutionary relationships; however, protein-coding genes account for only a small fraction the genome, and there are many other DNA sequences that are conserved across species. What are these sequences doing, and do we really need them at all? In a study published online today in Genome Research, researchers have delved into this mystery and found that evolution has actively kept them in our genome. http://www.physorg.com/news142100209.html Medicine & Health Wed, 01 Oct 2008 17:16:49 EST news142100209 New research in the latest issue of the Society of Chemical Industry's (SCI) Journal of the Science of Food and Agriculture shows there is no evidence to support the argument that organic food is better than food grown with the use of pesticides and chemicals http://www.physorg.com/news137324269.html Chemistry Thu, 07 Aug 2008 10:37:49 EST news137324269
