(PhysOrg.com) -- Microscopic ridges contouring the surface of flower petals might play a role in flashing that come-hither look pollinating insects can't resist. Michigan State University scientists and colleagues now have figured out how those form. http://www.physorg.com/news180720809.html Biology Tue, 22 Dec 2009 16:18:18 EST news180720809 (PhysOrg.com) -- In 1996, when scientists examined a meteorite from Mars previously uncovered in Antarctica, they were intrigued by what looked like microscopic fossils of ancient Martian life forms. Now, using new technology that wasn't available 13 years ago, NASA scientists have found further evidence that the materials and structures in the meteorite are likely signs of ancient life, rather than the results of inorganic processes. http://www.physorg.com/news180264793.html Space & Earth Thu, 17 Dec 2009 09:33:52 EST news180264793 (PhysOrg.com) -- Brookhaven Lab scientists have developed a new scanning electron microscope capable of selectively imaging single atoms on a surface while simultaneously probing atoms throughout the sample?s depth. The development could greatly expand scientists? ability to understand and control chemical reactions, such as those in energy-conversion devices. http://www.physorg.com/news172746177.html Nanotechnology Mon, 21 Sep 2009 10:04:16 EST news172746177 (PhysOrg.com) -- How do you handle the tiny components needed for constructing nanoscale devices? A European consortium has built two microrobotic demonstrators that can automatically pick up and install carbon nanotubes thousands of times thinner than a human hair. http://www.physorg.com/news169738415.html Nanotechnology Mon, 17 Aug 2009 14:34:14 EST news169738415 The online gallery for Princeton University's third Art of Science competition will go live Thursday, May 14, at noon EDT. An online site that allows members of the public to choose their favorite 2009 Art of Science image will go live at the same time. http://www.physorg.com/news161528913.html Other Sciences Thu, 14 May 2009 14:08:56 EST news161528913 A piece of chalk in a laboratory at the University of Stavanger in Norway may be the key to unlock a great mystery. If the mystery is solved, it will generate billions in additional income for the oil industry. Associate Professor Merete Vadla Madland at the Department of Petroleum Engineering at the University of Stavanger is leading a group of geologists, petroleum engineers, rock mechanics, physicists, mathematicians and chemists who are now switching between modelling and experimental testing at the chalk laboratory. They are about to uncover the mechanisms behind water weakening. The answer to this riddle is crucial knowledge for oil companies to be able to predict the reservoirs` behaviour. http://www.physorg.com/news159792763.html Space & Earth Fri, 24 Apr 2009 11:53:06 EST news159792763 Scientists at the National Physical Laboratory (NPL) in Teddington have worked with the Wallace Collection to analyse the contents of Viking swords - and the results shed new light on trade routes in the middle ages. http://www.physorg.com/news150373962.html Physics Mon, 05 Jan 2009 10:32:42 EST news150373962 (PhysOrg.com) -- Scientists have discovered a way to link nanowires and other nanoobjects into complex nanostructures and circuits by fusing them together with tiny amounts of solder. The researchers, from Sheffield University in the UK, expect that their method could be used to fabricate nanoelectronic test structures for research or to repair interconnects or other defects in circuits. http://www.physorg.com/news149774354.html Nanotechnology Mon, 29 Dec 2008 11:59:14 EST news149774354
