Researchers have found living together the known carrier species for the Chagas disease-causing parasite Triatoma dimidiata (also known as "kissing bugs") and a cryptic species that looks the same - but is genetically distinct from - the known carrier species. The two species haven't interbred for as many as 5 million years, according to a report published March 10 in the open-access journal PLoS Neglected Tropical Diseases. http://www.physorg.com/news155887016.html Medicine & Health Tue, 10 Mar 2009 06:57:47 EST news155887016 The thriving use of private military contractors in place of citizen-soldiers allows nations to externalize the costs of war and outsource accountability during wartime, according to sociologist Katherine McCoy, writing in the winter 2009 issue of Contexts magazine. http://www.physorg.com/news155817145.html Other Sciences Mon, 09 Mar 2009 11:32:57 EST news155817145 (Physorg.com) -- Although ecologists expect many species will be harmed by climate change, some species could be buffered by their potential to evolve or by changes in their surrounding ecosystems. http://www.physorg.com/news155490287.html Biology Thu, 05 Mar 2009 15:45:23 EST news155490287 (PhysOrg.com) -- To understand friction on a very small scale, a team of University of Wisconsin-Madison engineers had to think big. http://www.physorg.com/news154790620.html Nanotechnology Wed, 25 Feb 2009 13:24:33 EST news154790620 Deep-sea drilling into one of the most active earthquake zones on the planet is providing the first direct look at the geophysical fault properties underlying some of the world's largest earthquakes and tsunamis. http://www.physorg.com/news153919676.html Space & Earth Sun, 15 Feb 2009 11:28:23 EST news153919676 (PhysOrg.com) -- A little more than a year after University of Wisconsin-Madison scientists showed they could turn skin cells back into stem cells, they have pulsating proof that these "induced" stem cells can indeed form the specialized cells that make up heart muscle. http://www.physorg.com/news153679352.html Medicine & Health Thu, 12 Feb 2009 16:42:59 EST news153679352 (PhysOrg.com) -- A hallucinogenic compound found in a plant indigenous to South America and used in shamanic rituals regulates a mysterious protein that is abundant throughout the body, University of Wisconsin-Madison researchers have discovered. http://www.physorg.com/news153670865.html Chemistry Thu, 12 Feb 2009 14:21:51 EST news153670865 The ability to empathize with others is partially determined by genes, according to new research on mice from the University of Wisconsin-Madison and Oregon Health and Science University (OHSU). http://www.physorg.com/news153549608.html Medicine & Health Wed, 11 Feb 2009 04:42:56 EST news153549608 (PhysOrg.com) -- Molecular and cellular biologists have made tremendous scientific advances by dissecting apart the functions of individual genes, proteins, and pathways.
