Over 160 years since potato blight wreaked havoc in Ireland and other northern European countries, scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) finally have the blight-causing pathogen in their sights and are working to accelerate breeding of more durable, disease resistant potato varieties. http://www.physorg.com/news169119922.html Biology Mon, 10 Aug 2009 10:45:55 EST news169119922 In a landmark technical achievement, investigators in the Vanderbilt Center for Structural Biology have used nuclear magnetic resonance (NMR) methods to determine the structure of the largest membrane-spanning protein to date. http://www.physorg.com/news165158481.html Biology Thu, 25 Jun 2009 15:10:02 EST news165158481 (AP) -- The new swine flu virus lacks genes that made the 1918 pandemic strain so deadly, a U.S. health official said Friday. http://www.physorg.com/news160406074.html Medicine & Health Fri, 01 May 2009 14:14:55 EST news160406074 (PhysOrg.com) -- Nearly a billion years ago, bacteria evolved an insidious means of infecting their hosts - a syringe-like mechanism able to inject cells with stealthy hijacker molecules. These molecules, called virulence factors, play a sophisticated game of mimicry, imitating many of the cells` normal activities but ultimately co-opting them to serve the bacteria`s needs. Now researchers at The Rockefeller University have identified a new class of these coup artists that appear to take over a key process that regulates a wide range of cellular duties, from cell-cycle progression to cell death, even communication between cells. http://www.physorg.com/news155317992.html Chemistry Tue, 03 Mar 2009 15:54:34 EST news155317992 A new research study at the University of Delaware seeks to determine why Vibrio parahaemolyticus, a microorganism that lives in seawater and is related to the bacterium that causes cholera, is expanding its range and virulence. http://www.physorg.com/news151765070.html Biology Wed, 21 Jan 2009 12:58:32 EST news151765070 Scientists have gained insight into the complex mechanisms that control bacterial pathogenesis and, as a result, have developed new theories about how independent mechanisms may have become intertwined during evolution. The research, published by Cell Press in the October 10th issue of the journal Molecular Cell, may lead to strategies for developing more effective therapeutics against the human pathogen responsible for most of the antibiotic-resistant infections contracted in the community. http://www.physorg.com/news142775112.html Biology Thu, 09 Oct 2008 12:45:12 EST news142775112 Scientists from the Universities of Bath and Exeter have developed a rapid new way of checking for toxic genes in disease-causing bacteria which infect insects and humans. Their findings could in the future lead to new vaccines and anti-bacterial drugs. http://www.physorg.com/news142764167.html Biology Thu, 09 Oct 2008 09:42:47 EST news142764167 Researchers from the Virginia Bioinformatics Institute (VBI) at Virginia Tech have identified the region of a large family of virulence proteins in oomycete plant pathogens that enables the proteins to enter the cells of their hosts. The protein region contains the amino acid sequence motifs RXLR and dEER and has the ability to carry the virulence proteins across the membrane surrounding plant cells without any additional machinery from the pathogen. http://www.physorg.com/news137086046.html Biology Mon, 04 Aug 2008 16:27:26 EST news137086046
