Scientists at the University of York have discovered how certain bacteria such as Escherichia coli have evolved to capture rare sugars from their environment giving them an evolutionary advantage in naturally competitive environments like the human gut. http://www.physorg.com/news177244138.html Chemistry Thu, 12 Nov 2009 10:31:40 EST news177244138 Organisms ensure the survival of their species by genetically adapting to the environment. If environmental conditions change too rapidly, the extinction of a species may be the consequence. A strategy to successfully cope with such a challenge is the generation of variable offspring that can survive in different environments. Even though a portion of the offspring may have a decreased chance to survive, the survival of the species as a whole is guaranteed. http://www.physorg.com/news176567521.html Biology Wed, 04 Nov 2009 14:32:55 EST news176567521 A promising antimicrobial agent already known to kill bacteria can also kill viruses and stimulate the innate immune system, according to researchers at National Jewish Health. In a paper appearing online June 4 in the Journal of Investigative Dermatology, Michael Howell, PhD, Assistant Professor of Pediatrics, and his colleagues demonstrated that the synthetic compound CSA-13 can kill vaccinia virus in cell cultures and in mice. Additionally, they showed that CSA-13 stimulates cells to produce their own antimicrobial proteins. http://www.physorg.com/news163319060.html Medicine & Health Thu, 04 Jun 2009 07:25:06 EST news163319060 Aerosol delivery of antibiotics via nanoparticles may provide a means to improve drug delivery and increase patient compliance, thus reducing the severity of individual illnesses, the spread of epidemics, and possibly even retarding antibiotic resistance. http://www.physorg.com/news161955592.html Nanotechnology Tue, 19 May 2009 12:40:18 EST news161955592 Using probiotics successfully against a number of animal diseases has helped scientists from University College Cork, Ireland to understand some of the ways in which they work, which could lead to them using probiotics to prevent and even to treat human diseases. http://www.physorg.com/news157869202.html Biology Thu, 02 Apr 2009 05:34:45 EST news157869202 From hair color to the ancestral line of parasitic bacteria, scientists can glean a lot from genes. But imagine if genes also revealed where you lived or who you spent time with. It turns out they do, if you know where and how to look. http://www.physorg.com/news154786845.html Biology Wed, 25 Feb 2009 12:25:31 EST news154786845 Scientists have discovered a new way for bacteria to transfer toxic genes to unrelated bacterial species, a finding that raises the unsettling possibility that bacterial swapping of toxins and other disease-aiding factors may be more common than previously imagined. http://www.physorg.com/news150481769.html Medicine & Health Tue, 06 Jan 2009 16:29:29 EST news150481769
