Scientists discover a gene in anthrax-causing bacteria may help defend against this form of bio-warfare. http://www.physorg.com/news171628177.html Biology Tue, 08 Sep 2009 11:40:01 EST news171628177 Adult stem cells and their more committed kin, progenitor cells, are prized by medical researchers for their ability to produce different types of specialized cells. The potential of using these cells to repair or replace damaged tissue holds great promise for cancer therapies and regenerative medicine. However, the question that must first be answered is what determines the ultimate fate of a stem or progenitor cell? A team of researchers led by Berkeley Lab's Mark LaBarge and Mina Bissell appear to be well on the road to finding out. http://www.physorg.com/news154954632.html Biology Fri, 27 Feb 2009 10:57:50 EST news154954632 Researchers have put forward a simple model of development and gene regulation that is capable of explaining patterns observed in the distribution of morphologies and body plans (or, more generally, phenotypes). The study, by Elhanan Borenstein of the Santa Fe Institute and Stanford University and David Krakauer of the Santa Fe Institute was published in this month's issue of PLoS Computational Biology. http://www.physorg.com/news144039438.html Biology Fri, 24 Oct 2008 03:57:18 EST news144039438
