The evolution of multiple antibiotic resistances is a global and difficult problem to eradicate. Isabel Gordo, a group leader at the Instituto Gulbenkian de Ciência (IGC), Portugal, reports in the paper published in the latest issue of PLoS Genetics, that the deleterious effect associated with the acquisition of resistance by a bacteria can be suppressed by the acquisition of a new resistance to another antibiotic. These findings have direct implications for the approaches taken to tackle the problem of multi-resistance to antibiotics and in the choice of antibiotics to be administrated to patients. http://www.physorg.com/news167633283.html Medicine & Health Fri, 24 Jul 2009 05:50:02 EST news167633283 (PhysOrg.com) -- Researchers studying the behaviour of the stunningly coloured Gouldian finch have made an exciting discovery - females of the species deliberately overproduce sons when breeding with a male of a different head colour. http://www.physorg.com/news156706578.html Biology Thu, 19 Mar 2009 18:38:17 EST news156706578 Animals have an astonishing ability to develop reliably, in spite of variable conditions during embryogenesis. New research, published in parallel this week in PLoS Biology and PLoS Computational Biology, addresses how living things can develop into precise, adult forms when there is so much variation present during their development stages. A team led by John Reinitz at Stony Brook University, and funded by the National Institutes of Health, shows how fruit fly embryos can "forget" initial incorrect versions of their body plan and develop into recognizable adult flies. http://www.physorg.com/news155888495.html Biology Tue, 10 Mar 2009 07:24:48 EST news155888495 Think researchers know all there is to know about Escherichia coli, commonly known as E. coli? Think again. "E. coli has more than four thousand genes, and the functions of one-fourth of these remain unknown," says Dr. Deborah Siegele, a biology professor at Texas A&M University whose laboratory specializes in carrying out research using the bacterium. http://www.physorg.com/news137301112.html Biology Thu, 07 Aug 2008 04:11:52 EST news137301112
