In today's issue of Science ($): A review article from Christophe Fraser and colleagues looks at alternative approaches to defining bacterial species. The team used computer simulations of speciation in an attempt to provide more accurate categorization of bacteria. A paper from Chava Kimchi-Sarfaty et al. at the US National Cancer Institute presents findings that a SNP previously considered "silent" is in fact linked to altered function of the MDR1 gene. And in a perspective piece for that paper, Anton Komar from Cleveland State University writes about the "silent but not invisible" SNPs.
