New study is an advance toward preventing a ‘post-antibiotic era’

UCLA biologists identify drug combinations that may be highly effective at reducing growth of deadly bacteria

A landmark report by the World Health Organization in 2014 observed that antibiotic resistance — long thought to be a health threat of the future — had finally become a serious threat to public health around the world. A top WHO official called for an immediate and aggressive response to prevent what he called a “post-antibiotic era, in which common infections and minor injuries which have been treatable for decades can once again kill.” (more…)

Silent mutations speak up

University of Utah researchers find that multiple silent mutations greatly impact protein translation

So-called silent DNA mutations earned their title because, according to the fundamental rules of biology, they should be inconsequential. Reported on June 5 in PLOS Genetics online, University of Utah researchers experimentally proved there are frequent exceptions to the rule. The work was conducted in the bacteria, Salmonella enterica, used to study basic biological mechanisms that are often conserved in humans. (more…)
