Researchers at The Rockefeller University in New York said they discovered two promising new antibiotics by sifting through the human microbiome with the help of a software. By using computational methods to identify which genes in a microbe's genome ought to produce antibiotic compounds and then synthesising those compounds themselves they were able to discover the new antibiotics without having to culture a single bacterium according to a study published in the journal Nature Chemical Biology. Most antibiotics in use today are based on natural molecules produced by bacteria - and given the rise of antibiotic resistance there is an
