Their hypothesis is that primordial ribosomes were self-replicating intermediates between the prebiotic world and the […]
There is a widespread concern about the increasing antibiotic resistance and the limited new drugs to treat infectious diseases, as discussed in a previous post . Consequently, the discovery of a new antibiotic active against a range of bacterial pathogens including Staphylococcus aureus has been greatly welcome, especially because no resistance to it has been […]
