By developing "synthetic" classes of teixobactin, scientists in the UK have created a "game-changing" antibiotic which could save millions of lives worldwide from drug-resistant superbugs. The new antibiotic was used to kill methicillin-resistant Staphylococcus aureus - a so-called superbug known as MRSA, which is resistant to several widely used antibiotics - in a study on mice. These synthetic forms of teixobactin can be kept at room temperature making global distribution of the drug much easier.
