I don’t write about science and medicine enough here, which is a pity, but I do want to emphasize the promise this new discovery carries. For a long time, scientists have been warning us that microbes are evolving resistance to existing antibiotics. Unnecessary use of antibiotics, in humans and animals, speeds up the advantage of microbes in the ongoing arms race of antibiotic resistance. This latest discovery is very good news, because it shows a new way to develop antibiotics, in addition to showing a specific new antibiotic that apparently is effective against the fearsome MRSA.
