Your Nose May Have Drugs in It, the Antibiotic Kind

The human nose is a battleground for bacteria and some of them could prove to be our allies. Researchers have discovered a new antibiotic, produced by nose-dwelling bacteria, that kills antibiotic-resistant superbugs, including MRSA. The study, published in Nature, shows that the human microbiome -- the microorganisms living on and within us -- could be an important source for new antibiotics, desperately needed as infectious bacteria become resistant to our current antibiotic drugs.
