I don't like to think much about what's lurking up my nostrils, but scientists have just found a new class of antibiotics in naturally occurring bacteria that live in human noses.

Humans carry millions of bacteria, and some of us are home to Staphylococcus lugdunensis. These bacteria produce their own weapon against competing bacteria species - a chemical scientists have named lugdunin.

In a study on mice lugdunin successfully treated MRSA, a really nasty bug that's hard to kill. Let's hope one day it could be a new antibiotic for humans.

It will probably take years to find out if lugdunin will work in humans.
