Fine Reading: Evolution of Pathogen Tolerance

by Roberto | While reading a review yesterday, I recalled a conversation I had with a student nearly forty years ago. He did not appear interested in the subject of my lectures – bacterial genetics and physiology – so I was curious to know the reasons why. Read more →
