COVER The plague doctor in clothing worn to protect from contagion, circa 1656. We are haunted by images of the horrors of disease and death, but with the current influx of data from microbial genomes, we can expect some answers to questions about how microorganisms have evolved, causing much fear. Apart from using these data to design new drugs and vaccines, we can also explore what the molecular signature of a microorganism may mean to a host population and predict more precisely the effects of intervention. 1089 [Image: Stock Montage]
