My recent piece on Slate about E. coli, evolution, and germ warfare is now on their podcast. You can listen to it with this embedded player below, or grab the mp3 file. It is very weird to hear someone else read my words. I feel like a teacher is using me as an example of how not to do last night's homework. Nevertheless, I plan on recording some of my own previews of Microcosm between now and the publication date. Stay tuned.
