  1. Even pathogens hate a cheater

    I would like to apologize for the long delay since my last post. The excuse (I keep telling myself) is that, having already written too many computational articles, it was time to prove that I could write about biology too. Unfortunately I’m not nearly as good at reading the literature as I should be. Anyway, it’s done. You can stop complaining now.

    One barrier to engineering bacteria for biofuel production or any other human endeavor is that evolutionary rates are scaled by population sizes and growth rates. For an organism with massive population sizes (trillions of individuals or more) and doubling times on the order of hours, evolution can occur quite quickly. Genetic variants within the population which are capable of growing faster will quickly take over. For an organism which is, for example, wasting a huge fraction of its energy producing your future gasoline, you can bet …
