Biomedical engineers at Boston University have taught bacteria how to count. Professor James J. Collins and colleagues have wired a new sequence of genes that allow the microbes to count discrete events, opening the door for a host of potential applications.
"These are such basic tools that it's really hard to say what thousand things they might be used for in the future," said Ari Friedland, a graduate student in Collins' lab and a co-author of the paper. "Consider computing – what does one transistor do for you? Not that much, but if you pack a few thousand onto a chip, then you really have some power. These are fundamental biocomputing devices."
Living computers in our lifetime. Imagine that.
