Encoding text with GM bacteria

By at 3:14 pm Thursday, Sep 29

Science Now reports on a project from David Walt (Tufts) and George Whitesides (Harvard) to come up with a steganographic text-encoding scheme that uses bacteria to encode messages and selective antibiotics to reveal them. It was conceived of in response to a DARPA challenge to devise non-electrical text-encoding, but its applications include adding text-based information to GM crops that can be read in the field (or in the market) to determine what’s being grown.
