Researchers in the UK and Canada have succeeded in creating the world's first text message via a molecular communication. The messages are encoded in molecules of alcohol, which are then wafted across the room to a receiver, which sniffs the molecules out of the air and decodes the message. Molecular networks are an area of interest for applications and environments where the usual method of wireless communication -- electromagnetic radiation -- can't be used, such as underwater, underground, in oil pipelines, or inside your body.
