Our problems and risks are huge, but so are our capabilities.
Scientists have inserted DNA-based nanobots into a living cockroach, which are able to perform logical operations. Researchers say the nanobots could eventually be able to carry out complex programs, to diagnose and treat disease.
The nanobots can interact with one another, and were shown to be able to perform simple logical operations, for example releasing a molecule stored within upon command. Or, as the researchers put it: “The interactions generate logical outputs, which are relayed to switch molecular payloads on or off.”
