By Paul Marks BACTERIA in the bloodstream might sound like a health no-no, but they could be used to send messages between cancer-fighting nanobots.

But one machine can’t defeat a tumour single-handedly; it needs some way of telling the others to swarm on the target. Radio signals won’t travel through a liquid,
