Cancer-fighting robot bacteria

This story is a week old, but it is so cool I wanted to posted it. Like the guy who wanted to use a modified rabies virus to track neural pathways, another mad scientist wants to re-purpose living bacteria into tiny cancer-killing machines:

Neil Forbes of the University of Massachusetts Amherst has received a four-year grant of more than $1 million from the National Institutes of Health to research killing cancer tumors with Salmonella bacteria. Forbes turns the bacteria into tiny terminator robots that use their own flagella to venture deep into tumors where conventional chemotherapy can’t reach. Once in place, the bacteria manufacture drugs that trigger cancer cells to kill themselves.

Although this therapy is purely experimental and only for treating cancer, it users in a new wave of medical bioscience based on the creation of custom symbiotes. I can only imagine that psychic brain-cotrol worms are only a few years off...
