Bacteria emit bleeps, bloops
Scientists make bacteria behave like computers.
Some jokes write themselves. Bacteria can blue-screen? They can can get struck by lightning, become conscious and fall in love with your girlfriend? They change from jet plane to grasshopper to construction vehicle and combine to form a Mega-Decepticon?
No, they were programmed to emit red or green fluorescent light in response to a signal emitted from another set of E. coli... "What's new about this latest effort is that the bacteria are made to communicate, so that millions or even billions of them gather in a predictable manner."
Like moths around a flame. Bacteria and people: same dumb-asses, different level of resolution.
