Researchers developed bacteria that can create images

Researchers at MIT have engineered bacteria to sense red, green, and blue light — and then create a picture of what they've "seen," like the arrangement of fruit pictured above, by expressing pigments in those colors.

"At the most fundamental level, we've given E. Coli the ability to detect different kinds of light and then compose an image," says genetic engineer Felix Moser. "It's a demonstration that synthetic biology tools have come a long way in the last decade."
