Bacterial Slime Acts As Teensy Eyeball

Slimy microbes called cyanobacteria use their teensy bodies as lenses to collect light and "see," before growing little legs to inch toward those rays, new research suggests. "The idea that bacteria can see their world in basically the same way that we do is pretty exciting," study lead author Conrad Mullineaux, a microbiologist at the Queen Mary University of London, said in a statement. Cyanobacteria, or blue-green algae, are some of the most ancient life-forms on the planet.
