bacterial photography
14 Jan

I saw this in the New Scientist:
This bacterial “photo” was created by projecting light onto bacterial “film” – genetically engineered E. coli bacteria. The film was infused with a sugar that turns black when digested. The bacteria in the dark parts of the Petri dish digested this sugar and so turned black, whereas in the illuminated areas, a light-activated gene prevented the bacteria from eating the sugar, and so these parts remained clear.
