Scientists Make Micro-Bricks

Digital Trends reports, "Scientists have used genetically engineered bacteria to recreate a masterpiece at a microscopic scale. By engineering E. coli bacteria to respond to light, they’ve guided the bacteria like tiny drones toward patterns that depict Leonardo da Vinci’s Mona Lisa." Researchers did this to show the public that E. coli bacteria are engineered organisms that can be used as “microbricks” and living propellors.
