For a study published in the journal Science, scientists from Harvard and the Technion-Israel Institute of Technology set up a really big petri dish—60 by 120 centimeters (2 by 4 feet), to be exact. In it, they placed antibiotics at varying levels. With no antibiotics on the outer edge, the antibiotic dose got higher and higher until the center, where it hit 1,000 times the concentration at which bacteria can usually survive. Then, they added E. coli bacteria, set up a camera, and watched. (You can watch, too, in the video below).
