Scientists at Tufts University have refined a method acting that allow masses to send message using fluorescent stress of Escherichia coli . There ’s enough color combination to encode the full alphabet , the number 0 to 9 and a few symbolization .
The operation , called steganography by print array of microbes ( SPAM ) , set out in the lab where the bacteria are arranged in coloring - tantalize messages and grown on a petri dish . The cultures are then transferred to a thin film that can be station to someone else . The subject matter is discover when the recipient grows the bacteria in a fresh petri dish . And you’re able to do so much more if you add in other genetical limiting .
According to inquiry lead David Walt , scientists can make a self - destructing message by using fluorescent bacteria that lose their glowing after a certain amount of time . Even antibiotic resistive strain can be used to add a security measure to a subject matter . These strain call for the recipient to add the right antibiotic to decode the message . If the faulty one is added , the ensue message would be gibberish .
It ’s a wide-eyed , yet brilliant system that Walt say could lead to “ all sort of clandestine undercover agent diligence . ”http://ase.tufts.edu / chemistry / walt … [New Scientist ]
