Scientists at Columbia University have used a modified CRISPR system in order to write information into the DNA of living bacteria. Specifically, the researchers used a CRISPR-based cellular recorder as well as E. coli bacteria which significantly change their genomes when a voltage is applied. The genomic patterns “Power on “ and “Power off” correspond to the binary “1” and their absence “0”, which are used in digital computers. The research team demonstrated its new method by encoding the message “hello world!” into the bacteria.
