“What you’re offering by [encoding digital data as DNA] inside the cell is the machinery the cell has to protect its DNA.”
– Harris Wang
, system biologist at Columbia University, on successfully inserting binary code for “hello world!” into the DNA of living E. coli bacteria using CRISPR. In their paper
, Wang and team claim that, compared to other DNA-based data-storage methods that rely on in vitro synthesis, in-cell encoding can maintain information over many generations in natural open environments.
