"DNA-based memory devices are not optimal for recording analog information, such as the magnitude of inputs over time. Farzadfard and Lu converted genomic DNA into a “tape recorder” within living bacterial populations (see the Perspective by Ausländer and Fussenegger). Specific DNAs were used to introduce precise mutations into genomic DNA. The stored information could be read out via reporter genes, functional assays, and DNA sequencing. This approach allowed the memorization of multiple inputs at the population level. The record could also be erased when required." See commentary @ Science and Full article.
