A new CRISPR system-based technology enables the recording of digital data, like those presenting successive frames of the movie of a galloping horse, one of the first made ever, in a population of living bacteria. In the future, this molecular recording device could allow researchers to have cells record the key changes they undergo during their development or exposure to environmental or pathogenic signals.
