With the help of the gene editor CRISPR, scientists can now save videos in DNA, Nature writes. The researchers encoded five grayscale images into 104 DNA fragments per image, each made up of 33 DNA letters. One image per day was then introduced to the Escherichia coli bacterium. Because CRISPR adds DNA snippets to its host genome in sequential order, researchers were able to recover the recorded images after sequencing and put them together to see the movie.
