R&D: One-Step Storage in Cellular DNA
Researchers attempting to exploit natural benefits of cellular DNA by modifying cells to store information that would otherwise be maintained in digital form

Abstract: “The cumbersome encoding of digital data to cellular DNA hinders the use of cells as living hard drives. A new approach transfers digital information directly into cellular DNA by converting electrical signals into stable and interpretable changes in the genomes of bacterial populations. DNA has been used by living systems to reliably store and propagate information longer than any other medium on Earth. It is durable, high density, and easy to copy. These beneficial properties are amplified inside a cell, which actively repairs and copies its genomic DNA. Now, researchers are attempting to exploit the natural benefits of cellular DNA by modifying cells to store information that would otherwise be maintained in a digital form.“
