90GB Of Data Can Now Be Stored In 1g Of Bacteria


A Transmission Electron Micrograph image of Deinococcus radiodurans, one of the world’s toughest bacteria Researchers from the Chinese University of Hong Kong have succeeded in demonstrating data storage and encryption with bacteria. While current electronic data storage methods approach their limits in density, the team achieved unprecedented results with a colony of E.coli. Their technique allows the equivalent of the United States Declaration of Independence to be stored in the DNA of eighteen bacterial cells. Given there are approximately ten million cells in one gram of biological material, the potential for data storage is huge. Furthermore, data can be encrypted using the natural process of site specific genetic recombination: information is scrambled by recombinase genes, whose actions are controlled by a transcription factor. However, the technique is not yet perfect. Retrieval of data requires a sequencer, and is therefore tedious and expensive. Additionally, toxic DNA is bound to be present…
