Scientists Just Stored 52 Pages of Mozart in DNA
DNA storage could decrease our reliance on energy-intensive data centers
So much of modern life is digital that the amount of data we’re generating is quickly outpacing the amount of storage space we have for that data. Not only does this mean we may need to build more massive data centers, but it’s bad news for climate change, too. The energy needs of data centers already account for about 1% of global electricity consumption, and that will only continue to increase.
As an alternative to computer servers, scientists have been exploring the idea of storing data in synthetic DNA. A tiny smear of DNA in a test tube could conceivably hold 10,000 gigabytes of data — the equivalent of 600 basic smartphones.
But using DNA to store data isn’t practical yet because the process of making synthetic DNA in a lab, encoding it with information, and retrieving the data is expensive. San Francisco-based Twist Bioscience already offers DNA-based data storage, but CEO Emily Leproust told me last year that it costs about $1,000 per megabyte. “If you think about a big email attachment, that’s 25 megabytes, that would be $25,000,” she said. “That’s an expensive email.” Twist’s special machines print out strands of DNA with incredibly high accuracy.
