Data encoded on DNA could last 500 years! Check out a new DNA decoder that can read data at 330 gigabits per square centimeter
Years ago, the world marveled as it recognized that more human information was created on the internet than had been written in thousands of years of human history. But with the information age growing more complex by the day, we may have to look at new ways of storing information, and it turns out the DNA we’re made of might hold the key to the ultimate organic hard drive.
A team of scientists has developed a new way of storing data, using pegs and pegboards composed of DNA, which can be retrieved via microscope, in a molecular variant of the traditional Lite-Brite, according to a recent study published in the journal Nature Communications.
The prototype can store information in DNA strands with a 10-nanometer space between them. This distance is less than one-thousandth of the diameter of a human hair, and roughly one-hundredth the size of a living bacterium.
The team tested a digital nucleic acid memory (dNAM) with the storage of a simple statement: “Data is in our DNA/n.” Earlier attempts to retrieve data stored in DNA called for DNA sequencing, which involves reading the genetic code of DNA strands — which is a critical tool in biology and medicine, but not very efficient for DNA memory.

Using a microscope, the team imaged hundreds of thousands of DNA pegs in one recording, allowing for an error-correction algorithm to retrieve all data. Once all of the bits were organized via algorithms, the prototype DNA decoder could read data at 330 gigabits per square centimeter. While this technology likely won’t show up in smartphones or laptops in the near future, DNA storage has incredible potential for archival use. In case you missed it, DNA evolved to store unconscionable amounts of data. If we knew how, our genes could store all of the emails, tweets, songs, photos, films, and books that ever existed in a DNA volume the size of a jewelry box.
