DNA 'Lite-Brite' is a promising way to archive data for decades or longer
A simple two-dimensional grid can convey a lot of information – whether making pictures with Lite-Brite or storing data in DNA. Justin Day/Flickr , CC BY-SA The Research Brief is a short take about interesting academic work. The big idea We and our colleagues have developed a way to store data using pegs and pegboards made out of DNA and retrieving the data with a microscope – a molecular version of the Lite-Brite toy. Our prototype stores information in patterns using DNA strands spaced about 10 nanometers apart. Ten nanometers is more than a thousand times smaller than the diameter of a human hair and about 100 times smaller than the diameter of a bacterium. We tested our digital nucleic acid memory (dNAM) by storing the statement “Data is in our DNA!n.” We described the research in a paper published in the journal Nature Communications on April 22, 2021. Previous methods for retrieving data in DNA require the DNA to be sequenced. Sequencing is the process of reading the genetic ...
