Researchers at Columbia University and the New York Genome Center (NYGC) have found an algorithm designed for streaming video on a cellphone can unlock DNA's storage potential by squeezing more data into its four base nucleotides.
They say DNA is an ideal storage medium because it is ultra-compact and can last hundreds of thousands of years if kept in a cool, dry place.
The researchers compressed the information from six sources into a master file, and then split the data into short strings of binary code. They then used an erasure-correcting algorithm called fountain codes to randomly package the strings into droplets, and mapped the ones and zeros in each droplet to the four nucleotide bases.
The researchers showed the coding strategy packs 215 petabytes of data on a single gram of DNA, 100 times more than previous methods.
