Scientists at European Bioinformatics Institute (EBI) are using synthetic DNA to solve the worlds long-term data archival problem. With billions upon billions of bytes occupying hard drives and using electricity - scientist have narrowed their sights on DNA as a viable storage solution. DNA has the capacity for high-density information encoding, and its has longevity - think about it, we can extract DNA from the bones of prehistoric creatures, that pretty good storage performance (minus a hard drive and electricity). Consider this, DNA can encode roughly 2 Petabytes per
gram, now that's serious storage.
Recently the scientists at EBI, encoded Martin Luther King's 1963 "I have a dream" speech, along with all 154 of Shakespeare's sonnets, into a string of DNA - then they retrieved the data with 100% accuracy, using new error correction techniques, which did not previously exist.
Some day DNA may provide the solution for our long-term data archival needs, but for now keep your hard drives spinning.
