Bacteria Save Your Data, Make Multiple Backups
Artificial DNA with encoded information can be added to the genome of common bacteria, thus
preserving the data. The technique was developed at Keio University Institute for Advanced
Biosciences and Keio University Shonan Fujisawa Campus. If you think flash thumbdrives are small, check this data storage out.
According to researchers, up to 100 bits of data can be attached to each organism. Scientists successfully encoded
and attached the phrase "e=mc2 1905" to the DNA of bacillus subtilis, a common soil
new archival storage medium - Bacillus subtilis)
One early use for the technique would be to create special markers to identify legitimate versions
of pharmaceuticals. However, the bacillus itself creates new copies of the data every time it
reproduces itself, thus making it an ideal archival storage system.
Bacillus subtilis also creates extra copies of the data, inserting it in different places in
its genome, further safeguarding the data. That's "multiple backup copies" for those of you who
have lost data in the past.
The first time I read about this idea was in an excellent series of fantasy novels by Barbara
Hambly. In her 1982 Darwath trilogy, she writes about how wizards of several thousand years ago
succeeded in tying information to the DNA of selected individuals. In the story, several people
from 1980's California find themselves transported across the Void to another planet and the Realm
of Darwath. They face a deadly species of queerly magical beings - the Dark - who destroyed civilization thousands of years ago. Everything that was made of paper (like books and records) were burned to stave off attacks by the Dark. Tying memories to a few suitable bloodlines was the only way to preserve a record of that period that would endure.
