DNA hard drive coming to a gene near you

Scientists have long-known that DNA which contain the codes that living things are incredible storage devices. European scientists took that fact to heart and developed a method to encode information on tiny strands of DNA. In the journal Nature, the scientists reported that they have successfully stored all 154 of Shakespeare's sonnets on DNA.

Scientists have long-known that DNA which contain the codes that living things are incredible storage devices. European scientists took that fact to heart and developed a method to encode information on tiny strands of DNA. In the journal Nature, the scientists reported that they have successfully stored all 154 of Shakespeare's sonnets on DNA.

 

“There are more things in heaven and earth, Horatio, Than are dreamt of in your philosophy,” Hamlet tells Horatio in Scene V of Shakespeare's tragic play about the cursed Dane.

It's unlikely that the Bard would have ever “dreamt of” having all 154 of his sonnets stored in tiny bits of DNA. But that's exactly what Ewan Birney and Nick Goldman, European Bioinformatics Institute scientists have done.

According to a press release Wednesday, the storage method developed by Goldman and Birney, was explained in an article published in the journal Nature. The process allows a minimum of 100 million hours of high-definition video to be stored in about one cup of DNA.

There is a lot of digital information in the world – about three zettabytes’ worth (that’s 3000 billion billion bytes) – and the constant influx of new digital content poses a real challenge for archivists,” the scientists explained. “Hard disks are expensive and require a constant supply of electricity, while even the best ‘no-power’ archiving materials such as magnetic tape degrade within a decade. This is a growing problem in the life sciences, where massive volumes of data – including DNA sequences – make up the fabric of the scientific record.”

Goldman said it has been known for sometime that DNA is a “robust way to store information because we can extract it from wooly mammoth bones, which date back tens of thousands of years, and make sense of it. It’s also incredibly small, dense and does not need any power for storage, so shipping and keeping it is easy.”

The new method requires synthesizing DNA from the encoded information: enter Agilent Technologies, Inc, a California-based company that volunteered its services. Ewan and Nick sent them encoded versions of: an .mp3 of Martin Luther King’s speech, “I Have a Dream”; a .jpg photo of EMBL-EBI; a .pdf of Watson and Crick’s seminal paper, “Molecular structure of nucleic acids”; a .txt file of all of Shakespeare's sonnets; and a file that describes the encoding.
