Absolutely fantastic media created by specialists from the Harvard Medical School. This kind of "Hard Disk", which is not inferior to his brother on the characteristics of the modern records data using DNA!
There is no doubt that any living organism already has its own repository of information in the form of DNA. Biological superiority "hard disk" is just huge density of stored information. In addition, as a joke, scientists, DNA has been used for about 3.5 billion years, which is the best proof of its effectiveness.
Engaged in the development of data storage technology using DNA experts from Harvard Medical School (Harvard Medical School) wrote a book written by them in the biological medium.
Dubbed "Regenezis: how synthetic biology can help to rethink the nature and themselves» (Regenesis: How Synthetic Biology Will Reinvent Nature and Ourselves), the book contains the authors' appeal to the public carefully monitor the formation of synthetic biology, producing the rules for its implementation and dissemination.
The process of writing (encoding) of the book stemmed from the use of the "draft" in the HTML format using a special program. The text and images have been converted from the binary system in the Quaternary, where the nucleotides A and C responded to zero, and G or T unit.
All data were divided into 96-bit data blocks, wherein the address bit stream 19 had a length in characters from 0000000000000000001. Total volume was 54898 book data blocks, each of which represents a separate DNA strand.
After the book was written on a biological medium, the experts had recurrent coding to test the record for errors. The result was a more than decent: two errors per million bits per megabyte file of 5.27, which is only a few typographical errors in the final text.
To solve the problem of preserving data creators abandoned the use of living cells, which can remove chunks of data "discretion". Instead, scientists have used chemically synthesized molecules enclosed in a tiny glass chip.
"The density of the recorded information and the amount of stored data are comparable with other recent developments in physics — says one of the scientists Sriram Kosuri (Sriram Kosuri). — However, DNA chips do not require any special storage conditions, such as low temperatures. DNA is stored in the indoor environment. "
Admiring the potential strands that carry genetic information scientist noted that the amount of data contained in a single molecule of DNA is truly enormous: one gram of a substance capable of storing the volume of information produced by mankind over the year.
A detailed report on the work done developers DNA-ROM published in the journal Science.
