Microsoft specialists in cooperation with researchers from the University of Washington have successfully completed the process of translating digital information into DNA and back. Such a technique is not the first time scientists practice, but unlike previous experiments, the technology Corporation managed to fully automate the process. In the future, this can significantly reduce the volume of conventional drives and the size of data centers.
During the first launch, Microsoft successfully translated the word HELLO into an unusual format. The device encoded bits (1 and 0) in the DNA sequence (a, C, T, G), synthesized the molecule itself and stored it as a liquid. The stored DNA was then decoded back into bits after being treated with special reagents. The encryption and subsequent decryption of the record volume 5 bytes the device has spent 21 hours, but the researchers said that they found a way to cut the time down to 10-12 hours.
In nucleotide form, the" liquid "version of the word HELLO "took" only 4 µg from approximately 1 mg of synthesized DNA. According to experts, this method will fit all the information stored in a large data center into a drive the size of a few dice. There is also high reliability of such "disks": as Microsoft points out, some DNA samples were preserved for tens of thousands of years — for example, in mammoth tusks.
Currently, researchers are working to reduce the cost of equipment for automated recording of information in DNA. Earlier it was reported that the Corporation plans to create a system of information storage based on DNA by the end of this decade.
