Solving the problem of providing compact anddurable data storage systems is one of the most important tasks for modern science. Developers from Microsoft in partnership with researchers from the University of Washington presented a system for storing digital data in DNA. A fully automated system was introduced for the first time. If this technology is successfully implemented, it will be possible to significantly reduce the amount of digital data storage.
During prototype testing, developersMicrosoft recoded from the binary system into DNA codes the simple word HELLO. The device translated the bits (1 and 0) into a DNA sequence (A, C, T, G), synthesized the molecule and stored it as a liquid. Using special techniques, the DNA chain was later decoded into binary bits. The process of converting digital information with a volume of 5 bytes into DNA codes and reverse decoding, however, took about 21 hours. Microsoft assured that there is already a technology that reduces the time to 10-12 hours.
From synthesized by scientists DNA weighing 1 mg weight"HELLO coded word" was 4 μg. The developers claim that such digital data storage density is an order of magnitude higher than the currently used data storage methods. So the information of a large data center will fit in the size of several dice.
Under the right conditions, DNA may exist.much longer than modern archival storage technologies that have been destroyed for decades. Thus, some DNA was preserved in the tusks of the mammoth and the bones of early people in far from ideal storage conditions for tens of thousands of years.
The main task of modern scientists is to reducecost of installations to automate the process of storing data. The first commercial storage system Microsoft promises to create in the next two years. For example, the presented prototype is estimated at $ 10,000.
