The use of DNA as a carrier of information has been talked about for a long time. There are even quite successful developments in this area. And it seems that the future may indeed be behind this technology, as recently a group of Microsoft Research scientists together with colleagues from Twist Bioscience and the University of Washington set a new record in recording, storing and decrypting information from DNA strands.
Scientists were able to code in the DNA of Tutu jazz singer Miles Davis and Smoke on the Water of the rock band Deep Purple in a live performance, and then reproduced them with one hundred percent accuracy.
“Coding occurs by transferring information from the usual binary code (zeros and ones) to a structural DNA code (in the form of four nitrogenous bases of which DNA is composed). When reading, a reverse transcoding into binary code is performed. At the same time, the physical DNA carrier itself is smaller in size than a grain of sand. ”
As scientists emphasize, unlike other information carriers, DNA is able to safely store information for thousands of years, while regular copies have to be changed every 10 years.
“In addition to durability, DNA has an incredible capacity. About 10 terabytes of data can be stored in DNA the size of a pencil tip, which is equivalent to the memory of 600 standard smartphones, and all the digital information of the world can fit in about nine liters of this biological material. ”
Experts believe that their discovery will allow to keep all the important information for humanity intact almost forever. And the existing record will now become part of the UNESCO Memory of the World archive.
