In an article published in 2016 in the journal BioMed Research International, researchers found that DNA can store information for a longer time, up to about 425,000 years, while requiring much less energy and lower temperatures than conventional hard drives.
Hundreds of megabytes of data have been encoded by DNA in recent years by scientists. But more recently, not only have the media been perfectly stored in the synthetic variant of the genetic instructions that make up the whole organic life, but the archived data files have also been recovered individually without error. And this thanks to the advance research scientists from the University of Washington and Microsoft, which announces for 2020 the establishment of a data center based on DNA, titled NAM, (nucleic acid memory) in its cloud.
In the years to come some individuals will probably be able to sell, or be robbed of some samples of their DNA, in the design to transform them into nucleic acid memory. Unless, the hundreds of thousands of people who voluntarily provide samples of their DNA to companies for the purpose of researching their ancestral lineages become themselves products of consumption whose genetic data could even be pirated by cyber criminals.
DNA used as synthetic memory would store all the world's movies in a storage device no bigger than a cube of sugar, and one could store all the information of the world in a shoe box. Scientists are no longer working "only" with four nucleotide bases, namely
A, G, C and T, but with a new six-nucleotide DNA, which has additional X and Y nucleotides. This could in the long run, help to store probably all the information in the world on a device no bigger than a grain of sand and have space remaining.
Organic DNA (deoxyribonucleic acid) is encountered studying the genes that make up living organisms. Large amounts of information are stored there for a long time. A 45,000-year-old human femur was sequenced or decoded a few years ago. Synthetic DNA in the other part, is an attractive storage medium because it can theoretically store 10 million times more data than magnetic tape in the same volume and survives for hundreds of thousands of years. Ultimately, if in general men deposit their DNA wherever they go, it is also true that social life usually easily corrupts this DNA by the DNA of other humans or even animals. e.g. After drinking in a glass, the latter would have to be picked up by a waitress or waiter who in turn would deposit his DNA as well as those responsible for washing dishes. If, in general, human interaction helps to mask individual DNAs, this is not the case when someone expressly have its DNA samples taken, or when forced by the police, to submit DNA samples even during routine checks. In the United States from now on a law gives the right to the police to take the DNA samples on peoples suspected in a crime.
Once these DNAs are collected they are stored in databases, and users who claim to have their human genome deleted from these databases have rarely been successful.
