Microbe-archaea can become an eternal data carrier (2 photos)


Storage developers are located inthe constant search for media capable of storing information for as long as possible, without the risk of loss or damage to the media. One way to store data is to record information in the DNA of living organisms. The study and testing of such a technique is carried out at Harvard University, where the possibility of using the microbe Halobacterium salinarum as a DNA carrier is being investigated. The idea was proposed by the artist and philosopher Joe Davis.

Preservation of DNA in two data setswill be checked for several years. Based on the information received, specialists will try to give an answer about the suitability of using unusual microbes as an “eternal” information keeper.


The earlier method of using DNA for recordingInformation was not widely disseminated, since during the mutation of a living organism, the DNA chain underwent changes and the information was lost or distorted. However, Davis suggested using an archaea microbe as a carrier, the main property of which is the ability to stop functioning when it is placed in a salt-saturated environment.

The microbe falls into a kind of suspended animation, ceasing to mutate and develop until the salt concentration in the solution decreases.

To work on the use of class microbesarchaea as information carriers, with a guarantee of data safety for millennia, it is required to carry out numerous more tests and experiments that will stretch for years. In the first test on the DNA of the microbe Halobacterium salinarum, a three-dimensional model of the needle and egg was preserved. Thus, scientists associate the eternal storage of data with elements from the tale of Koschey the Immortal, who safely saved his life in an egg at the end of a needle.
