In Switzerland, found a way to store information in DNA million years

A group of scientists from ETH Zurich has proposed a method of storing digital data in the DNA, which, presumably, will extract the encoded information in a million years. To do this, the researchers placed the molecular chains in the quartz beads.

Over the past few years has been done more < / a> works in the field of recording and subsequent reading of information from DNA molecules. However, as says Robert Grass , one of the participants of this project " These approaches were unreliable because it does not provide error correction, and provides a method of long-term storage of molecules ».

In this work, the scientists were able to synthesize the DNA molecule, in which information is recorded with redundancy method Рида-Соломона, and to include these in a quartz bead chain. In addition to quartz experienced scientists and other methods of storing DNA, but it is best shown themselves these balls. Within a month, copies were subjected to temperatures of 60-70 degrees and different levels of humidity.

After examining the state of the samples, scientists have calculated approximately that if kept at a temperature of permafrost -18 ° C (for example, in the всемирном semenohranilische ), then the information could be read without loss even in a million years.
