Two founding texts stored on DNA and deposited in the National Archives


French researchers have digitized the Declaration of the Rights of Man and of the Citizen and that of the Rights of Women and of the Citizen.

It is still an expensive technique. But the method of storage on artificial DNA, developed by researchers specializing in algae, CNRS and Sorbonne University, is very promising. Instead of using digital media like a hard drive or magnetic tape, which consumes energy for storage, takes up a lot of space, and needs to be duplicated regularly, the researchers developed a method to record information on data. Synthetic DNA, the carrier of genetic information composed of a succession of nucleotides.

The advantages are manifold. “It is a very stable molecule which can have a lifespan of tens of thousands of years”, explains Stéphane Lemaire, research director at the CNRS. In addition, the storage density is much higher than what can be achieved with magnetic media. “It would be possible to store 47 zettabytes of data (a zetta byte is a 1 followed by 27 zeros) on 100 grams of DNA ‘
