Engineer Robert Grass revealed, hard drives and storage of physical information, such as books, will be worn by time. Quoted Science Alert, Grass describes his journey in discovering methods of information storage that survived for millions of years. The secret is in the DNA.
In 2012, researchers showed that you could translate one megabyte (MB) of information in the form of DNA, and read it again. DNA has its own language, and dropped into the sequence of nucleotides (A, C, T, and G). Similar to binaries, which solves the information in zeros and ones.

DNA has the advantage that can contain vast amounts of information in a small size. In theory, one gram of DNA can carry 445 exabytes of information. All of this "is enough to store all the data owned by Google, Facebook, and all the giant technology company, with the rest of the room."
However, the problem with previous DNA studies, is the lack of stability of information over time, which is a crucial factor, according to Grass.
Now, Grass and her co perisetnya Reinhard Heckel, both from ETH Zurich, Switzerland, offers a method that is not only potentially save all the content of Wikipedia or Facebook, but also to save forever.
Grass received information from fossils, where the DNA is stored very stable animals (such as the discovery and study dinosaurs). DNA can rot if exposed to water and oxygen, but by storing artificial DNA in a glass container, Grass could avoid damaging it.
Even so there is no perfect method of storage, this moment where Heckel intervene. Heckel came up with the idea of adding repetitions in DNA, so that some information is missing, it can be returned.
Both expose the capsules contain information on tests that replicate the conditions of 500,000 to one million years in cold storage cabinet, and the data persist.
However, the discovery has not finished here. Next is looking for storage space capsule.
