According to researchers, they are approaching a technology, which is expected to store digital data for thousands of years. They put the data on microscopic strands of DNA. The information has been revealed by a group of researchers at a meeting of the American Chemical Society.

They reported that they showed information on DNA that lasted 2,000 years in storage and there were no errors in retrieval and decoding of the data. They imitated the passage of centuries by entrenching the DNA in spheres of silica and increasing their temperature to 160 degrees Fahrenheit.

It is equal to about two millennia at 50 degrees, the researchers said. They added that the data was complete when it was retrieved and decoded.

According to the researchers at the Swiss Federal Institute of Technology in Zurich, they've effectively encoded audio, images and video using the DNA technique. They added that the long-term storage technique has room for anything that could be recorded as digital binary code.

According to them, storing is required in very compact form and for a long time because digital technology leads to creation of increasingly huge amounts of data.

According to researcher Robert Grass, "A little after the discovery of the double helix architecture of DNA, people figured out that the coding language of nature is very similar to the binary language we use in computers. On a hard drive, we use 0s and 1s to represent data". He said that when it comes to DNA, there are four nucleotides A, C, T and G.
