Swiss scientists have discovered new way of preserving data encoded it in DNA form, for millions of years.

As reported by Gigaom, researchers initially turned data into and then retrieved it. But the problem was it degraded too quickly to be useful as a long term storage device.

Later, the researchers found out the solution to it. By chilling down DNA and fossilizing it, the DNA encoded with data can last for millions of years. This discovery of fossilizing the DNA was made when scientists discovered a woolly mammoth in Siberia in 2013, they were surprised to find the 40,000 year old fossil well preserved in the icy conditions of that region. Scientists were able to extract long strands of DNA from the fossil that gave them hope that someday they could clone the extinct beast.

The researchers team achieved, the natural years old fossilization by encasing strands of DNA in glass. Scientists stored the glass pods at around 50 degrees Fahrenheit and accurate data could still be extracted from it up to 2,000 years later. And at 0 degrees, it can survive up to 2 million years.

Just a single gram of DNA can hold up to 455 exabytes of data. One exabyte equals 1 billion gigabytes. This new research might help preserve massive data for millions of years.
