Scientists get store 215 petabytes in a gram of DNA


Many are the teams of scientists who continue to work to develop a new storage platform that will allow us one much greater capacity. One of the possibilities is to use DNA to store large amounts of data and now a team of researchers from Columbia University, as they have been published in EU, seems to have taken a very important step.

He has apparently been design, implement and test successfully an new algorithm able to transmit live video on mobile taking advantage of the possibilities afforded today DNA storage system that many engineers do not hesitate to qualify as a near-perfect storage system.

This new methodology allows you to store up to 1.6 bits on each nitrogen base DNA.

To carry out this project, team makes binary data nitrogenous bases to subsequently read these databases using the Fountaine Code algorithm. Thanks to this technique, for the time being, you can store up to 1.6 bits in each nitrogenous base, a number that is far superior to all previous methodologies and that is very close to the theoretical limit of 1.8 bits.

If we put all these data in perspective and make a case to the calculations of the researchers responsible for the project, we find that this project is capable of storing no less than 215 petabytes in each gram of DNA making it, so as it has been identified, it would result in denser storage ever made by man support.

In statements by Yaniv Erlich, Professor of computer science at Columbia University and co-author of the proyectro:

DNA does not degrade over time as cassette tapes or CDs, in turn also become obsolete since, if it does, we will have very big problems.
