All data of the planet can be stored for millions of years in one teaspoon of DNA - VIDEO PDF Print E-mail

Even despite the fact that humanity seems to still find some way to erase myself from the face of the Earth, there is a chance that our spiritual heritage will survive. Server hard drives, flash drives and disks eventually destroyed, but a group of researchers from the Swiss Federal Institute of Technology found a way to encode data in the DNA - that will allow them to survive the millennium.
One gram of DNA can contain up to 455 exabytes of data, according to the magazine «New Scientist». For information: exabyte equals one billion gigabytes, and a thoUSAnd exabytes up zettabytes. According to estimates of cloud computing EMC, in 2011 the amount of data on our planet was about 1.8 zettabytes - and this means that we would need only about 4 grams of DNA (about a teaspoon) to save all mankind from the legacy of Plato to latest album, Beyonce.

DNA consists of four types of molecules that form a pair. To encode information in DNA, scientists have programmed these pairs in zeros and ones - a simple binary code, which is the basis of all digital data in our world. This is not a new approach - scientists from Harvard University have managed to encode the book into DNA in 2012, but to date the opposite extracting data from the molecule is the problem.

Previous tests showed the presence of gaps in the extracted data as DNA reacts to their environment and degrades at room temperature. Robert Grass, project leader of the Swiss Institute, has found a new way to store your data to treat it as a fossil. His team has entered into a DNA sample in a quartz envelope and kept him at a temperature of 60 degrees Celsius for a few weeks to test his strength.

After recovery of the sample, they were able to successfully assume the saved data, and, according to Grasse, if the DNA stored at temperatures below zero, the information from it can be considered even after millions of years.

To date, this process is very not cheap. The creation of the Swiss sample, which were coded 83 kilobytes of data took about $ 1,500, said Grass magazine «New Scientist».

However, with the development of new technologies the cost of DNA coding for sure will fall - and we can expect that the spiritual heritage of humanity will not be lost to us did not happen.
