Humanity is currently producing data at exponential rates and we need devices to store it all.
Scientists are solving this modern problem with nature’s age-old solution for information-storage – DNA.
Using this amazing technique the team believe we could compress all the world’s data into a single room.
Now researchers have been able to pack 215 petabytes of data on a single gram of DNA – 100 times more than previous efforts.
HOW DOES IT WORK?
The researchers began with a method that converts the long strings of ones and zeros in digital data into the four basic blocks of DNA sequences – adenine, guanine, cytosine and thymine.
The digital data was then chopped into pieces and stored by synthesizing a massive number of tiny DNA molecules, which can be dehydrated and preserved for a long time.
In all they generated a digital list of 72,000 DNA strands, each 200 bases long.
