Scientists successfully store computer files in DNA2017-03-06 14:43 by Daniela
Researchers from Columbia University, working with the New York Genome Center, have successfully packed a whole bunch of data onto DNA molecules and then reliably retrieved it in perfect condition. The scientists Yaniv Erlich and Dina Zielinski dramatically increased the capacity of DNA storage while using a new technology, called "DNA Fountain."
This is the highest-density large-scale data storage scheme ever invented. The system is capable of storing 215 petabytes (215 million gigabytes) in a single gram of DNA. This means that we could fit all the data in the world in the back of a car.
With "DNA Fountain" digital data is converted from binary into chunks of digits that are then translated into DNA base pairs. Each portion of the DNA data is also given an identifier so that it can be easily placed back into the correct order when converting it back into a digital file.
"DNA won't degrade over time like cassette tapes and CDs, and it won't become obsolete," says Yaniv Erlich, a computer scientist at Columbia University.
