(Unbelievable what science is exploring for future memory.)
While the role of DNA as a biological memory is well established exploring its potential as a data memory is relatively new. DNA data memory has not quite yet reached the stage where a blob of DNA can have some wires attached to it to write and read its data content, good progress has been made.
The their latest work, published in Science magazine, Yaniv Erlich and Dina Zielinski from Columbia University and the New York Genome Center, mixed some clever biochemistry with some leading edge communications data encoding techniques and added a dash of processing power. The result, under the heading of “DNA Fountain,” is a demonstration of the ability to use DNA to store a complete operating system of 1.4 MBytes, a movie and other files for a total of greater than 2 Mbytes.
This is now possible because at the same time they have provided a new level of efficiency and reliability for the technique.
