A, T, G and C, they are adenine, guanine, thymine and cytosine, are zeros and units of living beings. Unlike the code stored in silicon, the data in the DNA will not decay for thousands of years. And DNA can save much more data - one gram of DNA can hold a billion terabytes of data. For comparison, popular hard drives have a capacity of 1 TB.
Scientists from ETH Zurich found out how to preserve one of the greatest works of mankind in a reliable environment of DNA: the epic Massive Attack album called Mezzanine, which was released 20 years ago. The masterpiece of the British trip-hop duo now lives in 5000 tiny glass beads, recorded in almost a million short strings of DNA.
To fit the data into DNA strings, they must first be translated from the binary code (0 and 1) into the four DNA bases (A, T, G, C). Then scientists need to synthesize DNA molecules (this is a very complex process) to ideally preserve this sequence. Then the sequences fit into these molecules. After dehydration and preservation under the right conditions, such molecules can live thousands of years.
Scientists do not save digital files for the first time in DNA; the work of Swiss scientists ranks second in the list of the largest files stored in DNA (the first place is occupied by Microsoft - its scientists were able to fit the video of the group OK Go! into DNA).
Unfortunately, while this process is very slow and very expensive. But if we encode all the masterpieces of humanity in DNA, we guarantee that future generations of cyber-humanoids will be able to enjoy great music and see the best vidosics.
