Early research has allowed DNA to be made into circuits or small factories, but has never seen DNA as a storage medium. Researchers at Harvard University have turned this dream into reality.

The team, led by George Chezzi (George Church), Serillam Kusuri (Sriram Kosuri) and Highland (Yuan Gao, transliteration), can store 96 bits of data in the DNA chain. The specific method is to give the binary value to adenine, guanine, cytosine and thymus, then the gene sequence is synthesized by microfluidic chip, which matches the position of the sequence with the related data set.

The technology does not seem to be great on the surface, but using microscopic materials to store macroscopic data can achieve unexpected results: 1 cubic millimeters can store 704TB of data, equivalent to hundreds of hard disk capacity. While the results are encouraging, the process is slow, so it is not possible to store time-sensitive data. In addition, cells in the DNA may damage the DNA chain, so they are not suitable for data transmission.

But in any case, such a large data density is expected to back up the knowledge of mankind. But most people's ideas may be more practical-when can you buy an organic hard drive at affordable prices?
