Summary: A team of Harvard researchers have managed to encode a book onto DNA, paving the way for wider use of the technology as a storage medium.<\/p>\n
Harvard researchers have succeeded in storing an entire book on DNA and reading the information back, paving the way for the use of the building block of life as a high-density storage medium. <\/p>\n
The research was published in Science on Friday. The researchers used a combination of commercial tools for DNA synthesis and new methods of DNA sequencing to store a copy of lead researcher George Church's forthcoming book Regenesis: How Synthetic Biology Will Reinvent Nature and Ourselves in DNA onto DNA. <\/p>\n
\"The density is remarkably high,\" Church says in a video explaining the research. \"We can store on the order of almost a zettabyte [of data] in a gram of DNA.\" <\/p>\n
This method can store data at densities many orders of magnitude greater than current non-biological techniques. By comparison, Church's DNA method can store around 125TB of information in one cubic millimetre of DNA, while prototype heat-assisted magnetic recording technology from Seagate can store 125GB of information per square inch. <\/p>\n
The team stored the information by encoding the book as binary code and using the base pairs of DNA for binary characters. A and C stood for zero, while T and G for one. The book was split into 96-bit data blocks which each had a 19-bit address to allow them to be reassembled. Each block was written as its unique DNA sequence, which the team sequenced 54,898 of to create the book. <\/p>\n
In the future, Church imagines a world full of \"very inexpensive [DNA-based] biological cameras\" that record video footage for later analysis by big data technologies. However, the cost of the sequencing and encoding technology would need to dramatically come down for such a scenario to be possible. <\/p>\n
The funding for the research came from the US office of Naval Research, Agilent Technologies and the Wyss Institute. <\/p>\n<\/p>\n
