According to the University of Washington (UW) official website news, research scientists from the university and Microsoft in terms of DNA data storage goes a step further: they passed the 1's and 0 transcoding adenine, guanine, cytosine, and thymine this DNA nucleotide sequence of the four kinds of constitution, and the success of the pictures and videos stored in the DNA fragment, and a lossless data is read, the latest research will revolutionize computer or storage.
According to a report from the British Daily Mail recently, the amount of data of humanity "digital universe" is expected to reach 44 trillion GB in 2020. At that time it will exceed our storage capacity. In order to compensate for the lack of storage space, scientists are trying to store data information into DNA. UW associate professor of computer science and engineering Luis Sezi said, "Life creates the amazing molecule of DNA, which is capable of efficiently storing various data which are related with human genes and life systems. It is very compact and durable."
In the latest study, researchers converted 0 and 1 long sequence from the digital data of images and video into four basic components of DNA sequences. Subsequently, the digital data is divided into pieces and stored by being synthesized as a large number of artificial synthetic DNA molecules. Such molecules can be dehydrated and stored for a long time. Moreover, with the use of DNA sequencing technology, the researchers were able to "read" the data and convert it into original form, and a lossless image reading can be achieved. This study compresses digital data which can fill the entire Wal-Mart to the size of a lump of sugara.
Sezi said, "We used a series of molecular biology experiments to demonstrate the feasibility of our system design. We have succeeded in the data storage in the DNA and performance of random can read back to the original value."
The researchers explained that compared with the current digital storage technology, DNA molecules improves the tightness of data storage by hundreds of times. At the same time, the data storage devices we currently use such as flash memory, hard disk, magnetic disk and optical storage media would be damaged in a few years, but the new method can save the information for centuries.
However, the researchers said they are also facing a huge challenge, namely, to enhance the cost and efficiency of the new method so that it can be applied on a large scale.
