One gram of DNA can store files of up to 2.2 million gigabits of data ranging from 468 thousand information or DVD, which can last up to more than six hundred years without rewriting.
Many molecular biologists were talking about DNA storage technology. And this technology is still foreign to us, but if we do not actually understand how the storage capacity of the human body.
Just imagine, since we are born continuously recording and learn everything. Where it all stored ? Decades of us live in the world still continues to record, and it requires considerable storage space, much larger than current technology.
Researchers from the UK have encodes DNA and translate the genetic material to reconstruct the written information, either sound or visual. In the past year, researchers and bioengineers Sriram Kosuri George Church of Harvard Medical School stated that they had kept a copy of one of the books stored in the DNA of the Church, with a density of about 700 terabits per gram, more than six times more dense than the data storage on the hard computer disk.
Current research led molecular biologists, including Nick Goldman and Ewan Birney of the European Bioinformatics Institute ( EBI ) in Hinxton - centered English, they study released in the journal Nature , stating that they have increased the DNA coding schemes to improve the storage density of up to 2 , 2 petabytes per gram, three times that of the previous findings.
The first team was first to translate written words or other data into the standard binary code (0s and 1s) and then convert them into trinary code. The next step rewrite the data into a string of DNA chemistry, such as Gs, Cs, and Ts. Storage density of one gram of DNA reached 2.2 million gigabits of data information, or about 468 thousand DVDs. The researchers also adds error correction scheme, several times doing the encoding of information, to ensure that it can be read back with 100 percent accuracy rate.
The explanation above is the same as is done in our bodies every second without stopping continued to write, and can be read back. In addition to demonstrating the ability of the storage of information in DNA, Goldman, Birney, and colleagues also reviewed viable when these technologies are used. While the Large Hadron Collider, have produced 15 petabytes of data each year , so the need for a large archive storage is growing rapidly.
Currently business institutions and institutional data archive store their data on magnetic tape, and to keep the data safe for decades require periodic rewriting (certainly no additional maintenance cost).
While DNA can be very stable for thousands of years if stored in a cool, dry place. The cost of DNA synthesis in accordance with writing code and decode can be resolved quickly, so allowing the data to be archived within 600 years or more.
But the cost of DNA synthesis became the most expensive parts up to 100 times, and probably would have declined by about 50 years. Cost is not a barrier, when data is written into the DNA of the users can not change or rewrite, not as data storage technologies available today.
Users can not access any particular piece of information, but must follow the order of writing that has been archived in the DNA. For example, the data writing 1,2,3,4 and 5, the user must read the order and could not jump over one of them.
From the explanation above, it could be someone who has the ability to 'read' your mind just by touching the hand, for example, actually he just read the records we've saved since birth.
