You know, one gram of DNA can store files up to 2.2 million gigabits of data information or about 468 thousand DVD, which can last up to more than six hundred years without a rewrite.

A new technology that might replace today's hard disk storage technology. During this storage technologies such as flash drives that we use everyday, has a weight of more than one gram. While one gram of human DNA that exist in the body, can store data of millions of times more, impressive is not it?
_Many molecular biology scientists are talking about DNA storage technology. And indeed this technology is still foreign to us, but it really is not if we understand how the storage capacity of the human body. Just imagine, since we were born continued recording and learned everything. Where is all of it stored? Decades of living in the world we still continued to record, and it requires considerable storage space, much larger than the current technology.

Researchers from Britain and translate DNA encodes genetic material to reconstruct the information in writing, either sound or visual. In the past year, researchers bioengineers Sriram Kosuri and George Church of Harvard Medical School said 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 storage of data on a hard computer disk.

Current research led by experts in molecular biology, including Nick Goldman and Ewan Birney of the European Bioinformatics Institute (EBI) in Hinxton-centered English, they study released in the journal Nature, said that they have increased the DNA coding scheme to improve the storage density of up to 2 , 2 petabytes per gram, three times the previous findings.

The first team the first time 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 string into DNA chemistry, such as Gs, Cs and Ts. Storage density of one gram of DNA to 2.2 million gigabits of data information, or about 468 thousand DVD. The researchers also added error correction schemes, several times doing the encoding of information, to ensure that it can be read back with 100 percent accuracy rate.

Explanation on the same as it did in our bodies, every second to keep writing without stopping, and can be read back. In addition to demonstrating the ability of the storage of information in DNA, Goldman, Birney, and colleagues also reviewed when the technology is fit for use. While the Large Hadron Collider, has been generating 15 petabytes of data per year, so the need for archival storage is now growing rapidly. Today business organizations and institutions data archive store their data on magnetic tape, and to keep data secure for decades require periodic rewriting (of course there are additional maintenance costs).

While DNA can be very stable up to thousands of years if stored in a cool, dry place. Cost of DNA synthesis in accordance with writing code and reading the code can be resolved quickly, it's possible to archive the data in time 600 years or more.

But the cost of DNA synthesis became the most expensive up to 100-fold, and may experience a decrease of approximately 50 years. Cost is not a barrier, when data is written into the DNA so the user can not change or rewrite, unlike the data storage technology available today. And users can not access any particular piece of information, but must follow the order of the writing that has been archived in the DNA. As an example of writing data 1,2,3,4 and 5, the user should read the order and could not jump over one of them.

From this research it is clear that I did not ever believe the term dementia, amnesia, or the like that make it hard to remember. Because the data we stored in human DNA can not be removed, people just need to find a storage room, where the record is stored, still lies within us. That's why there are people who can read minds just by touching the skin, in fact he's just reading the record we've saved since birth.
