Aa encoding

Scientists say that the book could soon be cheaper to store information in DNA during installation digital camera

first time scientists have used DNA to encode the contents of a book. A 53 000 words and include 11 images and a computer program, which is the largest amount of data stored, even using the genetic material artificially.

The researchers say that the cost of DNA encoding falls so rapidly that within five to 10 years might be cheaper to store information using this method than conventional digital devices.

deoxyribonucleic acid or DNA - the chemical that stores genetic instructions in almost all known organisms - has an impressive capacity data. Gram can store up to 455bn gigabytes:. The content of over 100 billion DVDs, which makes the ultimate compact storage media

A strong team of three led by Professor George Church, Harvard Medical School has shown that the technology to store data in DNA, while slow, it is more convenient. They report in the journal Science that 5.27 megabits of data collection that store more than 600 times larger than the largest data set previously encoded this way.

write data into the DNA took several days. "This is something that today for file storage," said co-author Dr. Sriram Kosuri Wyss Institute at Harvard University, "but getting better all the time."

DNA has many advantages traditional digital storage media. You can easily copy and is often still legible after thousands of years in ideal conditions. Unlike evolving electronic formats such as tapes and DVDs, the fundamental skills needed to read and write information in DNA are as old as life on Earth.

The researchers, who have filed a provisional patent covering the concept, used off the shelf components to demonstrate his technique.

To maximize the reliability of his method, and reduce costs, avoid the need for very long sequences of code - which is much more expensive to create a large number of short pieces of DNA . The data is divided into fragments that could be written very reliable, and was accompanied by a list of Address Book where to find each section of code.

The team has developed a system in which a inkjet printer includes short DNA fragments artificially synthesized on a glass slide. Each DNA fragment also contains a numeric code indicating the address of the location in the original file.

fragments on the chip can then be "read" using standard techniques of the type used to decipher the ancient DNA sequence in the archaeological material. Then, a computer can reassemble the original file in the correct order using the address codes.

The book - a draft HTML of a volume co-written by the team leader -. It was written for DNA with embedded images to demonstrate the versatility of storage media

DNA dense storage system, as it is in three dimensions. Other storage media technologies, including drivers, such as the position of the individual atoms on a surface substantially reduced to two dimensions.
