Unique & Funny Magazine: Microsoft sets DNA strand storage record

All digital storage devices we use – flash drives, hard disks, magnetic and optical media, degrade after a few years .

But Microsoft and the University of Washington have stored 200 megabytes of data into something that will preserve the information for centuries -. DNA

researchers have successfully transferred the Universal Declaration of Human Rights in over 100 languages and a video of the band OK Go to “This Too Shall Pass’ on one strand molecular.

Microsoft and University of Washington have stored 200 megabytes of data into something that will preserve information for centuries – DNA. The duo announced transferred the Universal Declaration of Human Rights in more than 100 languages, the top 100 classic books and high definition video clip of the band OK Go to “This Too Shall Pass’ on a molecular strand

HOW DID THE pLACE oF DIGITAL dATA iN DNA?

researchers started with a method that converts long strings of ones and zeros in the digital data in the four building blocks of DNA sequences – adenine, guanine, cytosine, thymine.

The digital data were then cut into pieces and stored by the synthesis of a massive number of tiny DNA molecules, which can be dried and stored for a long time.

to retrieve the stored data, the encoded team the equivalent of postcodes and street addresses in the DNA sequences, allowing them to easily find what that they need.

and using DNA sequencing techniques, researchers can “read” the data and transform it back in its original form using street addresses to reorganize data.

[19459003numérique] They successfully encoded and retrieved data from images and videos.

‘We wanted to store something creative and in a modern format, Luis Ceze, Washington University associate professor of computer science and engineering and of the University of homing on the project, said in a Q & a with the media department of the University of Washington.

HD video was a natural choice for the format. And OK Go – be such a tape creation – was a perfect fit.

“Furthermore, there is an interesting connection between Rube Goldberg machines and molecular biology.

In addition to the government document and the video for OK Go is housed in the strand, also searches stored top 100 books from Project Gutenberg and the initial database of the trust of cultures – among other things.

“This experience has led to several important advances that have improved our ability to handle more complex pools of synthetic DNA, said Ceze.

‘This allowed us to better understand which types of errors arise and how to deal with them.

experts say that the “digital universe” could hit 44 billion gigabytes by 2020, exceeding our storage capacity.

and to compensate for the lack of space, Microsoft and the University of Washington have worked to reduce the massive amounts of digital data that could fill a Walmart supercenter the size of a cube Sugar.

The team started with a method that converts long strings of ones and zeros in the digital data in the four building blocks of DNA sequences -. Adenine, guanine, cytosine and thymine

Furthermore the government document and the video for OK Go (photo) being housed in the strand, research stored as the best 100 books from project Gutenberg and the Crop Trust seed database – among other things. Using DNA does not open a new storage area, but it is extremely durable

The digital data were then cut into pieces and stored by the synthesis of a massive number of tiny DNA molecules, which can be dehydrated and stored for a long period.

to retrieve the stored data, the encoded team the equivalent of postcodes and street addresses in the DNA sequences, allowing them to easily find what that they need.

and using DNA sequencing techniques, researchers can “read” the data and transform it back in its original form using street addresses to reorganize data.

SCIENTISTS FIND WAY TO STORE DATA INSIDE dE FOSSIL SYNTHETIC

The researchers say that the encapsulation the silica is similar to that of fossil bones.

long-term DNA stability can be estimated by comparison with other DNA storage facilities, such as Svalbard Global Seed Vault in Norway, where the material genetics is stored at minus 18 degrees Celsius and can survive for more than a million years.

to demonstrate the technology, the researchers encoded in DNA “methods of mechanical theorems” written by the ancient Greek scholar Archimedes at least two thousand years ago

We decide how a letter is translated into a sequence of say nucleotides -. so that the building blocks of DNA. And so we then generate a huge file, instead of letters, spaces and numbers, it is just a sequence of A, C, T and G ‘, said Dr. Robert Grass, senior researcher at the ETH Zurich .

This file we send to a company and the company that synthesizes DNA in our file, we sent them. They then synthesize DNA sequences with exactly the sequence of nucleotides that we preset.

They then simulated the degradation of DNA over a long period of time by storing them at a temperature between 60 and 70 degrees Celsius for up to one month, the degradation reproducing chemical that takes place hundreds of years in a few weeks.

glass shells have proven to be particularly robust and, thanks to the use of a fluoride solution, the DNA could be easily separated from the glass so that information can be read.

successfully decode the information encoded in the DNA required FAIL built in safety mechanism.

new algorithms designed by Reinhard Heckel of Communication Technology Laboratory at ETH Zurich adds additional layers of information on actual data so that it was always precise and error, even if one of the pieces of data has been lost or misplaced.

“When one wants to read the data, the DNA is resuspended and read by a DNA sequencer, which determines that A, C, G, T letters include molecules. From there, our algorithms retrieve the original digital data, said Ceze

“We have also developed a method for random access”, meaning that you read selectively only the data you want and not the whole. We do this by borrowing from nature again and using DNA amplification – using polymerase chain reactions in particular – only amplify the desired data

L using these tiny molecular wires will not open. a new storage area for our photos, e-books and music, but the DNA, it is extremely durable.

This material is able to last very long if kept in good conditions (the woolly mammoth DNA was recovered several thousand years after they were extinguished , for example). – And always will be, the researchers believe

In order to retrieve the stored data, the encoded team the equivalent of zip codes and addresses Street in the DNA sequences. The DNA molecules are capable of storing information of millions of times denser than existing technologies for digital storage, the researchers explained

the digital data (such as the universal Declaration of human rights) was cut into pieces and stored by the synthesis of a massive number of DNA molecules, which can be dried and stored for a long time. To retrieve it, they encoded the equivalent of zip codes and addresses of the street in the DNA sequences

“As long as DNA-based life on the planet, we will be interested in reading, “said Karin Strauss, principal investigator of Microsoft on the project.

‘So it is eternally relevant.

This is not the first time that the duo media stored on DNA, in April, they announced the successful transportation of three image files.

These pictures were cut into pieces and store in synthesizing a massive number so tiny DNA molecules.

The team encoded digital data from image files (in April) in a nucleotide sequence of synthetic DNA fragments and reverse the process to recover – with no data loss. The digital data and then cut into pieces and stored by the synthesis of a massive number of tiny DNA molecules

Although the idea has been tried before, digital data now the researchers coded from image files in a nucleotide sequence of synthetic DNA fragments and reverse the process to recover. – With the loss of zero data

“We demonstrate the feasibility of our system design with a series of wet lab experiments, in which we have stored successfully DNA data and perform a random access to read the return values selected, “reads the paper.

‘We are still evaluating our design using simulations to understand the error correction characteristics of different coding schemes, evaluate their overhead and make projections on future feasibility based on technology trends. “

the University of Washington and Microsoft researchers worked together to reduce the massive amount of digital data that could fill a Walmart supercenter, the size of a sugar cube. The group faces a challenge – which makes this more cost effective and efficient way so that it can be done on a large scale

DNA molecules are capable of storing the information of several million times more densely than existing technologies for digital storage, the researchers explained.

However, the group faces a challenge and makes this more cost effective and efficient method so it can be done on a large scale.

‘this multidisciplinary approach is what makes this exciting project, “said Karin Strauss, a researcher at Microsoft and affiliated UW associate professor of computer science and engineering.

‘We draw from a diverse set of disciplines to push the boundaries of what can be done with DNA.

and, consequently, the creation of a storage system with unprecedented density and durability.
