City of York - England - Glide Gear DNA 5050
Me and a friend having a first go at using the glide gear equipment. We just walked around York city center. Please don #39;t judge to harshly.. Was lots of fun and hope to make more video #39;s soon. Still working out how to balance the glide gear as it sways abit as you can see in the video. The equipment used was Canon 5D mark iii Canon 17-40mm Glide Gear DNA 50/50

It can store the information from a million CDs in a space no bigger than your little finger, and could keep it safe for centuries.

Is this some new electronic gadget? Nope. It's DNA.

The genetic material has long held all the information needed to make plants and animals, and now some scientists are saying it could help handle the growing storage needs of today's information society.

Researchers reported Wednesday that they had stored all 154 Shakespeare sonnets, a photo, a scientific paper, and a 26-second sound clip from Martin Luther King Jr.'s "I Have a Dream" speech. That all fit in a barely visible bit of DNA in a test tube.

The process involved converting the ones and zeroes of digital information into the four-letter alphabet of DNA code. That code was used to create strands of synthetic DNA. Then machines "read" the DNA molecules and recovered the encoded information. That reading process took two weeks, but technological advances are driving that time down, said Ewan Birney of the European Bioinformatics Institute in Hinxton, England. He's an author of a report published online by the journal Nature.

DNA could be useful for keeping huge amounts of information that must be kept for a long time but not retrieved very often, the researchers said. Storing the DNA would be relatively simple, they said: Just put it in a cold, dry and dark place and leave it alone.

The technology might work in the near term for large archives that have to be kept safe for centuries, like national historical records or huge library holdings, said study co-author Nick Goldman of the institute. Maybe in a decade it could become feasible for consumers to store information they want to have around in 50 years, like wedding photos or videos for future grandchildren, Goldman said in an email.

The researchers said they have no intention of putting storage DNA into a living thing, and that it couldn't accidentally become part of the genetic machinery of a living thing because of its coding scheme.

Sriram Kosuri, a Harvard researcher who co-authored a similar report last September, said both papers show advantages of DNA for long-term storage. But because of its technical limitations, "it's not going to replace your hard drive," he said.

Kosuri's co-author, Harvard DNA expert George Church, said the technology could let a person store all of Wikipedia on a fingertip, and all the world's information now stored on disk drives could fit in the palm of the hand.

DNA could store all the world's digital data, says study

Paleontologists routinely resurrect and sequence DNA from woolly mammoths and other long-extinct species. Future paleontologists, or librarians, may do much the same to pull up Shakespeares sonnets, listen to Martin Luther King Jr.s I have a dream speech, or view photos. Researchers in the United Kingdom report today that theyve encoded these works and others in DNA and later sequenced the genetic material to reconstruct the written, audio, and visual information.

The new work isnt the first example of large-scale storage of digital information in DNA. Last year, researchers led by bioengineers Sriram Kosuri and George Church of Harvard Medical School reported that they stored a copy of one of Churchs books in DNA, among other things, at a density of about 700 terabits per gram, more than six orders of magnitude more dense than conventional data storage on a computer hard disk. Now, researchers led by molecular biologists Nick Goldman and Ewan Birney of the European Bioinformatics Institute (EBI) in Hinxton, U.K., report online today in Nature that theyve improved the DNA encoding scheme to raise that storage density to a staggering 2.2 petabytes per gram, three times the previous effort.

To do so, the team first translated written words or other data into a standard binary code of 0s and 1s, and then converted this to a trinary code of 0s, 1s, and 2sa step needed to help prevent the introduction of errors. The researchers then rewrote that data as strings of DNAs chemical bases: As, Gs, Cs, and Ts. At the storage density achieved, a single gram of DNA would hold 2.2 million gigabits of information, or about what you can store in 468,000 DVDs. Whats more, the researchers also added an error correction scheme, encoding the information multiple times, among other tricks, to ensure that it could be read back with 100% accuracy.

Beyond demonstrating DNAs superlative information storage abilities, Goldman, Birney, and their colleagues also asked when such a technology might be worth implementing. Institutions such as the Large Hadron Collider, a particle accelerator in Geneva, Switzerland, produce on the order of 15 petabytes of data each year. So the need for vast archival storage is growing rapidly. Now, such institutions commonly archive data by storing it on magnetic tape. Keeping that data safe over many decades requires rewriting it at regular intervals, adding to the cost of preservation. DNA, on the other hand, can be stable for thousands of years if kept in a cool, dry place. Goldman also notes that the costs of synthesizing DNA, which corresponds to writing the code, as well as sequencing, or reading out the code, are dropping fast. According to the EBI researchers, at current rates, DNA data storage is now cost-effective for only data that need to be archived for 600 years or more. But if the costs of DNA synthesiscurrently the most expensive part of the enterprisedrop 100-fold, that break-even number would drop to about 50 years.

Harvards Kosuri calls the latest study good work. But he says that cost wont be the hitch. For starters, he notes, once you write a batch of data in DNA, you cant change it or rewrite over it, as is often done with other data storage technologies. And you cant access any particular piece of information, but rather must sequence large swaths of DNA to find what youve archived.

So even though DNAs data storage densities are off the charts, it may still be worth putting those family photos on a DVD for now.
