Now its time to think something new; whats that? We have huge storage and storage devices but the data is growing more and more day by day. Recently Columbia University School of Engineering and Applied Science designed an algorithm for streaming video on cellphone can unlock DNA’s nearly full storage potential. DNA is an ideal storage medium because its ultra compact and can live hundreds of thousands of years if kept in a appropriate place.
Erlich and his colleague Dina Zielinski, an associate scientist at NYGC, chose six files to encode, or write, into DNA: a full computer operating system, an 1895 French film, “Arrival of a train at La Ciotat,” a $50 Amazon gift card, a computer virus, a Pioneer plaque and a 1948 study by information theorist Claude Shannon.
They compressed the files into a master file and then split the data into ones and zeros into strings. They then used an erasure-correcting algorithm called fountain codes they packaged strings into droplets and mapped ones and zeros in each droplet to four nucleotide bases in DNA.
To retrieve the files thy used modern sequencing technology to read DNA strands followed by the software to translate genetic code into binary. Finally the researchers show that they can pack 215 petabyte in 1 gram of DNA. This is highest density of storage found ever. Cost of doing this is still a barrier researchers spent 7000 dollar to synthesize the DNA they used to archive 2mb of data and another 2000 dollar to read it.
Microsoft is buying 10 million strands of DNA. According to Science Daily, they used DNA Fountain to generate 72,000 DNA strands or oligos that were sent to Twist Bioscience, the DNA synthesis firm that supplied Microsoft’s synthetic DNA.
