Floppy disks, jump drives, DNA? Scientists have developed a way to encode music and text files into DNA, the molecules that normally hold the instructions for life. <\/p>\n
The new method, described today (Jan. 23) in the journal Nature, is extremely expensive right now, but eventually it could be used to store digital files without electricity for thousands of years. And since DNA is so compact, vast amounts of data could be stored in one test tube, said study author Nick Goldman, a geneticist at the European Bioinformatics Institute in the U.K. <\/p>\n
\"I've gone from being a skeptic to a believer,\" said David Haussler, a geneticist and computer scientist at the University of California, Santa Cruz, who was not involved in the study. <\/p>\n
And because DNA is the script of life, crucial in medicine, agriculture and other endeavors, human beings will always be pushing for ways to improve the reading and writing of DNA, Haussler told LiveScience. [Genetics by the Numbers: 10 Tantalizing Tales] <\/p>\n
The team has even used the method to encode Shakespeare's sonnets. <\/p>\n
Data deluge <\/p>\n
From floppy disks to CDs to magnetic tapes, the technologies to store, read and write digital data become obsolete rapidly. Digital archives take a lot of space, and the files themselves, even archival magnetic tapes, need to be freshened up or rewritten every few years to prevent degradation. <\/p>\n
Goldman and colleague Ewan Birney, also of European Bioinformatics Institute, were discussing this problem over beers one day when they realized that DNA might actually be feasible to store vast amounts of data. <\/p>\n
As the discovery of intact woolly mammoth DNA demonstrates, the molecule can last for tens of thousands of years as long as it's stored in a cool, dark place, they said. It doesn't require electricity to maintain, like hard drives do, can include built-in error checking, and it's incredibly compact, Goldman told LiveScience. (Earlier this year, another team demonstrated the feasibility of DNA storage, but stored a tiny amount of data and didn't include error checking.) <\/p>\n
