Researchers Store Panda Pics in DNA, Hinting at a New Era of Data Storage
Two images were stored in and retrieved from DNA sequences, showcasing how the crucial genetic molecule can also can be used for data storage.
But a key difference between that older work and the recent team’s study is that the latter managed the storage feat without de novo DNA synthesis, which remains an uneconomical way of storing data in terms of time investment and cost. “In our scheme, the DNA sequences serve as addresses while the modification status of the letters now represent the data,” explained Long Qian, a researcher at Peking University and co-author of the paper, in an email to Gizmodo. DNA as a venue for data storage is a tantalizing prospect; it’s amazing that such a small molecule could contain so much information—about ourselves, of course, but then could have a double life as a repository for contact information, photo libraries, full highlights of the 1974 FA Cup final—you name it.
