Data Storage in DNA Becomes a Reality
DNA is the building block of life, but in the future it may also be the standard repository for encyclopedias, music and other digital data. Scientists announced yesterday that they successfully converted 739 kilobytes of hard drive data in genetic code and then retrieved the content with 100 percent accuracy.

The researchers began with the computer files from some notable cultural highlights: an audio recording of MLK Jr.’s 1963 “I Have a Dream” speech, all 154 of Shakespeare’s sonnets, and, appropriately, a copy of Watson and Crick’s original research paper describing DNA’s double helix structure. On a hard drive, these files are stored as a series of zeros and ones. The researchers worked out a system to translate the binary code into one with four characters instead: A, C, G and T. They used this genetic code to synthesize actual strands of DNA with the content embedded in its very structure.

Legal! Será que usaram as quatro bases para codificar um sistema de correção de erros? Eu faria isso.

Massa, até onde eu sei o DNA é o sistema com melhor custo "espaço de informação/tamanho" de todos os HDs já feitos...

Eventualmente os PCs vão pegar vírus da gripe mesmo, e talvez vice-versa.

Muito legal mesmo. Mas como colocaram isso tudo em 739KB ?
