Digital DNA storage developed, according to Nature News, ScienceNOW and Science DOI: 10.1126/science.1226355 16 August 2012 and ScienceDaily 17 August 2012. A team of scientists led by George Church of Harvard Medical School have developed a method of storing digital information on DNA. DNA information is encoded in a 4-letter system, A, T, C, and G, whilst digital information is ultimately stored as ones and zeros. The researchers developed a system where they encoded the zeros as As and Cs, and the ones as Gs and Ts. To encode data they divided it up into short sequences and encoded it onto a strand of DNA. Each block of data was replicated thousands of times to enable mistakes in coding to be identified and fixed by comparing it to the other copies. The strands of DNA were then embedded onto a glass chip. The strands also contain code that indicates where the information on it belongs in the original data file that it can be reassembled in the correct order. To retrieve the data the sequence of letters is analysed using DNA sequencing machinery, and the information from all the strands is combined and reconstructed using a computer. The research team tested their method by coding an entire genetics textbook, including the text, JPG images and a JavaScript program, onto 54,898 of these short strands, and then decoding and reconstructing the information to reproduce the original book. Even with multiple copies of each strand, the entire book was stored on less than a picogram (one trillionth of a gram) of DNA. The researchers commented: “DNA is among the most dense and stable information media known”.

Editorial Comment: Wake up guys! You have just admitted what we have been saying for ages. Your applaudably great success makes even more preposterous than it ever was, the theory that the DNA information stored and used by living cells got there by random chemical reactions through vast time spans. None of the information in your newly created DNA version of the printed textbook got there by chance random processes. Neither did it get into the original paper version by chance or any natural process. All methods of storing and reproducing information, whether as a printed book, a computer file or DNA on a chip, are the product of intelligent minds. They have all provably required creative design and clever engineering.
The more we discover about how information is stored, reproduced and applied in living things, the more we see the ultimate proof that life required a creative designer, so none of us has any excuse for ignoring our Creator God, who also gave us Legal Testaments full of information in a book that didn’t happen by accident either - His written Word.
