Hello Friends

Researchers from the University of Washington and Microsoft have demonstrated the first fully automated system to store and retrieve data in manufactured DNA — a key step in moving the technology out of the research lab and into commercial data centers.

In a simple proof-of-concept test, the team successfully encoded the word “hello” in snippets of fabricated DNA and converted it back to digital data using a fully automated end-to-end system, which is described in a new paper published March 21 in Nature Scientific Reports.

In its first run, the $10,000 prototype converted "HELLO" into DNA. The device first encoded the bits (1's and 0's) into DNA sequences (A's, C's, T's, G's). It then synthesized the DNA and stored it as a liquid. Next, the stored DNA was read by a DNA sequencer. Finally, the decoding software translated the sequences back into bits. The 5-byte message took 21 hours to convert back and forth, but the researchers have already identified a way to reduce the time required by 10 to 12 hours. They've also suggested ways to reduce the cost by several thousand dollars.

In nucleotide form HELLO (01001000 01000101 01001100 01001100 01001111 in bits) yielded approximately 1 mg of DNA, and just 4 micrograms were retained for sequencing. As Technology Review notes, at that rate, all of the information stored in a warehouse-sized data center could fit into a few standard-size dice.
