An Ancient Alphabet for the Digital Age: Encoding digital information in DNA

🕔21:25, 8.May 2015

With mechanical failure, physical damage, and format obsolescence threatening devices from CDs to servers, we cannot count on the digital storage media that we use today to last forever. Robert Grass has discovered a more durable way to store digital information: by encoding it in silica-covered molecules of DNA.
