DNA data storage

Dithered illustration of DNA data storage

DNA data storage encodes computer files as sequences of synthetic DNA. It can last for millennia, and a short movie has already been stored in the genomes of living bacteria.

Humanity produces data faster than it can build places to keep it. DNA offers a way out: it holds information for millennia, stores it orders of magnitude more densely than current technology, and needs little energy to sit on a shelf. One coding scheme fits 215 petabytes into a single gram, a hundredfold gain on earlier pioneering methods. Writing the molecule is still costly. And the store need not be a test tube: a short movie has already been written into the genomes of living bacteria.

Pick a question to go deeper.

  1. Wow! signalThe Wow! signal is a 72-second radio burst an Ohio telescope caught in 1977 while searching for aliens. It never returned, and cold hydrogen clouds emit lookalikes a hundred times fainter.
  2. Solar sailA solar sail is a vast, thin sheet that lets sunlight push a spacecraft, with no propellant. In 2010 IKAROS proved it in flight, and its sail generated electricity too.
  3. AntimatterAntimatter is the counterpart of ordinary matter, and the two destroy each other on contact. In March 2026, 92 antiprotons were driven around CERN on a truck, and none were lost.
