DNA as a data storage medium

Recommended Posts

Eldorado

"As a use case, the researchers 3D printed a rabbit out of plastic, which contains the instructions (about 100 kilobytes' worth of data) for printing the object. The researchers achieved this by adding tiny glass beads containing DNA to the plastic. "Just like real rabbits, our rabbit also carries its own blueprint," Grass says.

"And just like in biology, this new technological method retains the information over several generations -- a feature the scientists demonstrated by retrieving the printing instructions from a small part of the rabbit and using them to print a whole new one. They were able to repeat this process five times, essentially creating the "great-great-great-grandchild" of the original rabbit.

""All other known forms of storage have a fixed geometry: a hard drive has to look like a hard drive, a CD like a CD. You can't change the form without losing information," Erlich says. "DNA is currently the only data storage medium that can also exist as a liquid, which allows us to insert it into objects of any shape.""
