DNA, the strings of chemicals which define us, acts like a kind of read-only biological data storage device. Now, though, synthetic biologists have managed to turn DNA into a form or rewritable memory, just like that in our computers.
While it’s not the first rewritable biological storage system to be made—others have used proteins which bond to DNA to perform a similar function—it is the first time such an effect has been achieved in the DNA itself, and it could make synthetic digital cells a possibility.
