Making holes in DNA could help store data ktsimage/Getty
Some of the earliest computers used a punched card memory system – literally storing information on cards with holes punched out. Now researchers have found a way to apply the same concept to DNA.
DNA sequences have often been suggested as a form of data storage but many methods for doing this are painstaking or expensive – such as synthesising new DNA in the lab.
Instead, Olgica Milenkovic at the University of Illinois at Urbana-Champaign and her colleagues have made tiny cuts in existing strands of E. coli DNA, turning them into…
