Nature has indisputably invented the best solution for storing a massive amount of data: DNA. This understanding has inspired the use of DNA for the storage of digital data, converting binary (0 or 1) numbers into one of the four different DNA “letters” (A, T, C, or G).
But how does one find a specific datum in the library of information stored as DNA? And how can calculations with DNA-encoded data be performed directly, without first converting them back into electronic data? These are the questions that teams from the LIMMS (CNRS / University of Tokyo) and Gulliver (CNRS / ESPCI Paris-PSL) research laboratories have sought to answer. They are testing a new approach using enzymes and applying the solutions of artificial neurons and neural networks for direct operations on DNA data.
