Synthetic biology researchers have demonstrated a new method for digital information processing in living cells, analogous to the logic gates used in electric circuits. The circuits are the largest ever published to date in eurkaryotic cells and a key step in harnessing the potential of cells as living computers that can respond to disease, efficiently produce biofuels or develop plant-based chemicals.
Through billions of years of trial and error, evolution has arrived at a mode of information processing at the cellular level. In the microchips that run our computers, information processing capabilities reduce data to unambiguous 0s and 1s. In cells, it’s not that simple...
