Researchers from Arizona State University have demonstrated that living cells can be induced to carry out complex computations in the manner of tiny robots or computers.
From this the scientists developed the first ribocomputing devices capable of four-input AND, six-input OR and a 12-input device able to carry out a complex combination of AND, OR and NOT logic known as disjunctive normal form expression.The great strength of the new method is with its ability to perform many operations at the same time. This capacity for parallel processing allows for faster and more sophisticated computation.The example, of meshing engineering and biology together, is part of an emerging field called synthetic biology, and it is one of the fastest growing areas of scientific research. In a sense, synthetic biology is a biology-based “toolkit”. According to the European research group ERBC the science deploys abstraction, standardization, and automated construction to change how we build biological systems and expand the range of possible products. One such example of what a highly accurate platform like this could do is with diagnosing viruses the Zika virus.The research has been published in the journalNature under the title “Complex cellular logic computation using ribocomputing devices.”
