BOSTON, June 3 (UPI) — Until now, synthetic biological systems have focused exclusively on either analog or digital computation. Researchers at MIT have devised a technique for creating cellular gene circuits capable of complex computation.

Analog computation, also called continuous computation, is the type of processing happening as the human eye adjusts to changing light conditions. Digital computation involves binary decision making, on or off processes.

The new synthetic cellular circuitry designed by MIT scientists performs like a comparator, receiving analog input signals and converting them into digital output signals.
