By encoding signal weights in promoter and RBS strengths, and using RNA-cleaving enzymes as nonlinear activation functions, genetic circuits can implement perceptron-style neural computation — graded, multi-input, noise-averaging. This week also covers fungal materials: from mycelium composites and leather alternatives to engineering fungi as autonomous building repair agents. The worked DNA design demonstrates how to prepare a codon-optimised insert for two different assembly strategies.Hugoen
