Bacterial colonies act as transistors/ molecular relays to construct living "circuit boards" performing multi-input logic calculations

https://www.eurekalert.org/news-releases/1140510 "prints up to 24 Pantoea agglomerans colonies on agar plates to create cell-based switches controlling production/ spatial flow of signaling molecules (instead of electric currents) to downstream components... combines 2 bacterial transistors with 3 relay strains... also performs demultiplexing... embeds autonomous computational control into living systems, such as coating agricultural crops to monitor pests and environmental conditions... demonstrated mathematical addition over eight-hour biological timescales" Related: Slime mold-inspired computing https://www.eurekalert.org/news-releases/1141335 MIT engineers connect bacteria to create living transistors https://news.mit.edu/2026/mit-engineers-connect-bacteria-to-create-living-transistors-0817
