Bacterial Colonies Forming a Biological Logic Circuit MIT Built Logic Circuits From Bacteria, Using Living Cells as Transistors and Relays to Perform Digital Logic

MIT researchers have built working logic circuits using engineered bacteria, creating biological versions of components that electronics engineers would normally associate with transistors, relays and digital logic. The work uses Pantoea agglomerans, a bacterium that commonly grows on surfaces, including plants. The researchers modified the cells so they could function as two types of…
