So they made some gates out of fungus?<p>> Thus, it would take about half an hour for a signal in the fungal computer to propagate 1 m. The low speed of signal propagation is not a critical disadvantage of potential fungal computers, because they never meant to compete with conventional silicon devices.<p>> Likely application domains of fungal devices could be large-scale networks of mycelium which collect and analyse information about environment of soil and, possibly, air and execute some decision-making procedures.<p>Pretty neat. There's a computer growing in the corner of my room.
