Core Insights - Researchers at Ohio State University have demonstrated that edible fungi, such as shiitake mushrooms, can play a crucial role in the development of biological microchips, marking significant progress in "fungal computing" [1][2] Group 1: Fungal Properties and Functionality - Shiitake mushrooms can be trained to function as memristors, which are electronic devices capable of remembering the current that flows through them and adjusting their resistance accordingly, similar to synapses in the brain [1][2] - The root system of shiitake mushrooms forms a network of mycelium that serves as a primary conductive pathway, which can be connected to traditional electronic circuits [2] Group 2: Experimental Findings - The mycelium network retains its functionality even after dehydration and rehydration, indicating its potential for "cultivation, training, and preservation" in technological applications [2] - When connected to circuits and subjected to various waveforms and frequencies, the fungi demonstrated a memory function with an accuracy of up to 95% at 10Hz and 5V, although accuracy decreases at higher frequencies [2] Group 3: Environmental and Economic Advantages - Unlike traditional chips that require rare earth elements and expensive manufacturing processes, fungi provide an environmentally friendly and cost-effective alternative [3] - Fungal memristors consume very low energy, making them ideal for applications in wearable devices and sensors that require low power [3] - The presence of compounds like polysaccharides in shiitake cell walls grants them excellent radiation resistance, making them suitable for extreme environments such as space [3]
