Using Fungi to Grow Biodegradable Computer Memory
Deep under forests, fungi build invisible cities. Thin white threads called mycelium stretch for miles, linking trees and plants. These networks share water, food, and danger signals. A tree attacked by bugs sends warnings through the threads. Nearby plants get ready to fight back. This system works without a central brain. Each part senses and reacts on its own.
Via Interesting Engineering
Scientists study these natural webs to copy them. The signals in mycelium are tiny electrical pulses. They travel like data in wires. Researchers saw a chance to use this for computers. Instead of metal paths, living threads could carry information. This idea sparked fungal computing, a way to make machines from mushrooms.
Via Phys
Fungi also handle stress well. They live through floods, freezes, and dry spells. Some break down wood or oil spills. This toughness hints that they can take electrical loads without breaking. Early tests showed mycelium changes when zapped with voltage. The threads swell or shrink, altering how current flows. This shift stores a bit of data, like a 0 or 1 in binary code.

This created memory loops. Graphs of the data showed smooth curves, proof of reliable switching. Linking two mats boosted performance. Signals passed between them, mimicking brain synapses. The accuracy hit ninety-five percent over thousands of cycles. The setup used less than a watt of power, far below silicon chips.

Temperature affects speed. Warmer mats react faster but tire sooner. Room temperature gave the best balance. Humidity mattered too. Too dry, and signals stalled. A light spray fixed it in seconds. This hydration trick makes storage easy. Dry a mat for shipping, then wake it on arrival.

Instead of metal paths, living threads could carry information. This idea sparked fungal computing, a way to make machines from mushrooms.
Why Mushrooms Caught Scientists' Attention
Mushrooms grow fast and cheaply. A handful of spores on damp grain becomes a thick mat in days. No need for clean rooms or billion-dollar plants. Shiitake, oyster, and button types work best. Their mycelium forms dense layers perfect for testing.

Step-by-Step Look at Ohio State's Experiments
The Ohio State team started small. They filled plastic trays with wheat germ and hay. Mushroom spores sprinkled on top grew into white fuzz. After ten days, the mats were thick enough to handle. Sun-drying locked the shape but kept the inner paths intact. A quick mist of water revived conductivity. They poked thin wires into the dried mats. One wire sent pulses; another read the response.

Inside the Fungal Memristor
A memristor remembers resistance even when power is off. Silicon versions exist but need rare metals. Fungal ones form naturally. The mycelium's hyphae, tiny tubes, fill with ions during pulses. These charged particles block or open paths. The effect lasts until reversed by the opposite voltage.

Comparing Fungal Chips to Traditional Semiconductors
Silicon chips pack billions of transistors in a square inch. Fungal mats cover a palm but hold less data. Speed lags, kilohertz versus gigahertz. Yet for many tasks, raw speed isn't key. Sensors in farms or homes process slow changes like soil moisture. Fungal chips excel there with tiny power draws.

Real-World Durability Tests on Shiitake
The team exposed mats to extremes. UV lamps mimicked sunlight for weeks. Silicon controls yellowed and failed. Fungal samples darkened but kept switching. Lentinan, a sugar in shiitake, absorbed the energy. Melanin pigments added extra armor. Radiation trials used cobalt sources. Doses that kill electronics leave fungi functional.

Scaling Up from Lab to Factory
Small trays prove the concept. Larger growth needs control. Steel tanks with nutrient mist can yield meter-wide sheets. Automated arms harvest and dry them. Templates press circuits into wet mats before drying. The result: ready-to-wire boards.
