Shiitake-Pilze wurden genutzt, um als lebende Prozessoren zu fungieren, die Daten wie ein Halbleiterchip speichern und abrufen, jedoch nahezu ohne ökologischen Fußabdruck. Wissenschaftler zeigen, dass Pilze so trainiert werden können, dass sie wie Memristoren wirken – mikroskopische Komponenten zur Verarbeitung und Speicherung von Daten in Computerchips.

They may be better known for stir-fries than supercomputing, but **shiitake mushrooms have now been harnessed to function as living processors, storing and recalling data like a semiconductor chip but with almost no environmental footprint**.
**Scientists at Ohio State University have shown that fungi can be trained to act like memristors – microscopic components used to process and store data in computer chips**. The team found that shiitake-based devices demonstrated similar reproducible memory effects to semiconductor-based chips and could be used to create other types of low-cost, environmentally friendly, neural-inspired components.
After two months, the team discovered that when used as RAM, the mushroom memristor was able to switch between electrical states – and hold onto that information – at up to 5,850 signals per second, with around 90% accuracy. At low frequencies, it achieved up to 95% switching accuracy. Performance dropped as the frequency of voltages increased, but this could be remedied by connecting more fungi to the circuit.
While mushroom-based electronics aren’t entirely new, scientists have become increasingly interested in using fungi for computing and energy production. Mycelium forms a self-repairing, three-dimensional grid that transmits electrical impulses in response to stimuli, not unlike neurons in a brain. Unlike silicon, this kind of organic system is flexible, scalable and capable of growing into new configurations. And, of course, it’s much more eco-friendly than current synthetic models.
For those interested, here’s the link to the peer reviewed journal article:

Interestingly adds a bit more credence to the fact that trees utilize the mycelial network for communication.
I wonder what Dr. Paul Stamets has to say regarding this new discovery with shiitake mushrooms. He might be able to recommend different types of mushrooms that might accomplish the goal better than shiitake.
