Living Computers with Shiitake Mushrooms 🍄💻
How Shiitake mushrooms became biological memristors and are shaping the future of sustainable biological computers
Introduction: Shiitake Mushrooms and the World of Biological Computers
In recent decades, computers have moved towards higher speed, density, and lower consumption, but heavy reliance on silicon and chemicals has created environmental and cost limitations. Researchers at Ohio State University, inspired by nature, have shown that Shiitake mushrooms 🍄 can be transformed into biological memristors. These memristors can store information, change resistance, and perform functions similar to traditional hardware. This transformation has brought the concept of "living computers" into the real world.
The idea of using living organisms in computing is important not only for reducing costs and energy consumption but also for shaping organic and sustainable hardware. This approach can pave the way for the development of green IoT and neuromorphic computing.
