Through their underground networks, fungi physically connect to plant roots, enabling the transfer of nutrients and chemical signals between trees: a system ecologists call the "Wood Wide Web."

Too long to read? Go for the highlights below. Researchers at Ohio State University built working memristors, circuit elements that remember past electrical states—using shiitake mushroom mycelium instead of conventional silicon or titanium dioxide The fungal memristor achieved 5,850 Hertz performance with 90% accuracy, switching signals approximately every 170 microseconds, approaching commercially available memristor speeds The technology offers potential for low-cost, scal
