Scientists Develop Functional Computer Memory Using Shiitake Mushrooms
Scientists are experimenting with using parts of mushrooms, called shiitake, to create tiny computer memory pieces, like a brain's memory.
These mushroom parts, called mycelium, can actually 'remember' electrical signals, similar to how brain cells do.
This could lead to cheaper and more energy-efficient computer parts compared to the ones made from silicon.
While these mushroom memory pieces aren't as fast as today's computer parts, they work and use less power.
The researchers found that using more mushroom parts helped them work better, even when more electricity was applied.
This is an early step towards building computers that work more like our brains, which could save a lot of energy in the future.
Scientists have developed functional computer memory devices, called memristors, using shiitake mushroom mycelium.
These 'mushristors' leverage the neuron-like properties of mycelium to 'remember' past electrical states.
This innovation offers a potential low-cost alternative to traditional memory hardware made from materials like silicon.
The fungal memristors achieved a switching speed of 5,850 Hertz with around 90% accuracy, though slower than commercial alternatives.
The research highlights the potential for fungi in developing energy-efficient, brain-like computing hardware.
