Sustainable memristors from shiitake mycelium for high-frequency bioelectronics

There's a theory that's been going around for a while that trees were using mycelium networks to communicate via electrical signals. Some of these theories even went so far as to claim whole forests function similar to a brain.

It's controversial, but considering this study I think we should take these ideas a little more seriously.

I thought this was fairly well proven at this point. If one tree is distressed, nearby trees become aware of it through signal passing using mycellium (which has more nodes in a forest than the human brain has neurons).

Fungi are deeply alien life. Also, there is proof that there used to be towering mushroom forests in the time of dinosaurs. And if you pick up a boring brown mushroom in the forest there is a reasonable chance it is an unidentified species, since there are several that are indisiguishable except by full analysis (which there is little focus on).

I've talked to biologists who think the idea is just new-age hippy nonsense.

It's not quite mainstream, Wikipedia goes over the current science fairly well: https://en.wikipedia.org/wiki/Mycorrhizal_network
