Episode 91: Entangled Life and the wood wide web

Episode 91: Entangled Life and the wood wide web

Author: Tom Chivers and Stuart Ritchie November 18, 2025 Duration: 1:01:28

Everyone has read Entangled Life, the wonderfully-written book about fungi that took the world by storm about 5 years ago. Among many other things, it popularised the “wood wide web”—the idea that trees can communicate with one another through networks of fungi at their roots.

But is the wood wide web real? It turns out scientists have some major questions. We air them on this episode.

And just to be completely clear, there are no personal vendettas here! Everyone recording this podcast is 100% free of “beefs” of all kinds. Even the co-host who was beaten in a book contest by the aforementioned mushroom book.

The Science Fictions podcast is brought to you by Works in Progress magazine. Their most recent article is about the wonderful invention (and history) of the dishwasher, one of several incredible labour-saving devices that have made so many lives just a bit less dull. Read this, and so many more stories about human progress, at worksinprogress.co.
