We’ve spent this season tracing how fungi, and especially mycelium, can shake up industries and remediate the harm caused by climate change. We’ve talked about foraging, growing, healing and commercializing mycelium. But there’s one frontier we saved for this episode, the last of this season. It’s one that, here at Healthy Materials Lab, we’re honestly most excited about: affordable housing. We speak with Chris Maurer and the team at BioHab, who are building housing with mycelium.  This...

Mycelium based materials have a wealth of potential applications. But how does a new material get out of the experimental phase and into mass production? That transition is often where material development can stall. Luckily, that isn’t happening with mycelium. In this episode, we speak with Gavin McIntyre, who is the co-founder and Chief Commercial Officer at Ecovative. Ecovative is a revolutionary company at the forefront of the mycelium industry. He leads us through the journey Ecovative...

Did you know that Mycelial networks can break down dead plant or animal matter and they can connect with the roots of living plants to share nutrients between them? Whether that was news or not, mycelial networks are much more complicated than you might imagine.  To get down in the dirt with them, we spoke with Maya Elson. Maya works with CoRenewal, a nonprofit dedicated to providing education and research in ecosystem restoration, where she leads projects around post-fire bioremediation and...

The power of fungi has been neglected by academic institutions and marginalized in the larger society. By the 1960s the American imagination had linked fungi to magic mushrooms, the counterculture movement, and Nixon’s war on drugs. That lingering association has meant that American mycophiles have gathered in community at the margins. We wanted to dig into those margins with William Padilla Brown, a citizen scientist who’s been thriving at them. William is the founder of Mycosymbiotics, and...

In this episode we go on a journey led by revered mycologist John Michelotti into the forests of the Catskill mountains to learn the basics about what makes mushrooms so special. Can fungi change the way we approach our ecosystem? Can they give us healthier food systems, healthier bodies, healthier materials, and healthier housing? That’s what we want to explore this season, and there was no better place to start than deep in the woods with an expert. Visit catskillfungi.com to schedule a...

In the 1970s, workers in PVC factories across the country began getting sick with a rare form of liver cancer.  While the plastics industry claimed they were unaware of what was causing that cancer, internal documents told a different story. Today we’re telling a story about corporate concealment, cancer, and of course, plastic.
