Episode description

When it comes to PFAS chemicals—known as “forever chemicals”—we often hear that they’re used in nonstick coatings, flame retardants, and stain repellants. But those examples can hide the truth of just how widespread their use has been in modern life.

A new season of the “Hazard NJ” podcast looks at the origin story of PFAS chemicals, and the accidental discovery of PTFE—aka Teflon—in a DuPont laboratory in southern New Jersey. “Hazard NJ” host Jordan Gass-Pooré joins guest host Kathleen Davis to talk about the history of PFAS, their effect on the environment and health of New Jersey residents, and work towards cleaning up the PFAS mess.

People are finding all sorts of uses for mushrooms these days, but we’re going to focus on two of them: how scientists are using them in robots and how playwrights are using them in theater. A few weeks ago, SciFri producer and host of our “Universe of Art” podcast D Peterschmidt moderated a panel at the Science In Theater Festival in Brooklyn, New York.

The festival is put on by a company called Transforma Theatre that stages science-inspired plays. Each year, they pair playwrights with scientists to make short plays that explore the research focus of the scientist.

Director and playwright Hannah Simms was paired with Dr. Andrew Adamatzky, a professor of unconventional computing, who’s learning how to connect various parts of nature, like mushrooms, to computers, and consulted with Hannah during the writing process. The play, called “Fruiting Body,” is about a fungal-computing scientist who, while pregnant, creates a fetal heart monitor powered by mycelium, which turns out to be sentient. While the concept is definitely science fiction, it is based on real unconventional mushroom research.

D talks with Hannah to learn why she wanted to explore her pregnancy through the lens of mushroom research. They’re also joined by Dr. Anand Mishra, a research associate at Cornell University’s department  of mechanical and aerospace engineering, who explains how he helped build a robot that’s powered by king oyster mushroom mycelium.

Transcript for this segment will be available after the show airs on sciencefriday.com.
