Scientists in Michigan are developing technology to use microbes to convert plastic waste and inedible plant material into nutritious protein, fats, and sugars. The project aims to simultaneously address the global plastic pollution crisis and food shortages. The hosts express skepticism about the palatability and safety of eating plastic-derived nutrients.

A California startup called Air Protein, led by CEO Lisa Dyson, claims to create meat alternatives using microbes that consume carbon dioxide, oxygen, and nitrogen. The process results in a protein-rich flour that can mimic chicken or steak. Dvorak identifies the base organism as a type of "slime mold" and expresses disgust at the concept of lab-grown protein.

Science journalist David Quammen and author Sonia Shah discussed the link between environmental crises and zoonotic diseases. They explained that bats serve as "reservoir hosts" for viruses like SARS, MERS, and the current coronavirus, often without showing symptoms themselves. As human activity like deforestation increases contact with wildlife, these microbes are more likely to "spill over" into human populations.

A personal account describes severe gum recession and dental pain occurring immediately after quitting a long-term smoking habit. A dentist performed an emergency deep cleaning to remove microbes lodged in the receded gums. The narrative serves as a warning to long-term smokers about potential oral health shifts during cessation.

Noodle Theory in Oakland is recognized for its cleanliness and affordable menu after two years of operation. The discussion transitions back to Archer Daniels Midland's biotechnology division, which uses microbes to convert corn dextrose into lysine. This process, described as "bugs eating dextrose and crapping lysine," is essential for bulking up livestock for companies like Tyson and Conagra.
