Trina McMahon is a civic engineer and microbiologist. She studies microbial communities in lake water and wastewater treatment plants and tends to approach problems from an engineering perspective.

There is some discussion in this episode about the “Super Bowl Halftime Flush,” the phenomenon of thousands of Americans flushing the toilet during halftime, with the potential to damage municipal water pipes with the sheer volume of sudden water consumption. Though the halftime does incur significant peaks of water usage, the damage is unfortunately (or perhaps fortunately) an urban legend. Water treatment plants generally have bigger fish to fry than the Super Flush. Like morning showers and flooding.

Research specialist Celeste Mezera wears many hats. Like a beekeeping hat. Or a cute crocheted strawberry. She’s also worked in outreach, and currently works at the Wisconsin Energy Institute, where she keeps a lab running day to day.

Third year PhD student Sam Davison studies isobutanol, a jet-grade fuel fermented by the same yeast that puts the bubbles in bread and the ethanol in wine. This episode is perfectly on topic as we discuss brewing, gorillas, ocean acidification, and Pokémon.

P.S.: There’s some confusion in this episode about the term “bird focal.” Turns out it probably refers to the practice of choosing bird species representative of the overall ecosystem. Read more about it here.

Greetings from the past! This interview with professor and researcher Edward Hubbard was recorded last year, but busting neuromyths is always relevant. Edward works at the intersection of neuroscience, cognitive psychology, and educational policy. He came into the studio with plenty of stories about phonics and hamburgers and even taught me fraction division off the cuff.

Welcome to 2026! We’re ringing in the new year with an episode featuring environmental science undergraduate Devin Guthrie. Devin’s full of ideas about collaborative world building and scientific solutions designed with and for the communities they’re implemented in. His passion for urban ecology and environmental science has led him to watch pollinators amongst the hydrangeas of Chicago, operate telescopes, start a science fiction club, and do much, much, MUCH more.

Researcher, assistant professor, and host of the Neuro Network podcast Nick Burgraff studies opioid overdoses and how to prevent them. He’s here to answer all our host’s questions about naloxone (brand name: Narcan), the autonomic nervous system, and goat treats. He might even walk away with the prize for best science name mentioned before the year is over (hint: it’s a region of the brain a bunch of scientists named over a bottle of wine).

Selective Serotonin Reuptake Inhibitors (SSRIs) are commonly used to treat depression and other brain chemical imbalances, but how does that affect the other 90% of serotonin floating around the body? What about a developing body? PhD student McKenna Crossen talks about her work studying different ways SSRIs might affect placental and fetal development in mice.

Spooky scary skeletons send shivers down your spine and regulate your blood calcium levels. Professor and Principal Investigator of the Weaver lab Samantha Weaver answers all the questions you didn’t know you had about dairy cows, pac man, and osteoporosis

The background for this episode was all taken from my biocore unit on the endocrine system taught by Professor Weaver herself.
