In this mini recap of Episode 49, Joe, Nick, and Georgia return to the wild intersection of cardiac science and superhero world-building, revisiting their conversation with bioengineer Rengasayee “Sai” Veeraraghavan. They also clean up a few nerdy misfires from the full episode, including the adrenal-versus-pituitary mix-up and the moment Joe accidentally described the origins of life using a term that actually refers to radioactive decay. That detour opens the door to panspermia, radiopanspermia, and exogenesis.
The crew shares the media they’ve been consuming, from Stranger Things prep episodes to rewatching Blade Runner, Rick Therrio’s graphic novels, Superman (2025), and Nick’s slow, steady descent through Gilmore Girls. With only two episodes left in the season, Gremlins science, and a pajama-party holiday debate recap episode, they look forward to the start of Season 3.
The Heart of a Superhero
In this episode of Rabbit Hole of Research, Joe, Nick, and Georgia team up with special guest Rengasayee “Sai” Veeraraghavan, professor of biomedical engineering at The Ohio State University and head of a nano-cardiology lab, to ask a deceptively simple question:
Check out what the RHR crew is creating:
Joe:
Red Line: Chicago Horror Stories Anthology featuring a new story by Joe!
Chicago Writers Association Podcast:
Essay by Joe: From Beyond Press: Specific Knowledge: Jotham Austin, II, PhD on Transformations in Fiction
Joe explores how many calories it would take to transform into monsters across sci-fi and horror—think 222 Big Macs and tubs of Cherry Garcia.
