Show overview
The Gastronauts Podcast has been publishing since 2019, and across the 6 years since has built a catalogue of 43 episodes, alongside 1 trailer or bonus episode. That works out to roughly 25 hours of audio in total. Releases follow a roughly quarterly cadence, with the show now in its 5th season.
Episodes typically run thirty-five to sixty minutes — most land between 30 min and 45 min — though episode length varies meaningfully from one episode to the next. None of the episodes are flagged explicit by the publisher. It is catalogued as a EN-US-language Education show.
The catalogue appears to be on hiatus or wound down — the most recent episode landed 1.2 years ago, with no new episodes in over a year. The busiest year was 2020, with 12 episodes published. Published by Gastronauts.

Because all who eat, do so to move. We move in search of the next meal, the next idea, the next big thing. Join us as we uncover what moves experts on gut brain matters.

Dr. Ranier Gutierrez is a Professor in the Department of Pharmacology at CINVESTAV in Mexico City. His life’s work is centered around the basic human need to control our appetite. (For food that is, there is no need to control your appetite for discovery!!! 😉) In his laboratory, they use cutting edge technology to to read minds as the subject eats in order to better understand what is the circuitry that connects feeding to joy.
S5 Ep 8Episode 39: The Motivation Matrix
Dr. Michael Krashes is a Senior Investigator at the NIDDK in the NIH. His laboratory is on a mission to decipher the wiring diagram for hunger. His current work seeks to uncover the secrets behind our most primal instincts for survival, such as, the oscillating interactions between self-preservation and food-seeking to optimize behavior. His research is shedding light on the intricate mechanisms that govern our relationship with food.
S5 Ep 7Episode 38: The Bloodthirsty Brain
Dr. Laura Duvall (Columbia) investigates the neurobiological mechanisms underlying mosquito behavior, including the regulation of host-seeking after blood-feeding, circadian and seasonal biting rhythms, and mating behavior. She employs pharmacological and genetic approaches to uncover the neuropeptide pathways and anatomical circuits involved in these behavioral switches, shedding light on fundamental questions regarding mosquito biology. The laboratory also works to address the signaling mechanisms responsible for inhibiting re-mating and preventing interspecies mating, crucial for understanding reproductive strategies and interspecies competition among mosquitoes.
S5 Ep 6Episode 37: Targeting Visceral Pain
Dr. Scott Waldman's research at Thomas Jefferson University explores the mechanisms underlying visceral pain and how neuropod cells communicate with innervating spinal neurons. His work focuses on the role of the specific protein GUCY2C as a mediator of activity and a potential therapeutic target for treatment.
S5 Ep 5Episode 36: Survival Signal Showdown
Dr. Nick Betley's work at the University of Pennsylvania focuses on how hypothalamic circuits are regulated to influence food intake. On the podcast, we discuss the integration of pain and hunger in hunger circuits—examining when pain outweighs hunger and vice versa.
S5 Ep 4Episode 35: To Sense or Not To Sense
The 2023 Bite Size Summit, featuring four amazing early career scientists, Drs. Servin-Vences, Scavuzzo, Lough and Biswas, who study biological sensors for stretch, the functions of glial cells and the fascinating development of senses or lack thereof!
S5 Ep 3Episode 34: Tasting the World
Dr. Greg Suh explores the fascinating world of how brains process external stimuli and generate behavioral responses. Using the fruit fly and advanced genetic tools, his group at KAIST investigates the neural substrates behind innate behaviors. They're also delving into the identification of internal sensors for nutritional value in both fruit flies and mice, shedding light on how mammals perceive and respond to nutrients.
S5 Ep 2Episode 33: Science of Sour
Emily Liman, Ph.D., is a Professor of Biological Sciences at the University of Southern California. Dr. Liman is a world-renowned sensory neurobiologist who has advanced our understanding of taste perception through her groundbreaking discoveries including that of the OTOP channel—a key player in our ability to perceive the sour taste of a juicy lemon.
S5 Ep 1Episode 32: The Psychedelic Synapse
Andrea Gomez, Ph.D., is an Assistant Professor at the University of California Berkeley. Andrea’s laboratory seeks to understand the mysteries of the mind at the intersection of psychedelics and plasticity. The laboratory uncovers how these trippy compounds shake up our synaptic playground by using a combination of molecular biology, functional imaging, and slice electrophysiology to understand neural plasticity in neural degeneration and the potential therapeutic use of the active components in psychedelics.
Episode 31: A Plant-Based Future
Join our conversation with Ilya Raskin, famous for his work on plant growth regulation, plant immunity to diseases, phytoremediation, and, in the last decade, for his research in plant-derived functional foods and medicines. He is also actively involved in international bioexploration, conservation and is an amazing photographer!
S4 Ep 10Episode 30: Intestinal Inflammation Interface
Join us in our chat with Dr. Brian Gulbransen, from Michigan State University. His laboratory studies how inflammation in the nervous system leads to long-term changes in gastrointestinal function; and how glia, immune cells and the neurons in the gut communicate.
S4 Ep 9Episode 29: The Unseen Controllers
Dr. Maude David is an Assistant Professor at Oregon State University. Her laboratory studies the microbial gut-brain connection, and how microbes impact behavior, specifically in Autism Spectrum Disorder and anxiety.
S4 Ep 8Episode 28: Engineering Cyborgs
Join us in our talk with the amazing Dr. Greg Gage, CEO and co-founder of Backyard Brains, an engineer and neuroscientist designing open-source tools to bring advanced neuroscience into classrooms and designing robots that help us understand how neurons produce behavior.
S4 Ep 7Episode 27: Wiggle the Mind
Join us in our talk with Dr. Polina Anikeeva, a material scientist and engineer leading a group at MIT that develops cutting-edge devices to understand and modulate the brain and other body systems.
S4 Ep 6Episode 26: Carve Your Path
Our very own 2022 Bite Size Summit, featuring four amazing early career scientists studying the brain-body connection and the effects of microbiome and diet across different species, join us in our conversation with doctors Valerie Darcey, Aki Ohdera, Nikki Pelot and Shawn Spencer.
S4 Ep 5Episode 25: Follow Your Nose
The road to scientific discovery is never a straight line, join our conversation with Dr. Heidi de Wet from Oxford, a researcher of the mechanisms of blood sugar and body weight regulation.
S4 Ep 4Episode 24: Good Vibes Only
What do sensory deprivation tanks and therapeutic ingestible vibrating pills have in common? Learn about your "gut feelings" and interoception with Sahib Khalsa, M.D., Ph.D. of the Laureate Institute of Brain Research.
S4 Ep 3Episode 23: Monarch Butterfly, M.D.
Dr. De Roode is a Professor of Biology at Emory University. He is perhaps the world’s foremost expert on monarch butterflies. His team is documenting how these beautiful creatures use plants for self-medication to treat themselves and their offspring against parasites.
S4 Ep 2Episode 22: Squirrels In Space
Tune into our talk with Dr. Eleva Gracheva on how studying the hibernation of ground squirrels can lead us to new insights about our own health and eating disorders, and in the future, help us create new tools for deep-sea diving and space exploration.
S4 Ep 1Episode 21: Sharing Your Vision
