Toxoplasma’s Stealth Mode: Hiding in the Brain
In this episode, we sit down with Dr. Robyn Kent, Assistant Professor at the University of Oklahoma College of Medicine, to explore how Toxoplasma gondii persists in the body long after infection. Dr. Kent breaks down the parasite’s chronic stage, where Toxoplasma forms cysts in tissues like the brain and muscle. But rather than simply “going dormant,” her research suggests these parasites may remain active, responsive, and far more dynamic than previously thought. We discuss tachyzoites, bra...

Paleopathology: A Window Into Ancient Diseases
In this episode, we sit down with Dr. Elizabeth Uhl, a veterinary pathologist at the University of Georgia’s College of Veterinary Medicine, to explore how disease leaves its mark across time. Dr. Uhl introduces us to paleopathology, the study of disease in ancient remains, and explains how animal bones, historical records, archaeology, and modern pathology can work together to reveal the health landscapes of the past. From pre-Columbian dog skeletons and canine distemper to horses, wartime d...

The World’s Most Successful Parasite: Inside Toxoplasma’s Weird Biology
In this episode, we sit down with Dr. Diego Huet, an associate professor in the College of Pharmacy at the University of Georgia, to explore Toxoplasma gondii. It's often called the world’s most successful parasite. Infecting up to a third of the global population, Toxoplasma is both incredibly common and largely invisible. Dr. Huet breaks down how it spreads, why most people never know they have it, and how it can persist in the body for life by forming dormant cysts. We also dive into the p...

Rebuilding Immunity: The Thymus, Your Immune System’s Hidden Architect
In this episode, we sit down with Dr. Nancy Manley, Director of the School of Life Sciences at Arizona State University. Before ASU, she spent over 20 years at the University of Georgia, where she served as Head of the Department of Genetics and a Distinguished Research Professor studying the thymus. We explore one of the body’s most overlooked yet essential organs, the thymus, and how it builds and shapes the immune system over time. Dr. Manley breaks down why this organ is far more dynamic ...

An Open-Source Pandemic: Genomes, Metadata, and Real-Time Outbreak Science
In this episode, we sit down with Dr. Justin Bahl, a UGA Professor of Epidemology and Biostatistics. David and Kim explore how modern epidemiology uses genomic data and statistics to track the spread of infectious diseases. From studying fungi on palm leaves across Asia and Australia to analyzing viral genomes during the 2009 H1N1 pandemic, Dr. Bahl shares how global field experience and biostatistical tools come together to reveal how pathogens move through populations. We discuss molecular ...

When Neutralizing Isn’t Enough: The Immunology of Alphavirus Defense
The hosts sit down with Dr. Julie Fox, Chief of the Emerging Virus Immunity Unit at NIAID, National Institutes of Health, to explore the science of alphavirus immunity and what antibodies really do in the context of alphavirus infection. From chikungunya virus and its debilitating joint disease to broader mosquito-borne alphaviruses, Dr. Fox explains why these viruses are powerful models for studying immune protection. We move beyond the traditional view of antibodies as simple neutralizers a...

The Hidden Empire of Parasitoid Wasps
Parasitoid wasps are some of the most successful organisms on Earth, even if most of us never notice them. In this episode, Dr. Michael Strand from the UGA Department of Entomology takes us inside the hidden world of parasitoid wasps. These insects lay their eggs in other insects and rely on domesticated viruses to suppress host immune systems and control development. We explore how these virus–wasp partnerships evolved over millions of years, why they have made parasitoid wasps incredib...

From Pathogen to Prescription: Reimagining E. coli
What if your gut bacteria could become medicine? In this episode, a UGA microbiologist, Greg Phillips, reveals how engineered probiotic E. coli can produce L-dopa, the frontline treatment for Parkinson’s, directly inside the gut. We explore the gut–brain connection, the power of the microbiome, and how living microbes could become the next generation of drug delivery systems. From World War I probiotic strains to modern genetic engineering, this episode takes you inside a bold new frontier ...
