What genomics can tell us about food safety, the microbiome, and the mind.You’ve heard the saying, “you are what you eat”... Well, our gut microbes take that very literally. If you’ve ever gone on vacation, eaten something tasty, and next thing you find yourself bonding with a bathroom floor, you’re not alone. Food poisoning might occasionally make for a good story later, but it’s a serious issue that lands millions of people in hospitals every year– and tracing the culprit isn’t always as simple as pointing at last night’s tacos.In this episode, Dr. Kaylee Byers chats with microbiologist Dr. Lawrence Goodridge, who explains how genomics helps track foodborne outbreaks – from the harmful bacteria in our food to the microbes living inside us. Then, Dr. Mary Sco. dives into the science of the gut-brain connection, revealing how your gut and brain are constantly in conversation.So grab a snack, and get ready to stomach the science.Click here for tickets and more information about the Nice Genes!

Bite Club
How vector-borne diseases spread– and the critters that carry themMalaria, Lyme disease, dengue, Zika… what do they all have in common? They’re what we call vector-borne diseases– spread to us by tiny, bite-happy arthropods. These little troublemakers are responsible for 17% of all infectious diseases worldwide, and with climate change and urbanization on the rise, they’re becoming an even bigger threat.In this episode, Dr. Kaylee Byers sits down with insect investigator Dr. Gonzalo Vazquez-Prokopec to untangle the intricate web of vector-borne disease dynamics, and explain what makes these insects such masterful disease spreaders. Then, Dr. Pooja Swali shares how ancient DNA from thousands of years ago revealed a pathogen’s curious evolutionary switch from one creepy crawly to another.From mosquitoes to ticks to the not-so-affectionate kissing bug, every insect in this lineup is guilty of something– and genomics is helping us figure out what.Click here for tickets and more information about the Nice Genes!

Why Athletes Collapse
The genetic clues behind sudden cardiac arrest in young individualsEvery so often, we see headlines about an elite athlete collapsing mid-game. The crowd goes silent, emergency crews rush to the field, and everyone’s left wondering: how could this happen? The truth is, sometimes a hidden heart condition written deep in our DNA will unmask itself on the field.In this episode, Dr. Kaylee Byers sits down with sports cardiologist and cardiogeneticist Dr. Prashant Rao to explore the genetic roots of sudden cardiac events in young athletes. Together, they unpack the most common underlying genetic conditions responsible, what genomics is revealing about the specific genes involved, and the ongoing debate around genetic screening. Plus, the remarkable story of JJ: a young wrestler who survived cardiac arrest thanks to his early genetic diagnosis and fast-acting friends.Listen in to learn why these devastating events happen, and how genomics is helping keep athletes safely in the game.Click here for tickets and more information about the Nice Genes!

Genetics and the Silver Screen
How medical dramas shape the way we think about genomicsMedical dramas have been a staple of television for decades, from iconic primetime hits like Grey’s Anatomy and HOUSE, to newer favorites like The Pitt. It’s easy to get swept up in the high-stakes surgeries, love triangles, and melodramatoc monologues– but when it comes to the science, a second opinion might be in order.In this episode, host Dr. Kaylee Byers sets out to investigate how these kinds of TV shows shape our perceptions of science. First up, Watson script consultant Dr. Krysta Coyle breaks down some of the biggest genomic missteps medical dramas make, and dishes on what it’s like to be the science voice on set. Then, Ayden Eilmus, a bioethicist and medical drama scholar, explores the evolution of genetics on TV, from problematic eugenics-era storylines to the more complex and ethically rich portrayals we see today.Hit "play" to uncover how our guilty-pleasure binge watches can have a bigger impact than just entertainment.Click here for tickets and more information about the Nice Genes!

Babies and Breakthroughs
How new genomic approaches are helping diagnose and treat our tiniest patientsWelcoming a new baby brings boundless love, joy, and the usual sleepless nights of early parenthood. But in the NICU, when a newborn is unexpectedly sick, it’s the uncertainty that keep parents awake.In this episode, our investigation takes us inside the neonatal intensive care unit, where genomic tools are mapping medical mysteries in record time. You’ll hear the remarkable story of “Baby KJ,” the first newborn to receive a personalized CRISPR treatment; insights from pediatric geneticist Dr. Tara Wenger on how new approaches to testing are changing care; and the story of Meredith Thomas– a mother whose fight for answers helped uncover a diagnosis that saved her daughter’s life.From faster diagnoses to fairer care, join Dr. Kaylee Byers to learn how these genomic breakthroughs are redefining what’s possible for newborns and their families.Click here for tickets and more information about the Nice Genes!

From healthcare and biotechnology to forests and fisheries, the evolving study of genomics is leading to some of the most exciting and world-changing discoveries in science and medicine. Like – did you know that your individual genomic signature can help determine the healthcare treatment you receive? Or that mapping the genomes of trees can inform forest management?
But while the study of genomics holds great promise for the health of people, animals, and the environment, it also confronts us with big questions: How do we study genetic patterns in a way that respects sensitive genetic information, history, and equity? How do we use the power of genomic research to fight climate change? Save the salmon?
Join Dr. Kaylee Byers – a self-described “rat detective” and science communicator as she guides you through fascinating conversations about the what, the why, and the how of genomics.
