The genetic clues behind sudden cardiac arrest in young individuals

Every 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.

How medical dramas shape the way we think about genomics

Medical 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.

How new genomic approaches are helping diagnose and treat our tiniest patients

Welcoming 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.

How wastewater surveillance is tracking diseases outbreaks

When you flush your toilet, where does the waste go? Down the pipes, through the sewers, and into a… lab? That’s right, hidden in our collective waste is a archive of genomic clues revealing our health, habits, and maybe even happiness levels.

In this episode, host Dr. Kaylee Byers teams up with Dr. Jess Steier from the Unbiased Science podcast as they dive into the world of wastewater surveillance. Along the way, they enlist a seasoned “poo detective,” Dr. Natalie Prystajecky, who wades through some wastewater 101, and how sewage can tip us off to disease outbreaks before symptoms even start. Then, Dr. Yemisi Bokinni brings the investigation to the not-so-small town of Makoko, Nigeria, where a new genome sequencing lab is chasing an old culprit: polio.

From your neighbourhood sewers to global health and future pandemics, we're using genomics to identify poo dunnit.

Every mystery leaves a trail of clues. Fingerprints, call logs, maybe some tire tracks… or, of course, DNA. And when it comes to mysteries about our health, there are no shortages of leads to chase.

This season, join host, Dr. –or Detective– Kaylee Byers and the Nice Genes! CSI unit as we investigate the genomic breadcrumbs shaping the way we age, treat diseases– and even watch TV. We’ll uncover how “poo water” can tip us off to pandemics before they spread, to why some of the fittest athletes suddenly collapse on the field. And if you thought you smelled a “rat,” well, you’d be correct. Because we'll also learn how our rodent sidekicks are helping us sniff out the world's deadliest infectious disease.

Houston, we have… a microbe? A mysterious bacterial species has shown up aboard China’s Tiangong Space Station, and Dr. Kaylee Byers and Sarah Lando are hopping into the Nice Genes! mothership to investigate. Where did this intriguing new organism come from? Did it evolve in orbit? And what does it mean for the future of space travel?

The Importance of Biodiversity

Description:

This episode was originally released on October 31, 2022

Conservation is often about protecting the species that still wander around our Earth. But what about those that once did but have gone extinct? In this Halloween-inspired episode, we take a look into how one spooky idea has gone from science fiction to science fact, de-extinction style.

Dr. Kaylee Byers takes us to the upside-down world of wild animals in Australia. She sits down with Dr. Axel Newton whose research addresses how to resurrect a species that has been extinct for nearly a century. Also joining her is Dr. Carolyn Hogg who uses the latest genomic technology to understand the impacts of reintroducing endangered species into their native habitats. In this wacky tale of resurrection and 'devils' will the spirit of scientific discovery mean incredible changes for the future, or is a line being crossed that we can't come back from?
