Nice Genes!
Hosted by Genome BC · EN
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.

Genomic Repeat: Slipping Through the Spectrum - Rethinking the Divide in Autism Diagnoses
Apr 700:33:11Tap to summarizeThis episode was originally released on November 5, 2024Dr. Hannah Belcher was already studying autism she found out she herself was Autistic. Getting her diagnosis felt like everything suddenly clicked… but why did it take so long to get answers?In this episode, Hannah shares her journey and talks about how many Autistic people, especially women, learn to mask their true selves to fit in– causing them to slip through the diagnostic cracks. Then, we invite Dr. John Constantino to break down the genetic underpinnings of Autism Spectrum Disoder and related conditions like ADHD—and how science is shaking up the genomic picture of what we thought we knew about this male-female bias.From outdated theories to “refrigerator mothers,” join hosts Dr. Kaylee Byers and Dr. Rackeb Tesfaye as they comb through the tangled web of sex bias and ask whether our current methods of studying neurodiversity is actually addressing the questions the people with ASD want answered?A Note on Language:When talking about Autism - semantics matter. So, it’s important to recognize the nuances of language. Many people in the Autism community prefer identity-first language, such as "Autistic person," as it centers Autism as a core part of their identity. Others, however, may prefer person-first language, like "person with Autism," which places the individual before the condition. We’ve used both forms of language in this episode, and we encourage respecting individual preferences by asking what each person is most comfortable with. For more on this, check out resources like the National Institutes of Health’s guide on writing respectfully about identity and the Autistic Self Advocacy Network’s explanation of identity-first language.Additionally, when we refer to ‘Autism risk’ in the context of academic research, it typically means an increased genetic likelihood of receiving an Autism diagnosis. However, we recognize that "risk" can imply a negative connotation (which we do not support.) Instead, we aim to discuss Autism in ways that honour the neurodiversity of all individuals.Lastly, regarding sex differences in Autism diagnoses, in this episode, we’re talking specifically about sex assigned at birth. Although we mention gender, we want to be clear that we aren’t exploring how Autism diagnoses may vary by gender identity—that area remains understudied! So, our conversation is focused on differences between males and females, and we look forward to seeing more research on the richly complex interactions between gender identitiy and neurodiversity in the future.Highlights:(6:32) Growing up undiagnosed(18:52) The genetic underpinnings of Autism and related neurodiverse conditions(22:20) Debunking the “female protective effect”(26:37) A biased assessmentResources:1. ‘Taking off the Mask: A Practical Guide for Managing Autistic Camouflaging and Mental Health‘ - Dr. Hannah Belcher2.

Genomic Repeat: Germ Spotting - Tracking diseases using genomics
Feb 1000:46:49Tap to summarizeThis episode was originally released on December 13, 2022Stop the presses! New research shows that viruses locked in the Arctic permafrost for thousands of years have the potential to infect present-day organisms. Accompanied with a warming planet, this issue is really starting to thaw out. So what can brave scientists and institutions on the frontlines of tracking diseases do about it? And how can understanding our genomic history with diseases over thousands of years better prepare us in the fight to overcome them?Dr. Kaylee Byers starts our journey by slinking into a disease-tracking genomics lab at Simon Fraser University to meet Dr. Michael Trimble and Dr. Will Hsiao to understand the challenge of outpacing the rapid evolution of viruses. Then she pops across the ocean to speak with Dr. Birgitta Evengård and Dr. Jean-Michel Claverie about whether the Pandora's box of ancient diseases frozen in the arctic have the potential to become the next global outbreak as temperatures warm. Plus, we unearth ancient burial sites in Vietnam with Dr. Melandri Vlok, to investigate how climate change exacerbates the tension between human health and pathogens.Special thanks to Dr. Will Hsiao and Dr. Michael Trimble for allowing us to record with them at Simon Fraser University.Resources:1.

The Music That Moves Us
Feb 300:43:09Tap to summarizeListening to and creating music is one of the most universal human experiences. It gets stuck in our heads, makes us cry in the car, and has the power to bring people together – sometimes without even a single word. So for something so deeply ingrained in us - IS IT... ingrained in us? like, in our DNA? it raises a big question: is our connection to music something we learn… or something written into our DNA?In this special bonus live episode, host Dr. Kaylee Byers takes the pod on stage for the very first time to explore the science of music. Joined by neuroscientist Dr. Lara Boyd, clinical geneticist Dr. Alison Castle, and (virtually) behavioural geneticist Dr. Miriam Mosing, our panel unpacks how music shapes and rewires our brains, why it can be such a powerful tool for therapy and lifelong learning, what genes can (and definitely can’t) tell us about musicality– and why music even exists in the first place.So warm up those vocal cords, and get ready to sway in your seat… this is Nice Genes! live.Special thanks to musician (and recovering physicist) Dr. Martin Austwick for the live musical magic throughout the show.-Highlights(7:24) How Opera Training Influences the Brain(10:30) Music’s Role in Memory and Dementia Prevention(22:27) Heritability of Musical Behaviour(36:24) If we could identify specific musical genes, should we?-Show Notes/Resources:1.

TB Trails and Tails
Dec 1600:35:08Tap to summarizeWhy Tuberculosis is still the most deadly infectious disease.Attention, DNA detectives! We’ve got a rat on the loose – but don’t worry, not the snitching, double-agent kind. We’re talking about the whiskered, hyper-skilled, tiny agents who aren't snitching - they're sniffing out one of the world’s deadliest diseases: tuberculosis (TB).Tuberculosis might sound old-timey, but it’s still the globe’s top infectious killer– growing tougher, more drug-resistant, and hitting hardest where access to care falls short. So for our Season 5 finale, host Dr. Kaylee Byers digs into TB’s fascinating backstory, and teams up with microbiologist Dr. Jennifer Guthrie to figure out why this ancient disease still has such a tight grip, and how genomics is helping track its every move. Along the way, Dr. Zolelwa Sifumba shares her story as a multidrug-resistant TB survivor, and how her treatment journey fuels her advocacy today.Buckle up: this investigation has it all : science, politics, global inequities… and a squad of extraordinary rats.Special thanks to APOPO for sending us field recordings and interviews from their HeroRAT training program.Highlights(3:42) The history of TB(8:19) Why TB sits at the top of the global disease podium(15:30) Meet Zolelwa - a multi-drug-resistant TB survivor(30:48) The power of education–Show Notes/Resources:1.

Menopause Mysteries
Dec 200:30:49Tap to summarizeTurning up the heat on a life stage science is still catching up to.Ok, most of us may have gotten “the period talk.” But the “menopause talk?” Not so much. For something that half the world will experience, menopause and perimenopause are still wildly misunderstood. Luckily, the DNA detectives are finally reopening a mystery that’s been overlooked for too long.In this episode, Dr. Kaylee Byers unpacks the science behind menopause. She calls on educator Shirley Weir to understand what menopause and perimenopause actually are– and why so many people feel dismissed when they try to get answers. Plus, reproductive genomics researcher Dr. Aspasia Destouni reveals what our genes (and a few unlikely informants– from orcas to naked mole rats) can teach us about the rebellious internal clock that drives ovarian aging.Special thanks to Andrea Rathborne- creator, host and producer of the Half Betty podcast.A note on language: This episode often uses the terms “women” and “female” interchangeably, but we want to acknowledge that menopause is not experienced exclusively by women. People of various gender identities can go through perimenopause and menopause, and it's important to be inclusive in how we talk about this life stage.Resources: Menopause and perimenopause can feel isolating, and support isn’t always easy to find.

Gut Check
Nov 1800:31:42Tap to summarizeWhat 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.Highlights(4:00) The bacteria behind food poisoning(10:13) How genomics helps track foodborne outbreaks(16:35) The microbiome in all its glory, and the gut-brain connection(23:59) Some poo-ticular scientific treatments–Resources1.

Bite Club
Nov 400:32:57Tap to summarizeHow 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.Highlights(5:51) Vector disease dynamics: The pathogen, the vector, and the host– a love triangle.(13:10) A neglected disease you may have never heard of.(17:20) Ancient DNA uncovers the tale of an opportunistic pathogen and a surprising partner in crime.(26:20) What changes to our environments does to our disease landscape–Resources1.
