Nice Genes!

The 200-Year Old Whale

Bowhead whales can live for nearly 2 centuries, weigh as much as 22 elephants, and– surprisingly– rarely get cancer. So what’s their sea-cret? Sarah Lando from Genome BC brings us the splashy new genomic research behind these Arctic giants’ longevity, and what it could mean for the future of cancer research.Resources1. “This whale lives for centuries: its secret could help extend human lifespan”- Nature2.

Genomic Repeat: Germ Spotting - Tracking diseases using genomics

This 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

Listening 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

Why 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.
