Nice Genes!

Managing an Invisible DiseaseIs there a Zombie moose on the loose?! Not quite... But there is something lurking in the woods that has our “deer” friends shakin' in their hooves. Chronic Wasting Disease (CWD) is a 100% fatal illness that’s creeping its way through cervid populations, and it’s nearly impossible to spot. Luckily, wildlife biologists like our guest Cait Nelson from the BC Ministry of Water, Lands, and Natural Resource Stewardship are on the case.In this episode host Dr. Kaylee Byers and Cait Nelson talk about the clever scientific tools that are helping us track CWD– from grapefruit spoons to genomics! We’ll also hear from Alfred Joseph from the ʔakisq̓nuk First Nation and member of the Ktunaxa Tribe, who explains how CWD is more than just a threat to wildlife, but also has deep implications for community and food sovereignty.Join us on a pun-packed hunt to find out how we can get ahead of this deadly and stubborn disease, one dead head at a time.Special thanks to Jeff Berdusco, CWD Coordinator in the Kootenay region for providing field recordings for this episode.–Highlights(4:46) What is CWD?(13:10) A threat to cultural independence.(17:48) Tracking a silent killer.–Resources:1.

Forensic Methods in Disaster RecoveryContent warning: this episode discusses forensic science and the identification of human remains that may not be suited for all audiences.Natural disasters can strike without warning. And when they do, they can leave destruction, displacement, and loss of life in their wake. First responders rush to help those in need, while forensic scientists face the difficult but incredibly important task of identifying human remains– a process known as Disaster Victim Identification (DVI).In this episode, we’re going back to 2004, to the largest DVI event in recent history. Host Dr. Kaylee Byers sits down with Chief Forensic Odontologist Dr. Dirk van der Meer as he shares his first-hand experiences of helping identify victims following the devastating tsunami in Thailand. Then, how are genomics reshaping forensic identification today? We head to Australia to hear from Dr. Dadna Hartman about a new tool that’s offering answers—and closure—to families, faster than ever. Join us for a behind-the-scenes look at the important and fascinating world of forensic science.–Highlights(6:51) On the scene after the tsunami(16:01) A speedy genomic tool(23:00) Beyond the science–Resources:1.2004 Indian Ocean earthquake and tsunami: Facts and FAQs- World Vision2.

Rethinking the Divide in Autism DiagnosesDr. 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 assessmentLearn-A-Long: https://bit.ly/4g9kCRaResources:1. ‘Taking off the Mask: A Practical Guide for Managing Autistic Camouflaging and Mental Health‘ - Dr. Hannah Belcher2.

The Deceptive Seduction of Femme Fatale FirefliesIn the buzzin’ firefly nightlife scene, neon lights glow bright and sparks fly. But, there’s murder on the dancefloor… The infamous 'Femme Fatale' firefly has mastered the ultimate bait-and-switch seduction strategy, and these sly flies (that are really beetles, actually) aren’t interested in a happily ever after, instead they’re looking for a ‘one-bite stand.’Get consumed in this episode by one of nature’s flashiest insects. Join host, Dr. Kaylee Byers, as she chats with Dr. Sarah Lower about the enchanting world of glow beetles. And later, Dr. Peter Andolfatto reveals how genomics is uncovering the secrets behind how Femme Fatale fireflies have evolved to resort to such drastic measures. Plus, find out what studying firefly toxin DNA could mean for future medical breakthroughs.–Highlights:(5:40) Dr. Sarah Lower covers some firefly basics(12:11) Dr. Lower on the deceptive strategy of the Femme Fatale Fireflies(19:21) Dr. Andolfatto explains how fireflies have evolved difference resistance strategies to toxins(26:02) Dr. Lower on how to get involved in firefly conservation–Learn-A-Long: https://bit.ly/3OODRUb—Resources:1.
