BioTA Podcast

Every few years, we hear that El Niño is on the way! But what does that actually mean? And what is El Niño, anyway? In this episode, Dr. Gary McManus of the Oklahoma Mesonet takes us beyond the headlines and hype to explain what El Niño is, what it isn’t, and how this recurring climate pattern can shape the weather we experience.

In part two of our interview with neurobiologist Dr. Lemon, we learn more about taste and flavor. And to spice things up, we talk about how the fiery sensation from eating peppers isn’t triggering taste buds but instead is caused by capsaicin changing how pain receptors in your mouth work.

In this episode we interview neurobiologist Dr. Chris Lemon to learn about how receptors and neurons in your mouth work together and interact with other sensory systems to detect taste and give the sensation of flavor. 

In Part 2 of our interview with Dr. Stein, we explore some of her research on how plasticity helps organisms survive in their environments, what it reveals about the importance of biological flexibility, and where this field needs to go next to answer remaining questions about this important trait.

At its core, phenotypic plasticity is one genotype, multiple outcomes. But what does that actually look like in real biology? In this episode, Dr. Laura Stein introduces phenotypic plasticity: what it is, how it works, and why it is important that organisms aren’t fixed in form or function.
