In this episode, we conclude our interview with Dr. Abigail Moore and Dr. James Hung. They explain why species concepts are important and how they are applied in their conservation-focused work with the Oklahoma Biological Survey.

In this episode we interview Dr. Abigail Moore and Dr. James Hung from the Oklahoma Biological Survey to learn about species concepts. In Part 1 we get their perspective on what a species is and why it can be hard to define.

In the 1500s, a disease called Cocoliztli devastated Indigenous communities in what is now Mexico. But what caused it? In this episode, we tell the story of Cocoliztli and how modern scientists used history, teeth, ancient DNA, and tree rings to identify the pathogen behind Cocoliztli, whose modern relatives still live among us.

Every day, your body fights a quiet, microscopic war. But how does the immune system know what to attack and what to leave alone? In this episode, Dr. Katriana Popichak, a researcher who focuses on how immune and inflammatory responses shape human health, helps us understand what the immune system is, how vaccines train it without giving you the disease, and how inflammation, meant to protect us, can sometimes be the root cause of some serious diseases. 

What do a Cold War assassination, a vengeful ex-spouse, and a hit TV show all have in common? A poison so powerful it can shut down protein synthesis entirely. In this episode, we break down the central dogma of biology and describe what protein synthesis is, how it works, and how one of the deadliest natural toxins known can bring the process to a complete stop.

The Gram stain is a cornerstone of microbiology labs, but what is it actually telling us, and why does it work? In this episode, Jimena and Emma unpack the history and logic of the Gram stain, explain how differences in bacterial cell walls drive the result, and share practical tips for improving your staining technique.

What do dogs and dandelions have in common? More than you’d think. Both are products of artificial selection. Sometimes it’s deliberate, and sometimes totally accidental. In this episode, we dig into how human choices (and mistakes) have shaped species in surprising ways. From the lovable evolution of dogs to the rise of unstoppable, herbicide-resistant weeds, we explore how artificial selection can create both best friends… and botanical enemies.

In this episode, we continue exploring microbiology by talking with Dr. Katriana Popichak about the tiny troublemakers all around us: bacteria and viruses. What are they? How do they infect us? And, more importantly, how can we push back against them? Grab some hand sanitizer and settle in as we untangle fact from fiction about microbes, antibiotics, vaccines, and the science of keeping microbes under control so they don’t ruin your day.
