Dogs and Dandelions – #048 Oct 24, 2025

Show notes

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.

Microbes, Viruses, and Germs… Oh My! – #047 Aug 19, 2025

Show notes

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.

Antibiotic Resistance: Monsters We Created? – #046 Jul 24, 2025

Show notes

In this second episode on antibiotics, the Infectious Minds duo explores an unintended, and occasionally terrifying consequence of these life-saving drugs, antibiotic resistance. What exactly is antibiotic resistance? How did it arise? And what kind of microbial “monsters” are we now up against? This episode unpacks the fundamental science behind one of medicine’s most urgent and literally evolving threats.

Antibiotics: The Solution We Found – #045 Jul 12, 2025

Show notes

For most of human history, even a simple scrape could turn deadly. Then came antibiotics. They were powerful, mysterious, and world-changing. But what exactly are they? Where did they come from, and how do they work? In this episode, the Infectious Minds student podcasters step into the studio to bring you the science and share the story behind one of medicine’s most important discoveries.

Vampire Bats, Rabies, and You – #044 Apr 18, 2025

Show notes

In this episode, we sink our teeth into the world of vampire bats and rabies. Two fearless researchers take us from their jungle field sites to the lab as they track how hungry bats can spread viruses, including rabies! They also share what to do if you ever encounter a bat, raccoon, or other suspicious critter lurking in your home or yard. It’s a tale of blood, viruses, and the intersection of wildlife and human health.

DIY Evolution – Darwin and Artificial Selection – #043 Mar 25, 2025

Show notes

From racehorses to fancy pigeons, Darwin saw selective breeding as humans applying one of nature’s most powerful forces, evolution by natural selection, to change domesticated species. This episode explores how Darwin used evidence of what he called artificial selection to support his ideas on natural selection and evolution, how modern genetics backs him up, and why selection is constantly shaping the world around us.

Genotypes and Phenotypes in the Biology Zone – #042 Mar 14, 2025

Show notes

In this Twilight Zone-inspired episode of BioTA, two biology students prepping for lab encounter a pair of unexpected space travelers who want help unraveling a mystery: Why do some bacteria defy antibiotics while others perish? Why do some plants tolerate herbicides while others shrivel? With a crash course in the concepts of genotypes and phenotypes, the students explain some of the basic principles that life on Earth follows (most of the time).

Jurassic Park Genetics – #041 Feb 25, 2025

Show notes

This episode uses the sci-fi action film Jurassic Park as a springboard to explore fundamental concepts in genetics. While the film imagines resurrecting dinosaurs through ancient DNA, we break down the real science behind this film, clarifying what a genome is, how chromosomes organize DNA, and how genes function as trait-coding units with alleles as their variations. By separating cinematic fiction from reality, we can learn some genetics while uncovering what’s scientifically possible, and what is purely Hollywood fantasy.
