Have you ever noticed the colorful growths on trees and rocks but weren't sure what they were? Lichens are all around us yet often overlooked. They play important roles in ecosystems and can even indicate air quality. Many people don't fully understand these symbiotic organisms or appreciate their significance.
In this episode, you'll learn about the fascinating world of lichens from lichenologist Dr. Jessica Allen. We discuss what lichens are, their importance in nature, how they live, and how we can appreciate these miniature ecosystems all around us. You'll come away seeing lichens in a whole new light!
Topics covered in this episode:

Have you ever noticed little white fluffy spots or yellowish patches on your lettuce at the grocery store? This could be downy mildew, a microbe that infects lettuce and other leafy greens.
This microbe might not be well-known, but it's of great importance due to its effects on the agriculture industry and the food we buy. It poses a significant challenge for farmers by potentially wiping out entire crops. If we unknowingly purchase lettuce or herbs infected with downy mildew from the organic section, we might end up with unappealing produce.
Understanding downy mildew can help us make informed choices at the store and gain insight into the challenges faced by farmers in controlling this pathogen.
So, in this episode we'll learn about downy mildew from plant pathology researcher Dr. Kelsey Wood. She'll explain what this organism is, how to identify it, and the latest research aiming to control it in a more sustainable way. We'll also cover its life cycle, genetics, and impacts on agriculture. Tune in to discover this intriguing plant pathogen.

While many microbes bring benefits, pathogens are the focus when ensuring food safety. This episode dives into practical tips for enjoying chicken, whether you buy chicken or eggs from the store or raise your own chickens for eggs in your backyard.
Join food safety expert Dr. Andrea Etter as she shares insights into preventing foodborne illnesses caused by bacteria like Salmonella and Campylobacter. Dr. Etter is an assistant professor specializing in food microbiology and food safety at the University of Vermont. From her vast knowledge, you’ll learn how to prepare chicken at home safely and even keep your own backyard chickens.
By understanding basic food safety practices, we can protect ourselves and our loved ones while not forgetting the many positive roles of microbes in our lives.
Dr. Etter will equip you with strategies for safe chicken handling, from effective cooking techniques to proper backyard coop hygiene.
Join us as we explore food safety. I hope this empowers you to make informed choices for safe chicken handling.

Have you ever thought about the trillions of invisible, microscopic entities inhabiting your body right now? While much of the microbiome spotlight shines on bacteria, there's a hidden side to this story that many people overlook.
In this podcast episode, we discuss the lesser-known residents of our microbiome: viruses. These tiny but potent entities are fundamental players in our gut's ecosystem. And Michael Shamash, a microbiology researcher studying these viruses, shares all the profound roles they play in our gut and our overall health. After listening, you'll gain a newfound appreciation for these microscopic allies within you and how they can impact your well-being.

Are you curious about how microbes are involved in creating a more sustainable world? Those tiny, often-overlooked organisms hold a remarkable secret — the power to break down chemicals through biodegradation. Imagine a world where plastics and other challenging compounds, often seen as environmental villains, could be transformed into environmentally-friendly products.
In this episode, I chat with Dr. Jhonatan Hernandez Valdes to discuss how these microbes are revolutionizing our approach to sustainability. He shares about his role as a microbiologist at Nouryon, investigating and understanding how microbes degrade chemicals in the environment. Ultimately, his research aims to help in developing more environmentally friendly products.
Tune in if you want to explore how we can work with microbes to leverage their transformative powers to pursue a greener, cleaner world.
