There are very few remaining locations on Earth that are untouched by humans, and those that do remain are in very extreme environments that are difficult to access.  However, accessing and studying life in these extreme environments can provide unique insights to the biology of life. Understanding how simple organisms adapt and survive in seemingly unlivable conditions is a unique field of study with the potential to inform and affect the human condition.  

We’re joined in this episode by Dr. Brandi Kiel Reese and Lydia Hayes-Guastella from the Dauphin Island Sea Lab at the University of South Alabama. They are both geomicrobiologists that study microbial life in extreme environments like the Mariana Trench and Antarctica.  They do an excellent job of painting a picture of how extreme conditions are in these environments and how they manage to collect and preserve samples from such harsh conditions. We learn about the various methods they use to analyze the microbial samples they collect, including the use of digital PCR (dPCR) to detect and quantify transcripts that would otherwise not be detectable given how few cells they’re able to collect.   

Brandi and Lydia also share their unpredictable career path journeys, while sharing some insights and learnings from their respective experiences. We learn what they each love about their work and what qualities is takes to be successful at what they do. Once again, we’re reminded of what a small world it is, especially when you’re in a specialty field such as geomicrobiology of extreme environments.
