About Jesse Noar



I'm a microbiology PhD from North Carolina State University who finds microbes continually fascinating. I'm working on ways to see just how good for us bacteria can be, and in order to share my enthusiasm for discoveries made by others or myself, I created BacterioFiles.

Back in early 2009 when science podcasts first caught my interest, I looked around to see if I could find any up-to-date podcasts that were focused on microbiology. There were a few, but they mostly seemed to focus on the negative aspects of bacteria or viruses that cause disease. I wanted news about how important bacteria and other microbes are, in our bodies, in the environment, and even in our technology, as well as how interesting and diverse they can be. So my path was clear: I had to fill the niche.

That path led to the creation of BacterioFiles, the podcast for microbe lovers, dedicated to promoting the exploration of the mostly-invisible world that is all around us.

Predatory bacteria have a particular protein that protects them from their own prey-damaging enzymes

Small Cells Stimulate Satiety - BacterioFiles 264

Written by

Proteins from gut bacteria seems to affect hunger and satiety in their (rodent) hosts.

Microscopic parasites of fish and worms actually came from jellyfish-like animals, after losing most of their genome.

Clostridium bacteria that infect potatoes can both kill competitors and tolerate oxygen, thanks to the pink compounds they produce.

Viruses domesticated by parasitoid wasps have transferred wasp genes to caterpillar victims, allowing them to survive deadly infections from other viruses! This means that Monarch butterflies are effectively naturally Genetically Modified Organisms (GMOs).

Bacteria in hydrothermal vents that feed their host tubeworms evacuate when their hosts perish.

In this episode Jesse Noar converses with Dr. Michael Smout about a liver fluke parasite that could help heal chronic wounds more quickly.

Bacterial toxins could be modified to deliver life-saving proteins into neurons.

Bacteria have repeatedly captured and used the tails of phages to fight each other.
