Allan Hall is the lead distiller at Ranger Creek Brewing & Distilling, a “brewstillery” located in San Antonio that makes handcrafted beer and whiskey.


Beer brewing is applied microbiology utilizing the fungus Saccharomyces cerevisiae to ferment sugars that produce alcohol. Allan talks about the history of brewing and fermentation, the challenges of being an independent craft brewery, the science behind distilling whiskey, beer brewing around the world, and finding his love for science on the big island of Hawaii.


The MicroCase for listeners to solve is about Corky Kettle, a volunteer at a wildlife rehabilitation center with a soft spot for injured animals, who gets sick after rescuing a fox by the side of the road.

(Blood, That Is) and Transmit Diseases, Too!  Dr. Mary Ann McDowell is an Associate Professor at the University of Notre Dame. Dr. Joao Pedra is an Associate Professor at the University of Maryland School of Medicine.

McDowell studies the parasitic disease Leishmaniasis, which is transmitted tomcdowellhumans through the bite of a sandfly. Pedra studies Lyme disease and Anaplasmosis, which are bacterial diseases that are transmitted to humans through the bite of a tick. The sandfly and tick vectors play an essential role in the lifecycle of these human pathogens, and both McDowell’s and Pedra’s research is investigating the interaction of these pathogens with their vectors. A better understanding of vector biology may lead to novel means to control these diseases.

Drs. McDowell and Pedra discuss the possibility of controlling vector-borne disease by vaccines that target Pedra Joaopathogen transmission, the impact of global warming on vector-borne disease, and how teachers play an important role in inspiring the next generation of scientists.

The MicroCase for listeners to solve is about Adriana Wellington, a waitress at the Hitching Post who gets a mysterious disease while fulfilling her lifelong dream to see gorillas in the wild.
