Episode 255: Inconceivable Slime Molds - Slime that Moves?!

OK, slime molds don't write. But amazing things have been written about them, allowing us to appreciate their wonder, explore societal ideas, and inspire future scientists. Dr. Lacy Johnson, from Rice University in Texas joins us to discuss why she chose to write a creative writing essay on slime molds and why she views creative writing as essential to science communication.   

How is intelligence defined? If you define it as learning and applying knowledge, then slime molds are intelligent. How did scientists determine this? How is a single celled organism with no brain or sensory organs able to experience its world and learn from it? Dr. Nirosha Murugan from Wilfrid Laurier University in Ontario Canada wanders with us to discuss research about slime mold intelligence, and maybe even a cyborg future. This may be Brandon's favorite episode ever! 

What is a slime mold? It is an inconceivable single celled organism that can weigh up to 40 pounds, think and learn, and crawl around the forest floor searching for food. How can a single celled organism be 44 pounds, learn, and move? Matt the Regular Slime Guy joins us to help introduce us to what a slime mold is and how such an inconceivable creature lives its life. 

Darren Vogt, Resource Management Division Director at 1854 Treaty Authority, joins us to discuss what the 1854 Treaty Authority is, how the Ojibwe views on partnership with the land impact how the 1854 Treaty Authority stewards the land and the living things on it, and how wild rice being viewed as a gift by the Ojibwe creates a different perspective on managing it than other organizations might have. He discusses how they engage in wild rice and the research they are doing.    

How do you restore wild rice to an area? Steven Hogg, Senior Manager of Wildlife at Three Rivers Park District, talks about the work done to bring back wild rice. From sourcing seeds, to distributing them, and making sure it grows Steven talks about the challenges, what he's learned, and how the restoration is going at Three Rivers. 

Wild rice can be found in every grocery store, but what is it? Is it a rice? A grain? Find out as we learn about this uniquely North American food that has been in Minnesota for at least 12,000 years. Ann Geisen from the Minnesota Department of Natural Resources wanders with us as we paddle through that rich history and context around wild rice in Minnesota.   

Dr. Adam Berland from Ball State University joins us to talk about research on why trees are important for people in an urban environment. He also talks to us about the surprising conclusions from his research in Minneapolis on how urban foresters can plant trees to prevent future large die offs from climate change and invasive species such as we've seen from Ash trees with Emerald Ash Borer, and Elm trees with Dutch Elm disease. He gives some advice on how you can choose trees that will help increase the resilience of trees to stress in the area. 

Laila Bacon and Makayla Freeman started working with Analyah Schlaeger do Santos when they were 14 years old. Seven years later they are still planting trees in Hennepin County were tree deserts exist, and teaching their community how to plant and care for the trees. Join us as they discuss why this work is important to them, the accomplishments and challenges they have faced over the last seven years, and how they keep hope alive despite the despair they sometimes feel trying to mitigate climate change. 

Trees provide health, economic, and many other benefits just by being present. However, some suburbs and urban areas in and around Minneapolis and Hennepin County are tree deserts. Analyah Schlaeger dos Santos, Environmental Justice Youth Director & Global Climate Justice Coordinator, MN Interfaith Power and Light, among many other things,. Joins us to talk about work she has done to increase tree cover in parts of Minneapolis and surrounding suburbs that had none, why that is important, and how it became a community effort.   

While connecting with fisher researchers Angela and Brandon were told over and over that there was one researcher they had to talk to. Dr. Roger Powell, Professor Emeritus at NC State University in North Carolina has been researching fishers for decades and is considered the expert on them. He shares his insights into fishers, how he raised fishers to learn more about them, and how they fit into, what he calls, a fitness landscape.
