Brainy Stuff Starts at 22:00 and Behind the Redwood Curtain begins at 34:07
Margaret tells what she's been learning from Kristen Omdahl's Seamless Crochet Shawl where she tested out the Ninja Star Pattern with the AllHemp6 DK yarn.   She likes the pattern and the yarn but not with each other. 
Catherine talks about her progress on her projects:   Meadowlark Shibori Jacket by Gina Wilde and Clapo-Ktus by Loredana Gianferri and Some Pig washcloth by Eimly Guise
In Part I of why we put down one project and start the other in the Brainy Part, Margaret talks about Novelty and how it impacts our brain.   Then Catherine talks about the Godwit bird and the Zen Center in Arcata. 
Finally Margaret suggests trying different yarns and being aware that you might to use different tension and even different tensioning hand postures.
