Mark and Toddcast

We're back with a super-sized episode as we catch up with two weeks' worth of news, more Chinese presents for Todd's birthday, and Mark's recent trip. And that's before we get to the current state of 3D printing! In the news: Polar Vortex kills stinkbugs (hopefully), the Navy's room-temperature superconductor, YouTube demonetizes anti-vaxx channels, humpback whale in the Amazon jungle, a llama on the MAX, the science of "Dad Jokes," and the world's quietest room will drive you crazy in just 45 minutes. Enjoy!
