Have you ever heard that coffee and caffeine are bad for kids because it stunts their growth? Well an argument between Ryan and his wife lead him to look into this seemingly verifiable scientific fact and it turns out this super common knowledge idea is a myth. Made up for marketing purposes by C.W. Post to sell his coffee alternative product, and it worked even better than he could have ever expected. The scientific evidence directly counters this idea though. Ryan and Zach discuss how this myth took hold in the U.S. We discuss the neuroscience of caffeine and how it works to make you feel awake. Also, how does caffeine interact with an ADHD brain? Finally we move onto how to maximize the effects of caffeine and get the most out of the most commonly used psychoactive substance on the planet. If you want to have the most efficient coffee intake according to neuroscience, then follow this advice. The episode ends with a discussion on political violence in the news, then specifically the attempted shooting at the White House Correspondents Dinner. And a follow up of Ryan’s prediction from earlier in the year about the President’s apparent dementia and how it affected the events that unfolded at the dinner party.

The bigfoot cryptid monster makes for a really fun and enlightening example of how science is not supposed to work, despite what his proponents have to say about him. While cryptid monsters can be fun and whimsical, they and the search for them, a field known as cryptozoology, are also one of the most potent examples of pseudoscience. In this episode Zach and I explore the topic of cryptozoology, why it is a pseudoscience and what legitimate science actually looks like.

In this episode I explain dog genetics to my friend, comedian Zach Jobe. The story of how dogs became what they are today is a two stage process beginning with the ancient and gradual domestication of dogs from wolves and breeding based of jobs such as herding, hunting or guarding. Then modern dog breeding practices changed the landscape completely and rapidly resulting in some weird genetic quirks that give us the lovable little sweethearts that we know today.
