005 - Is caffeine bad for kids?

Support my work and keep it sustainable: ko-fi.com/evolio 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. --- Created by: Ryan Pevey at evolio.org and Zach Jobe @zhjobe Concept: A science and comedy conversation about caffeine, whether it’s bad for kids, how does it work on your brain and ADHD.

004 - Cryptozoology vs. Discovery Ecology and eDNA

Support my work and keep it sustainable: ko-fi.com/evolio 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. --- Created by: Ryan Pevey at evolio.org and Zach Jobe @zhjobe Concept: A science and comedy conversation about what philosophical bullshit is and how to detectit.

003 - Dog Genetics, Domestication and Breeding

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. --- Created by: Ryan Pevey at evolio.org and Zach Jobe @zhjobe Concept: A science and comedy converstion about dementia and how it impacts people and society, as well as bold predictions of event that may or may not happen this year, based on scientific skepticism.

002 - Dementia and 2026 Annual Predictions

In this episode I explain dementia to my friend, comedian Zach Jobe. Starting with a personal story about my grandmother, we explore what dementia actually is, the different types of dementia, and how they present for patients and caregivers. We cover the latest research and why recognizing cognitive decline matters more than ever. Following that we make predictions for 2026, using only our scientific knowledge and critical thinking skills. ——— Created by: Ryan Pevey at evolio.org and Zach Jobe @zhjobe Concept: A science and comedy converstion about dementia and how it impacts people and society, as well as bold predictions of event that may or may not happen this year, based on scientific skepticism.

001 - How NOT to give your kids peanut allergies

In this episode I explain peanut allergies to my friend, comedian Zach Jobe. Peanut allergy rates tripled over the first decade of this century, so we cover the evidence showing why, and how they were successfully brought back down to historical levels using the process of science and evidence based healthcare policy.
