Hidden Science Stories

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 @zhjobeConcept: 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.Tools: DaVinci Resolve, GIMPIntro music by Maksym Malko from Pixabay (pixabay.com/music/upbeat-podcast-interview-music-254186/)Podcast streams:redcircle.com/shows/04ecc7a3-3383-4ca0-bff3-c55d04100ed5podcasts.apple.com/us/podcast/hidden-science-stories/id1874450380open.spotify.com/show/50xaIb6jjmSJv7georpfVt?si=16e6c0e030414593music.amazon.com/podcasts/b0415a99-f209-4c66-80c5-d8eb2b490811/hidden-science-stories---Citations:vonHoldt et al.

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 @zhjobeConcept: 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.Tools: DaVinci Resolve, GIMPMusic by Maksym Malko from Pixabay (pixabay.com/music/upbeat-podcast-interview-music-254186/)———0:00 Let me tell you about my grandmother3:15 The different types of dementia22:23 A surprising connection to dementia27:06 Annual predictions 202627:55 Prediction 2: DJT has end-stage dementia36:01 Prediction 2: the AI bubble will burst38:22 Prediction 3: DONUT labs will be revealed a fraud57:27 Moonshot prediction: Betelgeuse will go Supernova63:41 OutroSupport this podcast at — https://redcircle.com/hidden-science-stories/donations

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.Open data fuels open science.———Created by: Ryan Pevey at evolio.org and Zach Jobe @zhjobeSupport my work and keep it sustainable: ko-fi.com/evolioConcept: A funny science and comedy story about how a well meaning peanut avoidance recommendation helped spike peanut allergies, and how evidence-based medicine helped bring them back down.Tools: DaVinci Resolve, GIMPMusic by Maksym Malko from Pixabay (pixabay.com/music/upbeat-podcast-interview-music-254186/)———Citations:Du Toit G, et al.
