#042 Rebroadcast What's that smell? Is it us? Is it you? We hope it's neither, thanks to deodorants and antiperspirants. This week, Melissa and Jam delve into the chemistry of this everyday important substance. What are the differences between deodorant and antiperspirant? How do they work in the first place? Does one work better? Is one better for us? Be kind to one another, wear deodorant.

Birds fly all the time. We see it constantly. But how does it actually work? Is it just "Bernoulli’s" principle? Is the air pushing up? Are the wings pushing down? And what’s happening at the molecular level when a bird takes off? Let’s talk about feathers, airflow, collisions between air molecules, and why the way flight is usually explained might not actually be the whole story.

A kid’s question sparks the episode. 01:00 — “Isn’t this physics?” Why a chemistry podcast is talking about aerodynamics. 02:00 — A disclaimer about flight explanations Melissa explains why common explanations of bird flight can be misleading. 04:00 — The weird analogy that starts it all What does oobleck (cornstarch and water) have to do with bird wings? 06:00 — Air isn’t nothing Thinking about air as billions of tiny molecules interacting with wings. 09:00 — The classic explanation of lift Bernoulli’s principle and why it’s often used to explain flight. 13:00 — Why that explanation isn’t the whole story What’s missing from the “air moves faster over the top” idea. 18:00 — Collisions at the molecular level What air molecules are actually doing when a wing moves through them. 22:00 — Pushing air downward Why deflecting air matters for creating lift. 26:00 — Wing shape and angle How airfoil shape and angle of attack change the behavior of airflow. 30:00 — Flapping vs gliding Why bird flight isn’t the same as airplane flight. 34:00 — Turbulence and airflow patterns What’s happening behind the wing as the bird moves through the air. 37:00 — Bringing chemistry into the picture How thinking about molecular motion helps make sense of the physics. 39:00 — Final recap So… what actually keeps birds in the air?   Support this podcast on Patreon Buy Podcast Merch and Apparel Check out our website at chemforyourlife.com Watch our episodes on YouTube Find us on Instagram, Twitter, and Facebook @ChemForYourLife References from the Episode: Thanks to our monthly supporters Amanda Raymond Emily Morrison Kyle McCray Justine Emily Hardy Ash Vince W Julie S.

In this bonus episode, we host a rematch of our game “Fun Fact or Fake Factoid” with Claire and Jam, using stricter rules: each claim must be entirely true or false as worded, and the winner earns a treat. We test statements about pregnancy-related brain changes, koala fingerprints, bird body temperature, whether every fig contains a dead wasp, how egg markings form, woodpecker tongues wrapping around their skulls, unique parrot pigments, bald eagles’ ability to take off from the ground, black bear maternal instinct, and whether red bird color is structural rather than pigment-based.

MRIs are loud. They’re huge. They’re magnetic. But what are they actually doing? This week, we bring Claire back to help us connect the dots between NMR (yes, organic chem flashbacks) and MRI. How does a technique built on tiny hydrogen protons turn into a 3D image of your brain? How can it tell the difference between tissue and fluid? Why can’t you bring metal anywhere near the machine? We ask: • What are your protons doing inside an MRI? • How does “magnetic resonance” become an image? • Why does oxygenated blood matter? • And how did anyone figure this out in the first place? If you’ve ever had an MRI, or just wondered how we can see inside the body without radiation or surgery, this episode pulls back the curtain. Listen in and rethink what’s happening inside that giant magnet. 00:00 MRI Episode Kickoff 01:11 Meet Claire Again 02:27 PhD Candidate Explained 03:44 NMR Basics Begin 04:33 Protons And Magnets 06:46 RF Pulse And Signal 11:16 Hydrogen Everywhere 13:35 Reading NMR Peaks 16:02 Matrix And Practice 18:31 Jam Summarizes NMR 20:44 Why MRI Not NMR 22:45 Spin And Isotopes 29:02 MRI Uses Body Water 30:37 Tissue Contrast And T1 33:38 Resolution Limits 34:25 MRI Resolution Limits 35:34 From NMR to Images 36:50 K Space and Gradients 41:30 Voxels and 3D Views 44:05 Contrast and Clinical Uses 49:47 Research Possibilities 51:11 Functional MRI Explained 56:14 MRI Safety and Magnet Strength 58:00 Helium and Heavy Machines 01:02:43 Science Boundaries and Wrap Up   Support this podcast on Patreon Buy Podcast Merch and Apparel Check out our website at chemforyourlife.com Watch our episodes on YouTube Find us on Instagram, Twitter, and Facebook @ChemForYourLife References from the Episode: Thanks to our monthly supporters Amanda Raymond Emily Morrison Kyle McCray Justine Emily Hardy Ash Vince W Julie S.
