Chemistry For Your Life

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.

Glass. The more you look at it, the more clear it becomes that it holds some serious mysteries. So what really is glass? Is it a liquid? How is it different from typical solids? Does it flow and ooze over time? Is that why old windows are thicker at the bottom? Let's find out!
