Chemistry For Your Life

Rebroadcast #068

This week we issue a correction, joining other science publications issuing the same correction. That's kind of an obvious answer to the question of "Is science always right?" So in this episode we explore that question, as well as what happens when science isn't right. And why that's NOT a bad thing.

Can cooking pasta, rice, or bread, and then cooling it down, actually make it healthier? Could yesterday’s leftovers affect your blood sugar differently than a freshly cooked meal, or is this just another nutrition “hack” invented by the internet? Melissa and Jam investigate starch, glucose, insulin, digestion, crystallization, and the surprising chemistry that happens while your food sits in the fridge. Plus, the whole thing somehow turns into a Lord of the Rings battle involving glucose, hobbits, and ents, because of course it does.

What’s actually flowing through the “natural gas” pipes connected to your home—and did we get something wrong in our air-conditioning series? Which careers can an organic chemistry student pursue, how do topical pain-relief gels work, and what could make a successful HIV medication suddenly stop working? Melissa and Jam answer listener questions, revisit past episodes, correct the record, and stumble into a genuinely fascinating pharmaceutical mystery. Plus, could more chemistry history and chemistry-education stories be coming to the podcast?

Can shining a red light on your face really improve acne, wrinkles, inflammation, or wound healing, or is red light therapy just an expensive skincare scam involving a slightly alarming mask? How could ordinary visible light affect cells beneath your skin, and should you trust the products filling your social media feed? Melissa and Jam investigate photobiomodulation, mitochondria, collagen, blue light, FDA clearance, and the research behind this increasingly popular wellness trend. The answer is more scientifically interesting, and more complicated, than either of them expected.
