Why do jellyfish glow? How do fireflies light up the night? And what exactly is happening at the molecular level when organisms make their own light?

In this episode of Lauren and PJ Do Science, we kick off our glow-up era with Part 1 of a deep dive into bioluminescence — the chemistry, biology, and evolutionary “why” behind one of nature’s coolest party tricks. We talk about luciferins, luciferase, energy transfer, and why glowing can be a survival strategy rather than just a flex. We also discover that Lauren may or may not have a slight obsession with Nicolas Cage.

This is the first half of our bioluminescence series, setting the stage for how light-producing biology shows up in the ocean, on land, and in modern science and medicine.

✨ Bonus: Check out the companion playlist for this episode — songs that glow, shimmer, and scientifically radiate the right vibe while you listen or study.
