Catalyst — Chemical Substances

Every episode asks one question: what does this molecule actually do in the world?

Hosted by Kaito. Short-form chemistry (3–5 minutes), organized across five lenses: Vital, Industrial, Medicinal, Toxic, and Cultural. From caffeine to PFAS to botulinum toxin — the chemistry around us is stranger and more consequential than most of us were taught.

New episodes weekly. No drama, no doom — just the molecules, honestly told.
