What happens when some listeners challenge one of our past episodes? This week we’re revisiting our silicone episodes after several listeners pointed us toward new research. Along the way we answer questions about mosquito wristbands, waterproof mascara, stubborn adhesives, and whether amino acids may have formed on the early Earth after all. It’s an Ask a Chemist episode full of updates, follow-ups, and a reminder that science is always a work in progress.

What if chemistry classes were organized around real-world problems instead of chapters in a textbook?In this bonus BCCE Community Conversation preview, Melissa talks with Vicente Talanquer about helping students think like chemists rather than simply memorize chemistry. They explore why authentic, real-world problems can transform learning, how instructors can make meaningful changes without rewriting an entire course, and why teaching chemistry is about developing a way of thinking—not just delivering content.

There are a lot more ways to reveal a fingerprint than the black powder you see on TV.In this second part of our forensic chemistry series with Nicki Stewart, we explore the surprising chemistry behind fingerprints. From powders and iodine vapor to super glue fumes and chemical reactions, we break down how forensic scientists reveal invisible fingerprints—and why choosing the right method depends entirely on the surface, the chemistry, and the evidence they’re trying to preserve.
