Ask a Chemist: Is Silicone actually safe? (and other questions)

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.
