Fireflies’ magical blinking lights are tiny beacons in the warm dark night. Who can resist catching one? Not scientists.Because their light comes from bodily chemicals, fireflies’ power of illumination has long been used as a tool in medical research. And that has driven scientists to investigate the inner workings of the blinking beetle itself. Researchers have recently discovered that fireflies’ glowing lanterns are only one of the ways they communicate.Host Ira Flatow talks with entomologist Sarah Lower and biochemist Stephen Miller about the latest advances in firefly science.Guests: Dr. Sarah Lower is an associate professor of biology at Bucknell University where she studies fireflies.Dr. Stephen Miller is a professor of biochemistry and molecular biotechnology at the UMass Chan Medical School.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Folge vom 18.08.2025How Agatha Christie Used Chemistry To Kill (In Books)Did you know that murder mystery writer Agatha Christie had a background in chemistry? In about half of her stories, the murder is committed using poison—something she was very, very familiar with. She had even trained in apothecaries to mix prescriptions by hand before she became a novelist. Chemist-turned-author Kathryn Harkup wrote about them in her new book, V is for Venom: Agatha Christie’s Chemicals of Death. Harkup talks with Host Flora Lichtman about the science of poisons, why they’re so popular in whodunnits, and how to get away with murder (in fiction writing, of course).Guest: Kathryn Harkup is a former chemist and author of V is for Venom: Agatha Christie’s Chemicals of Death.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
