Signal Hill: Caterpillar Roadshow

A couple years ago, an entomologist named Martha Weiss got a letter from a little boy in Japan saying he wanted to replicate a famous study of hers. We covered that original study on Radiolab more than a decade ago in an episode called Goo and You – check it out here – and in addition to revealing some fascinating secrets of insect life, it also raises big questions about memory, permanence and transformation. The letter Martha received about building on this study set in motion a series of spectacular events that advance her original science and show how science works when a 12-year-old boy is the one doing it. Martha’s daughter, reporter Annie Rosenthal, captured all of it and turned it into a beautiful audio story called “Caterpillar Roadshow.” It was originally published in a brand new independent audio magazine called Signal Hill, which happens to have been created in part by two former Radiolab interns (Liza Yeager and Jackson Roach, both of whom worked on this piece), and we loved it, so we’re presenting an excerpt for you here.Special thanks to Annie Rosenthal, Liza Yeager, Jackson Roach, Leo Wong, Omar Etman, the whole team at Signal Hill, Carlos Morales, John Lill, Marfa Public Radio and Emma Garschagen.EPISODE CREDITS: Reported by - Annie RosenthalProduced by - Annie Rosenthalwith help from - Leo Wong and Omar EtmanSound design contributed by - Liza Yeager and Jackson RoachFact-checking by - Alan Deanand Edited by  - Liza Yeager and Jackson RoachEPISODE CITATIONS:Audio -  Listen to the original Radiolab episode, Goo and You, here (https://zpr.io/qh9xqpkXzk7j).Or the Signal Hill podcast here (https://zpr.io/CDfwyK7Zkrva).Guests - And if you want to learn more about Martha Weiss, and her work, head over here (https://zpr.io/aBw2YsqWB6NZ).Signup for our newsletter!!
