This week on the io9 show, we explore the Lost City of Z in Brazil, and the ancient city of Catalhoyuk in Turkey! Genetic engineer and How to Defeat Your Own Clone author Terry Johnson shows us how fluids like corn syrup have memory thanks to laminar flow! And finally, help us find a mysterious 1980s novel about a faerie orphan!
