More than 200 materials could be “altermagnets,” and the impact of odiferous pollutants on nocturnal plant-pollinator interactions   First up on the show this week, researchers investigate a new kind of magnetism. Freelance science journalist Zack Savitsky joins host Sarah Crespi to talk about recent evidence for “altermagnetism” in nature, which could enable new types of electronics.   Next on the show, producer Meagan Cantwell talks with Jeremy Chan, a postdoctoral researcher at the University of Naples Federico II, about how air pollution can interfere with pollinator activities—is the modern world too smelly for moths to do their work?   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Meagan Cantwell; Zack Savitsky   Episode page: https://www.science.org/doi/10.1126/science.zz09cbu
