Mansi Srivastava and I have edited a new book that’s packed with scientists’ stories about emerging model organisms. The book presents some interesting additions to the core set of model organisms, with contributions from people who have developed new model systems or advanced tools for emerging models. And it includes personal stories about how and why model systems were developed. The book isn’t comprehensive – we look forward to reading other scientists’ stories about these and other emerging models. But if you’re looking for 700+ pages of fascinating biology, we encourage you to take a look!
