Today’s episode features a Spanish physics duo! First, we speak with Mariona Esquerda Ciutat, physicist and science educator, about her whiteboard physics videos in Catalan. Hear how important it is to spread scientific knowledge in every language, and then hear Mariona explain the colorful life cycle of stars in English (and a bit of Spanish). Afterward, Ricard Alert Zenon, Postdoctoral Fellow in the Lewis-Sigler Institute for Integrative Genomics, delivers us to the wonderful world of biophysics. It’s a field that describes everything from the mechanics of cell membranes to the elaborate transportation strategies of microscopic organisms.  For example, a thin film of bacteria covers everything around us, with a myriad of species coexisting in their 2D world. How do these separate cells communicate, and how can the whole film act as a single superorganism?
