A new generation of radiotherapies for cancer, and why we sigh

First up on the podcast, Staff Writer Robert F. Service joins host Sarah Crespi to talk about a boom in nuclear medicine, from new and more powerful radioisotopes to improved precision in cancer cell targeting. Next on the show, we talk about why we sigh. Maria Clara Novaes-Silva, a doctoral student at ETH Zürich, discusses how deep breaths cause minute rearrangements at the special interface where air meets lung. The lung flexibility granted by these deeper inhalations suggest people on ventilators might have better lung health if they were served a larger draught of air from time to time.
