Camelia-Lucia Cimpianu, an early-career scientist who attended the Lindau Nobel Laureate Meeting this summer in Germany, is trying to decide between a career as a researcher or a practising doctor.

In this film, she seeks advice from Nobel Laureate Ferid Murad who faced the same dilemma as a medical student in the 1960s. Murad chose the bench, and he subsequently discovered that nitric oxide acts as a signalling molecule in the cardiovascular system. It turns out that nitric oxide plays a role in many diseases—and possibly in the head trauma cases that Camelia studies.
