Nature Video: Bench or Bedside? With Ferid Murad

Camelia-Lucia Cimpianu 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 a gas called nitric oxide (NO) acts as a signalling molecule in the cardiovascular system. It turns out that NO plays a role in many diseases — and possibly in the head trauma cases that Camelia studies.
