As a neuroscientist: lots of my study is improved by the understanding of physics. Electrophysiology is a classical example of folks studying the physics-only aspect of neurobiology. But, more crucially than that, our brain cells are ion-specific. Some times they let in only sodium, some times only potassium, and some times only calcium. Understanding how biology maintains specificity at the single atom level, while letting in millions of those atoms in at the same time is a purely physical riddle. We have some answers to it, if I've sparked your curiosity. ;)
