Longer looks: A surgeon examines his professional development

I've been a surgeon for eight years. For the past couple of them, my performance in the operating room has reached a plateau. I'd like to think it's a good thing-;I've arrived at my professional peak. But mainly it seems as if I've just stopped getting better. During the first two or three years in practice, your skills seem to improve almost daily. It's not about hand-eye coördination-;you have that down halfway through your residency.

Researchers describe new function of HCN channels in the heart

The heartbeat is the result of rhythmic contractions of the heart muscle, which are in turn regulated by electrical signals called action potentials. Action potentials result from the controlled flow of ions into heart muscle cells (depolarization) through channels in their membranes, and are followed by a compensating reverse ion current (repolarization), which restores the original state. If the duration of the repolarization phase is not just right, the risk of ventricular arrhythmia and sudden cardiac death increases significantly.
