In a decades-long effort, researchers have discovered how to tweak the molecular pathways that turn heart muscle motors up or ...

We have used electron microscopy and single-particle image processing to study head conformation in myosin V molecules. We find that in the presence of ATP, many heads have a sharply angled ...
