Drug peptides defy shape rules, activating receptors without full spiral form

When many of us think about how drugs work in the body, we may first think about how a drug gets into the body, such as a pill versus an injection. In the Gellman Group at the UW–Madison Department of ...

Liquid ripples rewrite 130-year-old biological classic: New reflections on the lock-and-key model

This April, when the spring breeze carried the formal acceptance notice of our paper by the Journal of the American Chemical Society to my desk, my thoughts instantly drifted back to the late Phil ...
