While seamen operated in a profession that transcended national boundaries, they were caught in a world sharply divided by ideologies and political blocs in the second half of the twentieth century. This talk focuses on two groups of mer...

G protein-coupled receptors (GPCRs) located at the cell surface bind extracellular ligands and convey intracellular signals via activation of heterotrimeric G proteins. Traditionally, G protein signaling was viewed to occur exclusively at this subcellular region followed by rapid desensitization facilitated by β-arrestin-mediated G protein uncoupling and receptor internalization. However, emergin...

Cryo-EM is a powerful technique that can visualize biomolecules in their near-native state, but suffers from the low contrast of biospecimens and their sensitivity to electron radiation. A phase plate addresses this challenge by shifting the phase of the unscattered beam by exactly 90 degrees relative to the scattered electrons, thereby enhancing image contrast. In this talk I will present the de...
