      • Insights into human genetic variation and population history from 929 diverse genomes

        Genomes from diverse human populations record human genetic diversity and illuminate the history of our species.

      • The genetic architecture of the human cerebral cortex

        Common genetic variation is associated with interindividual variation in the structure of the cortex of the human brain.

      • Structural basis of Gs and Gi recognition by the human glucagon receptor

        Structures of a G protein–coupled receptor bound to two different G proteins reveal molecular details that govern G protein selectivity.

COVER An iceberg from Antarctica drifts in the Southern Ocean. Mass loss from the Antarctic Ice Sheet, whether by iceberg calving or melting, will help determine the future of sea level in our warming climate. How the ice sheet changes over the coming decades to centuries will depend on its structure, dynamics, and interactions with the atmosphere and surrounding ocean. See page 1316.
