The clustering of ryanodine receptors (RyR2) into functional Ca2+ release units is central to current models for cardiac excitation-contraction (E-C) coupling. Using immunolabeling and confocal microscopy, we have analyzed the distribution of RyR2 clusters in rat and ventricular atrial myocytes. The resolution of the three-dimensional structure was improved(More)
Craters can create windows into subsurface geology. Hydrothermal alteration products that correlate with ejecta from small craters (<100 m deep) can flag possible near-surface hydrothermal activity. A region with such activity is a highly prized target for Mars exploration. Here we describe an airborne (satellite analog) study that identified mineral(More)
STOCK DEFINITION AND GEOGRAPHIC RANGE Steller sea lions range along the North Pacific Rim from northern Japan to California (Loughlin et al. 1984), with centers of abundance and distribution in the Gulf of Alaska and Aleutian Islands, respectively. The species is not known to migrate, but individuals disperse widely outside of the breeding season (late(More)
