The ochre seastar (Pisaster ochraceus) is a common inhabitant of rocky intertidal shores from Alaska to Baja. It is the quintessential “keystone” predator, and it has been shown to have an inordinately large influence on the diversity and structure of rocky shore communities. For this reason, it has been a focal species in the monitoring programs of the Channel Islands National Park, the Channe...

INTRODUCTION Kawasaki disease is an idiopathic acute systemic vasculitis of childhood. Although it simulates the clinical features of many infectious diseases, an infectious etiology has not been established. This is the first reported case of Kawasaki disease following Rocky Mountain spotted fever. CASE PRESENTATION We report the case of a 4-year-old girl who presented with fever and petechi...

In highly urbanized regions, rocky intertidal habitats attract a large number of visitors for recreation, education, and subsistence harvesting. The collecting, trampling, and handling activities of visitors can have detrimental impacts on intertidal flora and fauna, including reduced abundances and biodiversity and alteration of community structure and function. Despite the large human populat...

The Kepler mission, combined with ground-based radial velocity (RV) follow-up and dynamical analyses of transit timing variations, has revolutionized the observational constraints on sub-Neptune-sized planet compositions. The results of an extensive Kepler follow-up program including multiple Doppler measurements for 22 planet-hosting stars more than doubles the population of sub-Neptune-sized ...

Five dose reconstruction projects focusing on historical public exposures from U.S. government nuclear facilities have been completed in the last 12 y (Fernald, Hanford, Nevada Test Site, Oak Ridge, Rocky Flats). Using information available in published reports, doses and excess health risks of the most serious contaminants in each study are compared for representative maximally and typically e...

kids.frontiersin.org Of all the questions that science might hope to answer, few excite people more than “is there life on worlds other than our Earth, and, if so, do any alien creatures possess intelligence similar to that of human beings?” But how can we find rocky Earth-like worlds that orbit around stars other than our Sun? Remarkably, the first astronomical evidence that such worlds exist ...

The detailed technological analysis of the youngest Howiesons Poort occupation in Sibudu Cave, layer Grey Rocky, has shown the importance of blade production (with different knapping methods involved), but also of flaking methods in coarse grained rock types. Moreover, new strategies of bifacial production and microlithism were important. Grey Rocky lithic technology shows a really versatile ex...
