GW150914: First results from the search for binary black hole coalescence with Advanced LIGO

Abstract: On September 14, 2015, at 09∶50:45 UTC the two detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO) simultaneously observed the binary black hole merger GW150914. We report the results of a matched-filter search using relativistic models of compact-object binaries that recovered GW150914 as the most significant event during the coincident observations between the two LIGO detectors from September 12 to October 20, 2015 GW150914 was observed with a matched-filter signal-to-noise ratio of 24 and a false alarm rate estimated to be less than 1 event per 203000 years, equivalent to a significance greater than 5.1 σ.

Gene Flow and Isolation among Populations of Marine Animals

Abstract: Successful dispersal between populations leaves a genetic wake that can reveal historical and contemporary patterns of connectivity. Genetic studies of differentiation in the sea suggest the role of larval dispersal is often tempered by adult ecology, that changes in differentiation with geographic distance are limited by disequilibrium between drift and migration, and that phylogeographic breaks reflect shared barriers to movement in the present more than common historical divisions. Recurring complications include the presence of cryptic species, selection on markers, and a failure to account for differences in heterozygosity among markers and species. A better understanding of effective population sizes is needed. Studies that infer parentage or kinship and coalescent analyses employing more markers are both likely to spur progress, with analyses based on linkage disequilibrium potentially bridging results from these studies and reconciling patterns that vary at ecological and evolutionary timescales.

Systemic determinants of international news coverage: a comparison of 38 countries

Abstract: This study investigates the influence of systemic determinants on international news coverage in 38 countries. Systemic factors include traits of nations, magnitude of interaction and relatedness between nations, and logistics of news gathering. Multiple regression is implemented to assess 9 systemic determinants in each individual country. Findings indicate that the U.S. was the most covered country in the world. In spite of some variation, trade volume and presence of international news agencies were found to be the 2 primary predictors of the amount of news coverage. The study concludes that the prediction framework of international news coverage has probably altered in the post-Cold War epoch and, therefore, that the relevant problems need to be revisited.
