TL;DR: Gene networks involved in generating key differences between the queen and worker castes show signatures of increased methylation and suggest that ants and bees may have independently co-opted the same gene regulatory mechanisms for reproductive division of labor.
Abstract: We report the draft genome sequence of the red harvester ant, Pogonomyrmex barbatus. The genome was sequenced using 454 pyrosequencing, and the current assembly and annotation were completed in less than 1 y. Analyses of conserved gene groups (more than 1,200 manually annotated genes to date) suggest a high-quality assembly and annotation comparable to recently sequenced insect genomes using Sanger sequencing. The red harvester ant is a model for studying reproductive division of labor, phenotypic plasticity, and sociogenomics. Although the genome of P. barbatus is similar to other sequenced hymenopterans (Apis mellifera and Nasonia vitripennis) in GC content and compositional organization, and possesses a complete CpG methylation toolkit, its predicted genomic CpG content differs markedly from the other hymenopterans. Gene networks involved in generating key differences between the queen and worker castes (e.g., wings and ovaries) show signatures of increased methylation and suggest that ants and bees may have independently co-opted the same gene regulatory mechanisms for reproductive division of labor. Gene family expansions (e.g., 344 functional odorant receptors) and pseudogene accumulation in chemoreception and P450 genes compared with A. mellifera and N. vitripennis are consistent with major life-history changes during the adaptive radiation of Pogonomyrmex spp., perhaps in parallel with the development of the North American deserts.

TL;DR: The near-infrared spectrum of Triton reveals ices of nitrogen, methane, carbon monoxide, and carbon dioxide, of which nitrogen is the dominant component, which challenges existing models of methane and nitrogen photochemistry on Tritons.
Abstract: The near-infrared spectrum of Triton reveals ices of nitrogen, methane, carbon monoxide, and carbon dioxide, of which nitrogen is the dominant component. Carbon dioxide ice may be spatially segregated from the other more volatile ices, covering about 10 percent of Triton's surface. The absence of ices of other hydrocarbons and nitriles challenges existing models of methane and nitrogen photochemistry on Triton.

TL;DR: Testing the hypothesis that internalizing conventional ideas about femininity in two domains—inauthenticity in relationships and body objectification—is associated with diminished sexual health among adolescent girls revealed that inauthenticity inrelationship were associated with poorer sexual self-efficacy and sexualSelfefficacy, in turn, predicted less sexual experience and less use of protection.
Abstract: This study used a feminist developmental framework to test the hypothesis that internalizing conventional ideas about femininity in two domains—inauthenticity in relationships and body objectification—is associated with diminished sexual health among adolescent girls. In this study, sexual health was conceptualized as feelings of sexual self-efficacy (i.e., a girl's conviction that she can act upon her own sexual needs in a relationship) and protection behavior (i.e., from both STIs and unwanted pregnancy). A total of 116 girls (aged 16–19) completed measures of femininity ideology, sexual self-efficacy, sexual experiences, and protection behavior. Results revealed that inauthenticity in relationships and body objectification were associated with poorer sexual self-efficacy and sexual self-efficacy, in turn, predicted less sexual experience and less use of protection. Further, the two components of femininity ideology were associated with different forms of protection. The importance of a feminist developmental framework for identifying and understanding salient dimensions of sexual health for female adolescents is discussed.

TL;DR: In this paper, the authors examined the structure of the salinity field in northern San Francisco Bay and how it is affected by freshwater flow using 23 years of daily salinity data taken by the U.S. Bureau of Reclamation along the axis of the bay and found that the mean salinity distribution of the estuary is nearly self-similar with a salinity gradient in the center 70% of the region between the Golden Gate and X2 that is proportional to X−12.
Abstract: The structure of the salinity field in northern San Francisco Bay and how it is affected by freshwater flow are discussed. Two datasets are examined: the first is 23 years of daily salinity data taken by the U.S. Bureau of Reclamation along the axis of northern San Francisco Bay; the second is a set of salinity transects taken by the U.S. Geological Survey between 1988 and 1993. Central to this paper is a measure of salinity intrusion, X2: the distance from the Golden Gate Bridge to where the bottom salinity is 2 psu. Using X2 to scale distance, the authors find that for most flow conditions, the mean salinity distribution of the estuary is nearly self-similar with a salinity gradient in the center 70% of the region between the Golden Gate and X2 that is proportional to X−12. Analysis of covariability of Q and X2 showed a characteristic timescale of adjustment of the salinity field of approximately 2 weeks. The steady-state response deduced from the X2 time series implies that X2 is proportional ...

TL;DR: In this paper, the authors provide evidence as to the quality-of-life implications of the community computer network known as the Blacksburg Electronic Village (BEV), and the results of the longitudinal study indicate frequent and increasing use of the BEV and the Internet for local, social-capital-building activities.
Abstract: This article adds to the debate over whether easy access to the Internet is the only outcome of community computer network projects or if there are tangible impacts to these initiatives. Building from Putnam's links between quality of life, community involvement, and social capital, the authors provide evidence as to the quality-of-life implications of the community computer network known as the Blacksburg Electronic Village (BEV). The results of the longitudinal study indicate frequent and increasing use of the BEV and the Internet for local, social-capital-building activities. However, there is no trend toward an increase in community involvement or attachment except in a subset of the population that scores high on measures of preexisting community involvement. The results offer Putnam justification for his claims about the Internet's role in social capital formation.
