A Model of Genetic Variation in Human Social Network

submitted by: dougramsey
Social networks influence the evolution of cooperation and they exhibit strikingly systematic patterns across a wide range of human contexts. Both of these facts suggest that variation in the topological attributes of human social networks might have a genetic basis. While genetic variation accounts for a significant portion of the variation in many complex social behaviors, the heritability of egocentric social network attributes is unknown. Here we show that three of these attributes...

Integrated Information System for Genomic and Metagenomic Data Analysis at National Center for Biotechnology Information (NCBI)

submitted by: dougramsey
Recent advances in biotechnology and bioinformatics has provided a flood of genomic data and tremendous growth in the number of associated data sets. Sequencing projects now include draft assemblies, complete genomes, comparative genomics, and metagenomics where genetic material is sequenced directly from environmental samples. The NCBI provides integrated systems for data storage, retrieval, and analysis. GenBank, an archival database of DNA sequences, contains consensus sequences assembled...
