Sequencing and Analysis of the Hydra Genome
Chapman, Kirkness et al., Nature
An international research collaboration reports their sequencing and analysis of the Hydra magnipapillata genome, and compare it to the genomes of several other organisms. "The Hydra genome has been shaped by bursts of transposable element expansion, horizontal gene transfer, trans-splicing, and simplification of gene structure and gene content that parallel simplification of the Hydra life cycle," the authors write. They team suggests that comparisons of the Hydra genome to the reported sequences of other animals have helped them to elucidate the evolution of several of the organism's characteristics.
Venter, Scripps Researchers Offer DTC Genetics Recommendations
In an opinion article in Nature today, a group of J. Craig Venter Institute and Scripps Translational Science Institute researchers say they found discrepancies in results from two DTC genetics companies, prompting them to offer a set of recommendations to improve such tests.
