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.
Myriad Defends Policy of Urging Docs to Genetically Counsel BRACAnalysis Customers
Responding to an HHS committee's request for comment on its educational and marketing practices, Myriad maintained that urging doctors to conduct genetic counseling in house instead of referring patients to a genetic counselor is legally sound, follows professional medical societies' standards, and accommodates the shortage of cancer genetics professionals.
