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.
HHS Advisory Committee Recommends Creating Mandatory Genetic Test Registry
The HHS Secretary’s Advisory Committee for Genetics, Health, and Society said that a “mandatory, publicly available, web-based registry … would offer the best approach to address the information gaps” regarding lab-developed genetic tests. But it stressed that “unresolved issues, including practical and legal questions,” must be answered before the government can decide “how and where to implement the registry.”
