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.
In Contentious Meeting, SACGHS Tackles Gene-Association Patentability, Impact of Exclusive Licenses
Although SACGHS has yet to finalize its recommendations to exempt diagnostic developers from infringing on gene-association patents, last week's meeting ignited a debate on whether such a recommendation can be acted upon by the HHS Secretary, whether this would harm innovation, and whether the committee's conclusions about gene patents' deleterious impact on patient access was support by evidence.
