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.
Task Force Advises Making Gene Patents Exempt from Infringement
The SACGHS task force has suggested that genetic testing patents are not necessary for innovation and may, in some cases, block patient access. However, the recommendations are not final and are being discussed at a meeting in Washington, DC, this week.
