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.
Fear of Losing Insurance Deters Genetic Testing for Bowel Cancer, Aussie Study Finds
The results from the Australian study may have implications for US consumers, since similar to Australia, US law bars health insurers from discriminating based on genetic information, but not companies providing life and disability insurance.
