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.
DNA Barcoding Suggests Migratory Canada Geese Caused Hudson River Crash
June 08, 2009
Researchers from the Smithsonian Institution and the US Department of Agriculture used DNA barcoding and isotope ratio mass spectrometry to determine that migratory Canada geese were the birds that brought down US Airways Flight 1549 this past January.
