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.
Study Examines Link Between Industry Support and Research Integrity at US Medical Schools
June 03, 2009
Researchers at US medical schools who rely heavily on industry support are more likely to have been pressured by sponsors to act unethically and to have first-hand knowledge of integrity breaches at their institutions, according to a study from the University of Virginia School of Medicine.
