The International Society for Computational Biology (ISCB) and WikiProject Computational Biology announce the 8th ISCB Wikipedia Competition: the competition aims to improve the coverage on Wikipedia of any aspect of computational biology. A key component of the ISCB's mission to further the scientific understanding of living systems through computation is to communicate this knowledge to the public at large. Wikipedia has become an important way to communicate all types of science to the public and the ISCB aims to further its mission by increasing the quality of Wikipedia coverage of computational biology, and by improving accessibility to this information via Wikipedia. The competition is open to students and trainees at any level either as individuals or as groups.
