Science: The Wellcome Trust, a London-based charity that is one of the largest nongovernmental sources of funding for biomedical research, is launching an open-access online journal this fall. Wellcome Open Research will feature the work of researchers who are funded by Wellcome Trust grants, and the charity will also cover publishing costs for the authors. This will be the second time the company has been involved in an open-access journal: In 2012 it partnered with the Howard Hughes Medical Institute in Chevy Chase, Maryland, and Germany’s Max Planck Society to launch eLife. Wellcome Open Research will function more like the preprint server arXiv than a traditional journal, with authors encouraged to post anything from a full paper to just a data set. Following publication, a publicly selected group of peer reviewers will evaluate and comment on the work. The site will be managed by Science Navigation Group’s F1000 publishing service.
