Biology Direct will serve the life science research community as an open access, peer-reviewed online journal encompassing the full spectrum of biological science, and will make all research articles available free of charge on the website immediately on publication. Biology Direct will publish original research articles, hypotheses, and reviews from the full spectrum of biology; the first subject areas to be launched will be Genomics, Bioinformatics and Systems Biology and further subject areas will be launched from time to time until the full spectrum of biology is covered. Subjects covered will include any aspect of molecular, cellular, organismal or population biology, as well as methods, theoretical and computational biology, comparative biology, and evolution. Biology Direct considers the following types of articles: a) Research: reports of data from original research, b) Reviews: comprehensive, authoritative, descriptions of any subject within the scope of the journal. These articles are usually written by opinion leaders that have been invited by the Editorial Board, and c) Hypotheses: short articles presenting an untested original hypothesis backed solely by previously published results rather than any new evidence. This has been added to Biological Informatics Subject Tracer™ Information Blog.
