Challenges (ISSN 2078-1547) is a unique, international, scientific open access journal. It publishes scholarly content which is typically not publishable in traditional research journals, such as research proposals (funded and unfunded), registered reports (study protocols prior to experiments being conducted), research plans (e.g., a protocol for a systematic review, further research of a technology application, etc.), research or technology ideas, policy studies relating to science and scholarly research, open contests aimed at solving grand challenges, prize announcements, description of prototypes, calls for, or description of, international research collaborations or complementary support, etc.
Manuscripts submitted to Challenges must comply with the highest scientific standards and will be peer-reviewed before a decision regarding publication in the journal is made. For funded research proposals, the peer-review process will not be necessary and manuscripts will be published after copy-editing and with comments from the grant reviewers, if available. In addition, authors will benefit from discounts on publication charges if they subsequently submit a paper related to the research project to another MDPI journal.
