BIO-Complexity has added a new category of peer-reviewed papers, under the heading Critical Focus. The description for authors is:

Critical Focus papers provide peer-reviewed critical analysis that is narrower than a Critical Review, focusing either on a more narrow subject or on a smaller part of the existing literature. The focus may be one or a few closely related papers published elsewhere that fall within BIO-Complexity's stated scope. This category allows for more extended technical analyses of a single study than would be appropriate for a Critical Review, as well as shorter treatments of more specific subjects than would justify a Critical Review.
