Recent Nature issue on depression

Nature recently devoted an issue to depression, and some of the articles (commentary rather than research reports) are available for free download as PDFs. Start with this infographic about depression worldwide and scroll down to the list of other titles at the bottom. All of the titles from 2014 and two from 2013 are currently available at no charge. Lots of interesting stuff there, including a comparison of research on cancer and on depression and a discussion of current ideas on what makes cognitive behavioral therapy work.
