The Journal of Internal Medicine has devoted its February issue to biogerontology, specifically the proceedings of the 4th Key Symposium on the Biology of Aging held last fall in Stockholm.

There are six long articles in the proceedings section, each devoted to a major topic within the field. JIM is regrettably not an open-access publication, but they have been kind enough to make three of the articles — on the subjects of evolution, mitochondria, and genomic approaches in the invertebrate model organisms — freely available to everyone.
