clock | November 17, 2009Article-Level Metrics and the Evolution of Scientific Impact:
Formally published papers that have been through a traditional prepublication peer review process remain the most important means of communicating science today. Researchers depend on them to learn about the latest advances in their fields and to report their own findings. The intentions of traditional peer review are certainly noble: to ensure methodological integrity and to comment on potential significance of experimental studies through examination by a panel of objective, expert colleagues. In principle, this system enables…

The Gp-9 gene in fire ants represents an important model system for studying the evolution of social organization in insects as well as a rich source of information relevant to other major evolutionary topics. An important feature of this system is that polymorphism in social organization is completely associated with allelic variation at Gp-9, such that single-queen colonies (monogyne form) include only inhabitants bearing B-like alleles while multiple-queen colonies (polygyne form)…

clock | October 20, 2009Five Years of Access and Activism:
In April 2009, we marked the five year anniversary of PLoS Medicine's first call for papers with an editorial titled "A Medical Journal for the World's Health Priorities" [1]. The editorial was a renewed and revitalized call for papers, announcing a "refocusing of the journal's priorities." Going forward, we said, we would prioritize papers addressing those diseases with the greatest global burden. We would also aim to be as broad a journal as possible, publishing papers that explored not just biological causes of illness, but also social, environmental, and…
