PLoS now has blogs. The announcement accentuates that they have an equal representation of scientists and science journalists.
Neuroanthropology, authored by Daniel Lende and Greg Downey, will be of interest to many of my readers. John Rennie also has a "plog" as they're calling them, "The Gleaming Retort". "Speakeasy Science", by University of Wisconsin journalism professor Deborah Blum, has made the jump to PLoS as well.
