"Nature Precedings is a place for researchers to share pre-publication research, unpublished manuscripts, presentations, posters, white papers, technical papers, supplementary findings, and other scientific documents. Submissions are screened by our professional curation team for relevance and quality, but are not subjected to peer review."
It seems you can just submit a paper and then people can vote on it, and discuss it. Most of the popular papers are about H5N1. I can see the usefulness of rapidly sharing some information, such as polymorphisms and possible antigens. Information sharing is key if an epidemic is ever to occur. And this type of information can probably get away with not having been peer reviewed. But when I perused the cancer section I noticed some strange papers. Take this one for example "metastasis as a faulty recapitulation of ontogeny". It reads more like an OP-ED than a review or paper. The premise is that transforming somatic cells with oncogene is like bringing back the cell to its original progenitor-like state. For example some lung cancer cells look like the embryonic cells that give rise to the alveolar epithelium. Well nothing new here. He author argues that these "progenitor-like" cells will behave like their embryonic counterparts and migrate in a similar fashion. Well nothing outlandish here either. He also argues that some of the metastases may implant in different organs and assume the identity of that organ and maybe remain unnoticed. While this is all somewhat interesting I doubt any of the ideas are novel enough to actually get published in one of the "real" nature journals. In fact that paper could have easily been published on a blog . Is this the future of science publishing? Is it a good thing?
