Dark matter exists! In another example of science blogs as news sources, this story quotes Sean from Cosmic Variance. He writes about the discovery in this post. For the hardcore, the paper is now in the astro-ph archive, in multiple formats. When, oh when, will biologists get a preprint archive?
Rather less exciting is the continuing hobbit debate, which is in danger of becoming tedious. The latest round (“pygmies not species”) is now published in PNAS (open access). There’s excellent discussion at John Hawks Anthropology Weblog.
