Most of my posts about new scientific advances will be summaries and commentaries based on papers published in major open-access journals. Whilst I have access to all major research journals, some of the most prominent ones (notably, Science, Current Biology, Cell, Neuron) require a subscription to read. By focusing on open-access journals, I can encourage you to read the papers yourself to get the whole story (and/or to check up on me), and I can freely reuse images and other media. Many of the open-access journals are top-flight, especially two of the newest ones, eLife and Cell Reports. Nature Communications is more established and also open access (somewhat recently changed to all open access). I tend to favour the high-quality open-access PLoS (Public Library of Science) journals—PLoS Biology and PLoS Genetics.
The Cell Press journals (Current Biology, Cell, Neuron, Cell Stem Cell) are free after a year, and regularly have free featured articles that are available for a few weeks.
Nature papers can now be read (but not downloaded or printed) by anyone. This means that I will be much more likely to write on Nature articles, which is great news. Read more about the new Nature scheme here.
For general science coverage, I prefer the Guardian, the Independent, and the New York Times.
I do not actively monitor anti-science blogs or sites, but Facebook fills in nicely. I have occasionally visited the discussion forums at Biologos; here is my profile there.
