Want to read the first research published from NASA's Mars Curiosity expedition? That'll be $20, per paper, for a one-day pass. Or, at least, that's how much it would cost you to read those reports through Science, the journal that published them. Last Thursday, Michael Eisen, a biologist who founded the open-access journal Public Library of Science, put up a blog post in which he released free pdfs for all five of NASA's Curiosity papers. Meanwhile, Mother Jones has a profile on Eisen, which goes more in-depth into his campaign to make taxpayer-funded research more easily available to the taxpayers, themselves.
