An anonymous reader writes "PLOS — the Public Library of Science — is one of the most prolific publishers of research papers in the world. 'Open access' is one of their mantras, and they've been working to push the academic publishing system into a state where research isn't locked behind paywalls and subscription services. To that end, they've announced a new policy for all of their journals: 'authors must make all data publicly available, without restriction, immediately upon publication of the article.' The data must be available within the article itself, in the supplementary information, or within a stable, public repository. This is good news for replicating experiments, building on past results, and science in general."
