Here are my picks of some interesting discussions happening or just getting started on Nature Network.

The Nature Precedings forum has a thread about how to objectively weed out pseudoscience from real science. The question came up when a user complained about a particular paper posted to Nature Precedings (the new preprint server for biology), but quickly expanded into a larger discussion about what criteria should be used to determine whether something is pseudoscience. It’s an important issue that reaches beyond Precedings, especially in this day and age when increasingly sophisticated pseudoscientists are dressing up their work as real science, making it harder for people to pick out the chaff from the wheat.

Craig Rowell, a postdoc working on breast cancer at Duke and one of our more active users, is asking members of the postdoc and grad student group to post stories about their friends who have moved on to other career opportunities after their postdocs. This would be a good way to learn from the experiences of others about life beyond the postdoc.

For those of you based at MGH in Boston, check out the MGH group. Henry Lin, a postdoc there, is asking fellow MGHers a similar question: what are your goals post-Harvard?

And for you structural biologists out there, join the NMR group. The group’s moderator, Michael Durney, a Harvard postdoc, recently posted some commentary about a paper he saw in Nature Methods.

Finally, the Nature Protocols forum has always been hugely popular. Use it to get your questions answered about experimental protocols.
