This Week in Nature: Feb 15, 2007

Today's issue of Nature offers a slew of goodies to read.

In this editorial, Nature alerts readers to a change in policy that will allow authors to "present full experimental methods as an integral part of their paper" instead of the ultra-short section that's currently the standard.

A news item checks in on genome-wide association studies, which so far haven't lived up to their initial promise, according to the article. Now, however, research is proving that these kinds of association studies are indeed going to have a significant impact on the biomedical landscape.

Another news story talks about the rise of Wiki culture in the scientific community, and lets readers know about a test version from bioinformaticist Barend Mons, who invites scientists to help him build a seamless central database of gene and protein information, for one thing.

Finally, a paper from lead author Christopher Striemer at the University of Rochester demonstrates nanofabricated silicon membranes that can be used to separate proteins and other biomolecules faster than current separation methods.
