Here is a simple Greasemonkey script to get postgenomic links in Nature journals.

Big disclaimer: It's my first greasemonkey script and I don't really know much about JavaScript :)

The trick is going to make the script useful in any science journal. If anyone is good with Xpath and/or finds a much simpler way of doing it feel free to edit the script.

To use copy-paste the script into a file and name the file (something.user.js). Drag the file into a firefox window to install.

Alternatively you can install the script by clicking on this link postgenomic.user.js, Firefox will recognise the file as a Greasemonkey script and prompt you to install it.

Then go to a nature journal and browse around the table of contents. You should find some papers with the logo of Postgenomic below the DOI.
