It's the Network, Stupid: Why Everything in Medicine Is Connected

PLoS Medicine gets excited about networks.

From the editorial piece: "One need look no further than Facebook to appreciate the significance and power of social networking. (Even PLoS has its own thriving Facebook community, which you can join [here].) But social networking is about more than just friends reunited; it's a framework for understanding even the most basic of biological processes. Two papers in this month's PLoS Medicine illustrate the insight that network theory brings to basic science, and the valuable interdisciplinarity that social network analysis can inspire."
