Our November issue is out, and it's a focus on chemical systems biology. My colleague Joanne points out that, from cell phones to social networking and even to Nature Network, life is increasingly interconnected. Thus, this focus issue highlights how networks are coming to chemical biology – and chemists to systems biology.

Do you think, as Randy Peterson suggests, that chemical biologists have reductionist tendencies? As Andrew Hopkins writes, is network pharmacology going to be the next era in drug discovery? What systems are you interested in, and more broadly, how do you define a systems approach? Finally, what do you think of our new term (chemical systems biology)? What terms have you coined, or would like to?

All this reminds me that I've still got to figure out a system for organizing the papers on my desk. So, I'd better get to it!
