Wired April 21, 2008 Thomas Goetz	Why Medicine Should Care Less About "Sick," More About "Normal" Predictive medicine relies on knowing ranges of normal values so that it can screen for results outside of this range early on. Unfortunately, funding organizations are not interested in what is normal.
Wired April 21, 2008 Rachel Swaby	Chromosome, Proteome ... Decoding the DNA of '-omes' The genome alone can't explain how our bodies work. We need to decode a lot of other complex biological systems that regulate how we develop.
