Genes, Neurons, Internet Found to Have Organizing Principles-Some Identical

How do 30,000 genes in our DNA work together to form a large part of who we are? How do one hundred billion neurons operate in our brain? The huge number of factors involved makes such complex networks hard to crack. Now, a study published in the October 25 issue of Science uncovers a strategy for finding the organizing principles of virtually any network ? from neural networks to ecological food webs or the Internet.
