In the decade that has passed since the completion of the first draft sequence of the human genome, biologists have grown increasingly aware of a problem ironically generated by the success of their work. Biological experiments in the age of genomics -- including DNA sequencing, gene expression profiles, studies of cell-signaling pathways, protein binding, and other information-rich inquiries -- generate quantities of raw data so immense that they threaten to overwhelm researchers' ability to make sense of them.
