Almost 150 different genomes have been sequenced to date, including the human genome. But sequencing needs are growing faster than ever: In March 2003, the Bush administration announced it will spend $1 billion over five years to increase forensic analysis of DNA, including a backlog of up to 300,000 samples. And the success of the growing field of genomic medicine, which promises to deliver better therapies and diagnostics, depends on faster sequencing technology.
