There is a revolution in knowledge under way. New technologies capable of producing DNA and RNA sequences at low cost are providing us with hitherto unimaginable amounts of data about how biological organisms function. This availability of this data shifts a large part of life sciences into the information sciences. Bioinformatics will be a key technology in the advancement of Medical, Environmental, and Energy sciences in coming years. The ability to read DNA, understand gene expression in RNA and understand the resulting proteins will understand and cure numerous forms of cancer, understand and delay the onset of debilitating conditions like diabetes, alzheimer’s, and depression. It will help us respond to environmental polutents and it will help in the production of bio-fuels.
