IBM’s “DNA Transistor” Could Sequence Genomes on the Cheap

When the Human Genome Project finished sequencing the first human genome earlier this decade, the price tag for the endeavor had reached almost $3 billion. Now, IBM has announced details of its effort to bring the cost of sequencing a person's genome down to below $1,000--and the company says it could go as low as $100. While IBM is hardly the only company racing towards these goals, the company's chip-based approach makes it a serious contender. The company's technique involves
