David Weitz and his team of Harvard University physicists are attempting to adapt microfluidics technology to sequence DNA, reports MIT's Technology Review. If they succeed, the price of sequencing a human genome could plummet to about $30. The technology, which was developed in Weitz's lab, uses picoliter droplets of water as test tubes, says Technology Review's Emily Singer. The droplets can be moved around on a microfluidics chip, injected with chemicals, and sorted based on their color.
