The gene sequencing future is here

As recently as the 1980s, scientists collected genetic data by laboriously tracking the diffusion of DNA molecules through slabs of gel. Now researchers stand by as machines gush billions of letters of DNA code a day, and struggle to cope with the data deluge.

In the past two decades, the speed of sequencing has leapt from around 10,000 bases per day per machine to more than 1 billion (above, blue). Since the introduction of high-throughput machines in the mid 2000s, costs have plummeted (abov...
