The gene sequencing future is here

BIG DATA  Improvements in genome sequencing technology over the past two decades has boosted the speed and cut the cost of decoding DNA.

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 (above, orange) and the price of sequencing a whole human genome (above, gold) has tumbled almost to the long-anticipated figure of $1,000.
