The fine chaps and chapesses at Genomes Unzipped have a few guest bloggers writing excellent posts about the implications of cheap and quick genome sequencing. I don't think I have opined much on this topic on my own blog, but I'm turning into a bit of a genome bore on other people's blogs. Do your civic duty, and dilute my inane comments with some of your own! I particularly liked Clive Jones's recent post, but Adam Rutherford's is also good.
Genetics is entering a new era; Clive calls it "disruptive" - in the same way as mobile phones were a disruptive technology that totally changed the communications sector. I agree. This is where medicine is at, and we need to think smart to maximise the benefits.
