New era of fast genetic engineering

Sequencing genomes has become easy. Understanding them remains incredibly hard. While the trickle of sequence information has turned into a raging torrent, our knowledge isn’t keeping up. We still have very little understanding of what, if anything, all our DNA does.

But genetic engineering is very difficult and expensive.

At least, it used to be. Last month, two groups announced that they had performed a mind-boggling feat. They targeted and disabled nearly every one of our genes in cells growing in a dish. They didn’t knock out all the genes in each cell at once, of course, but one gene at a time. That is, they individually modified a staggering 20,000 genes.
