Hacking DNA. No, really.

Last year a new genetic engineering technology called CRISPR - Clustered Regularly Interspaced Short Palindromic Repeats - showed up on my radar at a local conference. Long story short, CRISPR is a highly precise technique for editing DNA in situ which follows from the discovery of short sequences of DNA which allow for precise location of individual genes. It's a fascinating technology; there are even tutorials (archived copy, just in case) online for developing your own guide RNA to implement CRISPR/Cas9. What you might not have known is that CRISPR/Cas9 is being actively studied as a theraputic technique in humans …
