that was going on in our labs and the work that was done by two individuals, martinjinek and krzysztof chylinski latest enzyme cas9 functions. once we understood how it could be programmed with rna and how to engineer the rna into a simpler form than what we find in nature, we have sort of realise that this would be an incredibly powerful tool for manipulating genomes. because at that stage, you knew that it would work in humans too. because it would be possible to cut any type of dna from our experiments, yeah. do you remember how you felt at the time and what you did? well, i remember leaning over the light box in the lab and looking at the results of an experiment with martin, and looking at each other and saying "wow, this is an incredible protein and it seems likely to be useful for genome editing." 0k, well, let's look at a few of the things that even in a few years, that was back in 2012, in the year since that it has already started to be useful in labs all around the world. there are people looking at all sorts of diseases to try to cure, not least the chinese, the blood disease, there
