Just to add some info: The update recaps the original, and talks about advances over the year or two since the first one.

It's a great podcast episode.

And if you like the original episode, I also strongly suggest you listen to this: http://www.radiolab.org/story/shrink/

It is not CRISPR-related, but part of the same interview. It was really inspiring.
