Good find, kiwi33. I've been on the lookout for other articles like this concerning the Stolzenberg et al. paper that Tupelo3 brought to our attention last week.

There is also an article on the AlzForum website. It includes (at the bottom) an interesting comment from an independent academic, and a response from Michael Zasloff (research leader).

I'm expecting the SoPD blog to cover this paper as well, sometime in the near future.
