CNN: Test might detect Alzheimer's early This article is about a possible diagnostic for Alzheimer's (something that we don't have yet--except post-mortem) developed by the laboratories of Bill Klein and Chad Mirkin. The story reports on a paper published in the Proceedings of the National Academy of Sciences (PNAS). The really cool thing is that I work in Bill Klein's lab. This article isn't about my project, but it is about a project in which the post-doctoral fellow with whom I work has been highly involved. Actually, the paper is his, Dr. Klein's, and Dr. Mirkin's. Anyway, this is a preliminary study, but this test might have a lot of potential to help the millions of people who suffer from Alzheimer's. The amyloid-beta derived diffusible ligands (ADDLs) mentioned in the article were first proposed as the toxins responsible for Alzheimer's by an individual working in our lab. That was 6 or 7 years ago, far before I had any clue what pipetteman was. I just thought I would share a very interesting news story that also happens to be personally exciting for me.
