The Scientist is running a good commentary on the relevance of stem cell research to Alzheimer's. It's worth reading in light of press attention (and confusion) over Ronald Reagan's legacy. The digest version is that stem cell research is not the field producing the best results for Alzheimer's therapies right now, but is likely to lead to relevant results in the future - with some qualifications. Scientists tell us that it is too early to know, and if we'll certainly never know if the research is banned! Unfortunately, this distinction seems a little too complex for many journalists: they are attempting to conflate Alzheimer's, Reagan's legacy, US administration policy, and Nancy Reagan's views on embryonic stem cell research into one simple sound bite.
