The Democrats are advancing two lies right now.
The first is that President Bush has banned stem cell research. He hasn't. He has merely limited embryonic research.
The second is that embryonic stem cell research will find a cure for Alzheimer's disease. It won't. Alzheimer's disease is a whole brain disease. Developing new cells for part of the brain won't fix the problem with the whole brain.
Thankfully, real science is aware of this fact. It looks like scientists actually doing the research are on the right path. Fox News reports on research for a new treatment to fight the plaque in the brain associated with the disease.
