What it is: The newly discovered mutation slows the production of beta amyloid, a protein suspected in Alzheimer's disease, and appears to override a gene that is a strong risk factor for the disease.

What's next: Scientists will evaluate how reducing the protein affects those with typical Alzheimer's.
