Research team identifies new Alzheimer's gene

... will open a new era in Alzheimer research. When a scientist suspects a particular gene or pathway maybe implicated in Alzheimer’s disease, they will use these data to see if there is genetic evidence supporting their idea. Reviewing these data in an hour will permit them to save months of work and thousands ...
