Alzheimer's breakthrough: Scientists have found a potential cause of the disease in the behavior of immune cells.

tl;dr from the article:
Researchers at Duke announced that their studies of Alzheimer’s in mice had thrown up a new process they believe contributes to the disease’s development.
They observed that in Alzheimer’s, immune cells that normally protect the brain instead begin to consume a vital nutrient called arginine.
By blocking this process with a drug, they were able to prevent the formation of ‘plaques’ in the brain that are characteristic of Alzheimer’s disease, and also halted memory loss in the mice.
Everything else in the article basically restates those points in different ways.
