Summary, so people don't have to suffer through the damn pop ups and slow loading pages:
A research team has a 'Petri dish model' of Alzheimer's, a biological culture that demonstrates the plaque formation and tangles characteristic of the disease progression in the brain. The model shows the amyloid plaque formation comes before the formation of the 'tangles' in structure. The model, if validated against the actual disease, provides a path for more rapid testing of treatments.
