A snapshot of Alzheimer's

Scientists have taken detailed images of one of the proteins involved in Alzheimers Disease for the first time, which may help researchers create treatments for the disease.

Alzheimers is characterized by a buildup of two proteins, tau proteins inside of neurons and amyloid plaques on the outside. Healthy tau proteins look sort of like fiber-optic cables that help support neurons. But sometimes, those proteins become tangled, and the tangles can build up and warp the neuron's shape, rendering them useless.

Why it matters: Tau tangles have been implicated in a number of neuro-degenerative diseases, including Alzheimer's, Huntington's and Parkinson's Disease. These detailed images allow scientists to parse apart the molecular structure of the tangles, which could help them understand why the tangles happen, how they spread, and possibly even develop drugs to treat them.
