Photo by Jeff Fitlow b. A ruthenium-based tag developed at Rice takes advantage of fluorescent anisotropy to measure the rotation of amyloid beta oligomers as they grow in solution. Small aggregates rotate fast, while large oligomers rotate slowly, a characteristic that lets researchers watch as they grow. Amyloid beta oligomers are toxic to neurons and implicated as a possible cause of Alzheimer’s disease. Courtesy of the Angel Martí Group

Alzheimer’s disease destroys neurons that keep us awake

A study suggests Tau tangles, not amyloid plaques, drive daytime napping that precedes dementia.

Direct toxic action of beta-amyloid identified

Scientists have identified early cellular dysfunction in Alzheimer's patients who have already developed clinical symptoms contain large clumps of the protein beta-amyloid, known as plaques.
