UCLA and UCSF researchers discovered why some brain cells resist Alzheimer's better than others. A natural cleanup system removes toxic tau protein before it forms deadly clumps.

Scientists developed a simple blood test that could predict not only if someone will develop Alzheimer's disease, but when symptoms might start. The breakthrough could help doctors intervene earlier when treatments work best.

University of New Mexico researchers discovered an enzyme that controls tau protein buildup in the brain. When they turned it off, toxic tau vanished and neurons stayed healthy, opening new hope for Alzheimer's treatment.
