The Megathon is a one-hour event on April 13, during which thousands of people will play an online game to help answer a key Alzheimer's research question. Anyone can play - no experience necessary. In the game, you look at movies from the brains of mice and try to identify vessels as flowing or stalled. Middle school students, seniors, caregivers and Alzheimer’s patients themselves can play the game.This helps to speed up Alzheimer's disease research at Cornell University. You can join this event at the library as part of Citizen Science Day. You can sign up early at stallcatchers.com and practice or just come in.
