Celebrate a Citizen Science Day Megathon! Learn and play Stall Catchers -- Join citizen scientists worldwide and help speed up Alzheimer's research. Stall Catchers is an online game that 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. This helps ongoing research projects. Learn more and create an account at megathon.us. Pre-game intro 10:30-11 a.m., play Stall Catchers from 11-12, learn more and enjoy refreshments from 12-12:30.
