Learn More About Stall Catchers
Did you know… Citizen Science is one of GSUSA’s (inter)national service projects?!? USAGSO is excited to help our girls explore citizen science and contribute to Alzheimer’s research by partnering with Stall Catchers throughout the year.
How can you play a part in solving some of the biggest problems facing our planet? Enter citizen science, where volunteers help scientists collect data for their studies and experiments. Anyone can be a citizen scientist—all you need is curiosity and a willingness to help!
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 to speed up Alzheimer's Disease research at Cornell University. Anyone can play this online game — no experience necessary. Currently, catchers range from 6 to 88 years old. A large part of the Stall Catchers community includes middle school students, seniors, caregivers and even Alzheimer’s patients themselves.
