Join our Beta-test (no pun intended) by playing our new citizen science game to speed up Alzheimer's research.

We at the Human Computation Institute are currently developing a citizen science game to help speed up Alzheimer’s Disease research at University of California Davis (UC Davis) and University of California San Francisco (UCSF), which will help us better understand why Hispanic people are more likely to develop Alzheimer’s than non-Hispanic White people.

Similar to our game Stall Catchers, which you can play here, anyone across the globe will be able to identify and annotate neuropathology the same way an expert researcher would in the lab.

By participating in this Beta-test, you will help us test the game by annotating beta-amyloid plaques, a hallmark of this disease, just like a professional pathologist.

If you want to know more details about the Beta Catchers Terms and Privacy Policy and this test, you can read here.

Who can participate?

All are encouraged to participate, especially people who identify as Latino and Hispanic!

Anyone with a computer can join the study, no previous knowledge is needed.

How to participate?

Sign up at, watch the video tutorial, and try out our new citizen science game. To complete your participation in the Beta-test, you will have to analyze 100 brain images of Alzheimer's patients.
But don’t worry! You will have until Friday, January 27 by 5 p.m. (EST) to finish the game. The first 100 participants to complete the study and answer a short survey will receive an Amazon gift card (we’ll send it to the email you registered with).

Thank you for taking the time to help us! Your participation in our Beta test will help researchers at UC Davis and UC San Francisco answer key questions about disparities in Alzheimer's disease prevalence between Hispanics and non-Hispanic whites.
