Dec. 30, 2025: Colorado researcher on drug that holds promise for treating Alzheimer's; Denver's missed climate goals

There's promising new research out of Colorado in the effort to treat Alzheimer's disease. The study focused on the drug Leukine, which is already on the market to treat other disorders. Andrea speaks with the study's senior author, Huntington Potter, who directs the University of Colorado Alzheimer's and Cognition Center. Then, another study shows how lifestyle can help prevent memory loss. Also, the city of Denver won't meet its first big climate goals.
