The future of ribosomes

Maria Barna is an authority on ribosomes – “life’s most ancient and spectacular molecular machines.” Ribosomes make proteins in the body. There can be a thousand different types of ribosomes in a single cell, she says, each with a specific job to do. But sometimes things go awry and ribosomes get “hijacked,” leading to disease. Barna studies these “diabolical” variations to find new therapies to treat diseases ranging from cancer and COVID to Parkinson’s. When diseases hit, it’s all about the ribosomes, Barna tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.Have a question for Russ?
