Bruce Nathan Ames (born December 16, 1928) is a prominent American biochemist. He is a professor of biochemistry and Molecular Biology Emeritus at the University of California, Berkeley, and was a senior scientist at Children's Hospital Oakland Research Institute (CHORI). Throughout his career, Dr. Ames has made significant contributions to understanding the mechanisms of mutagenesis and DNA repair. One of his most notable achievements is the invention of the Ames test, a widely used assay for easily and cheaply evaluating the mutagenicity of compounds. The test revolutionized the field of toxicology and has played a crucial role in identifying numerous environmental and industrial carcinogens. Source: Wikipedia (en)
