A doctoral student’s suggested experiment may rewrite chemistry textbooks

Professor Stephen Bradforth took a chance on Ryan McMullen’s expensive and potentially dangerous student proposal. It’s led to a new understanding of what defines a metal — and the cover of Science magazine.

Scientists discover how a protein that calms brain activity works

The findings from USC researchers provide a clear path to uncovering new drugs to control addiction, pain and neurological disorders such as epilepsy and muscle spasticity.

Polluted river sparks first-gen student’s dreams of environmental change

Juan Pablo de los Rios grew up on both the Mexican and American sides of the Rio Grande, which became a dumping ground for toxic waste. As a chemistry grad student at USC Dornsife, he hopes to one day clean that river and others like it.
