A new report shows that Arizona's economy benefits by more than $1 billion from research at the state's public universities.

The Arizona Board of Regents recently released its research report that covers 2012. It details the economic impact of research at Arizona State University, Northern Arizona University and the University of Arizona.

Board chairman Rick Meyers says the research leads to inventions, patents and start-up companies that fuel the private sector and create jobs.

Examples of ongoing research include a technique to detect bone loss, the science of placebos and the discovery of new treatments for disease.
