A new discovery may unlock the answer to a vexing scientific question: How to conduct mitochondrial replacement therapy, a new gene-therapy technique, in such a way that safely prevents the transmission of harmful mitochondrial gene mutations from mothers to their children.

New study of mice by OHSU researchers suggests judicious use of combined radiation and immunotherapy for cancer.

Long-term exposure to cosmic radiation could alter the brain and change behavior in astronauts bound for Mars, according to new research led by scientists at OHSU in Portland, Oregon.

An analysis of data from 19 clinical trials, led by the OHSU Pacific Northwest Evidence-Based Practice Center, found that using statin drugs provided wide-ranging prevention benefits without significantly increasing the risk of serious side effects in people who have not had a previous heart attack or stroke.
