Keck School of Medicine of USC researchers discover through happenstance that mice have their own form of ‘first aid’ practices to help other mice in need.

Mass General Brigham-led researchers investigated data from over 200,000 individuals who were followed for more than 30 years, and found that higher intake of plant-based oils, especially soybean, canola, and olive oil, was associated with lower total, cancer, and cardiovascular disease mortality, whereas butter intake was associated with increased risk of total and cancer mortality. The researchers also found that less than a tablespoon of butter per day with equivalent calories of plant-based oils could lower cancer deaths and overall mortality by 17%.

A recently launched Phase 1 clinical trial at Mass General Brigham is examining the safety and feasibility of a groundbreaking treatment approach for Parkinson’s disease in which a patient’s stem cells are reprogrammed to replace dopamine cells in the brain. The first-of-its-kind clinical trial, based on more than three decades of research from McLean Hospital's Ole Isacson, has treated three-of-six participants who will be tracked for more than a year.
