Physical activity reduces stress-related brain activity to lower cardiovascular disease risk

New research indicates that physical activity lowers cardiovascular disease risk in part by reducing stress-related signaling in the brain. In the study, which was led by investigators at Massachusetts General Hospital (MGH), a founding member of the Mass General Brigham... Continue Reading →

Gene Therapy Restores Hearing in Children with Hereditary Deafness

A new study co-led by investigators from Mass Eye and Ear, a member of Mass General Brigham, demonstrated the effectiveness of a gene therapy towards restoring hearing function for children suffering from hereditary deafness. In a trial of six children... Continue Reading →

The fountain of youth is … a T cell?

Buck Scientists Identify How Dietary Restriction Slows Brain Aging & Increases Lifespan

Restricting calories is known to improve health and increase lifespan, but much of how it does so remains a mystery, especially in regard to how it protects the brain. Buck scientists have uncovered a role for a gene called OXR1 that is... Continue Reading →

NASA Analysis Confirms 2023 as Warmest Year on Record

Earth’s average surface temperature in 2023 was the warmest on record, according to an analysis by NASA. Global temperatures last year were around 2.1 degrees Fahrenheit (1.2 degrees Celsius) above the average for NASA’s baseline period (1951-1980), scientists from NASA’s... Continue Reading →
