The study, published in Science, focused on a gene known as MUC19, which is involved in the production of proteins that form saliva and mucosal barriers in the respiratory and digestive tracts. The researchers show that a variant of that gene derived from Denisovans, an enigmatic species of archaic humans, is present in modern Latin Americans with Indigenous American ancestry, as well as in DNA collected from individuals excavated at archeological sites across North and South America.

A new study by USC Leonard Davis School of Gerontology researchers shows that Americans with less education are aging faster than their peers with more schooling, and the gap has grown over the last 30 years.

The study examined “biological aging,” which goes deeper than simply counting birthdays. Biological aging measures how the body is changing over time, including how well organs and systems are working.

A new study led by Mass General Brigham found that AI-powered ambient documentation technologies significantly reduce physician burnout—by 21.2% at Mass General Brigham and with a 30.7% improvement in documentation-related wellbeing at Emory Healthcare —while also freeing up time for more meaningful patient interactions. Providers reported feeling more connected to their work, reclaiming personal time, and experiencing a renewed joy in practicing medicine, highlighting the transformative potential of this technology in improving clinician wellbeing and patient care.
