Medical Research Scholars Reflect on Their NIH Journeys

Future Physician-Scientists Spent a Year in IRP Labs

Many doctors not only treat patients directly, but also make valuable contributions to research that will improve medical care in the future. Each one of these talented ‘physician-scientists’ began his or her research career under the guidance of a more senior scientist. At the NIH, the Medical Research Scholars Program (MRSP) provides just such an experience to promising young medical students from all across the United States.

In yet another example of the anti-aging powers of eating less — what scientists call caloric restriction — IRP researchers have identified the specific aging-induced cellular and molecular changes in arteries that are curbed by substantially reducing calorie intake.
