NIH Director's Blog

Forty-five years ago, when I was a first-year medical student, a lecturer introduced me to a young man with sickle cell disease (SCD). Sickle cell disease is the first “molecular disease”, with its cause having been identified decades ago. That helped me see the connection between the abstract concepts of molecular genetics and their real-world human consequences in a way no textbook could. In fact, it inspired some of my earliest research on human hemoglobin disorders, which I conducted as a postdoctoral fellow.

A big challenge in unlocking the mysteries of aging is how long you need to study humans, or even human cells, to get answers. But, in partnership with NASA, NIH is hoping that space will help facilitate this important area of research.
