RALEIGH, N.C. (AP) — Duke University landed its first home-grown Nobel Prize winner on Wednesday with the chemistry honor for research that led to better medicines, and the scientist said nothing was better than sharing it with a former student.

The Royal Swedish Academy of Sciences on Wednesday honored Duke’s Robert Lefkowitz and Brian Kobilka, now at Stanford University School of Medicine, for groundbreaking discoveries on how receptors on the surface of the body’s cells work. About half of all medications act on these receptors.
