RALEIGH -

(AP) - Duke University first home-grown Nobel Prize winner says nothing is better than sharing the honor with a former student.
    
The Royal Swedish Academy of Sciences on Wednesday awarded Duke's Dr. Robert Lefkowitz and Brian Kobilka, who's now at Stanford University. They were honored for groundbreaking discoveries on how receptors on the surface of cells can be blocked or encouraged with chemicals. About half of all medications act on these receptors.
    
Lefkowitz did all of the winning research since arriving at Duke in 1973. Lefkowitz says Duke medical school leaders accepted what he called an outrageous list of demands to lure him from Harvard. Lefkowitz says they upped their salary offer to $32,000, then didn't give him a raise for four years.
