The seven winners of the biennial Kavli Prizes will share $3-million in prize money, the Norwegian Academy of Science and Letters announced on Thursday. Sharing the prize in astrophysics are David C. Jewitt of the University of California at Los Angeles, Jane Luu of the Massachusetts Institute of Technology’s Lincoln Laboratory, and Michael E. Brown of the California Institute of Technology. The nanoscience prize was awarded to Mildred S. Dresselhaus of MIT. Cornelia Isabella Bargmann of Rockefeller University, Winfried Denk of the Max Planck Institute for Medical Research, and Ann M. Graybiel of MIT shared the neuroscience prize. Mr. Jewitt and Ms. Luu’s award comes just days after they received a $1-million Shaw Prize in astronomy.
