Two scientists who unlocked some of the mysteries linked to obesity or a professor who figured out how to make stem cells without human embryos could be candidates for the medicine award when the first of the 2011 Nobel Prizes are announced Monday.
Canadian-born Douglas Coleman and American Jeffrey Friedman have won several prizes for their discovery of leptin, a hormone that regulates food intake and body weight, and could be in the running for the coveted prize worth 10 million kronor ($1.5 million).
