Stockholm: Two scientists who unlocked mysteries linked to obesity or a professor who figured out how to make stem cells without human embryos are among potential candidates for the 2011 Nobel Prize in medicine.
Canadian-born Douglas Coleman and American Jeffrey Friedman have won several prizes seen as precursors to the 10 million kronor (USD 1.5 million) Nobel for discovering a hormone that regulates food intake and body weight.
Leading Nobel guesser Karin Bojs, of the Swedish newspaper Dagens Nyheter, said today that Japan`s Shinya Yamanaka could be a contender for discovering that stem cells
can be made from skin cells.
The medicine announcement tomorrow will be followed in the coming days by announcements for prizes in chemistry, physics, literature, peace and economics.
