FILE - In this file photo dated December 10, 1948, Nobel Prize winners of 1948, shortly after being presented their prize inside the concert hall in Stockholm, Sweden. English writer T.S. Eliot Nobel Prize for Literature and the Swiss Scientist Paul Mueller Nobel Prize for Medicine. Mueller was honored for discovering that the powerful pesticide DDT killed flies and mosquitoes to fight Typhus and Malaria, but ended up doing both good and bad as it also poisoned wildlife. Nobel Prizes cannot be changed or revoked, so the judges must put a lot of thought into their selections, with this year's awards due to be announced over the next two weeks. (AP Photo/FILE)
