STOCKHOLM, Oct. 8 (Xinhua) -- Two U.S. scientists, Mario R. Capecchi and Oliver Smithies, and Martin J. Evans of Britain won the 2007 Nobel Medicine Prize on Monday.

The trio were awarded for a series of "groundbreaking discoveries concerning embryonic stem cells and DNA recombination in mammals," according to the Nobel jury.

Both Capecchi and Smithies are U.S. citizens but were not born in America. Capecchi was born in Italy and Smithies was born in Britain.

The winners of the Physics Prize will be announced on Tuesday, to be followed by those for Chemistry on Wednesday, Literature on Thursday, Peace on Friday and Economics on next Monday respectively.

The annual Nobel Prizes are usually announced in October and are handed out on Dec. 10, the anniversary of the 1896 death of Alfred Nobel, a Swedish industrialist and the inventor of dynamite.

Nobel died childless and dedicated his vast fortune to create "prizes to those, who, during the preceding year, shall have conferred the greatest benefit on mankind."

The prizes have been awarded since 1901. Each prize consists of a medal, a personal diploma and a cash award of 10 million Swedish kronor (1.53 million U.S. dollars).
