The nobel prize of chemistry has been given this year to the americans Roger Tsien and Martin Chalfie and to the japonese Osamu Shimomura for their works about fluorescent proteins which can detect carcinomas.
Those 3 people studied jellyfishes since 1962 and they discovered the green fluorescent protein which has an important function in the development of the biochemistry.
Osamu Shimomura, born in 1928 at Kyoto, worked long time in american laboratories, specifically at Boston. Martin Chalfie, born in 1947, is a biology teacher at the Columbia university at New York and Roger Tsien, born in 1952, is also a teacher since 1989 at the university of California at San Diego.
