http://www.bbc.co.uk/news/technology-16068581 Russian scientists to attempt clone of woolly mammoth Scientists from Russia and Japan are undertaking a Jurassic Park-style experiment in an effort to bring the woolly mammoth out of extinction. The scientists claim that a thigh bone found in August contains remarkably well-preserved marrow cells, which could form the starting point of the experiment. The team claim that the cloning could be complete within the next five years. But others have cast doubt on whether such a thing is possible. Mother cow? The team, from the Siberian mammoth museum and Japan's Kinki University, said that they planned to extract a nucleus from the animal's bone marrow and insert it into the egg of an African elephant. Similar procedures have been done before with mixed results.
