Here's the latest on molecular biology / biotechnology advances and our furry friend, the Woolly Mammoth. Unlike most dinosaur fossils, Woolly Mammoth remains are often found in frozen, less-deteriorated states in Siberia; and often contain viable proteins such as collagen, from which genetic sequences can be produced.
