Traditionally, woolly mammoths were believed to have gone extinct around the same time as the giant deer, together with all the other extinct 'Ice Age' beasts such as the woolly rhino and saber-toothed cat, between about 12,000 and 10,000 years ago.

Capecchi says cancer specialists have believed alveolar rhabdomyosarcoma originates in satellite stem cells because the tumors proliferate after birth, when stem cells retain their ability to proliferate but mature muscle fibers normally do not.
