Giant, meat-eating ground sloth, doggie toy words, and how to see cancer. These are the stories you may have missed this week.

Reconstruction of the South American giant ground sloth Mylodon darwinii feeding on the carcass of the hoofed native herbivore Macrauchenia. These extinct mammals roamed the Pleistocene landscape of Patagonia and other parts of high and mid-latitude South America, like this reconstructed scene from about 12,000 years ago in front of the famous Mylodon Cave (Cueva del Milodón) in southern Chile.
