A Mammoth Discovery

The remains of a baby mammoth could explain why the ancient species became extinct, scientists said on January 4. The four-foot-tall calf, nicknamed Lyuba, was found last May in northern Siberia. It had been frozen for about 37,500 years. The cold kept Lyuba's body from breaking down. The calf still has some fur.

Last month, Lyuba underwent a CT scan. A CT scan creates 3-D pictures of the inside of the body. Scientists will use the images to study Lyuba's structure. They could even get a glimpse of what it ate. Japanese scientist Naoki Suzuki is leading the first part of the study. "This is what we've all been waiting for the chance to explain everything about the mammoth," he said.
