Making the paper.

The article focuses on the career of Cheng-Ming Chuong, a developmental biologist at the University of Southern California in Los Angeles. Chuong has interest on how feathers are generated in adult birds. He decided to try to track down the location of stem cells in feathers. Chuong and his team discovered that in flight feathers, the ring of stem cells tilts towards the side where the quill arises. He plans to continue his characterization of feather stem cells.
