    It was 1995, and Ellen Heber-Katz ran a busy lab at the Wistar Institute in Philadelphia, at the top of a thriving career in auto-immunity. Her lab housed many mice in common cages, labeling the mice with tiny holes punched in their ears. One day, she discovered that a litter of mice were un-labeled, and she spoke to her post-doc about it. But Lise Clark said she was sure she had punched their ears. So Heber-Katz punched their ears herself, and checked back the next day. She could hardly see the holes she had punched. Within a few days, the ears healed over, smooth skin, seamless cartilage with nary a scar. Mice aren’t supposed to be able to do this.
