It can not only regenerate amputated limbs, damaged lungs and severely injured spinal nerves, but also regenerate parts of a damaged brain. On July 1, American and German scientists revealed their discovery about how axolotls regrew amputated legs. They hope that this study will help researchers apply this ability to humans.
