With their large buck teeth and wrinkled, hairless bodies, naked mole rats won’t be winning any awards for cutest rodent. But their long life span—they can live up to 30 years, the longest of any rodent—and remarkable resistance to age-related diseases, offer scientists key clues to the mysteries of aging and cancer.
