A new study of the bizarre naked mole rat shows that the animals have evolved a DNA repair mechanism that could explain their longevity.

These burrow-dwelling rats have a maximum life span of nearly 40 years, making them the world's longest-lived rodent.

The new findings, published in the journal Science, could also shed light on why naked mole rats are resistant to a wide range of age-related diseases.

The animals are resistant to cancer, deterioration of the brain and spinal cord, and arthritis, so many scientists want to understand more about how their bodies work.
