Researchers have found evidence of improved dna repair in the long-lived bowhead whale, which may hold clues to understanding its longevity. The discovery of a protein that repairs damaged dna in bowhead whales has been reported, with some outlets suggesting that this mechanism could potentially be used to slow human aging. The findings may also have implications for understanding and treating cancer, although the exact nature of the relationship between bowhead whale dna and human health is still being explored.
