Bowhead whales can live for more than 200 years, and a recently discovered protein might be the reason.
Researchers found that the cold-induced RNA-binding protein enhances DNA repair, specifically fixing double-stranded DNA breaks.
This protein not only contributes to the whales' longevity! but also extends the lives of Drosophila flies and enhances repair in human cells.
The protein enhances repair of double-stranded DNA breaks, a particularly troublesome kind of damage.
