A cold-activated protein that mends damaged DNA could play a part in keeping the bowhead whale in tip-top shape.
Heidi Ledford reports for Nature from Seattle, Washington.
The bowhead whale (Balaena mysticetus) can live for more than 200 years, thanks in part to a highly effective DNA-repair protein.
Encased in a blanket of blubber that is nearly half a metre thick, and with a habit of smashing head-first through Arctic ice, the 80,000-kilogram bowhead whale does not, at first glance, seem a natural poster child for health and longevity.
