Story summary

Researchers at the University of Rochester identified CIRBP as a key protein linked to bowhead whale lifespans exceeding 200 years.
CIRBP is found at about 100 times higher levels in bowheads than in other mammals and aids DNA repair.
The study, published in Nature, notes that lower temperatures enhance CIRBP activity.
Researchers are exploring whether increasing CIRBP levels in humans could inform strategies to extend lifespans.
