The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
bowhead whales’ efficient DNA break repair explains why they live so long
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
Scientists at the University of Rochester discovered that bowhead whales, which can live over 200 years, produce extremely high levels of a DNA-repair protein called CIRBP (Cold-Inducible RNA-Binding Protein).
When researchers introduced the whale version of CIRBP into human cells, DNA repair became more efficient.
