00:47 How bowhead whales live so longResearchers have uncovered a protein that enhances DNA repair and may explain how bowhead whales can live more than 200 years. The protein, cold-induced RNA-binding protein, was shown to enhance repair of double stranded DNA breaks, a particularly troublesome kind of damage. The team showed that this protein could also extend the lives of Drosophila flies and enhance repair in human cells. More needs to be understood about how this protein works, but the researchers hope that it could, one day, help prevent cancer and ageing in humans.Research Article: Firsanov et al.News: This whale lives for centuries: its secret could help to extend human lifespan11:22 Research HighlightsA precise way to grow crystals, with lasers — plus, the specialist organ that allows stinkbugs to protect their eggs from wasps.Research Highlight: How to grow crystals when and where you want themResearch Highlight: Stinkbug ‘ear’ actually hosts parasite-fighting fungi13:3
