00:47 How bowhead whales live so long
Researchers 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.

13:31 An antivenom against a broad range of snakebites
Researchers have used ‘nanobodies’ to create an antivenom that works against 17 snake species’ venom. Snakebites kill millions each year, so getting the right antivenom can be life or death. But they are difficult to produce and often are very specific. Now, using nanobodies from llamas, researchers created an antivenom against a broad range of snake species’ venom. The new antivenom can now even be produced without the llamas, and the team hope it will pave the way for a more universal antivenom.
