"Researchers have uncovered a protein that enhances DNA repair and might explain how bowhead whales can live for 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."
"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."
A cold-induced RNA-binding protein enhances repair of double-stranded DNA breaks and may explain how bowhead whales can live for more than 200 years. The protein improves repair of particularly troublesome DNA damage, extends the lives of Drosophila flies, and enhances repair in human cells. The mechanism requires further elucidation but could eventually help prevent cancer and ageing in humans. Separately, llama-derived nanobodies were used to create an antivenom effective against venom from 17 snake species. The antivenom can now be produced without llamas and could enable a more universal, broadly protective treatment for snakebite. Additional highlights include stinkbug egg-protecting fungi and laser-directed crystal growth.
