A protein in spider venom may help protect the brain from injury after a stroke, according to research.
Scientists found a single dose of the protein Hi1a worked on lab rats.
They said it showed "great promise as a future stroke treatment" but had not yet been tested in human trials.
The Stroke Association said the research was at its early stages but it would "welcome any treatment that has the potential to reduce the damage caused by stroke".
