Globally, snakebites kill 80,000 to 140,000 people a year and lead to around 400,000 disabilities. Because many people who are bitten live in rural areas, there is insufficient access to antivenom. To find a solution, Sean Carroll at the University of Maryland in College Park and his colleagues decided to look into how snakes protect themselves against their own venom¹.
