     Animals like woodpeckers and head-ramming sheep manage to protect their brains from damage, the researchers point out. So why can't we? Of course, in our case the head ramming is in the name of fun. But there might be ways to safeguard our brains, like these animals do, from the inside out.

     When sperm whale researcher Rui Prieto shouted “head ramming!” during a routine day of research off the coast of Spain, the scientific team on board was understandably excited. After all, this type of whale behavior is rarely witnessed, let alone documented. [...] But when drone footage captured some of the whales headbutting each other, the researchers’ attention shifted. The drones recorded three instances of sperm whales engaging in head ramming behavior. This marked the first time scientists had ever documented this long-reported behavior on video.
