摘要

Pain is part of an animal's life. It is there to tell us that something is wrong, and needs to be attended to. There is moral pain. And physical pain, the more definable of the two, which serves two purposes. The first, to warn us of tissue damage and, more often than not, its localisation. The second, to understand where danger lies, so as to avoid it in the future. Unless, of course, it has been lethal. Ever since Life emerged, Nature has been using pain as a means of communication. Though perhaps violent, it is usually very conclusive, which is why many animals have developed toxins they inject into potential predators to ward them off. Among these toxins are the well-known venom cocktails snakes, scorpions and spiders are able to conjure up. In answer to this, a few animals have developed mechanisms to ease the pain - or even suppress it altogether. This is the case of one species of mouse - the Southern grasshopper mouse from the Texan desert - who feels next to no pain when stung by the bark scorpion. As a consequence, the mouse is able to ignore the sting and eat the scorpion. Recent studies have demonstrated that this extraordinary ability is due to changes in the structure of a given type of pore: sodium channel protein type 10 subunit alpha, or Nav1.8.
