If you're not great at doing math in your head, you're in pretty good company around these parts. In general, too -- an estimated 20% of otherwise healthy adults regularly struggle to do basic arithmetic without showing their work. Don't give up hope, though! A new treatment being studied at Oxford University could make you better at doing math in your head for up to six months at a time -- and all you have to do is put on what looks like a steampunk gimp mask and let someone deliver electrical shocks to your brain!
We've all had the experience of playing a game of Temple Run or Angry Birds and thinking "Yeah, this is fun and all, but I really with this game would deliver a mild electrical shock through my phone." Soon, you may get the chance to turn that fantasy into reality thanks to the work of computer interaction researcher Pedro Lopes, who has developed a new control interface for playing games on your phone -- one that uses electrodes to shock players.
