I'm not a pub quiz master - facts often slip my mind. Would a bigger brain help me? It sounds a bit like Frankenstein's monster, but scientists have boosted brain tissue growth in frog embryos using electricity.
They tweaked natural electric currents in the brain tissue of growing frogs and encouraged more brain matter to develop. It's unlikely to be used on people any time soon, but it's a new way to control how tissue grows. It could be used to change the size of other body parts as they develop. I wonder what they'll try next?
