...some men were worse than others at avoiding the ones that resulted in sad faces. Those men, it turns out, had a particular gene variant, or allele, that reduces the density of receptors for dopamine - a neurotransmitter that plays a key role in motivation, pleasure and addiction - in certain areas of the brain. Brain scans also showed significantly less activity in those areas in response to the sad-faced negative feedback, in the men who had the allele. When it occurred, however, that brain activity was linked to activity in other parts of the brain that forms memories...
...paper highlights what researchers don't yet know: the interplay of genes, dopamine and the process of learning is still mostly a mystery, and researchers are hesitant to guess how this particular genotype really affects any given individual - or that having it would even be a bad thing. "Under certain circumstances it might be positive [for a person] to ignore negative feedback and to persevere," says Ullsperger. Soldiering on in the face of setbacks, after all, is a key ingredient for success. In the end, these new findings may well be one of many steps toward piecing together the puzzle...

This much is certain: no candidate in either party has done more with less this year. Lacking Mitt Romney's money, Rudy Giuliani's name recognition and John McCain's chest full of medals, Huckabee has leveraged his opportunities like Archimedes on a good day. His steady, good-humored performances in televised debates gradually lifted him out of the second tier and helped smother his main rival for evangelical affections, Sam Brownback of Kansas. Meanwhile, Huckabee has never lost sight of the core fact of the Iowa caucuses: turnout is minuscule. Because of inconvenient scheduling (on a school night...
...matchup it’s clear what kind of competition David presents. But in this realm, inexperienced fencers do not move in the same ways seasoned veterans do. “It’s always hard to adjust to beginners because you expect them to react in a certain way and then they don’t react,” co-captain Samantha Parker said. “It’s a different sort of game you’re playing then. You’re not preparing your actions in the same way. It?...
