Here's a fun link to a piece by Jeff Houck of the Tampa Tribune. He pored through news archives to find 50 things we know now that we didn't know a year ago.

If he had gone through scientific journals he probably would have discovered stuff the news media missed altogether rather than stuff they simply downplayed or didn't feature.
It's hardly news to parents who have lived through those years that "The part of the brain that regulates reasoning, impulse control and judgment is still under construction during puberty and doesn't shift to autopilot until about age 25." Of course. But I'd like to know more about the "autopilot" phase. Does it suggest that after 25 people (or most people) stop reasoning originally or simply don't process new information that doesn't fit their preconceptions? I discover evidence for that hypothesis almost every day.
