A bee-buzzing, honey-licking 2,000-year-old mystery that begins here, with this beehive. Look at the honeycomb in the photo and ask yourself: (I know you've been wondering this all your life, but have been too shy to ask out loud ... ) Why is every cell in this honeycomb a hexagon?<p>Bees, after all, could build honeycombs from rectangles or squares or triangles ...<p>But for some reason, bees choose hexagons. <em>Always </em>hexagons.<p>And not just your basic six-sided hexagon.

Map Of America http://news.stlpublicradio.org/post/where-do-missouris-dollars-and-callers-hang-out-maps-americas-neighborhoods Look at the center of this map, at the little red dot that marks Kansas City. Technically, Kansas City is at the edge of Missouri, but here on this map it's in the upper middle section of a bigger space with strong blue borders. We don't have a name for this bigger space yet, but soon we will.<p>I would call it, for the moment, "The Part Of America Kansas City Hangs With" because that's what this map is saying. It's a new, intriguing way to see our country. This one was built by tracking dollar bill circulation. There've been similar maps built from phone call data.

Map Of America 'No, Thank You': The Mysterious Transformation Of 50-Year-Olds http://news.stlpublicradio.org/post/no-thank-you-mysterious-transformation-50-year-olds Harry Dent, <a href="http://en.wikipedia.org/wiki/Harry_Dent">a financial newsletter writer</a>, has been looking at the Census data, and he's uncovered something odd about American adults. When we turn 50, we dramatically change our clothes-buying habits. It's not gradual; gradual is what we'd expect. Instead, the change is drastic.<p>You can see it with men's shirts. In our early 50s, American men are at the top of our shirt buying game (either buying more shirts than at any other time in our lives, or maybe we're buying more expensively).

These are the counties that went for Obama in the last election. A blue crescent in a sea of red.<p>These same counties went mostly blue in 2004 and 2000. Why? Well, the best answer, says marine biologist Craig McClain, may be an old one, going back before the Civil War, before 1776, before Columbus, back more than 100 million years to the days when the Deep South was under water.
