Map of America http://kttz.org/post/who-do-you-hang-map-america 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 The Big Squeeze: Can Cities Save The Earth? http://kttz.org/post/big-squeeze-can-cities-save-earth Let's get dense. If we take all the atoms inside you, all roughly 70,000,000,000,000,000,000,000,000,000 of them, and squeeze away all the space inside, then, <a href="https://twitter.com/bgreene/status/320173198178136066">says physicist Brian Greene</a>:<strong></strong><p>That's a very tight fit. So tight that in real life, it couldn't happen. It's not physically possible. Atoms won't crunch that close. But people, it seems, are willing to try.

This year's flu is called "H3N2" and this week it's doing big business in about 47 states, Chicago and New York. If you've had a flu shot and if you wash your hands several times a day for 20 seconds, (which is the time it takes to hum "Happy Birthday to You" two times through) you might reduce your odds of getting sick.<p>But your biggest ally is your immune system. It's hard, during flu season, to avoid inhaling a virus or two (or three, or 10,000), but that doesn't mean they're going to take you over.

You can find it at the bottom of this page. </em><p>Look at yourself. Right now.<p>You are muscle,skin, bone, brain, blood, warmed by energy, and all of you, every cell, even the subsets of those cells, all trillions and trillions of them, are going to tire, waste and depart. In 10 years almost every bit of you will have been replaced by new bits.<p>And yet, you will still be you.

This week, we've got ourselves a role model, a poster boy for robust old age.<p>Actually, it's a poster tree: <em>Sequoiadendron giganteum</em>, the giant sequoia. And thanks to <a href="http://www.humboldt.edu/redwoods/sillett/">Professor Steve Sillett</a> and his team at Humboldt State University, here's what we now know: these trees do more growing when they're older than when they're younger.
