Do we achieve what we achieve through force of will, or does fate have us by the throat? This hour, <em>Radiolab</em> explores the tug of war between will and fate from birth to death - from a kid reaching for a marshmallow to hints of dementia in the words of a 20-year-old.</p><p>For more information, visit <a href="http://www.radiolab.org/">http://www.radiolab.org/</a>.</p> Fri, 06 Apr 2012 16:00:00 +0000 NHPR Staff 2680 at http://nhpr.org Episode 805: Fate and Fortune Episode 804: Cities http://nhpr.org/post/episode-804-cities <p>Over 50% of the planet now lives in cities. This hour, <em>Radiolab</em> looks at what makes them tick. We talk to a couple physicists who think they can fit every city into a tidy mathematical formula, and we take to the streets to test their idea. We explore the water tunnels 700 feet below Manhattan and question whether cities are the source of, or the solution for, our growing global appetite.</p><p>For more information, visit <a href="http://www.radiolab.org/">http://www.radiolab.org/</a>.</p> Fri, 06 Apr 2012 15:59:00 +0000 NHPR Staff 2679 at http://nhpr.org Episode 804: Cities Episode 803: Falling http://nhpr.org/post/episode-803-falling <p>There are so many ways to fall - falling in love, falling asleep, even falling flat on your face.

Earth Has Just One Moon, Right? Think Again http://nhpr.org/post/earth-has-just-one-moon-right-think-again Everybody knows that there's just one moon orbiting the Earth. But a new study by an international team of astronomers concludes that everybody is dead wrong about that.<p>"At any time, there are one or two 1-meter diameter asteroids in orbit around the Earth," says <a href="http://www.ifa.hawaii.edu/users/jedicke/jedicke.html">Robert Jedicke</a>, an astronomer at the <a href="http://www.ifa.hawaii.edu/">Institute for Astronomy</a> at the University of Hawaii.<p>Since most of these objects are too small to see, Jedicke had to use indirect methods to reach his conclusions.

Next year, if all goes as planned, a rather different expedition will take place 1,000 miles south of that dive: An Australian company will start mining for copper, gold, silver and zinc on the seafloor off the shore of Papua New Guinea.<p>People have thought about mining the seafloor's mineral wealth for many decades.

So why wasn't the Earth frozen solid?<p>We know it wasn't because there's plenty of evidence for warm seas and flowing water way back then. The question is still puzzling scientists.<p>But new clues to that paradox come from an unlikely source: fossilized raindrops, from 2.7 billion years ago. Back then, the Earth had no trees or flowers or animals birds or fish. But it did have volcanoes.

Today, at the Lunar and Planetary Science Conference in Houston, astronomers revealed what they've learned about the innermost planet in our solar system, and some of the new knowledge is puzzling.<p>Maria Zuber, a planetary scientist at the Massachusetts Institute of Technology, studied a large crater 900 miles across called Caloris.<p>"The northern half of Caloris has actually been uplifted so that it's actually higher than its rim," she says.

F. Sherwood Rowland, Warned Of Aerosol's Danger http://nhpr.org/post/f-sherwood-rowland-warned-aerosols-danger The man who warned us that aerosol spray-cans could destroy the earth's protective ozone layer has died.<p>F. Sherwood Rowland, better known as Sherry Rowland, was a Nobel-prize winning chemist at the University of California, Irvine. And he didn't just keep to the laboratory: He successfully advocated for a ban on ozone-destroying chemicals called CFCs.<p>Rowland was a towering figure in several senses of the world. He was big, 6-foot-4, and had a commanding presence in any room. He spoke his mind with directness. And his thoughts were firmly grounded in science.
