Rex Treks To Washington For A Shot At Fame http://wuwm.com/post/t-rex-reveal-itself-smithsonian This week, scientists at the Smithsonian's National Museum of Natural History will start unpacking some rare and precious cargo. It's something the Smithsonian has never had before — a nearly complete skeleton of a Tyrannosaurus rex.<p>Most people don't know it, but the T. rex that's standing tall in the Natural History Museum in Washington, D.C., is a fake — a cast, a copy of the bones. It's an accurate replica, but for decades the Smithsonian has coveted a real skeleton of a T. Wed, 16 Apr 2014 07:43:00 +0000 Christopher Joyce 29257 at http://wuwm.com A T.

I'm Steve Inskeep.<p>DAVID GREENE, HOST: <p>And I'm David Greene. Good morning. The biggest extinction the Earth has ever seen took place 250 million years ago and it remains something of a mystery. Scientists suspected giant volcanoes or perhaps an asteroid caused it, but NPR's Christopher Joyce has seen new research suggesting the cause might not have been so cataclysmic - maybe something much more subtle.<p>CHRISTOPHER JOYCE, BYLINE: It's sometimes called the Great Dying.

It's called <a href="http://penguinstudies.org/">Punta Tombo</a>. Dee Boersma, a conservation biologist at the University of Washington, has been going there for 30 years, and she's discovered that a changing climate is killing those penguins.<p>I <a href="http://www.npr.org/templates/story/story.php?storyId=1315147">visited</a> Boersma in 2003 for NPR's Radio Expeditions program. She literally lived amid the colony, the world's largest group of Magellanic penguins.

It dates back to the late 18th century. Despite frequent face-lifts, parts of it are wearing out — for example, its underground gas pipelines. New research shows that Washington, D.C., suffers from thousands of leaks of natural gas.<p>"We drove 1,500 road miles in Washington, D.C., and found about 6,000 leaks," says <a href="http://biology.duke.edu/jackson/">Robert Jackson</a>, an ecologist and environmental scientist at Duke University.
