Rex Treks To Washington For A Shot At Fame http://wfae.org/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 49069 at http://wfae.org 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.

That's normal, because if you have too many, they'll eat themselves out of prey.<p>But top predators are now so rare that many are in danger of disappearing. That's creating ripple effects throughout the natural world that scientists are still trying to figure out.<p>What they're exploring is ecology — the interplay of animals and plants in nature. It's not rocket science.

Who Will Pay? http://wfae.org/post/federal-flood-insurance-program-drowning-debt-who-will-pay Millions of American property owners get flood insurance from the federal government, and a lot of them get a hefty discount. But over the past decade, the government has paid out huge amounts of money after floods, and the flood insurance program is deeply in the red.<p>Congress tried to fix that in 2012 by passing a law to raise insurance premiums. Now <em>that</em> move has created such uproar among property owners that Congress is trying to make the law it passed disappear.<p>Caught in the middle is the <a href="http://www.fema.gov/">Federal Emergency Management Agency</a>.

Florida's Mangroves Move North As Temperatures Rise http://wfae.org/post/floridas-mangroves-move-north-temperatures-rise Transcript <p>AUDIE CORNISH, HOST: <p>The world's climate is warmer on average than it was a hundred years ago. Plants in some places are emerging earlier in the spring and insects that like warm weather are on the move. But scientists are finding out that the culprit isn't just warmth. As NPR's Christopher Joyce reports, it's also the absence of cold snaps.<p>CHRISTOPHER JOYCE, BYLINE: The idea that a warmer planet could mean avocados in Scotland or bananas in Montana may sound silly. But in fact, tropical plants are moving north.

Stretching thousands of miles, it protected the newly unified country from foreign invaders.<p>But before the Great Wall, warring Chinese dynasties built many other walls for protection.
