Rex Treks To Washington For A Shot At Fame http://wnku.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 34603 at http://wnku.org A T.

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.

It led to large communities, monumental architecture and complex societies. It also led to tooth decay.<p>When hunter-gatherers started adding grains and starches to their diet, it brought about the "age of cavities." At least that's <a href="http://www.npr.org/blogs/health/2013/02/24/172688806/ancient-chompers-were-healthier-than-ours">what a lot of people thought</a>.

Who Will Pay? http://wnku.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>.

Centuries Before China's 'Great Wall,' There Was Another http://wnku.org/post/centuries-chinas-great-wall-there-was-another The Great Wall of China, built more than 2,000 years ago, stands as one of the monumental feats of ancient engineering. 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.

Just how many? Well, since 1965, researchers in Europe have been tracking the world's food supply and where it's going.<p>The good news is: The percentage of the world's population getting what the researchers say is a sufficient diet has grown from 30 percent to 61 percent.<p>In 1965, a majority of the world survived on less than 2,000 calories a day per person. This was especially true in parts of the Middle East, Africa, Latin America, China and Southeast Asia.

Its population was virtually wiped out in the lower 48 states. One group of bears, though, may soon lose that protection - the Yellowstone grizzly. Some scientists say that group is thriving. Others disagree. NPR's Christopher Joyce has more on the battle over the bear.<p>CHRISTOPHER JOYCE, BYLINE: The U.S. Fri, 13 Dec 2013 12:52:00 +0000 Christopher Joyce 30337 at http://wnku.org Long Island Wins Ultimate Faceoff Against Hurricane Sandy http://wnku.org/post/long-island-wins-ultimate-faceoff-against-hurricane-sandy Hurricane Sandy last year did more harm to coastal cities and homes than any hurricane in U.S. history, except Katrina. Most of that damage has been repaired. But there's other damage that people can't see to the underwater coastline, known as the shore face.<p>Apparently, Long Island's shore face did remarkably well against the storm of the 21st century.<p>The shore face is the underwater slope that runs up to the shore. Its shape influences how fast and high water moves onto land. Sandy pushed water up the shore face and into towns and bays.
