Since 2005, the number of wild and domesticated birds killed is greater than the combined human populations of the United States and Russia. Bir

The idea that the universe is made of tiny vibrating strings was once the science theory du jour. String theory promised to unite the disparate theories describing particles and gravity, and many people, not just scientists, were optimistic that a theory of everything might be within our grasp. But here we are, many ye

“The Mississippi River will always have its own way; no engineering skill can persuade it to do otherwise,” said Mark Twain. In this, our final episode marking the 20th anniversary of Hurricane Katrina, we consider how efforts to control the Mighty Mississippi – a river engineered from its Minnesota headwaters to its G

What happens to us after we die is as much a question for anthropology and ecology as it is for theology.  Death and decay are not comfortable subjects, but some scientists study them unflinchingly, knowing that doing so yields valuable scientific insights about decomposition. We hear about The Body Farm at the Univers

Shipwrecks are scenes of tragedy, but they are also bits of history frozen in time that can provide insights into events and ideas from long ago. That is, if we can find them.  From an 11th century Viking sailing ship to a WW II era British cargo ship with a mailbag of letters onboard amazingly preserved, an underwater
