International ships call at the busy Port of New Orleans. It's a major shipping convergence point on the Mississippi River. Ships come upriver from the Gulf of Mexico with imports from abroad, and barges come downriver, bringing U.S. goods for export.
Congress has now agreed to give some $60 billion to states damaged by Hurricane Sandy. A lot will go to Long Island, one of the hardest hit areas. Besides damages to homes and businesses, its system of protective barrier islands and beaches were partially washed away.
Scientists are trying to find out where that sand and sediment went, and whether it can be used to rebuild Long Island's defenses.
The battle between cat lovers and bird lovers has been going on for a long time. Cats and birds just don't mix. But trying to get a handle on how many birds and other animals are being killed by cats isn't easy. Just figuring out how many cats there are is tough enough.

Where does the mind fit within the cosmos? Are they separate, intertwined or one and the same?

So I want you to do something for me. I want you to think of a blue monkey. Are you ready? OK, go! Visualize it in your head. Any kind of monkey will do (as long as it's blue). Take a moment. Really, see the little blue dude! Got it? Great. Now, here is the question: Where did that thought fit into reality? How was it real? Where was it real?

The eye of Hurricane Earl in the Atlantic Ocean, seen from a NASA research aircraft on Aug. 30, 2010. This flight through the eyewall caught Earl just as it was intensifying from a Category 2 to a Category 4 hurricane. Researchers collected air samples on this flight from about 30,000 feet over both land and sea and close to 100 different species of bacteria.
Microbes are known to be able to thrive in extreme environments, from inside fiery volcanoes to down on the bottom of the ocean. Now scientists have found a surprising number of them living in storm clouds tens of thousands of feet above the Earth. And those airborne microbes could play a role in global climate.

Herding cattle up the side of a mountain might seem like a lot of extra work, but for thousands of years, people have hauled their cows into the Alps to graze during the summer months. Why? It's all about great-tasting cheese.
The Defense Department's Advanced Research Projects Agency, or DARPA, has incubated many important technologies over the decades in computer networking and other areas. The Energy Department wants to make similar strides with an agency called ARPA-E. Over three years now in operation, ARPA-E has spent nearly $800 million on 285 experimental projects.
We invited the agency's deputy director, Cheryl Martin, into our studio so we can find out more about these projects. Good morning.
