Drought Causes Ripple Effect Along Mighty Mississippi River

Originally published on Wed January 30, 2013 8:30 pm

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.
Debbie Elliott NPR

The persistent drought is raising questions about how the Mississippi River is managed — both upstream and down.

While cargo traffic upriver has gotten lots of attention, the drought is creating a different set of problems downriver at the mouth of the Mississippi, where saltwater has encroached.

An old-fashioned staff river gauge behind the New Orleans district office of the U.S. Army Corps of Engineers shows the Mississippi is running just shy of 6 feet above sea level at the river bend.

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.

In January. On a boat in Long Island Bay.

MELISSA BLOCK, HOST:

From NPR News, this is ALL THINGS CONSIDERED. I'm Melissa Block.

AUDIE CORNISH, HOST:

And I'm Audie Cornish. And we have a story now about celestial navigation - that is, looking to the sky for guidance.

BLOCK: But before we get too lofty, this story also happens to be about dung beetles. And so we start with this lowly central unpleasant fact about dung beetles.

ERIC WARRANT: Dung beetles and their grubs eat dung and everything about dung beetles has to do with dung in some form.

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.

Is There A Place For The Mind In Physics? Part I

Originally published on Sat February 23, 2013 11:30 am

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

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?

Bird, Plane, Bacteria? Microbes Thrive In Storm Clouds

Originally published on Tue January 29, 2013 8:36 am

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.
Jane Peterson NASA

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.

How Mountain Grass Makes The Cheese Stand Alone

Cows graze in front of the Rosengarten mountain massif in northern Italy. Pasture grazing is practiced throughout the Alps.
Matthias Schrader Associated Press

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.

In places like Italy, some traditional cheeses, like bra d'alpeggio or Formai de Mut dell'Alta Valle Brembana, can only be made with milk from mountainside-munching cows.

Be Like A Bat? Sound Can Show You The Way

Echolocation is second nature to animals such as bats and dolphins. Can humans also find their way using sound as a tool?
Ian Waldie Getty Images

In 1974, the philosopher Thomas Nagel wrote a classic paper in which he asked, "What is it like to be a bat?" Nagel's choice of a bat was especially apt for making the point that some kinds of knowledge are bound by our own experience.

In a moment, there's going to be singing. It will be a love song, sung by Nathaniel, a sad-eyed, blue-gloved scientist who gave his heart to an organism, but then did her wrong. (Or maybe she did him wrong. These things get complicated.)
