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?

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.)

Energy Department Encourages New Energy Technology

Originally published on Mon January 28, 2013 10:11 am

RENEE MONTAGNE, HOST:

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.

CHERYL MARTIN: Good morning.

Mention the recent surge in oil and natural gas production in the U.S. and one word comes to mind for a lot of people: "fracking." Hydraulic fracturing is a controversial technique that uses water, sand and potentially hazardous chemicals to break up rock deep underground to release oil and natural gas.

But there's another technology that is just as responsible for drilling booms happening across the country: horizontal drilling.

Seeing U.S. Laboratory Chimpanzees For Who They Are

Originally published on Mon January 28, 2013 8:59 am

By now, you probably know that the National Institutes of Health last week announced its plans to retire to sanctuaries hundreds of chimpanzees used for research, including invasive biomedical research. The story was big news nationally, including here at NPR, and resulted also in posts by animal advocacy groups such as PETA.

Weekend Special: The Slobbering Cat That Stole My Heart

Courtesy of The Oatmeal

Maybe you already know about this, maybe I'm in love, maybe this is just me and my particular craziness, but I want you to click on the image below. It's Mathew Inman's (who calls himself "The Oatmeal") story, handwritten, hand drawn, about his cat, Domino.

There are, we all know, wonderful sites all over the web, but every so often somebody comes along and rejuggles words, pictures and plays with space, remixing elements to very quietly find new beats, new ways to tell a story. That is what Mathew did here. At least I think so.

In Arizona, Some Retirees Caught In Never-Ending Battle With Invasive Species

Transcript

MELISSA BLOCK, HOST:

We go now to Arizona, a magnet for retirees, and for some the answer to the question how should I spend my spare time is this: How about swinging a pick axe in the desert? NPR's Ted Robbins sent this postcard from Ironwood Forest National Monument.

TED ROBBINS, BYLINE: This must be Gary Borax's idea of a good time because he keeps coming back.

GARY BORAX: I've probably been out here 30, 40 times over the years and nearly half of those buffel grass-related.

The Book Club Catches 'The Andromeda Strain'

Transcript

IRA FLATOW, HOST:

It's that time again, the SCIENCE FRIDAY Book Club. Regulars are gathered here. With me are Flora Lichtman, correspondent and managing editor of video for SCIENCE FRIDAY, Annette Heist, our senior producer. And this month, we had a page-turner, "The Andromeda Strain."

FLORA LICHTMAN, BYLINE: Yes.

FLATOW: It goes very quickly, that book, doesn't it? Poof.

LICHTMAN: It did. I was thinking of 300 and something-odd pages, but I, you know, in one sitting, was halfway through. I couldn't put it down.
