These days you can fly to far corners of the world and eat pretty much the same food you can get back home. There's pizza in China and sushi in Ethiopia.

A new scientific study shows that something similar is true of the crops that farmers grow. Increasingly, there's a standard global diet, and the human race is depending more and more on a handful of major crops for much of its food.

Ah, cows. They're big, lumbering, earthbound beasts, right? But sometimes, Bessie and pals just have to get airborne.

That gif of dairy cows "jumping for joy" is from a video that's been making the rounds on the Internet. We spotted it last week when food journalist Michael Pollan tweeted it out:

Even In A Desert, Drought Spells Trouble For Ranchers

No snowpack, no hay: In the northern Nevada, cattle feed is getting hard to come by, as sources of water diminish in supply.

In northern Nevada, a place famous for its wide, open spaces and expansive cattle operations, ranchers are in a bind due to the historic drought.

Much of the state is desert, so when people talk about drought, they're really talking about the snowpack in the Sierra Nevada. It's at barely 20 percent of average.

This is a huge concern for farmers and ranchers like Julie Wolf, because the mountains store the snow that melts and feeds rivers and reservoirs. These bodies of water then allow the desert to bloom with grass and alfalfa for her cattle.

JACKI LYDEN, HOST:

Now some years ago, road workers in the South American country of Chile discovered something big, really big - whale bones.

A Pelican Shows Us What It's Like To Fly

Pelicans have the life. They live by the water, fly over the ocean, and eat lots of fish. Among humans, only T.C. from Magnum P.I. comes close to matching them. And he's just a fictional character, played by Roger E. Mosley.

The Limits Of Simulation

The idea that the world might be living in a simulation — discussed in Marcelo's post this week — is brought to life with wit and power in Peter Weir's 1998 film The Truman Show.

A Strong Sex Life Helps Couples Cope With The Trials Of Aging

Originally published on Mon March 3, 2014 7:32 am

Intimacy in a marriage becomes even more important as we get older.

Health problems can put a strain on a marriage at any age. But as we get older, chronic illnesses can make it even tougher to keep the spark alive.

Scientists at the University of Chicago have uncovered one way couples can offset the stresses of illness and aging: more physical intimacy.

Couples who continue to be sexually active over the years report higher levels of satisfaction in their marriages, the sociologists reported last month.
