Sometimes the visible world is all we need to be astonished at this weird thing called reality. For example that big, warm, yellow ball makes it into the sky every day. And every year, somehow, Spring makes it back to us. (Hello Spring! Sooner rather than later would be nice.) But sometimes it's the invisible world that makes your head explode in wonder.
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.
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.
Now some years ago, road workers in the South American country of Chile discovered something big, really big - whale bones. And not just one or two of them, 40 giant skeletons including those of adult whales cradled together with juveniles. Scientists were called in, including my guest, Nick Pyenson.
Nick is the curator of Fossil Marine Mammals at the Smithsonian. He has to look after these things there. And this past week, he and his colleagues released their most comprehensive review yet of the site in Chile.
Ken Ham, the founder of the Creation Museum who last month debated TV personality Bill Nye "The Science Guy" pitting his Biblical literalism against Darwinian evolution, says the highly publicized showdown has been like manna from heaven for a foundering $73 million Noah's Ark theme park.
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.
