There's more to Yellowstone National Park than meets the eye. Much more, as it turns out.

You might already know that a supervolcano dominates the famous park that is situated on land in Wyoming and Montana. A shallow subsurface magma chamber has long been known.

It's springtime in Pittsburgh, and throughout the city, Callery pear trees are sprouting beautiful, white blossoms.

But that's just the problem. Simply put, these trees stink.

"This whole place smells like dead fish," says Sheila Titus. "I mean everywhere. Everywhere you see one of these trees with the white on them."

Titus has lived in her home in the now-hip neighborhood of Lawrenceville for 49 years. Two decades ago, her grandson and his 7th grade class planted a row of Callery pears across the street from her house.

Why Don't Ants Need A Leader?

The world's largest ant colony stretches over 3,700 miles. It succeeds, biologist Deborah Gordon says, because no one is in charge. The ants communicate with algorithmic patterns to survive and thrive.

Most of the world’s rice production occurs oceans away from the United States. In 2011, molecular biologist Michael Schläppi dove into rice research hoping to grow the grain in Wisconsin.

According Schläppi, 80 percent of the rice Americans consume is grown in a handful of states, especially Arkansas and California. “But I think it would be wise to think about, with climate change or the drought in California, maybe they won’t be able to grow rice anymore,” he says.

Bay View resident Jesse Blom wants to be part of the solution. That means a bit of experimentation and a lot of learning.

Blom helped transform an 1898 Queen Anne Style home on Euclid Ave in Bay View to Heart Haus, created to demonstrate sustainable urban community.

Not only do vegetable patches fill its front and backyard, greens are growing off the kitchen.

A magnitude-3.0 earthquake is small, but most people can feel it. Historically, Oklahoma got less than two of those a year, but in 2013 it became two a week.

It's only gotten more active since then — last year, the state had three times as many earthquakes as in the entire seismically active state of California.

Fruit growers in northern Michigan grow apples, peaches and wine grapes. But the big crop here is tart cherries.

More than half of Ken Engle's 140-acre farm is planted with what he calls sour cherries.

President Obama used the backdrop of the Florida Everglades this Earth Day to highlight the dangers posed by a changing climate. He also took a swipe at Florida's Republican governor, who's been accused of discouraging state workers from discussing global warming.

"Climate change can no longer be denied," Obama said. "It can't be edited out. It can't be omitted from the conversation. And action can no longer be delayed."

It has been about a decade since beekeepers and scientists began documenting a decline in honeybee populations and other important pollinators.

Even if you're not a lover of bees or honey, you should know that bees are critically important to our food supply. They help pollinate billions of dollars of crops each year, from apples and carrots to blueberries and almonds.

So if bees are threatened, ultimately, the production of these crops will be threatened, too.
