In The Colorado River, These Little Suckers Are Making A Comeback

The temperature is hovering right around 90 degrees the day Dale Ryden and I float down the Colorado River near Grand Junction, Colorado. The water looks so inviting, a cool reprieve from the heat, but if either of us jumped in we’d be electrocuted. “It can actually probably be lethal to people if you get in there,” Ryden, a fish biologist with the U.S. Fish and Wildlife Service, says.

Some of the weirdest animal behavior is about romance. That's especially true with birds — they croon or dance or display brilliant feathers to seduce the reluctant.

This sort of sexual display apparently has a long pedigree: There's now new evidence that some dinosaurs may have used the same come-on.

The source is a kind of dinosaur that was built like a 400-pound ostrich. It lived about 75 million years ago and is called ornithomimus, meaning "bird mimic."

Democrats and Republicans are on track to spend about $1 billion each on television advertising in the presidential race. Most of it is negative, and almost all of it is concentrated in nine battleground states.

If you live in Colorado, Florida, Iowa, Nevada, New Hampshire, North Carolina, Ohio, Virginia or Wisconsin, you cannot get away from the ad blitz being waged by both sides. For the folks who track political advertising at Kantar Media CMAG, these commercials tell a story.

Just about every president since Richard Nixon has set energy independence as a goal, and both major candidates have brought it up the current campaign.

As it turns out, there is a place, not so far from here, that has achieved energy independence: Canada.

Canada produces far more oil than it consumes. They're not dependent on the Middle East! They've got all the oil they need!

I called Stephen Gordon, a professor of economics at Université Laval in Quebec City, to ask him about what energy independence means for his nation.

When Marcela Gaviria was 7 years old, she was diagnosed with Ewing's sarcoma, a type of childhood bone cancer. She survived, and the cancer was cured — but it nearly took her leg.

When Gaviria was 12, she needed a bone transplant and met surgeon Dempsey Springfield, who performed the operation.

"I was pretty scared, I remember, and I think I survived a very sort of traumatic moment 'cause you were so kind," Gaviria, now 43, told Springfield at StoryCorps in Boston.
