Not long ago, the red sandstone walls of the Dolores River Canyon in southwestern Colorado towered over roaring rapids that teemed with native fish.

Now, it's largely empty.

Drought compounded by climate change has left the once robust river a ribbon of cobblestones, a trickle of water and small, shallow pools.

"It's really an unfortunate and tragic, incredible canyon with sort of a meek river that was once really a giant, wonderful symbol of the Wild West," said Jim White, an aquatic biologist for Colorado Parks and Wildlife.

Last month, Pastor Danny Reeves was fighting for his life in the intensive care unit at Dallas' Baylor University Medical Center. He had COVID-19, and he wasn't vaccinated.

Now, the senior pastor at First Baptist Corsicana in north central Texas regrets not getting the shot earlier, and he plans to tell his congregants his story on Sunday when he returns to the pulpit.

"I was falsely and erroneously overconfident," Reeves told NPR's Debbie Elliott on Morning Edition.

The world of matchmaking won't have to rely on luck, as much as math, thanks to one very accomplished teenager.

Yunseo Choi, a senior at Phillips Exeter Academy in New Hampshire, came up with a matching theory that can be applied to people looking for a life partner.

Instead of matching a finite number of people, the 18-year-old figured out how to pair an infinite number of potential couples.

The idea being that when your options are infinite, your matched date will likely be better suited for you.
