Historic drought in the west and water diversion for human use are causing stretches of the Colorado and Mississippi rivers to run dry. "The American West is going to have to need to learn how to do more with less," says Laurence Smith, a river surveyor and environmental studies professor at Brown University. He recently dropped in for a chat with Short Wave co-host Emily Kwong about how scientists are turning a new page on managing two of The United States's central waterways, the Colorado and Mississippi Rivers.

With a narrow majority in the House, Republicans will need to find ways to work with Democrats — who still control the Senate and the White House. What battles may loom large for the new Congress?

As those battles are waged, one person will be on the front lines: New York Republican Elise Stefanik, who chairs the Republican conference. Her rise from a bipartisan member of Congress to a staunch defender of Donald Trump has drawn attention.

And, among the things we can't let go of this week? A certain royal's memoir.

This episode: White House correspondent Asma Khalid, congressional correspondent Claudia Grisales, political correspondent Susan Davis, and national correspondent Brian Mann.

This episode was produced by Elena Moore and Casey Morell. It was edited by Casey Morell. Our executive producer is Muthoni Muturi. Research and fact-checking by Devin Speak.

Are humans ever satisfied? Two social psychologists, Ethan Ludwin-Peery and Adam Mastroianni, fell down a research rabbit hole accidentally answering a version of this very question. After conducting several studies, the pair found that when asked how things could be different, people tend to give one kind of answer, regardless of how the question is asked or how good life felt when they were asked. Short Wave's Scientist in Residence Regina G. Barber digs into the research—and how it might reveal a fundamental law of psychology about human satisfaction.

Inside the mountaintop glaciers of the Pacific Northwest lives a mysterious, and often, overlooked creature. They're small, black, thread-like worms that wiggle through snow and ice. That's right, ice worms! Little is known about them. But one thing scientists are sure of? They can't really handle freezing temperatures. In this episode, NPR science correspondent Nell Greenfieldboyce talks to Emily about how ice worms survive in an extreme environment and why scientists don't understand some of the most basic facts about them.

There's always a moment of intense isolation when Jessica Mejía gets dropped off on the Greenland ice sheet for a multi-week research stint. "You know you're very much alone," said Jessica, a postdoctoral researcher in glaciology at the University of Buffalo. Glaciers such as those that cover Greenland are melting due to climate change, causing sea levels to rise. That we know. But these glaciers are also moving. What we don't know is just how these two processes – melting and movement – interact and ultimately impact how quickly sea levels will rise. Jessica Mejía, a postdoctoral researcher in glaciology at the University of Buffalo, joins Short Wave's Aaron Scott to explain what it's like to live on a glacier for a month, and what her research could mean for coastal communities all over the world.

How will things shake out before the next presidential campaigns start in earnest?
