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.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Folge vom 12.01.2023Behold! The Mysterious Ice WormInside 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.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Folge vom 11.01.2023How Glaciers MoveThere'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.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Folge vom 10.01.2023Zircon: The Keeper Of Earth's TimeThe mineral zircon is the oldest known piece of Earth existing on the surface today. The oldest bits date back as far as 4.37 billion years — not too far from the age of Earth itself at about 4.5 billion years old. And, unlike other minerals, zircon is hard to get rid of. This resilience enables scientists to use zircon to determine when major geological events on Earth happened. As part of our series on time, host Aaron Scott talks to science correspondent Nell Greenfieldboyce about why this mineral is often considered a geologic clock and has earned the nickname "Time Lord." This episode is part of our series, "Finding Time — a journey through the fourth dimension to learn what makes us tick." Read more of Nell's reporting on zircon here.
