What do large crowds of people and water have in common? They both act like fluids. When crowds cheer, sway and clump together, the movements look like ripples of water. Researchers hope insights from physics like this one could help officials and engineers create safer crowds at festivals.Help shape the future of Short Wave by taking our survey: npr.org/shortwavesurveyListen to every episode of Short Wave sponsor-free and support our work at NPR by signing up for Short Wave+ at plus.npr.org/shortwave.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Folge vom 05.02.2025Microbes: It's ComplicatedFor a long time, microbes like the ones in Yellowstone's hot springs were studied in isolation. Molecular ecologist Devaki Bhaya says we should be studying them in community.

Folge vom 04.02.2025Why Black Holes Are More Than They SeemBlack holes are notorious for gobbling up, well, everything. They're icons of destruction, ruthless voids, ambivalent abysses from which nothing can return — at least, according to pop culture. But black holes have another side: Astrophysicists have seen powerful jets, sometimes millions of light-years long, shooting out of supermassive black holes – including the one at the center of our own galaxy. So today, we're getting to know the other side of black holes, and the powerful role they may play in creating and shaping the cosmos.

Folge vom 03.02.2025Not All Nature Comebacks Are EqualEcologist Gergana Daskalova moved back to the small Bulgarian town of her childhood. It's a place many people have abandoned — and that's the very reason she returned. At the same time as land is being cleared around the world to make room for agriculture, elsewhere farmland is being abandoned for nature to reclaim. But what happens when people let the land return to nature? This episode, science reporter Dan Charles explains why abandoned land has conservationists and researchers asking: If we love nature, do we tend it or set it free?Read more of Dan's reporting for Science Magazine and NPR.Want us to cover other about ecology, biodiversity or land science stories?
