When I moved to New York City last summer, one of the first things I noticed was the fervor with which East Coasters are trying to stomp out invasive spotted lanternflies. These bugs were detected in the United States in 2014, and made their way to New York during the pandemic. As this invasive species’ range continues expanding, they’re causing agricultural damage — according to a worst-case scenario estimate from the New York’s Department of Agriculture and Markets, the spotted lanternfly could cost the state up to $300 million dollars each year. To this day, they’ve been at the center of widespread media campaigns urging people to stomp them out. I wanted to know where this whole stomping idea came from, and how New York got to this point. I also couldn't help but wonder — have we been talking about spotted lanternfly all wrong? IMAGE: A spotted lanternfly perches on a branch.

In 2020, the National Park Service announced the closure of Dead Horse Bay, a section of water and shoreline within the Gateway National Recreation Area in Brooklyn. Survey results had shown radiological and chemical contamination at the popular beachcombing spot, and the park service said that a federal cleanup effort would follow. More than five years later, the closure is still active, the paths are overgrown and the beach appears to be untouched. Here's a look at what's happening — or not — down at Dead Horse Bay.

Hannah Chiu might only be a medical student at Tulane University, but she is using her platform to make sure young menstruators know everything from how to use a tampon to birth control options. With only 29 states mandating any form of sex education, Chiu joins the many people around the country looking to teach about menstrual periods, a topic that is not federally required to be taught in sex education curricula and often goes overlooked. From Trish Hutchinson taking up-and-coming doctors into the classroom, to Andrew Lupo, a pediatric gynecologist, teaching his patients firsthand, discover the ways menstruation education is reaching young people when they need it most. UPDATE FROM OCTOBER 2025 TAPING: Period Prepared is a menstruation education program co-founded by Hannah Chiu and Olivia French, both medical students in New Orleans, and their mentor, Dr. Stephanie Shea. The interview features Hannah Chiu and reflects the work of the organization as a whole. As of February 2026, Chiu is still working within the menstrual education space, but is not using Period Prepared branding.

Lots of research has tried to break down how music toys with the emotions of any audience, but have you ever thought about how music makes the musicians playing it feel? A group of researchers from Italy recently noticed this gap in the science and decided to answer it. They found that when violinists play more emotional pieces, their bow movements are rougher. Nicola di Stefano, the cognitive scientist who led the study, thinks that this effect might come from musicians reacting strongly to the emotions in the pieces they play. He suggests that psychological pressure is the root cause. Professional violinist Curtis Macomber, though, doesn't see these results echoed in reality. He thinks of emotion as an overwhelmingly positive tool in his arsenal, something that makes his playing better, rather than worse. While Nicola and his team found that emotions can hamper a violinist, Curt actually looks forward to encountering them. Listen in as we dive into how playing emotional pieces affects musicians.

Have you ever wanted to take a trip to the Arctic? Every year, tourists from around the world make their way to the region. But the ships carrying these tourists bring an invisible pollutant with them — one that’s impossible to see and impossible to ignore: noise. How does this unseen phenomenon affect animals that call the Arctic home? And what role do even the most environmentally conscious travelers play in this story? Researchers and cruise industry officials are working to uncover the answers. Join us as we dive into this noisy crisis and hear from the experts navigating its challenges — and exploring ways to protect the Arctic’s pristine, icy wilderness.

It’s no secret that rivers winding through major cities have been reshaped by human hands. Where wildlife and marshes once existed, gray sidewalks and bleak straight-lined tributaries have blossomed. Now, some cities are implementing floating wetlands — native plant life on a body of biodegradable materials that bobs on top of the water — to address a budding desire to see animals and greenery return to their rivers.  In this podcast episode, Jenaye Johnson speaks with scientists and community members in Chicago about the Wild Mile — the city's biggest floating wetland to date. Join her as she winds down the Chicago River, explores the wetlands and discusses the future of new animal habitats and clean water in our urban spaces.

Meet the newest robotic police officer in town: the Knightscope K5. This “Robocop” completed a two month trial period in New York City’s Times Square subway station from September to November of 2023, recording video and monitoring the station. But despite city officials promising its safety, people were understandably nervous about a robotic police officer.  The robot’s trial period has ended and the K5 will not be re-entering the subway system, but it still serves as an important window to the future of robots integrating into our society.  In this podcast Kohava Mendelsohn talks to experts, does some research and even ventures forth to visit the K5 herself in order to answer the important questions: What was this robotic cop? What could it actually do? And how worried should we be about it?

Boredom under COVID quarantine led many to pursue some strange side hobby, but for 24 mathematicians and artists, it resulted in Mathemalchemy — a collective of mathematically (aesthetically, too) charming pieces of art — from cryptographic quilts, huge parabolas of embroidered spheres, crochet theta curves caught in fishing nets, and murals of OctoPi, seen generating various wave-related equations per every water ripple. For the “Mathemalchemists,” their project is a lively, whimsical invitation into the world of mathematics, made for an audience of all ages and interests. The goal is to illustrate how math can be fun — not something schools force you to do, but something that leaves you inspired. So, how did this project come to be? What makes Mathemalchemy so special, both for the Mathemalchemists and anyone that comes across the exhibition? In this podcast, Gayoung Lee goes behind the scenes of Mathemalchemy with co-founders Ingrid Daubechies and Dominique Ehrmann, in addition to Mathemalchemists Jessica Sklar, Elizabeth Paley and Carolyn Yackel.

Oysters have been a New York City culinary staple for centuries. Hundreds of years ago, when the Indigenous Lenape people lived in the region prior to European colonization, the harbor teemed with shellfish. But by the early 20th century, pollution, urban development and overharvesting erased nearly 350 square miles of oyster beds. Fast forward to the present, and a nonprofit is now working to revive the once-mighty bivalve. The Billion Oyster Project started seeding the harbor with oysters in 2010 to improve water quality, increase marine biodiversity and boost shoreline protection. Its efforts have been successful: The group is on track to meet its one-billion oyster goal by 2035. In October, Timmy Broderick spent an afternoon measuring oysters with other New Yorkers to learn more about the project and the harbor’s marine life.

When you imagine a dam, what comes to mind? Maybe it’s the hulking concrete wall of the Hoover Dam on the Colorado River or the Grand Coulee on the Columbia. Large barriers on large rivers, looming large on the horizon. But colossal structures like these make up only a fraction of the dams that chop up waterways across the United States. The nation’s rivers, streams and brooks are full of smaller dams — many of which aren’t monitored at the state or national level. And even though they’re small, these barriers can alter aquatic habitats and cause trouble for the species that live there. In this podcast, Madison Goldberg speaks with scientists about the issue and goes on a dam hunt of her own.

Growing up in Houston, Marina Watowich was no stranger to hurricane seasons. This familiarity now drives Watowich’s research in genomics, where she seeks to understand how the environment affects the aging process. She isn’t studying aging in humans — but in a unique population of monkeys in Puerto Rico. These monkeys live on an isolated island off Puerto Rico and give researchers unique access and insights into monkey genetics. In 2017, Hurricane Maria walloped Puerto Rico and tore down trees on the island where the monkeys live. After the storm, Watowich and colleagues discovered the primate survivors aged rapidly, findings that have implications for human aging after natural disasters. Scienceline reporter Hannah Loss speaks with Watowich on her journey to uncover the aftermath of hurricanes on aging.
