Don't Lighten Up

A canopy of stars in the night sky is more than breathtaking. Starlight is also an important tool that astronomers use to study our universe. But the growth of artificial light and light pollution are creating dramatic changes to the nighttime environment. Let your eyes adjust to the dark as we travel to a dark sky reserve to gaze upon an increasingly rare view of the Milky Way and explore what we lose when darkness disappears. Guests: Kim Arcand – Visualization scientist & emerging tech lead, NASA's Chandra X-ray Observatory and author of “Light: The Visible Spectrum and Beyond". Don Jolley – Teacher of Math and Sciences at the Bolinas School in Marin, California who has been leading dark sky tours for three decades. Christopher Kyba – Interdisciplinary Geographic Information Sciences Research Fellow at Ruhr University Bochum.

Katrina and the River

“The Mississippi River will always have its own way; no engineering skill can persuade it to do otherwise,” said Mark Twain. In this, our final episode marking the 20th anniversary of Hurricane Katrina, we consider how efforts to control the Mighty Mississippi – a river engineered from its Minnesota headwaters to its Gulf Coast outlet – have responded to the devastating storm, and how New Orleans’ relationship to the river has changed. Can the city keep up with the pressure that climate change is putting on this engineered system, or is retreat the only viable response? Plus, a wetland recovery project that aims to bolster protection from hurricanes and flooding in the Lower Ninth Ward. Guests: Boyce Upholt – Journalist and author of “The Great River: The Making and Unmaking of the Mississippi River” Nathaniel Rich – Author of “Second Nature: Scenes From a World Remade” and the New York Times Op-Ed, “New Orleans’ Striking Advantage in the Age of Climate Change” Harriet Swift – New Orleans resident Andrew Horowitz – Historian, University of Connecticut, author of "Katrina: A History, 1915-2015" Rashida Ferdinand – Founder and Executive Director of Sankofa Community Development Corporation, overseeing the Sankofa Wetland Park and Nature Trail in New Orleans Jason Day – Biologist, wetland Scientist, Comite Resources in Louisiana Featuring music by Dewey Dellay and Jun Miyake You can get early access to ad-free versions of every episode by joining us on Patreon.

Beyond the Standard Model

Ever heard of a beauty quark? How about a glueball? Physics is full of weird particles that leave many of us scratching our heads. But these tiny particles make up everything in the quantum world and in us and are the basis of the fundamental scientific theory called The Standard Model. But it doesn’t explain everything. It can’t account for dark matter or dark energy, for example. We find out whether new physics experiments might force us to rewrite the Standard Model. Plus, we discuss a NASA proposal to fly spacecraft close to the sun in search of new physics. Guests: Phil Plait – Aka the Bad Astronomer, former astronomer on Hubble, teacher, lecturer and debunker of conspiracy theories. He is also the author of a new book “Under Alien Skies: A Sightseer’s Guide to the Universe.” Harry Cliff – Particle physicist at the University of Cambridge who works on the LHCb experiment at the largest particle physics laboratory in the world, CERN. He is the author of: “Space Oddities, The Mysterious Anomalies Challenging Our Understanding of the Universe.” Slava Turyshev – Research scientist at NASA’s Jet Propulsion Laboratory.

Scoping Out the Universe

Telescopes are like light buckets. The bigger the telescope, the more light collected for astronomers to observe. With recent advances in technology, amateur astronomers can join professionals for a chance to observe stellar nurseries and exoplanets many light-years away. But as our capabilities increase, so do the mysteries, including those around high-energy bursts coming from an otherwise unremarkable part of the universe. Understanding fast radio bursts could turn physics on its head. From the Vera Rubin Telescope in Chile to the backyard instruments of amateur astronomers, we share what new things we might learn about stars, the Earth, exoplanets, and the potential for life on other worlds. Guests: Clare Higgs – Astronomer working with the public outreach team for the Vera Rubin Observatory Franck Marchis – Senior astronomer and director of citizen science at the SETI Institute, chief science officer and co-founder of Unistellar Amanda Cook – Postdoctoral fellow at McGill University and member of the CHIME/FRB Collaboration Featuring music by Dewey Dellay and Jun Miyake You can get early access to ad-free versions of every episode by joining us on Patreon.

Leave it to Beavers

They are known for holding branches in their paws and gnawing on them like corn cobs. They build lodges and dams which occasionally flood roads. Cute, comical, and considered pests, beavers were nearly hunted to extinction for their pelts before conservation efforts allowed their populations to rebound. Now environmentalists and engineers are reintroducing North America’s largest rodent to drought-prone habitats across the country. As the paddle-tailed animals’ dam-building has revealed itself to be a potent bulwark against climate change-induced water scarcity, the beaver is being hailed as an ecological hero. Join us as we stomp through soggy meadows getting to know the OG geoengineers. From their water pressure-sensing tails to their intricate branch-weaving, find out why, as our nation’s wetlands disappear, and new federal policies strip protection for many of those that remain, many think that partnership with a wild species could help build ecological resiliency. Guests: Leila Philip – Journalist and author of “Beaverland: How One Weird Rodent Made America” Denise Burchsted – research scientist, and engineer, Keene State College Clay Frazer – restoration ecologist with Native Range Ecological Michael Waasegiizhig Price – traditional ecological knowledge specialist at the Great Lakes Indian Fish and Wildlife Commission. He is Anishinaabe and a longtime tribal college educator serving at Leech Lake Tribal College and White Earth Tribal and Community College.

The Play's the Thing

Has children’s play become too safe? Research suggests that efforts to prioritize safety harms children’s mental and physical development during play and contribute to anxiety. One solution: introduce risk into play. We visit an adventure playground where kids play unsupervised with anything from scraps of metal to hammers and nails. Plus, what are the evolutionary benefits of play? After all, we’re not the only species who like to roughhouse, sled, or chase balls. And, reclaiming play for those who have outgrown recess. Guests: David Toomey - Professor of English, University of Massachusetts. Amherst and author of “Kingdom of Play: What Ball-Bouncing Octopuses, Belly-Flopping Monkeys, and Mud-Sliding Elephants Reveal About Life Itself.” Mariana Brussoni - Developmental psychologist who studies children's outdoor risky play, and professor at the University of British Columbia in the Faculty of Medicine Yoni Kallai - Interim director, head playworker and co-founder of play:groundNYC Peter Gray - Psychology researcher at Boston College and author of "Free to Learn: Why Unleashing the Instinct to Play Will Make Our Children Happier, More Self-Reliant, and Better Students for Life" Descripción en español Featuring music by Dewey Dellay and Jun Miyake Originally aired May 13, 2024 You can get early access to ad-free versions of every episode by joining us on Patreon.
