Restoring land after dam removal, and phonons as a basis for quantum computing
First up on this week’s show, planting in the silty soil left behind after a dam is removed and reservoirs recede. Contributing Correspondent Warren Cornwall joins host Sarah Crespi to talk about the world's largest dam removal project and what ecologists are doing to revegetate 36 kilometers of new river edge.
Next up on the show, freelance producer and former guest Tanya Roussy. She talks with Andrew Cleland, a professor at the University of Chicago, about a Science paper from this summer on using the phonon—a quantum of sound energy—as the basis of quantum computers.

Folge vom 13.10.2023Mysterious objects beyond Neptune, and how wildfire pollution behaves indoorsThe Kuiper belt might be bigger than we thought, and managing the effects of wildfires on indoor pollution First up on this week’s show, the Kuiper belt—the circular field of icy bodies, including Pluto, that surrounds our Solar System—might be bigger than we thought. Staff Writer Paul Voosen joins host Sarah Crespi to discuss the distant Kuiper belt objects out past Neptune, and how they were identified by telescopes looking for new targets for a visit by the New Horizons spacecraft. Next up on the show, the impact of wildfire smoke indoors. Producer Kevin McLean talks with Delphine Farmer, a chemist at Colorado State University, about an experiment to measure where particulates and volatile organic compounds end up when they sneak inside during a wildfire event. Finally, in a sponsored segment from the Science/AAAS Custom Publishing Office, Jackie Oberst, associate editor for custom publishing, discusses with Jens Nielsen, CEO of the BioInnovation Institute—an international life science incubator in Copenhagen, Denmark—about the next big leap in biology: synthetic biology. This segment is sponsored by the BioInnovation Institute. This week’s episode was produced with help from Podigy.

Folge vom 05.10.2023How long can ancient DNA survive, and how much stuff do we need to escape poverty?Pushing ancient DNA past the Pleistocene, and linking agriculture to biodiversity and infectious disease First up on this week’s show, Staff Writer Erik Stokstad brings a host of fascinating stories, from the arrival of deadly avian flu in the Galápagos to measuring the effect of earthworms on our daily bread. He and host Sarah Crespi start off the segment discussing just how much stuff you need to avoid abject poverty and why measuring this value can help us balance human needs against planetary sustainability. Other stories from Erik mentioned in this segment: ● Elephant trunk’s ‘stunning’ microscopic musculature may explain its dexterity | Science ● ‘Mind-boggling’ sea creature spotted off Japan has finally been identified | Science Next up on the show, as part of a special issue on ancient DNA, freelance producer Katherine Irving talks with Love Dalén, a professor of evolutionary genomics at the Centre for Palaeogenetics at Stockholm University. They talk about the longevity of ancient DNA and what it would take to let us see back even further. See the whole ancient DNA special issue here.

Folge vom 28.09.2023Visiting utopias, fighting heat death, and making mysterious ‘dark earth’A book on utopias and gender roles, India looks to beat climate-induced heat in cities, and how ancient Amazonians improved the soil First up on this week’s show: the latest in our series of books on sex, gender, and science. Books host Angela Saini discusses Everyday Utopia: In Praise of Radical Alternatives to the Traditional Family Home with ethnographer Kristen Ghodsee, professor of Russian and Eastern European studies at the University of Pennsylvania. See this year’s whole series here. Also this week, as part of a special issue on climate change and health, host Sarah Crespi speaks with Vaishnavi Chandrashekhar, a freelance journalist based in Mumbai, India. They talk about how India is looking to avoid overheating cities in the coming decades, as climate change and urbanization collide. Finally, we hear about how ancient Amazonians created fertile “dark earth” on purpose. Sarah is joined by Morgan Schmidt, an archaeologist and geographer at the Federal University of Santa Catarina. They discuss recent research published in Science Advances on the mysterious rich soil that coincides with ancient ruins, which may still be produced by modern Indigenous people in Brazil.
