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.

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.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi, Vaishnavi Chandrashekhar, Angela Saini    Episode page: https://www.science.org/doi/10.1126/science.adl0606 Learn more about your ad choices.

The key to shrinking cartels is cutting recruitment, and a roundup of books, video games, movies, and more   First up on this week’s show: modeling Mexico’s cartels. Rafael Prieto-Curiel, a postdoctoral research fellow at the Complexity Science Hub in Vienna, joins host Sarah Crespi to discuss how modeling cartel activities can help us understand the impact of potential interventions such as increased policing or reducing gang recruitment.    Lisa Sanchez, executive director of México Unido Contra la Delincuencia, talks with Sarah about just how difficult it would be to make the model results—which show that reducing recruitment is key—a reality.   Next on the show, Science books editor Valerie Thompson and books intern Jamie Dickman discuss a huge selection of science books, movies, video games, and even new exhibits—all due out this fall.
