A different source of global warming, signs of a continentwide tradition of human sacrifice, and a virus that attacks the cholera bacteria   First up on the show this week, clearer skies might be accelerating global warming. Staff Writer Paul Voosen joins host Sarah Crespi to discuss how as air pollution is cleaned up, climate models need to consider the decrease in the planet’s reflectivity. Less reflectivity means Earth is absorbing more energy from the Sun and increased temps.   Also from the news team this week, we hear about how bones from across Europe suggest recurring Stone Age ritual killings. Contributing Correspondent Andrew Curry talks about how a method of murder used by the Italian Mafia today may have been used in sacrifices by early farmers, from Poland to the Iberian Peninsula.   Finally, Eric Nelson, an associate professor at the University of Florida’s Emerging Pathogens Institute, joins Sarah to talk about an infectious bacteria that’s fighting on two fronts. The bacterium that causes cholera—Vibrio cholerae—can be killed off with antibiotics but at the same time, it is hunted by a phage virus living inside the human gut. In a paper published in Science, Nelson and colleagues describe how we should think about phage as predator and bacteria as prey, in the savanna of our intestines. The ratio of predator to prey turns out to be important for the course of cholera infections.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Paul Voosen; Andrew Curry   Episode page: https://www.science.org/doi/10.1126/science.zhgw74e Learn more about your ad choices.

The James Webb Space Telescope was first conceived in the late 1980s. Now, more than 30 years later, it’s finally set to launch in December. After such a long a road, anticipation over what the telescope will contribute to astronomy is intense. Daniel Clery, a staff writer for Science, joins host Sarah Crespi to talk about what took so long and what we can expect after launch. You might have heard that Greenland sharks may live up to 400 years. But did you know that some Pacific rockfish can live to be more than 100? That’s true, even though other rockfish species only live about 10 years. Why such a range in life span? Greg Owens, assistant professor of biology at the University of Victoria, discusses his work looking for genes linked with longer life spans. This week’s episode was produced with help from Podigy.

Some 80 countries around the world add folic acid to their food supply to prevent birth defects that might happen because of a lack of the B vitamin—even among people too early in their pregnancies to know they are pregnant. This year, the United Kingdom decided to add the supplement to white flour. But it took almost 10 years of debate, and no countries in the European Union joined them in the change. Staff Writer Meredith Wadman joins host Sarah Crespi to discuss the ongoing folate debate. Last year, a highly anticipated tool for dating ancient materials was released: a new updated radiocarbon calibration curve. The curve, which describes how much carbon-14 was in the atmosphere at different times in the past 55,000 years, is essential to figuring out the age of organic materials such as wood or leather. Sarah talks with Tim Heaton, senior lecturer in the School of Mathematics and Statistics at the University of Sheffield, and Edouard Bard, a professor at the College of France, about how the curve was redrawn and what it means, both for archaeology and for our understanding of the processes that create radiocarbon in the first place—like solar flares and Earth’s magnetic fields.

There are massive telescopes that look far out into the cosmos, giant particle accelerators looking for ever tinier signals, gargantuan gravitational wave detectors that span kilometers of Earth—what about soil science? Where’s the big science project on deep soil? It’s coming soon. Staff Writer Erik Stokstad talks with host Sarah Crespi about plans for a new subsoil observatory to take us beyond topsoil. Wood is in some ways an ideal building material. You can grow it out of the ground. It’s not very heavy. It’s strong. But materials like metal and plastic have one up on wood in terms of flexibility. Plastic and metal can be melted and molded into complicated shapes. Could wood ever do this? Liangbing Hu, a professor in the department of materials science and engineering and director of the Center for Materials Innovation at the University of Maryland, College Park, talked with Sarah about making moldable wood in a new way. In a sponsored segment from Science/AAAS Custom Publishing Office, Sean Sanders, director and senior editor for the Custom Publishing office, interviews Michael Brehm, associate professor at UMass Chan Medical School Diabetes Center of Excellence, about how he is using humanized mouse models to study ways to modulate the body’s immune system as a pathway to treating type 1 diabetes.

This week we are covering the Science special issue on mass incarceration. Can a dog find a body? Sometimes. Can a dog indicate a body was in a spot a few months ago, even though it’s not there now? There’s not much scientific evidence to back up such claims. But in the United States, people are being sent to prison based on this type of evidence. Host Sarah Crespi talks with Peter Andrey Smith, a reporter and researcher based in Maine, about the science—or lack thereof—behind dog-sniff evidence. With 2 million people in jail or prison in the United States, it has become incredibly common to have a close relative behind bars. Sarah talks with Hedwig Lee, a sociologist at Washington University in St. Louis, about the consequences of mass incarceration for families of the incarcerated, from economic to social.  This week’s episode was produced with help from Podigy.

This week we’re dedicating the whole show to the 20th anniversary of the publication of the human genome. Today, about 30 million people have had their genomes sequenced. This remarkable progress has brought with it issues of data sharing, privacy, and inequality. Host Sarah Crespi spoke with a number of researchers about the state of genome science, starting with Yaniv Erlich, from the Efi Arazi School of Computer Science and CEO of Eleven Biotherapeutics, who talks about privacy in the age of easily obtainable genomes. Next up Charles Rotimi, director of the Center for Research on Genomics and Global Health at the National Human Genome Research Institute, discusses diversity—or lack thereof—in the field and what it means for the kinds of research that happens. Finally, Dorothy Roberts, professor in the departments of Africana studies and sociology and the law school at the University of Pennsylvania, talks about the seemingly never-ending project of disentangling race and genomes.

On its first day, the new Biden administration announced plans to recalculate the social cost of carbon—a way of estimating the economic toll of greenhouse gases. Staff Writer Paul Voosen and host Sarah Crespi discuss why this value is so important and how it will be determined.  Next up, Alison Barker, a postdoctoral researcher at the Max Delbrück Center for Molecular Medicine, talks with Sarah about the sounds of naked mole-rats. You may already know naked mole-rats are pain and cancer resistant—but did you know these eusocial mammals make little chirps to identify themselves as colony members? Can these learned local dialects make naked mole-rats a new research model for language learning? This week’s episode was produced with help from Podigy. Listen to previous podcasts.
