First up, science journalist Julia Rosen talks with host Sarah Crespi about a growing fleet of radar satellites that will soon be able to detect minute rises and drops of Earth’s surface—from a gently deflating volcano to a water-swollen field—on a daily basis. Sarah also talks with Hui Cao, a professor of applied physics at Yale University, about a new way to generate enormous streams of random numbers faster than ever before, using a tiny laser that can fit on a computer chip.

Science Staff Writer Jon Cohen joins host Sarah Crespi to take on some of big questions about the COVID-19 vaccines, such as: Do they stop transmission? Will we need boosters? When will life get back to “normal.” Sarah also talks with Anders Johansen, professor of planetary sciences and planet formation at the University of Copenhagen, about his Science Advances paper on a new theory for the formation of rocky planets in our Solar System. Instead of emerging out of ever-larger collisions of protoplanets, the new idea is that terrestrial planets like Earth and Mars formed from the buildup of many small pebbles.

Science journalist Rachel Cernansky joins host Sarah Crespi to talk about progress on Africa’s Great Green Wall project and the important difference between planting and growing a tree. Sarah also talks with Václav Kuna, a postdoctoral researcher at the Institute of Geophysics of the Czech Academy of Sciences, about using loud and long songs from fin whales to image structures under the ocean floor.

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.

Online News Editor David Grimm joins host Sarah Crespi to discuss a controversial new paper that estimates how many rodents are used in research in the United States each year. Though there is no official number, the paper suggests there might be more than 100 million rats and mice housed in research facilities in the country—doubling or even tripling some earlier estimates. Next, Staff Writer Jennifer Couzin-Frankel talks with Sarah about a new theory behind the cause of irritable bowel syndrome—that it might be a localized allergic reaction in the gut. Sarah also chats with Taline Kazandjian, a postdoctoral research associate at the Centre for Snakebite Research & Interventions in Liverpool, U.K., about how the venom from spitting cobras has evolved to cause maximum pain and why these snakes might have developed the same defense mechanism three different times.

Science Senior Correspondent Daniel Clery regales host Sarah Crespi with tales about the most important work to come from 57 years of research at the now-defunct Arecibo Observatory and plans for the future of the site. Sarah also talks with Toman Barsbai, an associate professor in the school of economics at the University of Bristol, about the influence of ecology on human behavior—can we figure out how many of our behaviors are related to the different environments where we live? Barsbai and colleagues took on this question by comparing behaviors around finding food, reproduction, and social hierarchy in three groups of animals living in the same places: foraging humans, nonhuman mammals, and birds.

Freelance journalist Gabriel Popkin and host Sarah Crespi discuss what will happen to ash trees in the United States as federal regulators announce dropping quarantine measures meant to control the emerald ash borer—a devastating pest that has killed tens of millions of trees since 2002. Instead of quarantines, the government will use tiny wasps known to kill the invasive beetles in hopes of saving the ash. Sarah also talks with Pavel Chvykov, a postdoctoral researcher at the Massachusetts Institute of Technology, about the principles for organizing active matter—things like ant bridges, bird flocks, or little swarms of robots.  This week’s episode was produced with help from Podigy.

We kick off our first episode of 2021 by looking at future trends in policy and research with host Meagan Cantwell and several Science news writers. Ann Gibbons talks about upcoming studies that elucidate social ties among ancient humans, Jeffrey Mervis discusses relations between the United States and China, and Paul Voosen gives a rundown of two Mars rover landings. In research news, Meagan Cantwell talks with Leda Kobziar, an associate professor of wildland fire science at the University of Idaho, Moscow, about the living component of wildfire smoke—microbes. The bacteria and fungi that hitch a ride on smoke can impact both human health and ecosystems—but Kobziar says much more research is needed. This week’s episode was produced with help from Podigy.

Our last episode of the year is a celebration of science in 2020. First, host Sarah Crespi talks with Online News Editor David Grimm about some of the top online news stories of the year—from how undertaker bees detect the dead to the first board game of death. (It’s not as grim as it sounds.) Sarah then talks with Online News Editor Catherine Matacic about the Breakthrough of the Year, scientific breakdowns, and some of the runners-up—amazing accomplishments in science achieved in the face of a global pandemic. Finally, Book Review Editor Valerie Thompson joins Sarah to discuss highlights from the books section—on topics as varied as eating wild foods to how the materials we make end up shaping us.
