International News Editor Martin Enserink shares the latest from our reporters covering coronavirus. And finally, from a recording made at this year’s AAAS annual meeting, host Meagan Cantwell talks with Jill Tarter, chair emeritus at the SETI Institute, about the newest technologies being used to search for alien life, what a positive signal would look like, and how to inform the public if extraterrestrial life ever were detected.

This week on the podcast, Contributing Correspondent Lizzie Wade joins host Sarah Crespi to discuss a turning point for one ancient Mesoamerican city: Tikal. On 16 January 378 C.E., the Maya city lost its leader and the replacement may have been a stranger. We know from writings that the new leader wore the garb of another culture—the Teotihuacan—who lived in a giant city 1000 kilometers away. But was this new ruler of a Maya city really from a separate culture? New techniques being used at the Tikal and Teotihuacan sites have revealed conflicting evidence as to whether Teotihuacan really held sway over a much larger region than previously estimated.   Sarah also talks with Rashid Sumaila, professor and Canada research chair in interdisciplinary ocean and fisheries economics at the University of British Columbia, Vancouver’s Institute for the Oceans and Fisheries. You may have heard of illegal fishing being bad for the environment or bad for maintaining fisheries—but as Sumaila and colleagues report this week in Science Advances, the illegal fishing trade is also incredibly costly—with gross revenues of between $8.9 billion and $17.2 billion each year.    In the books segment this month, Kiki Sanford interviews Gaia Vince about her new book Transcendence How Humans Evolved through Fire, Language, Beauty, and Time.   This week’s episode was edited by Podigy.   Listen to previous podcasts.   About the Science Podcast   Download a transcript (PDF).  ++   [Image: Christian Hipólito; Music: Jeffrey Cook] Learn more about your ad choices.

On this week’s show, staff writer Robert F. Service talks with host Sarah Crespi about manipulating microbes to make them produce building materials like bricks—and walls that can take toxins out of the air.   Sarah also talks with Paul Davids, principal member of the technical staff in applied photonics & microsystems at Sandia National Laboratories, about an innovation in converting waste heat to electricity that uses similar materials to solar cells but depends on quantum tunneling.   And in a bonus segment, producer Meagan Cantwell talks with online news editor David Grimm on  stage at the AAAS annual meeting in Seattle. They discuss how wildfires can harm your lungs, crime rates in so-called sanctuary states, and how factors such as your gender and country of origin influence how much trust you put in science.   This week’s episode was edited by Podigy.   Listen to previous podcasts   About the Science Podcast   Download a transcript (PDF) Learn more about your ad choices.
