On this week’s show: NASA’s unprecedented asteroid-deflection mission, and making storage space for fresh water underground in Bangladesh First up on the podcast this week, News Intern Zack Savitsky joins host Sarah Crespi to talk about the upcoming NASA mission, dubbed the Double Asteroid Redirection Test, that aims to ram a vending machine–size spacecraft into an asteroid and test out ideas about planetary defense. Also this week, Sarah talks with Mohammad Shamsudduha, an associate professor in humanitarian science at University College London’s Institute for Risk and Disaster Reduction. He explains how millions of individual farmers in Bangladesh are creating the “Bengal water machine,” a giant underground sponge to soak up fresh water during monsoon season.

On this week’s show: After years of steep declines, researchers are investigating why malaria deaths have plateaued, and testing the stability of biosignatures in space First up on the podcast this week, freelance science journalist Leslie Roberts joins host Sarah Crespi to discuss why malaria deaths have plateaued in southern Africa, despite years of declines in deaths and billions of dollars spent. Leslie visited Mozambique on a global reporting grant from the Pulitzer Center where researchers are investigating the cause of the pause. Also this week, producer Kevin McLean talks with astrobiologists Mickael Baqué and Jean-Pierre de Vera of the German Aerospace Center. They discuss their Science Advances paper about an experiment on the International Space Station looking at the stability of biosignatures in space and what that means for our search for life on Mars.

On this week’s show: The U.S. government is partnering with academics to speed up the search for more than 80,000 soldiers who went missing in action, and how humans create their own “oxidation zone” in the air around them First up on the podcast this week, Tess Joosse is a former news intern here at Science and is now a freelance science journalist based in Madison, Wisconsin. Tess talks with host Sarah Crespi about attempts to use environmental DNA—free-floating DNA in soil or water—to help locate the remains of soldiers lost at sea. Also featured in this segment: University of Wisconsin, Madison, molecular biologist Bridget Ladell Woods Hole Oceanographic Institution marine biologist Kirstin Meyer-Kaiser Also this week, Nora Zannoni, a postdoctoral researcher in the atmospheric chemistry department at the Max Planck Institute for Chemistry, talks about people’s contributions to indoor chemistry. She chats with Sarah about why it’s important to go beyond studying the health effects of cleaning chemicals and gas stoves to explore how humans add their own bodies’ chemicals and reactions to the air we breathe. In a sponsored segment from Science/AAAS Custom Publishing Office, Sean Sanders, director and senior editor for Custom Publishing, interviews Benedetto Marelli, associate professor at MIT, about winning the BioInnovation Institute & Science Prize for Innovation and how he became an entrepreneur.
