Keeping water out of the stratosphere could be a low-risk geoengineering approach, and using magnets to drive medical robots inside the body   First up this week, a new approach to slowing climate change: dehydrating the stratosphere. Staff Writer Paul Voosen joins host Sarah Crespi to discuss the risks and advantages of this geoengineering technique.   Next on the show, Science Robotics Editor Amos Matsiko gives a run-down of papers in a special series on magnetic robots in medicine. Matsiko and Crespi also discuss how close old science fiction books came to predicting modern medical robots’ abilities.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Paul Voosen; Amos Matsiko   Episode page: https://www.science.org/doi/10.1126/science.zvvddhw Learn more about your ad choices.

On this week’s show: Factors that pushed snakes to evolve so many different habitats and lifestyles, and news from the AAAS annual meeting   First up on the show this week, news from this year’s annual meeting of AAAS (publisher of Science) in Denver. News intern Sean Cummings talks with Danielle Wood, director of the Space Enabled Research Group at the Massachusetts Institute of Technology, about the sustainable use of orbital space or how space exploration and research can benefit everyone.   And Newsletter Editor Christie Wilcox joins host Sarah Crespi with an extravaganza of meeting stories including a chat with some of the authors of this year’s Newcomb Cleveland Prize–winning Science paper on how horses spread across North America.   Voices in this segment:   William Taylor, assistant professor and curator of archaeology at the University of Colorado Boulder’s Museum of Natural History   Ludovic Orlando, director of the Centre for Anthropobiology and Genomics of Toulouse   University of Oklahoma archaeologists Sarah Trabert and Brandi Bethke   Yvette Running Horse Collin, post-doctoral researcher Paul Sabatier University (Toulouse III)     Next on the show: What makes snakes so special? Freelance producer Ariana Remmel talks with Daniel Rabosky, professor in ecology and evolutionary biology at the University of Michigan, about the drivers for all the different ways snakes have specialized—from spitting venom to sensing heat.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Ariana Remmel; Christie Wilcox; Sean Cummings   Episode page: https://www.science.org/doi/10.1126/science.zabhbwe Learn more about your ad choices.
