Rodenticides are building up inside unintended targets, including birds, mammals, and insects; and bringing bioacoustics and artificial intelligence together for ecology First up this week, producer Kevin McLean and freelance science journalist Dina Fine Maron discuss the history of rodent control and how rat poisons are making their way into our ecosystem.   Next on the episode, host Sarah Crespi talks with Jeppe Rasmussen, a postdoctoral fellow in the behavior ecology group at the University of Copenhagen, about why researchers are training artificial intelligence to listen for seals, frogs, and whales.   Additional sound in this segment (some played, some mentioned):   ·      Monk seal noises care of Jeppe Rasmussen ·      Frog and crickets from Pond5  ·      Lyrebird sounds (Youtube link) ·      Cod fish sounds (Fishbase link)   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Kevin McLean, Sarah Crespi, Dina Fine Maron    Episode page: https://www.science.org/doi/10.1126/science.zq42hy5 Learn more about your ad choices.

First up this week, guest host Kevin McLean talks to freelance writer Andrew Zaleski about recent advancements in the world of synthetic blood. They discuss some of the failed attempts over the past century that led many to abandon the cause altogether, and a promising new option in the works called ErythroMer that is both shelf stable and can work on any blood type.   Next on the episode, producer Zakiya Whatley talks to Aaron Weimann from the University of Cambridge about the evolutionary history of the deadly bacterial pathogen Pseudomonas aeruginosa. They discuss how more than a century’s worth of samples from all over the world contributed to new insights on the emergence and expansion of the pathogen known for its ability to develop antimicrobial resistance.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Kevin McLean, Andrew Zaleski, Zakiya Whatley   Episode Page: https://www.science.org/doi/10.1126/science.z1jhbqi   About the Science Podcast: https://www.science.org/content/page/about-science-podcast   [Image: Matt Roth, Music: Jeffrey Cook and Nguyen Khoi Nguyen] Learn more about your ad choices.

Guest host Meagan Cantwell talks to Staff Writer Erik Stokstad about a new weapon against crop-destroying beetles. By making pesticides using RNA, farmers can target pests and their close relatives, leaving other creatures unharmed.  Next, freelance producer Katherine Irving talks to hydrologist Craig Brinkerhoff about a recent analysis of ephemeral streams—which are only around temporarily—throughout the United States. Despite their fleeting presence, Brinkerhoff and his colleagues found these streams play a major role in keeping rivers flowing and clean. Brinkerhoff is currently a postdoctoral fellow at Yale University, and completed this work as a Ph.D. student at the University of Massachusetts Amherst.   Finally, the next segment in our books series on a future to look forward to. Books host Angela Saini talks with author Rachel O’Dwyer about her recent book Tokens: The Future of Money in the Age of the Platform. They’ll discuss new and old ideas of currency, and what it means to have our identities tied to our money as we move toward a more cashless society.
