On this week’s show: Compassion fatigue will strike most who care for lab animals, but addressing it is challenging. Also, overturning ideas about ocean circulation   First up this week: uncovering compassion fatigue in those who work with research animals—from cage cleaners to heads of entire animal facilities. Host Sarah Crespi and Online News Editor David Grimm discuss how to recognize the anxiety and depression that can be associated with this work and what some institutions are doing to help.   Featured in this segment: Preston Van Hooser Megan LaFollette Anneke Keizer   Next up on the show, a segment from the annual meeting of AAAS (which publishes Science) on overturning assumptions in ocean circulation. Physical oceanographer Susan Lozier, dean of the College of Sciences at the Georgia Institute of Technology, talks with producer Kevin McLean about the limitations of the ocean conveyor belt model, and how new tools have been giving us a much more accurate view of how water moves around the world.   This week’s episode was produced with help from Podigy.   About the Science Podcast   [Image: NASA/Goddard Space Flight Center Scientific Visualization Studio; Music: Jeffrey Cook]   [alt: Global sea surface currents and temperature with podcast symbol overlay]   Authors: Sarah Crespi; Kevin McLean; David Grimm   Episode page: https://www.science.org/doi/10.1126/science.adh4938   See omnystudio.com/listener for privacy information.
