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   Learn more about your ad choices.

On this week’s show: Researchers are finding new ways to mitigate implicit bias in medical settings, and how toothed whales use distinct vocal registers for echolocation and communication First up this week: how to fight unconscious bias in the clinic. Staff Writer Rodrigo Pérez Ortega talks with host Sarah Crespi about how researchers are attempting to fight bias on many fronts—from online classes to machine learning to finding a biomarker for pain. Next up on the show: a close look at toothed whale vocalization. Though we have known for more than 50 years that toothed whales such as orcas, sperm whales, and dolphins make diverse and useful sounds, how these noises are produced by their bodies has not been well understood. Coen Elemans, a professor in biology and head of the sound communication and behavior group at the University of Southern Denmark, joins Sarah to talk about using endoscopy and high-speed cameras as well as tissue samples and tracking data to learn how they achieve such amazing feats of sound.

On this week’s show: Portable MRI scanners could revolutionize medical imaging, and pheromones offer a way to control flies that spread disease First up this week: shrinking MRI machines. Staff Writer Adrian Cho talks with host Sarah Crespi about how engineers and physicists are teaming up to make MRI machines smaller and cheaper. Next up on the show, the smell of tsetse fly love. Producer Kevin McLean talks with Shimaa Ebrahim, a postdoctoral researcher in the department of molecular, cellular, and developmental biology at Yale University, about understanding how tsetse flies use odors to attract one another and how this can be used to prevent the flies from transmitting diseases such as African sleeping sickness.   This week’s episode was produced with help from Podigy.
