A roundup of online news stories featuring animals, and researchers get crows to “count” to four   This week’s show is all animals all the time. First, Online News Editor Dave Grimm joins host Sarah Crespi to discuss stepping on venomous snakes for science, hunting ice age cave bears, and demolishing lizardlike buildings.   Next, producer Kevin McLean talks with Diana Liao, a postdoctoral researcher at the University of Tübingen, about teaching crows to count out loud. They discuss the complexity of this behavior and how, like the famous band, these counting corvids have all the right vocal skills to do it.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Kevin McLean; David Grimm   Episode page: https://www.science.org/doi/10.1126/science.ztje4j6 Learn more about your ad choices.

On this week’s show: What happens when the body’s own immune system attacks the brain, and how otters’ use of tools expands their diet   First on the show this week, when rogue antibodies attack the brain, patients can show bizarre symptoms—from extreme thirst, to sleep deprivation, to outright psychosis. Contributing Correspondent Richard Stone joins host Sarah Crespi to discuss the hunt for biomarkers and treatments for this cluster of autoimmune disorders that were once mistaken for schizophrenia or even demonic possession.   Next on this episode, producer Katherine Irving talks with Chris Law, an evolutionary biologist at the University of Washington and the University of Texas at Austin, about how sea otters gain energy benefits (and dental benefits) when they use tools to tackle tougher prey such as snails or large clams.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Richard Stone; Katherine Irving Episode page: https://www.science.org/doi/10.1126/science.z4pdg62 Learn more about your ad choices.

Jupiter’s moon Io has likely been volcanically active since the start of the Solar System, and a proposal to safeguard healthy human subjects in clinical trials First on the show this week, a look at proposed protections for healthy human subjects, particularly in phase 1 clinical trials. Deputy News Editor Martin Enserink joins host Sarah Crespi to discuss the risks healthy participants face when involved in early testing of drugs for safety and tolerance. Then, we hear about a project to establish a set of global standards initiated by the Ethics Committee of France’s national biomedical research agency, INSERM.   Next on this episode, a peek at the history of the most volcanically active body in the Solar System, Jupiter’s moon Io. Because the surface of Io is constantly being remodeled by its many volcanoes, it’s difficult to study its past by looking at craters or other landmarks. Katherine de Kleer, assistant professor of planetary science and astronomy at the California Institute of Technology, talks about using isotopic ratios in the moon’s atmosphere to estimate how long it’s been spewing matter into space.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Martin Enserink   Episode page: https://www.science.org/doi/10.1126/science.zyq2ig8 Learn more about your ad choices.
