What Alaska’s eroding coastline says about Earth’s future, and how Yellowstone ravens use their smarts to find wolf kills

First up on the podcast, freelance journalist Evan Howell traveled to Cape Blossom, Alaska, where the receding coastline has revealed an ancient trove of glacial ice that may have survived for 350,000 years—making it the oldest ice in the Northern Hemisphere. Now researchers just need to figure out how to date it. Next on the show, tracking wolves and ravens in Yellowstone National Park shows the birds don’t follow the wolves in hope of a meal, but instead remember and revisit frequent wolf kill sites. Matthias-Claudio Loretto, assistant professor in the Research Institute of Wildlife Ecology at the University of Veterinary Medicine Vienna, discusses how this might change the way we think about scavengers’ strategies for finding their ephemeral food sources. Finally, Claire Bedbrook, the Helen Hay Whitney and Wu Tsai neuroscience postdoctoral fellow at Stanford University, discusses her work tracking African turquoise killifish over their life span. By capturing behaviors over the course of the fish’s entire lives, her team was able to observe behaviors that could be used to predict whether a fish would live a short or long life.
