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.

The future of PCB-laden orca whales, and doing genomics work with Indigenous people

Science has often treated Indigenous people as resources for research—especially when it comes to genomics. Now, Indigenous people are exploring how this type of study can be conducted in a way that r...

Metaresearchers take on meta-analyses, and hoary old myths about science

Metaresearchers take on meta-analyses, and hoary old myths about science

Meta-analyses—structured analyses of many studies on the same topic—were once seen as objective and definitive projects that helped sort out conflicts amongst smaller studies. These days, thousands of...

The youngest sex chromosomes on the block, and how to test a Zika vaccine without Zika cases

Strawberries had both male and female parts, like most plants, until several million years ago. This may seem like a long time ago, but it actually means strawberries have some of the youngest sex chr...

Should we prioritize which endangered species to save, and why were chemists baffled by soot for so long?

Should we prioritize which endangered species to save, and why were chemists baffled by soot for so long?

We are in the middle of what some scientists are calling the sixth mass extinction and not all at-risk species can be saved. That’s causing some conservationists to say we need to start thinking about...

Sending flocks of tiny satellites out past Earth orbit and solving the irrigation efficiency paradox

Small satellites—about the size of a briefcase—have been hitching rides on rockets to lower Earth orbit for decades. Now, because of their low cost and ease of launching, governments and private compa...
