Science Podcast: Dire Wolf Extinction, Pluto’s Blue Haze & Mice Empathy

DNA clues point to how dire wolves went extinct, and a round-up of the main impacts of Brexit on science.

In this episode:

00:45 Dire wolf DNA

Dire wolves were huge predators that commonly roamed across North America before disappearing around 13,000 years ago. Despite the existence of a large number of dire wolf fossils, questions remain about why this species went extinct and how they relate to other wolf species. Now, using DNA and protein analysis, researchers are getting a better understanding of what happened to these extinct predators.

13:31 Post-Brexit science

In December, a last minute trade-deal between the UK and EU clarified what the future relationship between the two regions would look like, after Brexit. We discuss the implications of this trade-deal for science funding, the movement of researchers, and data sharing.

Top New Science Podcasts: Pluto’s Dark Side Yields Dwarf Planet’s Secrets

Nature PodcastsIn 2015, after a nine-and-a-half-year journey, NASA’s New Horizons spacecraft raced past Pluto, beaming images of the dwarf planet back to Earth.

Five years after the mission, researchers are poring over images of Pluto’s far-side, which was shrouded in shadow during New Horizon’s flypast. They hope that these images will help give a better understanding of how Pluto was born and even whether a hidden ocean resides beneath the world’s icy crust.
