Linking cat domestication to ancient cult sacrifices, and watching aurorae wander
First up on the podcast, Online News Editor David Grimm joins host Sarah Crespi to talk about how an Egyptian cult that killed cats may have also tamed them.
Next on the show, we hear about when the aurorae wandered. About 41,000 years ago, Earth’s magnetic poles took an excursion. They began to move equatorward and decreased in strength to one-tenth their modern levels. Agnit Mukhopadhyay, a research affiliate at the University of Michigan, talks about how his group mapped these magnetic changes, and what it would be like if such a big change took place today.
This week’s episode was produced with help from Podigy.
