Weekly podcasts from Science Magazine, the world's leading journal of original scientific research, global news, and commentary.

A millennium ago, Viking navigators may have used crystals known as “sunstones” to navigate between Norway and Greenland. Sarah Crespi talks with Online News Editor David Grimm about how one might use a crystal to figure out where they are.


Sarah also interviews freelancer Danna Staaf about her piece on sedating cephalopods. Until recently, researchers working with octopuses and squids faced the dilemma of not knowing whether the animals were truly sedated or whether only their ability to respond had been suppressed.


This week’s episode was edited by Podigy.
