After a two-year hiatus, the Undark podcast returns with a new format and a new name: Entanglements. Join science journalists Brooke Borel and Anna Rothschild as they invite guests with both expertise and divergent opinions on some of the most contentious and politicized areas of science today, from vaccines and GMOs to deep sea mining, AI, and the origins of Covid. Their goal: To see if they can break through the discord and find common ground. Far from an exercise in false balance, Entanglements, like Undark, seeks to bring civil discussion — and a bit of fun and wonder — back to the intersection of science and culture.
