First up on the podcast, Meagan Cantwell produced a segment with Contributing Correspondent Kai Kupferschmidt on the fight against deepfakes. Kupferschmidt talks with Hany Farid, professor at the University of California, Berkeley, about the never-ending battle against fake imagery and why Farid is not giving up. Next on the show, building a tough, bio-compatible capsule for engineered bacteria. Tetsuhiro Harimoto talks about the challenges of keeping living bacteria inside a hydrogel capsule and the advantages of using engineered bacteria as sensors and medicine dispensers inside the body. (Harimoto completed this work as a postdoc at Harvard University and will start as a professor at Cornell University in the fall.) This week’s episode was produced with help from Podigy.

From chatting with a stranger on the train to reaching out to an old friend, everyday social interactions make us happier than we realize. Yet many people avoid these moments because they expect them to feel awkward or uncomfortable. Nicholas Epley, PhD, author of ‘A Little More Social,’ discusses why people consistently underestimate how much they’ll enjoy all kinds of social interactions; the psychology behind small talk and deep conversations; how technology is changing the way we connect; and why even brief moments of connection can improve our happiness, health and well-being.
