Mindscape with Sean Carroll. Interview format with a wide range of accomplished guests and interesting topics -- including physics from time to time, as the host is a physicist.

Making Sense with Sam Harris (formerly called Waking Up). He has some really great episodes with intellectually stimulating content and guests, but occasionally he misses the mark or gets caught up in some unnecessary controversy. The episode summaries are very helpful for choosing which episodes are valuable to listen to.

Meta note: I'm a huge fan of the long-interview format which gives a unique opportunity to have these expansive discussions on complex and interesting in the public space. I'd love to find more like the above.
