Optimism is often thought as a disposition, something you're born with or without. So can it be learned? On today's show, Maddie talks with Alix Spiegel, co-host of NPR's Invisibilia, about "learned optimism." We'll look at what it is, the research behind it, and how it might come in handy in certain circumstances, like maybe a global pandemic?

Black holes are one of the most beguiling objects in our universe. What are they exactly? How do they affect the universe? And what would it be like to fall into one? We venture beyond the point of no return with Yale astrophysicist Priyamvada Natarajan, into a fascinating world of black holes — where the laws of physics break down.

The pandemic has upended every aspect of our lives, including the disorienting way many of us have been perceiving time. It might feel like a day drags on, while a week (or month!) just flies by. We talk with Dean Buonomano, a professor of neurobiology and psychology at UCLA, about his research into how the brain tells time. We'll also ask him what's behind this pandemic time warp.

Crows have gotten a bad rap throughout history. Think about it. A group of them is called a "murder." To get some insight into crows and perhaps set the record straight, we talked to Kaeli Swift. She's a lecturer at the University of Washington and wrote her doctoral thesis on crow "funerals."
In an earlier version of this episode, we used the word "spooky" to describe crows. Because that word has a history of being used as a racial slur, we chose to replace it with the words "scary" and "creepy." Thanks to our listeners who helpfully pointed this out to us, and we apologize. You can learn more about this from our friends at Code Switch.
