ROTT: Our second story is about space, Scott, and it looks at quasars, which are these super bright lights from ancient galaxies that can tell us more about the formation of the universe.

BARBER: And the final study looks at the unfortunate eating habits of California wolves.

DETROW: Let's start with the insects, the many, many, many insects.

MELISSA GUZMAN: And they're really diverse. There are these, like, tiny wasps, like, really, really tiny.
