So if this worked, who knows what astronauts could get into next when fermenting stuff in space? Maybe sourdough, kimchi. I guess there's also stinky cheese, but I feel like if I were an astronaut, I'd be a little worried about that one. Personal choice, though.

And just a reminder, bats navigate using sound. It's called echolocation. They send out a vocalization, a call. And then they listen for its echo off objects in their path. But when a million bats are all flying out of a cave together, that's a lot of bat calls that could get mixed up. Here, let's take a listen. Oh, my gosh.

Yes, yes. Aya did this work while at Tel Aviv University in Israel. She and her team also used some new tracking technology using these little tags they put on bats to monitor their location. And when they combined acoustic data from these personal bat microphones, they figured out how a bat changed its call based on the density of bats around them.

which they reported on in the proceedings of the National Academy of Sciences this week. Well, you've got to tell me, how do they change their calls?

Yeah, Aya says that understanding how bats navigate could help engineers design flying robots that could swarm, which might be helpful in agriculture or environmental sensing.
