Today you learn why fish never quit wiggling,

how a donut shaped planet is technically possible and what researchers have learned from a woman who can't feel fear.

We'll also answer a listener question about why you can touch aluminum foil in a hot oven.

Stay tuned for the answer.

Let's satisfy some curiosity. New research. oil in a hot oven. Stay tuned for the answer.

Let's satisfy some curiosity.

New research shows a pretty good reason why fish never quit wiggling.

And here's a connection you might not have thought about.

This discovery demonstrates how robots built with

better sensors could interact with their environment more effectively.

Who knew that Wiggly Fish would help us figure out how to make better robots.

Yeah, as reported by Futurity, a new report published in current biology enhances our

understanding of what's called active sensing behaviors.

So like for humans, you're using active sensing when you feel around in the

dark for the bathroom light or you bobble an object up and down in your hands to

figure out how much it weighs. We do this kind of thing almost unconsciously and scientists haven't known

much about how and why we adjust our movements to respond to the sensory

feedback we get. To answer this question, researchers studied fish that generate a weak electric field around their bodies
