Animals

You may have noticed some strong smells coming from your feet, your friend's breath, or your brother's armpit. Where do these body odors come from? We'll meet the microscopic organisms responsible and visit the kingdom of Footsteros. We'll also find out why we might find these naturally occurring smells so disgusting. Plus: A brand new Moment of Um answers the question: Why do stink bugs stink?

Most plants get the energy and nutrients they need from water, sunlight, air and soil. But carnivorous plants get key nutrients from a different source: bugs. We’ll find out how they do it and talk about the mystery of how venus fly traps snap shut. Plus: Two gardeners – one very experienced and one just starting out – offer their tips for growing venus fly traps.

So that’s plants, but what about animals? Carnivores are animals that only eat other animals – so how do they get the vitamins, minerals and fiber that we humans get from eating plants? We take a trip to a salad bar with some animal pals to find out.

In this episode, we climb up, down and all around our evolutionary family tree. When did we branch off from our more ape-like ancestors? And will we evolve one day into a different species altogether? We'll meet a bearded scientist from 160 years ago (no, not Charles Darwin) and eat some sundaes (thanks lactase persistence!). Plus a brand new Moment of Um answers the question: Do insects have the same blood as humans?

We are very vocal about this episode, and that’s because it’s all about voices. We look into how our bodies produce sound and talk to a voice recognition expert. And we find out what’s happening when helium enters the equation. Plus, humans don’t have the voice market cornered -- what about other animals? We’ll drop in on a few creatures and find out how they make sounds too. All that plus a brand new Mystery Sound and berry delicious Moment of Um.

Last week, we heard about the tale of the Cuyahoga River -- a river in Ohio that caught on fire multiple times because it was so polluted. The river is now doing much better, but beyond the fact that it’s not on currently fire -- how do we actually know it’s healthier today? That’s when being a water detective really comes in handy. Plus: Our Moment of Um answers the question: "Why do dogs wag their tails?"

For humans, being left-handed or right-handed can definitely affect the way we experience life. Usually, that mismatch is just a minor nuisance — but sometimes, sidedness can change the future of an entire species, as is the case for Sandy.

Two of our planet’s most amazing animals go head to head in our latest debate.

If you’ve ever seen a dog, you know they like to sniff — the ground, people, each other’s butts. They like to smell just about everything. But why? We’re digging into the science of smell and how dogs are able to decode things we can’t even begin to imagine.

Your body is making and using electricity all the time — but how do we do it? We’ll take a look at how bioelectricity helps our brain sends signals and our hearts pump blood. And we’ll learn about some amazing animals that use electricity in weird and wild ways.

What superpowers does our skin have to repair itself? And what about other animals like salamanders that can do some pretty extreme healing? We’re going under the skin for this one.

The sea lamprey, with its concentric rows of sharp teeth, is part vampire and part alien invader. Would you let it suction to your arm? Reporter Dan Kraker did. Find out if he lived to tell about it.

Most animals fart. And some animals put those farts to work.
