Learning about humans by watching chimps
If you've ever looked into the intelligent eyes of a chimpanzee at the zoo, you may have had the feeling that this animal was looking back at you with the same type of curiosity. Our two species have many similarities. We find creative ways to solve problems. We nurture and make each other feel better. We're also capable of being bullies.

See-through ribbons are stronger than steel and much more versatile
Imagine rolling your TV up and putting in your backpack to take with you somewhere. Or pressing a button on a snowy day and having all the snow melt quickly from your windows. These possibilities may become real before long, thanks to a bunch of long, bendy molecules called "carbon nanotubes."

Knotted strings, not written records, for the ancient Inkans
For decades, archeologists exploring the remains of the Inkan empire, an ancient civilization in western South America, have found mysterious clusters of knotted strings called "khipu." Because they are so common, khipu appear to be quite important, but what do they mean and what were they used for?

Eggs tell story of baby dinosaurs' first steps
Scientists have discovered fossilized eggs containing developing dinosaurs that probably started out moving around on all four limbs before learning to walk only on only two legs -- kind of like people.

Special delivery: How seabirds bring pollution to the Arctic
The arctic landscape is beautifully pristine. You won't see many factories, highways or other signs of industrial civilization. So why do researchers keep finding high levels of pollution there?

Blind sea creature hunts with a light
The deep sea is a seriously dark place, so when a light shows up, even a tiny one, fish will swim up for a closer look. That seems to be the strategy behind the glowing red spots used by a relative of the jellyfish, called Erenna. Scientists have just discovered that these creatures have glowing red dots in their tentacles, which are probably used to lure fishy prey.

Bird code: what chickadees are really saying to each other
When a tiny chickadee songbird spots an owl, hawk, or other predator perched nearby, it makes a warning call that sounds like its name ("chick-a-dee-dee-dee"). Other chickadees within earshot then swarm together and mob the predator, usually harassing it so that it flies away.

Mucus balloons solve an ocean mystery
Some tadpole-sized ocean animals live in houses made of almost the very same stuff that leaks out of your nose when you have a cold. As researchers have just discovered, these mucus houses help solve the mystery of how creatures at the bottom of the ocean get enough food.

Young canaries sing surprising songs
It's easy to get little kids to say something funny like "Big Bird is the President of the United States" because they don't know what the sentence means. They just repeat the sounds.

Fish TV and a new way to swim
How do tiny sea creatures, many only one-tenth the size of a grain of rice, stay together to form the dense patches that whales and other creatures rely on for food? Why don't these crowded groupings of animals break up by sinking deep or floating to the surface?

How an uninvited bird guest fools its hosts
When a female Horsfield's hawk-cuckoo lays an egg, she leaves it in the nest of other birds, where the chick will be raised by foster parents. Animals have many different strategies for survival, and the hawk-cuckoo chick's isn't particularly kind. It pushes the other baby birds out of the nest, so that it can receive all the attention from its foster parents.

Taste test for ants
Scientists put a bunch of ants through a taste test. No. The scientists didn't taste the ants. The ants did the tasting. The ants wandered around an "ant cafeteria" where they could eat any of the natural or artificial sweet foods they wanted.

Dinosaur eggs discovered inside mother
Scientists have discovered a dinosaur that died right before it laid two eggs. Finding dinosaur eggs inside the female, in almost the same position they were in when she died, might answer some tough questions about dinosaur egg-laying.

A surprise inside a T. Rex fossil
When scientists looked inside the leg bone of a recently discovered Tyrannosaurus rex fossil, they found something they weren't expecting. Typically, only the hard parts of an animal, like the bones, are preserved as fossils. This T. rex fossil, however, contained some beautifully preserved soft tissue inside the bone, where the marrow once was.

'Protein police' search your food
When you eat beans and rice, you make the "protein police" in your brain happy because you are eating a meal that supplies the ingredients your body needs to make proteins. These protein ingredients are called "amino acids."
