A Question Of Biggitude: What's The Largest Creature On Earth?

Thursday, May 08, 2014

What's the biggest living thing on Earth? I can think of two. I'm not sure which is biggest, but neither of them is a blue whale. These are weirder. Much, much weirder.

One is a tree. The other eats trees.

This is the tree.

Draw My Left! No, No, My Other Left! A Hidden Bias In Art History Revealed

Wednesday, May 07, 2014

Look at this guy.

He is half-smiley, half-frowny. I drew the mouth carefully to make it equal parts sad and happy.

But when you look at him — take him in whole — would you say he's having a good day or a bad day?

Listen To These Lovely Cats. No, Actually, Don't

Sunday, May 04, 2014

They are so sleek, so graceful, with such gorgeous eyes, tufted ears — but then they speak. And you think, "Oh no! Why? Why?"

"Oh, evolution," writes Mara Grunbaum in her new, about-to-come-out bookWTF Evolution, "You were doing so well with the lynx. You made it a fierce and graceful hunter, you gave it a luxurious spotted coat, you gave it pretty yellow eyes and tufted ears — and ...

'Wassup, Sheep?' He Asked

Friday, May 02, 2014

One man is facing a few hundred sheep. He has questions. When he shouts to them, the sheep — surprisingly — answer back. It's a very lively back and forth, with one obvious problem. I don't trust these sheep. Their answer to his "Are you happy?" question seemed oddly, even ...

'Wassup, Sheep?' He Asked

Friday, May 02, 2014

How come so many species of domesticated animals — dogs, pigs, cows, ducks, geese, rats, horses — have smaller brains than their wild ancestors? Oh, and humans too!

Plants Talk. Plants Listen. Here's How

Tuesday, April 29, 2014

They don't have eyes. Or ears. Or what we would call a nervous system. But plants can talk. And they listen. Let me show you how.

First, we'll need a plant eater. This one's perfect: It's an aphid, a hungry little critter who loves to munch on fresh, green leaves ...

Come Dance With Me

Saturday, April 26, 2014

One song, danced two totally different ways. First, two dancers who sculpt the giddiness, the beats, onto their rhyming bodies. Then a second version, this time, a crazy story. Vive la difference!

Music That Burns, Literally

Wednesday, April 23, 2014

Take Beyonce. Take Sinatra. Take whomever you love and set them on fire — with a "Pyro Board." It plays music by pulsing the beats in flame, and when the singer hits a high note — stand back.
